    Ya that's me. It actually makes 714.....but more importantly is the TQ. 680. It makes 600 immediately off idle. The 680 peaks about 3800. Pretty much 100ft lbs across the rev band over those dynos Kona posted. Street light to street light TQ. This is a gen2 2.3 whipple, 2.6 upper/factory lower, 22psi. Factory manifolds. E85

    So, as I've read thru the years the whipple "makes no TQ.....the low end is pathetic" .....I've always scratched my head like "huh?!....that's news to me. My 5 rear tire purchases would disagree."

    Correct. You’re spinning a 2.8 upper like 35% faster than a 3.5 upper.

    Are you being serious or kidding?
