On a stock 99 saleen supercharged, how much of a differnce can i expect off of a new cai compaired to the stock one. If a stock car picks up about 20 flywheel maybe it would be realistic to say 15 rwhp for me because its being forced? What gain is picked up off of headers as well.
Very subjective question around here. I would call Saleen's Customer Service and ask them or post in the Saleen section on the boards. You will get optimistic estimates upward of 20 for CAI and 40+ for long tubes and them you will have the negative camp that will say CAI's aren't worth the money, period and that long tube headers are only good for 15hp and every reason in between about why. So I would just make the call.
