Stock GT 5-speeds are putting down about 188hp and 253lbft to the rear wheels. You have about 27hp/23lbft more than stock which, I reckon, is right on the mark.
The GT40 intake doesn't yield anything like 15hp; more like 7hp. Add 5hp for the mufflers, 5hp for the Prochamber, 7hp for the CAI, 3hp for the TB, and you're there.
The temp. doesn't matter because the dyno numbers should already be corrected for atmospheric conditions (elevation, barometric pressure, air temperature, humidity).[/QUOT
wait a minute, Ur saying a cold air intake, (Which in my opinion is pretty useless) would put down the same numbers of the Gt40 intake.... no way.....if that cold air intake could gain u 7 hp...then that gt40 could give u 7000.
Mr. Grady :I agree with that ......but the part i cant and will NEVER agree about is the cia giving u the same power gain as a gt40, or any other non stock gt manifold would......i cant even see how anyone could compare the two
You're forgetting that the GT40 intake in question is still attached to stock heads. If the heads were higher-flowing, the GT40 intake would produce a bigger gain.
