Posted by: DADDYJIM

I am the goofball? who just bought the supercharger off ebay. http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWN%3AIT
I don't what will come of this but we will start in the next couple of weeks. I will keep you posted.

Posted by: SoonerLS

You'll want to watch QuikLS's progress. He's currently working with the guy from whom you bought that unit on developing a SC kit for the LS. As a matter of fact, Quik's working on it today...

Good luck!

Posted by: Quik LS

yep - start at 10:30am this morning taking a break at 1pm

so here is the progress in 2 1/2 hours....
stopping for a beer...

Posted by: pepperman

Posted by: JoeyLincolnMK8

welcome to LvC

looking good quik, keep up the good work!

Posted by: Quik LS

ok - finished beer
- removed the cooling tower
- now to work on the new intake

Posted by: mcafferty

my god your crazy. Keep us posted Quick

Posted by: DADDYJIM

He is my HERO

Posted by: itsnotmydaddys

CRAZY, but thats y we love quik. he knows sh!t that the producers of the LS font even know, :but what does he look like?" POST QUIK PLEASE!!!!!!!!!!

Posted by: didjital|

Hey Quick, better put that front plate back on!!!

-- Don't want any unncessary attention on you when your testing the SC out!!

Posted by: pepperman

Post pics when you are done!!!!!

Posted by: SurfjaxLS

Looking good. Let us know when it's done. I'll be on the lookout for some nice long tire marks around Austin when you finish.

Posted by: Quik LS

Thanks guys -
- still working on it today - probably most of this week (finally have a week in town)

- yeah - I finally took my front plate off for some car calendar shootings - like it much better - but will never pass inspection without it. Just I'll put it on during the drive to inspection....

- no tire burns from me - I just put some Goodyear F1 GS-D3 on it - seem nice. They would dyno my car since the BG RE750s were past the wear bars.....

yikes - thatr's my 4th set of tire and 3rd set of brake in 42,000 miles.....

One would think that you'd be too busy driving during the drive to the inspection, but, hey, whatever floats your boat.

Posted by: DADDYJIM

What are you doing with exhaust? I have magnaflows but was thinking about doing cats and everything. what is the size of the tubes at the exhaust manifold. No room for headers that I can see. Any ideas from anyone?

Posted by: Quik LS

I went to a local shop and made a custom cat-back - 2.5" piping with few bends, magnaflow x-pipe, flowmaster 40s, magnaflow quad tips....

reports from the prototypes it that 3" piping lost too much back pressure.

Posted by: Quik LS

ok - here's where I am leaving off for the night.....

- injectors, fuel rail and mounting moved over to the new manifold
- test fitted all the cooling re-routing, bought gaskets
- transfered the LS iac valve onto the new set-up, built block plate
- worked on the TPS..... gonna need some work... the LS uses a typical late model Ford TPS with a WPT-170 connector - but is mounted vertically.... I need one mounted horizontally..... the search is on...

Posted by: lexdiamondz10304

Whoa this thing looks serious.. any est. HP numbers?

Posted by: LikeNew02

will you cut a hole in the hood for the blower

Posted by: Joeychgo

SWEET! Ive been dyin to see this installation

Posted by: pepperman

Damn that thing is going to be Smokin Hot!!

Fixed the TPS issue - the 1998 3.8L Mustang uses the same TPS as the T-bird SC but has the WPT-170 connector that the LS uses....

Posted by: JohnnyB

Wow, good find Quik.

Posted by: monnieh

You rule Quick. I am so ready to put this SC on my LSE.

Posted by: Quik LS

Quik update....

- got more of the intake built - TPS and IAC on (built a blocking plate to fit the IAC to the T-Bird Throttle)
- made some intake gaskets
- removed and plugged the coolant line from below the coolant tree to the throttle body
- added the new thermostat housing (to re-direct the lines around the SC snout)
- removed and plugged the CHT sensor - moved it into the cooling bridge
- added the new cooling bridge
- found and used standard gaskets for all the cooling

gonna be a late night tonight....

Posted by: Kelleyo

Awesome. You sure like Blue too eh?

Posted by: GrayGhost1

What I want to know is how does your wife like that SC in the kitchen?

Posted by: Quik LS

I've learned not to ask......

actually - I have a lot of 'cookies in the jar' ....

Posted by: GrayGhost1

Yeah, well you should see my dining room! Looks like a FedEx hub! And the wife REALLY loves that!

