Heres an example of how cars making the same peak power, but one pulls harder on the top end!

My olds...468ci 530hp peak at 5600rpms/ runs avg. 11.60 1.60 60ft @ 111-113

2010 camaro LS3 , add headers and cold air.. flywheel hp is about 490@ 5900 The camaro still turns at lest 112mph ( matches the more powerfull olds) but slower in the 1/4 at mid to low 12s.

The reasone MPH is the same even though the camaro makes LESS power is becuse its usable peak power hangs on longer, it might peak at 5900 but it still pulls hard to 6500! Over shifting helps make faster Et's because the engine breaths so well and at high RPMs the motor is still pulling like bull!

My olds with MORE power, after 5600rpms peak power... power falls off Fast! Over shifting slows the car down, I would short shift 1-2 at 5100rpms and the car was faster!

But the olds make so much usable power /torque from 3000-5600 that at the 60ft and 1/8th mile the car is a monster, but topend suffers because of the dip in power after peak! Match the LS3 at 530hp and topend will be much faster then my olds, and will start to play catch up in the top half of the track, but it will NEVER 60ft or 1/8th mile the same!
