Subject: Re: Driving impressions with the AFR heads by TonyMamo on 2009/8/7 4:33:42 Excellent.... I was expecting the top end charge to be the area of greatest gains....thats when airflow is at a premium and every little bit extra helps. Also, the largest disparity in the two heads was on the exhaust side and that will always help the motor make more top end power when there is so little time to evacuate the cylinder. If you cant make room for the next intake charge, power starts to roll off rather quickly because you aren't filling the cylinder with a complete fresh charge to light off... Looking forward to the dyno/track results....don't forget this head may need/want completely different fueling and ignition timing requirements. The fact you can already see/feel a difference (and considering the unlikely scenario that the WOT tune will like everything exactly the same) is very encouraging. -Tony PS....Hey Matatk, I could really use your BS meter for a unique opportunity on another board....LOL Great sig photo....dont know how I just saw it now! |