Posted by: beaups

sorry for ignorance what is "CHT" you refer to in the pictures? also those black things running to the tops of the heads on each side, are those the knock sensors? Just curious, wondered where they were located.

Posted by: mdrobnak

A "CHT" is a Cylinder Head Temperature sensor.

-Matt

Posted by: beaups

and those do what? do they drive the temperature gauge?

Posted by: mdrobnak

It's used by the PCM (Powertrain Control Module - AKA computer) for various decisions such as start up fueling, spark advance, quite a few things actually.

-Matt

Posted by: SilverLS

INSANE!!!!! I WANT ONE for my V6!!!!

Posted by: beaups

Quik - what are you doing for FUEL? 9th injector? bigger injectors? separate fuel controller? I'd love to know!

Posted by: mdrobnak

Probably using the stock computer and bigger injectors - and a tune, of course.

-Matt

Posted by: davidanthony21

Great job, I wouldn't even know where to begin with a project like this. Maybe I will spot your LS sometime when I party in Austin (I live in San Antonio).

Posted by: Motts

Any update on this... yea yea I'm still lurking around..

Just recently purchased 50 Acres in Napa Valley.

Purchased a vineyard and had a house built.

Posted by: Quik LS

sorry - been traveling during the week....

So day 5:
- have the belt routing backet in place
- have the manifold in

...more to come today...

Posted by: JoeyLincolnMK8

looking really good quik! i can not wait to see when it is done.

Posted by: mdrobnak

Hey Quik,

Looking great so far. Can't wait to hear how it comes out.

Could you ask the guy you're working with how difficult it would be to modify the manifold for something say ... a little bigger? :-) Like a Kenne Bell perhaps.

-Matt

no need. This M90 can make much more power than we need - I'm only running about 5lbs of boost - seeing how we are already at 10.55:1 compression.

but introduce some different intercooling (I'm only using a front mount) and move the pulley down to 8lbs of boost......

On stock internals - not sure where the upper limit is.....

Posted by: mdrobnak

Well, twin screw vs roots, twin screw should get the temps down a little, and make more power...

Btw, Jag runs 9.1:1 on their S-type R @ 13 lbs...but that only makes 390. (400 on the 4.2)

I'd like to surpass that. 400 or so to the wheels should make for a very interesting car -- esp considering this car is actually 100 lbs LIGHTER then my Cobra (I was quite surprised at that...), so 400 should be insane.

As for the 4.6L swap, may not happen solely because...of the transmission. Apparently the N and the S are completely different, trying to find out if they're physically the same (ie can swap internals), cause if not, this thread becomes VERY important to me. ;-)

Hope it works out well. How's the difficulty level on the install so far? Any crazy cramped spaces?

-Matt

Posted by: FreeFaller

Great work Lou! Can't wait to see the final product!

Posted by: fordtechguru

looks good quik.. i have a new respect for you.. excellent pics too, i've been losing sleep about "charging" my 2000 for awhile... super coupe setup looks like the way in.. no room for an ATI procharger up there in front...did you build that all yourself?? it should sound sweet too!!!! get-er-done...

Posted by: Quik LS

update...

- got the oil filler neck redirected
- built the upper rad hose, installed
- dropped the SC and plenums into the manifold

good news - the stock wiring for the IAC valve and TPS fit even though the throttle body is in a total different location....

more to come.

Posted by: beaups

so what's left to do??

Posted by: NickLS

GAS IT UP!! TURN IT ON!! AND VROOOOOM!!!!!

Come on quik.. you know that's what you want to say.. Thats what we want to hear!

Posted by: Quik LS

no - not yet....

- measure and find a belt
- build a lower rad hose
- build some misc clips, hold downs, ...etc
- hook up all the various vacuum lines
- install the new boost gauge
- install new accelerator cables
- build new air take tube
- re-fill the coolant
- load a new tune

Posted by: beaups

what are you doing for fuel? bigger injectors and a program??

Posted by: mdrobnak

Actually, you're pretty far then. Glad to hear you're making progress. It looks great. I'm a little confused on the intake tubing to the S/C though..It looks like it comes from both sides and goes into the back??

Where's the accelerator cable from?

-Matt

PS No word from SCT yet - they're at SEMA, so I can't check what I would like to..

-Matt

PS No word from SCT yet - they're at SEMA, so I can't check what I would like to..

the throttle is on the inlet plenum, that goes in the back intake port of the SC, the compressed air comes out the top, then is routed back into the outlet plenum and down into the intake manifold.

