Every Drag racer I have spoken too, all say the same thing, that on the up-shift you want the revs to fall back to peak torque, which is why a lot of us are saying that knowing the torque curve of an engine is more important.
and we all know that drag racing is all about acceleration,
I know you guys are saying that the mechanical advantage increases torque at the wheels, but depending on how quick it drops off may mean that peak engine torque still gives peak tractive effort at the wheels.
I really wish i had more time to be able to get right in depth like a lot of you are.
