beat me to it

I am just talking about me and a buddy's exp. We both bought a c&l and on one end we both had to grind the housing for it too fit. We probably could have sent it back but we bought it from a vendor at a nmra event and did not want to wait. It was our fault for not looking them over good when we bought them but we were to interested in getting back to the races.

c&l are junk on foxes, i have heard they work good on SN's though. I had one, and couldnt get the idle right to save my life, put a pro m on, and it was perfect. As for a power increase dont expect much, the stock intake really isnt holding you back, its teh heads that do the damage. I also agree with 13, that TB is too big for those mods.

OK, this tread is going to carry a lot of assumptions simply because we don't know what your stock rwhp is, older cars tend to vary, much more, than new cars, for obvious reasons, when calculating rwhp due to the different wears indured by the car over time.

Based off of dynos I've seen of totally stock 87-93 Mustangs, I'm gonna say that you have around 170 rwhp. Now with that said, he's what I'm "guessing" you'll gain.

Also, as stated, they do no make a 76mm throttle body, but in any sense, unless you're touching the heads/cam, there is absolutly "NO NEED" to go any higher than 65mm. There is a fine line with air intake, too large of an opening can be just as bad as too small of an air opening when the wrong application is applied.

O/R H Pipe W/ Flowmasters - 8 rwhp
CAI - 6 rwhp
65mm TB - 3 rwhp
Cobra Intake Upper/Lower - 12 rwhp (guessing here, probably way under, but it's better to be under than exaggerate anyday)
MAF (bennifit of a doubt) - 2 rwhp
Total - 201 rwhp

Now those numbers are rather restricted guesses as the Cobra intake can be very iffy. In short, on a stock engine, the Cobra, Trick Flow Street Heat, and Eddelbrock, will all yield similar rwhp, it's the heads that make the difference.

there is a 91 gt for sale here local, he posted his dyno and it was 199rwhp with full exhaust and bbk cai.Also was on you tube watching some dyno pulls, saw a gt put down 205 with just a K&N and a catback.. if your car isn't running with a bunch of messed up sensors, and your ignition/fuel systems are in good shape, no reason you shouldn't be around 200 pre your intake mods.. and I've got to think adding the bigger maf/tb/intake has to be good for another 20 horse or so but speculation sucks, if I was installing all those parts at the same time I'd definetly shell out the extra 100 bucks or so to do a before and after dyno run.

TB Is a 65mm

don't expect more than 7-10 hp

stock intake is good for 300 hp actually, as well as the fuel and rest of the induction

the heads are the holdup like stated b4, you'd be better off just putting gt40 irons on and keeping the rest stock for the same price as a cobra intake

you won't see any noticible gain, and i speak from experience not speculation

on my '90 GT i scored a ported "real" gt40 intake for a giveaway price and just threw it on since i had it......ZERO change in ET or MPH

on the other hand, i was pushing 300 hp on my '89 notch, stock block, boltons, 4.10's and nitrous , it went 12.50's at 108 , all stock fuel,induction etc.

i'd cancel and save for heads personally

agreed, the heads you have on there, are defective.
