Is Torque King?
It seem from most of the responses that people see that torque does the work from idle to 5252 rpm than horsepower takes it from there or torque launches your car and Horsepower takes it from there. Horsepower does all the work from idle until your engine can't spin any higher.
On a Dyno your engine is being measured for two things RPM and Torque and the horsepower line is calculated from the two it's the Sum of there combined abilities.
Visually torque curve works better for the way our brain perceives info, all the same info is there in the HP curve.