Once I get it going, I'll cut the tubing form the top of the SC to the outlet plenum - the intercooler will go in-line there. I plan to use a standard front-mount and run tubes back up.

the accelerator cable is form a SC T-bird.

Posted by: mdrobnak

Thats an interesting idea (the intercooler) - on my cobra, it's Air/Water with the heat exchanger up front...Is there enough room for all this tubing?

-Matt

First a little background, I was a car audio installer for 15 years and have a EET degree from Devry and a racing background (Karts, Pony Stocks, And Sprint Cars). I currently work for Arrow Speed Warehouse in KC. I couldn't get away from the "need for speed" in my blood. I come from from the land of Pontiac. To be exact, my last car was a 1999 Pontiac Grand Prix V6 3.8 SC. I know you guys are saying V6? Well, now a 12 second V6 Grand Prix is only good enough to get you in the top 50 fastest GPs. You guys can see my last car (My she RIP)here http://www.cardomain.com/ride/294506 . So you can see I'm not new to the Mod Bug. BTW The SRI in the mods is Schmidt Racing Industries (ME). The 13.65 was with only 1.9 rockers, a 3.4" pulley, and a DHP PCM added. Everything else was stock! Not bad from a grocery getter!! I never got a chance to get to the track after my monster mods. Anyway the Grand Prix 3.8 also uses the M90. I know I'm new here and have ALOT of learning to do. So excuse me if I sound stupid in the LS world. I used Digital Horse Power Inc (DHP) for my tuning. Unfortunately they are GM guys. The software is a programmer/editor/scanner called PowrTuner. Its similar to HP Tuners or LS1 edit only far better.

So my 1st question is:

Quik,
Have you done any porting to the SC? I ported my SC inlet to accept my 75.5mm LS1 TB and LS6 MAF. I also ported the outlet. Porting the outlet really helped lower outlet temps and ward off the KR monster. I know you are intercooled but anything helps in that department.

Next, is the Intercooler air to air or air to water?

And Lastly:

I was wondering if anyone in the LS world makes a tuner package for a laptop? The PowrTuner gave us unlimited access to tuning perameters. I could change over 220 different perameters in my tune. It also has a scanner similar to A-Tap so I could also monitor anything I wanted to for tuning.

Sorry for the ramble. I'm just excited to see the SC for the LS!!

Posted by: Quik LS

Yes -
- my Eaton M90 is slightly 'race ported' - Geoff Knight is one of the best in the business. He can do much much more if needed.

one of the reasons we went this direction is that there is an aftermarket of these parts -> http://www.magnumpowers.com/sc_idx.html for example. Quick, easy, cheap bolt-ons for more power.

The callenge is that we can get all the hp the stock internals can handle without too much special.

- I was planning a simple front-mount air-to-air since I'm only running 5psi. Once we get that working, changing the pulley moving up to 8psi and a better intercooling solution 'should' work. We have already worked with Snow Performance http://www.magnumpowers.com/sc_idx.html

- the new Ford PCM currently can only be tuned by the SCT XCalibrator (www.sctflash.com). They sell their software to 'tuners' that then sell their tuning services to you and I - using the XCal to upload the tunes to the car. The XCal has some 'basic' adjustability by the end user. SCT does have a 'Pro Racer Package' that is the same software used by the Tuners, but it is VIN locked to only one car - so you can do all your own tunes.

Hey,
THANKS for answering my post!!
I really look forward to becomming an active member of this site.

Posted by: chr0me

if this all works out good, i will be doing this for a few days... keep me posted

Posted by: Quik LS

Here's this weekend's update:

- finished the upper and lower rad hoses
- finished the vacuum lines (evaporator canister purge line, full load vacuum line, fuel pressure regulator)
- blocked the egr value vacuum
- installed the boost gauge map sensor, boost/vacuum lines, the bypass valve
- installed (modified) the air inlet tubing

What's left:
- measure and find a belt
- accelerator cables
- passenger crankcase vent tube
- installing the boost gauge in the car
- reassemble... all the trim, vents, ...etc
- refill coolant, bleed
- tune
- troubleshoot, troubleshoot, ....

Do you have pics of the intercooler and piping?

Posted by: Quik LS

not yet - the plan is to get it working like this - then add the IC. It's goning to be a standard simple front mount.

Posted by: mdrobnak

Wow that is pretty stealthy with the cover on... (I have mine off, I never really liked it...)

