[Shotimes] Daytona 500 & NASCAR HP

[cmichaelo@optonline.net]

I know of the HP/TQ relationship, but that doesn't help when I don't know the HP curve.

Usually cars don't make peak torque at max rpm. So it doesn't make sense to calculate TQ from 850HP @ 9000RPM, unless we know that the car makes max TQ at 9000RPM.

I guess I should have been more specific and asked what is PEAK torque for the Nascars?
