You need both, HP and TQ, Can't have one without the other. I want a lot of HP with a lot of TQ.

These questions/topics are non-sense.

Horsepower is a function of torque.

If you know the torque and rpm anywhere in the powerband, you can calculate the horsepower.

It's a simple formula.

Hey Luke, isn't it torque times rpm divided by 5252? I think that's it but not positive.

It depends on the type of dyno as to what is measured exactly. Dynojet or inertia dynos measure horsepower, while load-bearing (dyno dynamics, mustang, etc), directly measure torque. Then the other figure can be computed mathematically if the dyno is able to input engine RPM.

HP = TQ * RPM / 5252

At the end of the day, I am all about horsepower "under the curve" or average horsepower.
