drivetrain loss????

Very interesting topic!

Cyberstang: Here are the formulas for hp and torque.


Torque = force * moment arm length

Hp = RPM * Torque / 5252


If two engines make the same hp at the same rpm then their torques will be equal.

If the engines have the same hp but different torques, this would be due to being measured at different rpm's.


Here is a quick example of two machines that have the same hp but different torques. Notice that to do this, there must be a change in rpm.

2000 rpm * 262.6 ft-lbs / 5252 = 100 hp

or

3000 rpm * 175 ft-lbs / 5252 = 100 hp

If rpm's increase, torque has to decrease to keep the same hp.


Hope this helps out a little.
