Just remember the Dyno give you CORRECTED HP numbers.....corrected for perfect air.......Now where in the hell in this country does a racer find perfect air...so the actual HP is going to be less in the car....
Also the engine does not run down the track at PEAK HP rpm...it has to launch ,,,rpm has to come up...shift ..the rpm gets dragged down to converter stall or thereabouts...and the rpm must accelerate and shift again...so usually plugging in the peak hp will not give you a correct et or mph....Plugging in the peak hp will give you a Fantasy ET...
