Good stuff. I am glad to see another person on here that actually does a little wrenching on their vehicles. ;) As a gearhead and performance shop owner I must mention that if you want to hit 10's in a V6 LS while keeping it streetable and I assume non-gutted interior then you have a little bit of a hill to climb. Relatively speaking, it is easy to drop a Mustang into the 10 second zone if you just gut it, throw a big engine and a blower or shot of nitrous on it and so on. Heck, you can do a Fox Mustang into the 10's for dirt cheap on a budget build. It gets trickier when you do not have the luxury of throwing it all out and starting fresh or buildinng off an already established platform. As you know the Mustangs have a much much larger aftermarket than the LS does. That means custom fabrication and lots of it for anything and everything you do. I tend to specialize in building sleeper vehicles and it is a totally different ballgame then building a full on drag car; with the sleeper being much more difficult.

What are your plans for the LS then? Keeping the V6 and building the bottom end? What transmission? Keeping IRS or swapping to custom 4 link solid rear?

What class in NMRA do you race in? Good to see another Mustanger and gearhead around here.

Exactly... It's too easy to make a mustang go fast now a days. LOL
I wanted a challenge. LOL

There is going to be a lot of custom fab work done. I plan on working with Pro Power out of Fort Lauderdale, Fl. to get the items needed to build a strong enough bottom end to hold some good amount of boost. Ronnie Wilson of Specialties machining will be assembling the motor. Blow By Racing has done some awesome stuff with CNC porting and polishing of cylinder heads as well as doing custom regrinding of camshafts. So I'll be working a lot with them with the heads and cam work as well as the tuning of the car. I'm going to keep all the luxuries the car offers but I will also be having a 6 pt. cage installed in it by race car builders in Palm City, Fl. As for the transmission, I am not sure yet what I'm going to be going with. I want something streetable. That is my Number1 thing. I know it'll be a little more jerky, but I don't want to put in a C4 or anything like that. I think I'm going to keep the IRS in the car, but I will be making up some custom IRS braces and other strenghting items for the rear. I wont be running Slicks on the car, so wheel spin will be needed. Probably just a BFG Drag Radial. I'll take minor weight out of the car... Like I said... Lots of custom work, LOTS of TIME... and of course this is probably the reason I'm single. LOL


I run in the NMRA Factory Stock Class. It's not the fastest class, but it is a highly competitive class. To get an ALL MOTOR 281cid 2 Valve Convertible Mustang into the 11.30 @ 118 range is respectable I think.
 
What plugs do you use with nitrous?

I contacted NGK, and after many emails back and forth, they had this recommendation. The dyno man also recommended the NGK Iridium IX.

"Brock for the 100 shot I would suggest going one heat range colder and
to also close the gap about .005-.007"" to about .037-.039". So you
would want the BKR6EIX-11 stock# 3764. Typically with one heat range
colder plugs and even two heat range colder plugs you will not be able
to notice a difference on a fuel injected engine."

NGK did not have a plug that crossed over to copper and also dropped 2 heat ranges from stock. I ended up going with Champion plugs. I forget what part # they are but just take the stocker plugs, cross over to copper instead of iridium or platinum and then drop 2 heat ranges from there and that will be your proper nitrous plug. I did close the gap also. I want to say I gapped em at .035". Made good power, no spark blowout and things ran well.
 
Wonder if one heat range instead of two has anything to do with the dry versus wet system?

Nope. Regardless of dry vs wet you will still be looking at the same A/F's to shoot for. I suggest an 11.5:1 AFR in a car of your weight while on the nitrous to be safe.
 
"11.5:1 AFR"

Yes, I have used 60 so far, but have an appointment with the dyno for three runs to be sure about 80, and 100. $80 will be well worth it to my peace of mind. Thanks.

"cross over to copper instead of iridium or platinum and then drop 2 heat ranges from there and that will be your proper nitrous plug."

I assume what you are stating is that copper should be used, two ranges colder versus iridium and one range colder. If this is the case, then I need to determine why this conflicts with the recommendation of NGK, and my dyno man. They both specifically recommend the NGK Iridium IX in a nitrous application. I'm just trying to make the best choice. Thanks.


"Brock,

The iridium IX series work very well with nitrous and is what I suggest
whenever possible. The iridium center electrode has a much higher
melting and oxidation point over standard nickel alloy which helps it to
hold up much better to nitrous use. The special taper cut nickel ground
electrode also helps the flame kernel to expand faster and grow larger,
being able to burn more fuel and increasing ignitability. Hope this
helps clear things up. Thank you."

Installed NGK Iridium IX plugs today, and the Motorcraft AGSP32F plugs that came out are stamped NGK which surprised me.

