I just had my 2004 gto a4 on my dyno today , i installed CAI and JBA shorties , And i was tuning with EFI live ,
Base line dyno run i got 304whp
With kn CAI and some minor tuning i got 315whp
With JBA shorties and more minor i got 330whp
Made quite a few runs and intake temps were in 150f range with a fan blowing close to the CAI , This killed the HP as the IGN timing was in the 14 deg range , let the car cool down and back to good numbers again ,
I did quite alot of data logging on the dyno and the street ,
I think i am going to re design the KN CAI , i think it takes to much hot air from the engine compartment and the hedders made the engine compartment temps go up quite a bit , these cars seem to be very sensitive to air temps
I have heads , cam and exhaust for this car as im going to make it a 500+hp car when im done , But i want to do it in stages , i own a dyno so i can test every part
Any one else have air temp probs with the KN CAI ? , car also drops power badly on a hot day , I think if i redesign the KN to get 100% air from outside the engine compartment there will be a big gain here .
