    how much gain?

    I had stock headers, mac o/r H-pipe, flowmaster 2 chambers, and dumps. It sounded like an old car. Very loud and obnoxious. I found that it did add a little power up top end and it lost a little torque on the bottom. Not a big difference in power though. I found a good sound is the Mac H-pipe...

    Car dies randomly at idle

    Your car obviously has different parameters in the CPU when running hot rather than cold. For one, you can run your fan earlier (keep cooler). I totally forgot that you can run Tweecer when the car is running. You might get the car to die at idle while tweecer is logging. That would be your best...

    Eibach Help....

    Check Eibach's website. If they give two different part numbers for both Convt. and coupe then I would not use them. There would be a reason for the two part numbers. If there wasnt a reason then Eibach would have only made one number (cheaper for them).

    How Much Power?

    I am looking for right around 300 RWHP/RWTQ. Can I get this with K&N, X-pipe, and Cat-back, or do I need to add other things like chip and pulleys? Don't really care for the chip and pulleys though (bad experience :( ). Also roughly how much do headers add (HP wise). It seems to me that they are...

    Car dies randomly at idle

    If you end up changing your TPS, there are two different part numbers available. Just keep your stock TPS handy for the part # (just in case). But I don't think that will solve your problems. 94-95 mustangs do not respond well at all to any engine mods. Just find a local programmer and ask him...

    How Much Power?

    Would the K&N be more effective if I had exhaust on the car?

    Car dies randomly at idle

    I still think a tune on the CPU is needed. The stock Ford CPU has problems with it from the factory. It is not too expensive to have a custom chip burned.

    Car dies randomly at idle

    I would let a professional do the tune on your car. I had the exact same problem on my 1995. Runs and idles fine when cold, but when started hot car runs like crap and the idle dies often. I also used to get a lot of pinging. I must have changed almost every sensor on that thing and still...

    Car dies randomly at idle

    I had the same problems with my 95 GTS. I think this is a pretty common problem with 94-95 mustang GT's. Having a custom chip burned will help a lot with the idle problems, if there is nothing else wrong with the car.

    cobra intake

    No it will not. You either need the stock Cobra strut bar or an aftermarket bar. Most aftermarket bars will clear the cobra intake.

    How Much Power?

    Quickie, around how much RWHP does the K&N FIPK add to a 01 Cobra. I know it all depends, but does anybody possibly have a dyno graph with the only mod being the K&N FIPK. Not the chart from K&N either, they exaggerate their numbers. Thanks

    Aaaahhhhh!!! I Have A Big Problem With The Cobra

    There is a big noise difference between a rod knock and a collapsed lifter noise. If you are hearing a actual knock you will know it. A ticking coming from the engine could be a number of things. One question I would have to ask is, how many miles are on the engine and (honestly) how hard do you...

    Royal Purple or Mobil 1

    It works out perfect at Costco. They sell 6 qts. for $24.99. You can also pick up dinner and your photos all in one trip. :nice:

    Would 3 inch Exhaust Hurt my car?

    I get blown all the time. So I guess I should go with the 3 inch. :D J/K. Its just that the 2 1/2 inch kits are much more expensive (Bassani, Magnaflow). Well I guess they are worth the extra pennies.

    Would 3 inch Exhaust Hurt my car?

    Any reason why? Or just because.

    Would 3 inch Exhaust Hurt my car?

    I was thinking of putting the Dynomax 3 inch cat-back on my 01 Cobra. Would I lose too much backpressure and lose power? Should I go with one of the other 2 1/2 inch systems?

    What H-Pipe will pass California Smog???

    You have to have at least 2 cats in order to pass smog at all (in CA). No cats = No pass. I passed a few years ago on my 95 GTS. I had the Mac H-pipe with cats. Now the catch is, if they look at the H-pipe (while smogging) and realize its not stock, they are going to ask you for the CARB # or...

    me vs 300c

    I have a 2001 Cobra and I raced a 300C SRT8 (6.1 liter hemi) it has about 425 HP (but weighs 4200lbs.) It had a car length on me by the time I hit third. Those things f&^%in fly. I know if we continued to race he would have pulled even more.