It's a little weird not discharging right into the manifold, like most roots setup, but looks promising. Couldn't we use an air-water like with the 03 Cobras?

-Matt

Posted by: cww102174

WOW..... Quik that is a nice setup.

It the same OE setup Ford used on the 89-95 Ford Thunderbird SC / Mercury Cougar XR7.

The Air-Water would work - but is more $$ and needs more room on the intake.

Posted by: Cruznlife1

have you considered alky instead of a front mount. It will be enough even for the 8 lbs of boost. I ran a powerstroke truck front mount and alky/water injection in my ranger, and it ran 28-30 psi all day long on pump gas.... Blower outlet temps will be lower than my turbo outlet temps too, especially at 8 lbs of boost. When I first got my truck runnig, I was running around at 9 psi non intercooled, I noticed very little difference when I got my front mount in. It was clearly noticeable once I turned the boost up though.... You wouldnt have to worry about piping or anything, I just made a homebrew kit with a mcmaster nozzle, a 12v solonoid, a shurflo pump, some line, a relay and a hobbs switch.... Total cost was under 150 bucks.... I just ran straight $.50 cent wal mart washer fluid and I loved it

Posted by: Quik LS

yep - infact that is the plan once we go up to 8lbs.

Initially we are starting at 5lbs - get it working then start changing up pieces.

Posted by: PGA2B

Quote:

The only problem with that is the washerfluid will strip the Teflon on the Supercharger Rotors

I found that out the hardway in my Grand Prix

. I guess the Cam and the other Mods made up for it though

That is very true. Alchohol is VERY corrosive. But if you're interested in that system, take a look at Snow Performance. They make some amazing kits.

Quik...I've been looking at your pulleys and I'll be damned if I can see how the belt will route. You need to make sure you get quite a bit of wrap around the s/c pulley or it will slip. At 5 lbs of boost, you won't have much problem. But at 8, you could see some slip. One other suggestion I might make. Since I own an 04 Cobra, I'm pretty familiar with this type of power adder. One thing us Terminator owners have discovered is how poor the factory idlers are. There are many Cobra owners who have had the idlers literally explode. I might suggest you give Doug at Billetflow (www.billetflow.com) a call. He makes an incredible set of idlers and it wouldn't surprise me if they wouldn't bolt right up. He has different sizes too...I'm guessing the 92mm ones are what you would want. He has several different colors that are powder coated...they really look slick!! He also has the best damn customer service I have ever seen by anyone anywhere. Give him a call and see what he says!

Posted by: Quik LS

yep - here is the 'planned' routing...

the top pic is the one we drew for the 03+ (same for the pre-03 but add the hydraulic fan wheel)

the bottom pic is the actual stock pre-03

Posted by: Ken Motz

I only wish I was as ambitious as Quick LS. That guys got drawings and all sorts of mechanical aptitude! He'll modify anything!

Posted by: bigern

Hey keep me posted on this i am curious and want to do the same to mine if it works out

Posted by: 2001LS8Sport

NOW I see it! Thanks! One thing Billetflow offers is a 100mm idler for your top idler. It is larger and gives you much more belt wrap around the s/c pulley. Give Doug a call...you won't be disappointed.

Posted by: Quik LS

cool deal - thanx

Posted by: PGA2B

Hey Quik any reason you didn't use a Radix M112 like on the Cobra's? I thought some where I saw a LS with that M112 on it.

My guess is it's more than the car will ever need. Takes more hp to turn, builds more heat (they are Heatons you know!). The M90 is a very capable performer at this level of power.

Posted by: Fastbird

I just got done reading this and I am definitely impressed!!!! That's an outstanding job for being as custom as it is.

One thought: Have you considered ditching the MAF and using the SCT to do a speed density tune instead??? Reason I ask is two fold, being a restriction in the intake and the other being the "what if the MAF craps" which could turn things south in a heartbeat if you're under boost already.

You planning on making this a kit???

right you are. Remember - we only have a 3.9L - most of the GM (GrandPrix, Bonneville, ...etc) all were running 3.8L with an M90.

A simply pulley change and I can add double the hp - but that stock internal will never handle it.

good idea. There are a couple of 'once we get it running' ideas we need to try out:
- intercooler
- moving the IAT to the boost side of the SC
- different injectors
- different tuning ideas - one could be like you mentioned.

