Anybody modified the CAI from the butterflies all the way out to the box in the fender? I'm looking for this mod and want to know HP and torque gains. I tried to get a guy on the site to make up this set up, but he blew me off.
 
I would say that with the stock intake and tb you will see minimal gains on a good day with a CAI... You are really stuck withteh stock tube unless you are a good sheet metal fabricator and could make something better...

I would put intake as a mod very low on my list, just not worth it.
 
And its a pretty known fact that these cars breathe great, its the exhaust that needs work.
 
Gen1 or Gen2?

This is my Gen1 CAI setup...

God i've heard that too much. But hey, if i didn't know i would've spent money on something i dont really need. It might give a little sumtin sumtin but not worth the $ if you go the lms route.

As far as exhaust i agree. Hell, 3 cats?

I just want a CAI in order to get rid of that god forsaken stock air box..

The cheapest route I went is with a Cobra intake setup. Where the cone rests there are two openings. One on the side (fender) and one below that pull air from where the silencer is.

Its not air tight, but could be made to be. Although really the factory box is CIA sorta. If you want to wrap the tube, thats another story.

the other thing to do is get a piece of flexible duct and cut a hole beneath where the stock air filter box was and run a k&n style filter behind the bumber cover where it can pull air from the cut out. simmilar to the mustang set up.

as long as he air compressor(s) arnt n the way.
also have to note how unity keeps putting up pics for me...................:rolleyes:
 
A question that I have is (as I use to have my cone filter in the fender well)

What about turbulence from the air coming up the 90 degree bend would that cause any trouble or loss of power?

Currently I have my cone filter behind a cold air shield. I've been working on making an air damn that would channel more cold air into the filter compartment. I took the old silencer that mounted below the air box and then cut off the baffle and the intake tube and fashioned a scoop. I haven’t installed it yet but it should force cold air from the fender into the filter compartment.
 
The only negative I see from the 90 degree set up with the filter behind the bumper is that its not ideal to have bends before or after the MAF.
 
Cold air rules

OK, next half of this debate- i had a street/strip car that I added a scoop to the hood and sealed an open air cleaner to the undeside of the hood at the scoop with foam- it dropped 3/10's in the quarter. So- now we're talking CAI plus ram air effect. Speculation on the results?

Dammit driller you beat me to it.

Kevin, hit up Jamie for a junk hood that you can hack up and play with. If the results turn out favorable, then you can make it look pretty, otherwise you haven't gone and ruined something nice. I'd bet you won't have much to gain, though.

Where did you get the heatshield? Did you fab that up? Also the metal intake piping, does that attatch directly to the mafs? Or is there a cone adapter underneath that?

I would like to have a similar setup so i dont have the whole home depot thing going on, but i think it works pretty well. im embarassed to take a picture.

mafs - mafs cone filter adatper, rubber sleeve, PVC 4" (PVC going over mafs adapter) elbow to 3" to a 9" Spectre filter in the fender.

I think it was Mespock who had a similar setup, but he used a rubber elbow, couldn't find that at my local home depot!

LOL, it would work beastly on a carb setup with the right jets. But on an EFI I bet it would be barely any difference.

Years ago a company named DenseCharger manufactured CAI kits for 'Stangs, Tbirds and the likes. I bought a complete setup after talking to the owner. It's basically a hybrid between a Cobra and Tbird kit. The Cobra kit exited out the side of the fender and had another 90 degree elbow with the filter inside the fender. The T-bird setup exited out the bottom of the fender. The Pro-M MAF was calibrated for the 96-98 Cobra 4.6L and the second elbow was deleted from the kit and I think the MAF adapter was from the Tbird kit. The elbow and filter extension are PVC. The PVC elbow is flanged directly to the MAF. The other end of the MAF is directly connected to the stock rubber bellows type tube connector that used to connect to the stock filter box. The hole in the fender for the piping had to be enlarged - likely the hardest part of it all. Also this setup requires the suspension compressor to be lowered 1-1/2" to make room for the air filter.

Armed with the calibration numbers from the MAF, the tune on the chip was made to match, elbow and all. While one could argue the HP benefit of the MAF and all that, the CAI is very efficient. I moved the outside air temp sensor to the fenderwell right next to the intake filter and can monitor intake temps real time.

The heatshield was an original IceBox from LMS. I had to notch it to mate with the new plumbing. It helps shield the setup somewhat. The intake tube is simply wrapped in heat reflective material - ricer style. :D
 
Hey guys!

This question seems to come up a lot on here. Why don't we make a sticky concerning basic modifications and call it like proven performance mods or something. It could have basic exhaust modifications, a comparison of K&N panel filter to a hot air intake to a well built, dyno tuned custom intake, gears, converter, tuning, so on and so forth.
 
You can't really put together a well done comparison of mods when you have a bunch of different peoples cars... not every car will respond the same.

I can tell you what the three most effective mods on a Mark are in this order:

Tune
Gears+Tlock
Torque Converter
 
you say tune is #1 mod, what do you recommend? I'm pretty novice with this computer stuff, do you recommend a chip or getting it hooked up to a laptop somewhere??
 
The 93-95 cars are in a "rough spot" for the DIY tuner, since there is no cheap solution for datalogging like there is for the 96-98 cars (obd2)

Since you cannot effectively datalog an eec 4 car it makes it very hard to fine tune a calibration.

There is tweecer (www.tweecer.com) that will datalog an eec4 car.. only drawback is your paying 650 dollars for a datalogging solution.

The best bang for the buck, would be to get a tune from a known and trusted vendor such as Lonnie At Blue Oval Chips, he can put together a very good tune for you, based on his extensive experience with these cars.

If you had an obd2 car I'd just say get an Xcal 2 and the PRP pacakage and "tune it yourself".. but. I had a very very long hard fought battle tuning my eec 4 car with no datalogging solution, it took literally 2 years and over 2000 dragstrip passes to get it "dialed in".

Then once I got an obd2 car, and could datalog it. I saw exactly how much performance AND economy that my first tune had left on the table.

I've got a rock solid 93-95 tune for the first gen mark 8, and I'm just now putting the finishing touches on my 98LSC tune.. the datalogging sure was an "eye opener".

SCT is by far the best tuning solution out there, I only wish they had released the "datalogging chip" they advertised about 5 years ago.. it's a shame it never made it to production.. as it left a HUGE GAP in the Mark 8 tuning world.
 
Cai

The car I was referring to was a '69 Cougar XR7 with a 351W, Edelbrock Streetmaster, 650 Holley modified with secondary jet block in place of the plate so we could change jets and the opening rate, lighter springs in the secondaries, headers, Mallory ingnition, comp cams 280 kit, shift kit, etc.
Wish I'd never sold the car.
