433rwhp in hot ass weather on 91 octane..... 415rwhp is down on power slightly imo, i dont think ive seen a vt2-500 put down less that 420rwhp mine came in quite abit higher but again was in cold weather with 105 octane fuel- 8psi pulley,...... but so many factors effect that..... weather, fuel, heat soaking ect ect....
im really looking forward to getting back to the dyno this year and getting some definitive warm weather figures.....