MAF crapping out. Possibly, not likely. If it does - guess what the computer does - reverts to a Speed Density tune (Yes, all Fords have speed density backups).

With SCT, the car could be tuned via MAF, then if the car is put through TP / RPM points when everything is corrected, to get the proper load...you could have a Speed Density backup. The ECT/ACT correction won't be quite right, but you'll be in the ballpark.

These damn Heatons really really do build a lot of heat.

Posted by: Quik LS

yep - we are seeing about 12 - 18 degrees per lb of boost - so even at 5lbs it could add another 90 degrees onto the intake charge.

Posted by: 2001LS8Sport

I think that's about right. So on a 90 degree day, you could easily see 180 degree inlet temps. Personally, if you push it hard, without an intercooler, I think you could see temps higher than that. Can you say "detonation"??

Posted by: mdrobnak

96 Mustang GT, Vortech S Trim, no intercooler, 10 lbs boost - I was seeing temps of over 210 degrees at some points on like a 75 degree day.

Intercooling is a must.

-Matt

Posted by: 2001LS8Sport

And the Eaton will give you even higher temps. I agree...intercooling is a high priority. Of course, 5 lbs of boost won't be as bad....

Very important point here. If the car is putting more timing into the spark because it thinks that ambient temps are actual inlet temps then very bad things could possibly arise, especially with the fine line that will be walked anyways (high comp non-forged engine + heaton). Roots on an LS isnt a bad setup at all, but it can be made as safe as possible if the IAT is placed after the charger and intercooler too. One less thing that could cause problems.

Posted by: mdrobnak

Of course. IAT must be relocated to after the supercharger / supercharger + intercooler.
-Matt

Posted by: PGA2B

Correct me if I am wrong but if you put it after the SC won't it see temps above 100? Like 150-300? I know on my GP I would see temps 275-350 coming out of the SC at the lower intake manifold before I Intercooled it. The air to water Intercooler dropped temps 130 to 150 degrees and with all my mods allowed me to run a 2.6" pulley with 22* timing and 0* KR on 91 octane in the summer in KC.

Also--Quik, is the shaft of the M90 T-Bird SC the same size as a M90 for the Grand Prix? If so I can get a modular pulley setup.

right - that's why it goes in the outlet plenum after the SC and after the intercooler - so it reads the actual temp going into the manifold

Oh yeah I forgot this car is NOT designed for a SC. So the PCM is not written for this to make calculations. I assume that the GP is designed to "see" a certain temp and adjust the fueling and incoming air. The IAT is in the stock throttle body that is bolted to the SC. Since I had an LS1 throttle body (NO built in MAF) I used the IAT in the LS6 MAF (Built in MAF). But then again its designed to compensate for the IAT before the SC. So what kind of temps are you expceting to see for IAT readings?

BTW-What are you using for a MAP sensor?

I would guess a parts list is forth coming once the project is complete?

I still have some MAF and other tables if you think they would help. I don't know if my tuning experiences could help or not but I would think they would somehow. The rest of my tunes would do you no good because you have to have a powrtuner to read them.

You might want to contact a friend of mine about tuning. Considering he wrote the Powrtuner program

Hit me with a PM I would LOVE to talk to you about this.

That is why factory supercharged cars like the 03-04 Cobra's, for example, have two IAT's; one before the charger and one after the charger and intercooler. The first to read ambient temps and the second to read actual temps. I dont know allot about the GP's but I would venture to say that there just might be another IAT hiding somewhere under there.

They only have the one IAT before the SC.

I don't think they do - I believe the blower outlet port is directly on the top of the intake manifold.

many of these low boost applications simply routed the throttle body to the intake port of the SC, and then bolted the outlet port to the manifold. simple, clean - but cannot handle high boost levels without adding intercooling.

Before I intercooled mine I was running 13psi and after the Intercooler I dropped from a 3.0" to a 2.6" with 0kr and 16psi.

And then whether the manufacturer chose to IC it or not determines whether or not the aircharge goes into an IC or goes into a collection area inside the manifold and then distributes out to each port in the heads. Either way, there is an area to put an IATS in both applications. Heatsoak on a hot day and just a tad little bit of bad gas can blow engines, with no IATS after the charged air, sky-high. When the Kenne Bell goes on my truck I will be relocating the IATS after the charger for sure!

Belive or not GM used timing retard and torque reduction to control KR. The knock sensors serve two purposes in these cars. 1. To sense knock. and 2. to predict knock. Gm used the knock sensors and torque abuse to control KR.

