Your confusing drivability, or perceived responsivness...with HP, the issue isn't really which makes more power, the 750 wins, almost everytime,people say all you "need" is a 570, or a 650 etc, based on a formula that Vinnie is referring to above. And its accurate, but flow is flow......if your building a performance motor, you want flow, and in this instance, for sheer numbers, bigger is better....on the dyno, the 750 will outperforme the little 570 every time......
