We all love these wonderful cars so I guess that makes us brothers in a way. Brothers can often squabble over little things some time. So no harm no foul.

Respectfully, but I think you are miss interpreting your equation.

P = (T x W)/5220


HP= (TQ x RPM)/5220

The P is Power and or HP.

Depending on weight and power or HP you determine your rate of acceleration.

Thus, Power to weight ratio.

A bigger P the faster you go. The lower the weight the faster you go.

To make P bigger there are two things you can do. Increase T or W. Correct?

The T is torque. We measure torque in 'ft lbs'. This is the amount of the 'force' of one revolution of the motor.

Or, you can increase the W. The W is the multiplier of Torque in your equation.

Said multiplier, or 'frequency' of said force is of course how many Revolutions we can fit into a Minute (RPM).

Again, to make more Power or HP we need more Torque and or do so at a higher frequency (RPM) .

Forget about the 5220 'factor' for now. TQ and RPM are the variables that effect P.