From the factory these cars see KR!! Up to 5* of it.

Posted by: 2001LS8Sport

Talk about two different methods of controlling things from two different manufacturers! My Cobra doesn't even HAVE a knock sensor! NADA...Nothing!! There are guys pushing 20 lbs of boost out of the Eaton without a knock sensor. It just goes to show what proper programming can do for you.

Quick update from this weekend:

- added a third pod for the A-Pillar cluster
- wired and installed the boost guage
- fabbed up a modification to the stock T-Bird accelerator cable mounting bracket - and believe it or not - the stock LS accelerator cable fits prefectly...!
- put the car back together and charged up the battery

Last thing I am waiting on is a new sepentine belt. I need a 6 groove 129inch - 133inch belt (very long).

Posted by: mdrobnak

Awesome! Can't wait to see it when it's done. Are you going to get some video of the first start?

-Matt

Posted by: FreeFaller

Out of sheer curiosity Lou...why did you choose the TB SC over a centrifugal type SC. Also is the SC you are using a roots or a screw?

Posted by: Quik LS

It a Eaton M90 - so a roots with a 60 degree twist.

Choose the T-Bird setup since there is an aftermarket for it - can get parts and can upgrade components as needed (or wanted) - like TB, plenums, ...

The drivability of a roots is better, the cost of the part should be lower, and I was concerned about rom under the hood. So far - seems like the right choices - but until we get it on the road....

Posted by: FreeFaller

Thanks...I was just curious.

Posted by: Cruznlife1

will you ever decide to sell someting like this as a kit ?

Posted by: Quik LS

that is the intention. make it a kit - of different options - all the pieces, w/o SC, w/o plenums, ... etc

so people can plug and play with costs and other components.

Posted by: Cruznlife1

well I still have a ton of parts from my old turbo ranger here (tig, boost piping, couplers, clamps, ton of other

) I also have some supercoupe stuff here, have 2 m90's, some throttle bodies, and some other things. the biggest thing I'm worried about with something like this is the intake manifold fabrication. I'm looking for a low boost setup, non-intercooled with water injection.

Dude, when I am doing a custom supercharger project I usually just go out to the local O'reilly's store after taking some quick string measurments and then buy about 5 belts within that range in .5" increments. Then I take and fit them from smallest and so on till I find the one that fits perfectly so that th etensioner is in the right place while keeping things taught. Then I take the rest of them back to O'reilly's with the receipt and still brand new and get the rest of my money back. Good luck man, it will be killer. I just got my 05 LS today finally, so I can start taking prelim measurements for the custom centri project for this next summer. Take it easy man, looking good and fun!

wow - I never thought of that....

of course that is what I did. the string measured 133inches. the tensoner moves about 2.5inches - so I have the play of about 5inches so I need a belt about 128 to 133 inches - so I need a belt about 130inches

sorry - but auto belts go up to about 122inches, industrial best start at 136inches....

I found a Dayco at 127inches - so I'm gonna try it.

If you can help - please help find the belt.

You're barking up the wrong tree here. You completely misinterpreted Quik's response. I have NEVER seen him throw "a fit" on this site. As a matter of fact, he is probably the most helpful single individual you will find here...and the most innovative. If you want to alienate yourself here, make another comment like that.

Well said... Quik and I settled any misunderstanding or minor quarrel we had so those of you still crying about it, just stop perpetuating it and move on. This thread is not about this.

Posted by: PM80

Ok i need an update it has been too long? Do we have any numbers yet.

Posted by: Quik LS

not yet - still waiting on a belt.... ;(

we really do not want to change the belt routing we've made as it fits both the 00-02 and the 03+ V8s - and the new belt for the 03 V8 is easy to get. Geoff Knight is help me now to work through the various vendors....

I have the update tune file to start with - and then will use datalogger to provide feedback to the tuner to improve the tune.

I have a Innovate Motorsports LC-1 Lambda cable and wideband sensor to do the a/f.

.... so hopefully a belt away from starting it up - then troubleshooting....

Posted by: Fastbird

When it's done and you're ready to mass produce them......I want one. I'm getting ready to throw an ATI D-1SC on my 93 Trans Am and thought: How cool would it be to have TWO blown cars in the household!!!!

