Subject: Re: Dyno numbers for AFR heads by TonyMamo on 2009/9/1 15:52:20 Josh, Thanks for doing all you have done in an effort to provide us with quality data to compare. Thorough A-B testing and eliminating variables always makes these types of things far more challenging. Personally, while Im obviously thrilled with the HP gain, Im more impressed with the immediate and substantial gap in torque thru out the entire power curve but especially in the middle where there are fat gains in all the real world RPM range most of us take more advantage of. That's power you can feel and appreciate just driving it "normal" every day and not having to delve much deeper into the higher RPM range to appreciate and experience the difference. Of course in theory, thats where an efficient higher flowing smaller runner shines and this curve is the perfect testimony to that fact. Looking forward to the track results....Im sure Beach Bum is inputing the difference into his simulator right now saving you a trip to the track and the admission fee....LOL My guess is a couple of tenths and a couple of MPH but I wouldn't fall over if it was a bit more because of the gains in average power. Also, Im thinking the track wont nearly have the same D/A in the August heat so we will have to correct it back to the same D/A you ran the other combo in assuming you have that data. Thats the problem with track comparisons....weather and track prep can skew results in such a huge way. Good stuff... Cheers, Tony |