Brock the problem lies in that NGK doesn't know crap about how and why nitrous oxide works; especially how to make nitrous work safely in a daily driver vehicle. A few reps may have an idea, but probably not as full a perspective as what is needed to give sound advice. The plats and iri plugs will last longer than coppers but the coppers will be safer with less detonation. You will go through more plug changes with the coppers but run a higher chance of detonation. NGK does not take that into factor which is why they say what they said. As for your dyno operator? Hehehe. I have ran into mannnnny monkeys who also could operate a dyno and trust me just because they run a dyno does not mean they know how to setup a vehicle for nitrous in the best manner on a daily driven vehicle. I actually had to teach one dyno operator how to operate certain functions on their dyno because it was taking too long for him to figure it out on his own. He was not a new guy either. Yeah, it is best to not take advice from those guys as allot do not know how or what to take into account for a proper setup.

Like I said, from the stocker plugs you will want to drop 2 heat ranges then cross over to copper. NGK does not support that particular plug which is why I went with Champions. You could run 1 heat range cooler and probably be ok, but I suggest you drop a full 2 ranges to keep things a little safer. With these cars it is best to not get greedy.
 
"NGK Iridium IX plugs"

They are already in and one heat range colder. I'll let you know the results of the three dyno runs which will be done with the SCT Xcal3 nitrous custom tune installed by Torrie. Thanks.

Do what you want. Like I said, you will probably be just fine, but it will not be as safe for your engine.

Just for clarification, I meant that the coppers will require more changes but you run a higher chance of detonation with the NGK iri's.




You are doing a dry nitrous system on your LS? You are not going to enjoy having to swap tunes for the nitrous constantly. That is one of the bigger reasons why I went with wet on the LS was due to the time it takes to swap tunes in these vehicles. I hope you are doing something with your fuel system, namely the injectors, to ensure proper fueling. Torrie can increase your delta fuel pressure to make your injectors act bigger but then it will in turn put allot more strain on your fuel pump, which will already be at a somewhat higher duty cycle with supplying enough fuel for the 100 shot alone.

My new engine will be running a set of MSD prototype coils developed for the four-cam Mustang. I surely agree with 2 ranges and copper. I am NOT a fan of Champion. Does anyone know of another source?

What is your reasoning why you are not a fan of Champion? I am not neccessarily trying to defend anything here, but I am curious as to your reasoning. I have encountered others that said that but when asked why in particular they could not come up with anything other than "I heard they suck" or "they just make your car run like crap"...

In my personal experience I have been using them for 1.5 years and they have performed flawlessly.
 
Negative on Champion Plugs

Back in the mid '60s I was part of a consortium running a Ford Fairlane Thunderbolt. Since it was a factory racer, we had support from a wide variety of sources. The 427 High Riser was very hard on plugs. We had to change Champions after every 1/4 mile pass. Since we were given plugs by the case, there was NO expense involved. However, the work necessary by DST to put the engine in made it very difficult to reach the plugs and I still have faint burn scars from coming in contact with the headers, even after all these years.

Autolite plugs would last for several runs---often a whole day's racing---before needing changing. I lost all fondness for Champions from this experience.

Ken, you do realize that you are making a statement in present day based upon findings you made roughly 40 years ago. Though your perspective is understandable due to your past experiences it is just a little outdated.

Anyone who is in touch with things in the performance world knows that it has taken much less than 40 years to see the rise of a great product with a company under the correct supervision. Then fast forward only to see that same "great product's" demise a few years later due to various problems with the company and its leadership. What I mean by this is that opinions on manufacturers have a shelf life and it probably isn't 40 years. That shelf life is dependent on what the future holds for each and every one of those companies. Heck, look at VT Engines they are a PERFECT example! For those who do not know, VT Engines was THE PREMIERE modular engine builder in the country for the past few years bar none. There are some other real good ones too but none really could compare to VT. Their product and services offered was top notch and their costs did reflect that. As of earlier this year there was a restructure in the company and new ownership came in. In a short time that company, and its new sister company, went to the dogs and their product and all its quality went with it. That immense change took less than a year to happen. You take time to blink in this business and things will surely pass you by.
 
Plug Question

My prejudices are just that---prejudices. It wouldn't, of course, be fair to say that there's been no improvement in plugs in the last forty years. On one hand, I was using triple-ground-electrode Auburn plugs in my '34 five-window with '53 flathead back in 1959. On the other hand, the advances in plug design and construction are the features usually listed as undesirable in boosted engines. Hence my question.:)

I would hope that some advances in quality control would have taken place in that timeframe as well.
 
how in the world did your power curve make a loop...seriously, someone explain this...there is a loop in the dyno graph...wtf?...boggled...