Btw, going to datalog right now ;-)

Posted by: jokken

just a thought for the belt. if you can't find the correct one maybe find contacts at the companies that actually make the belts. maybe they can make you a custom belt. I had a few times (not with belts) where the manufacturers made me a custom item. They hope to get return on it if it becomes a popular need. one electronic company made me a specific multi-throw, multi-poll switch for free and even shipped it for free, they billed it internally as a "prototype".

as matter of fact if you want give some specifics I'll find some email addresses and send some emails too.

Posted by: Quik LS

Well it looks like Geoff Knight was able to locate some options with his contact within Gates - so he has both a 130" and 132.5" belts coming to him - then to me to try.

They are willing to do a custom job - minimum order is 50 - so like to avoid that if I can.

Here are the measurements:
- with tensioner fully un-loaded - 133inches
- with tensioner loaded to correct placement - 130.5inches

6rib - but will split 7 or 8....

Posted by: PGA2B

TTT

Posted by: Quik LS

good news - got a belt - it's a Ford stocked belt for a truck 132.44" 8 ribs. I cut it down to 6 ribs and spent 2 hours getting it on - fits perfectly and the tensioner is in the stock loaded location.

I filled the coolant up and charged the battery. Then uploaded a new tune from torrie into the car.

I then started it....................

and it ran for about 5mins - sounds very serious.

but I shut it down when I notice a leak on one of the injectors - at the rail.

so I have a 'little' work to do......

I probably pinched an o-ring or just have it a bit off on the mount....

very close...(I hope)!

Posted by: beaups

looking good. quick how much clearance is there to the lower right where the belt almost touches itself off the dummy pulley? looks in the pick like its nearly rubbing.

Posted by: Quik LS

yep - it's close (1/4") but everything clears - I'm amazed. At least I have good wrap on the SC pulley

I'm sure there's more troubleshooting after I fix the leaky injector....

Posted by: beaups

Honestly I don't claim to be an expert by any means, and would never attempt half the stuff you do...but that sure seams like quite a wrap around the SC pulley. Are you concerned about damage or the belt coming apart at high RPM's? just wondering

Posted by: xcadia

@ quick
Do you have a intake designed for this setup?

I assume since you have a scoop you are going to try route it back to there.

If you have it designed can you post some pics?

Or can you post sketches of what you have intended;

Posted by: waltdeuce

Hey Quik, got a question. How similar are the engines on the LS and the Jaguar S-type (V8s)? Would the supercharger from the S-type fit on the LS? Would it be a more expensive task than the one that you've done?

Posted by: Quik LS

not very similar at all. I posted a tread about all the components shared between the two - you should be able to find it.

only the block are the same. the head, stoke (hence 4.0L vs 3.9L) and PCM are all very different.

the McLaren LS used a similar setup - very expensive to build (like $7k in parts). The first post in this thread is from the auction of that setup for the LS (similar to the S-Type R).....

I'm looking to build about as much power on half the $$$ - and half an aftermarket of parts to build more with.

Posted by: waltdeuce

What's your estimate on the amount of horses you'll be adding? I'll be waiting for your results. Patent that baby asap so we can start buying.

Posted by: Quik LS

should be about 80 - 100hp from stock. Not sure from where I am since I'm already 'a little over stock'....

trying to keep with stock injectors and stock fuel pump - then will go up on the injectors...

only stock internals.

Posted by: SilverLS

I know Im waiting in Line for the V6!!! I cant wait .....

Posted by: Quik LS

Here's this weekend's update:

So you know I started the car for the first time last weekend - and found a leaky injector.

So this weekend - I tried several things to re-seat the injector without having to tear too many things apart - no luck.

So I finally dug back into it - I was lucky to only have to remove the SC top and downpipe plenum and was able to get to the fuel rail. It took a couple of hours as all the work is in very tight spaces.

I was able to remove the leaky injector and did find the nicked o-ring!!!

So now - buy new o-rings, reassemble, re-try..... ah for another day.

like your setup have you given anythought to inverting it as ive done for the tbird sc also if you do you can put a small water to air ic under it taking the room that was used for the blower top thus staying under the hood.

Just curious...are you able to say when, if at all, your prototype will be up for public sale? As most are I am very excited and very impressed with your progress. I read something about the sc being half the cost of the mclaren (about $3500). Is this the rough price you would charge? Thanks in advance.

Posted by: bronco_ls

I was woundring, since the 3.9L V8 that we all love so much ing our LS's is the AJ-V8 Jaguar motor. It is for all intents and purposeses identical "http://en.wikipedia.org/wiki/Jaguar_AJ-V8_engine" to the Motor that Jag puts in the XKR, Landrover, Austin Martian... and puts a supercharger on it in may of these auto's. Both the 3.9 and 4.2 are built on the same block and both have a 86MM bore, the only diff is the 4.2 has a 90.2MM stoke VS. a 85MM in the the 3.9L.

SO when adding a a supercharger to the LS why not look at using the parts that Jaguar uses when making the XKR such a beast.

OR

Am I just being stupid and just not noticing that the Jaguar SC is in fact a EATON M searies charger like Ford has been using on the motors for years.

SD

Posted by: Quik LS

nope - not a stupid question - it's asked a lot.

The McLaren LS tried to use the exact same setup - and so does the S-Type R. the parts alone are over $7k. not including all the same issues of routing vacuum lines, cables, electrical, throttle, ...etc - since the Jags do not use anything else similar (other than the block).

The first post in this thread is from someone who purchased a 'jag' setup.

If fact - it was sold on e-bay by the same guy (Geoff Knight) who is helping make mine. The parts are just too costly to make it a kit.

Posted by: bronco_ls

Thanks alot for the quick answer. I just got my first LS and I am trying to lear my way around it.

Posted by: Quik LS

Here's an update:
Tore some part up to get to the fuel rail, replaced the leaking injector o-ring...

so the fuel leak is fixed

put everything back together.

The car is running, rough and stumbley.... at idle, give it some throttle - yikes! Sounds mean....

So now I have to check for vacuum leaks and ensure I'm getting the proper amount of vacuum at idle.

more this weekend.

Yea, but the car never ran right. It pinged like crazy. They kept blaming that on the last guy that filled it using regular gas. AFAIK, they still haven't got the thing running right. Something about the pcm.......

that is not a difference for the hoursepower gain - since we are both running very low boost - not nearly what the M90 or M112 can really produce. I suspect they went to an M112 to get a larger output port footprint - since their prototype is mounted to blow directly into the manifold, they wanted to make sure they would get equal pressure across all the ports and needed a larger SC with a larger base output port.

Hey Quik whats the update bud. Its been a few months now. I hope work isn't pulling you away from the car often enough to cause you to delay finishing it up this long!

Posted by: Quik LS

Sorry guys - I haven't been checking this thread....

I have the car running - un-tuned.

I am now swapping out the stock injectors.

The LS uses a Delphi FJ10533 injector - crazy 'air assisted' design - that the stock intake manifold has an 'air-rail' half way up the injector bung. There is a line from the intake to the air rail. The idea is that each time the injector fires it mix some additional air into the mix providing better atomization of the spray.

The manifold we made does not use the air rail - so I'll dump the air assisted injectors since all it will do is cause a huge vacuum leak for me.

I am going to try to take Friday off - and put a couple of days into the car.

Shouldn't be too bad to tune. You might not have to worry as much as your thinking with the air assisted injectors. They are pulling already metered air from the intake before the charger but after the MAS so its air already accounted for. All it is doing is giving it extra time to mix. You might not be as far off the tuning mark as you originally thought with the air/fuel pre-mix setup swap. As you already know dynotuning with a wideband will be the best/only way to dial it all back in perfect.

You aren't kidding bro. Best thing that some of these chip/flasher manufacturers could have done (new gen predator/ SCT Xcal2).

The LC-1 is a great meter, especially when you factor in price. I was looking at a few others, but the LC-1 combined with the Xcal2 does everything I need it to do without all the extra crap. Great price!

I will also be receiving my PRP here soon too so that should be fun to explore Advantage 3.0. It will sure be nice to be able to tune my own car from the ground up without having to rely upon someone else for any kind of assistance (aka waiting 3 weeks for a tune that works ok).

Take care and I hope to see a video of that thing soon. Hopefully by next week I will be able to post a video of the Kenne Bell Explorer finally tuned. I am really looking forward to seeing a video of your LS doing a nice long smokey staging burnout. Should be quite a show.

Quik...what injector are you using? On our Cobras, we usually go to a 60 lb injector (39 lb is stock) but we have to use harness adapters to make them fit the factory harness. I'm wondering if the 39 lb injector would fit the LS harness? If so, there are a ton of those around cheap and they would be plenty for your application.

Good point 2001ls8sport, I would think it should be the same clip. Just like the picture above. You know whats the funny thing, I didn't notice any air assist crap when taking a look at my injectors on the 05. It must have been something they changed when going to the 03's.
