Hey T&P. Remember that one person telling us that HP is just a calculation and doesn't really exist like TQ does? Lol

LOL, that guy was right. Look up the definition.
You will notice that 'torque' is the measure of 'work'. Work requires a force. That force is torque. All horsepower adds to the equation is time, so horsepower is just the ticking of the clock.

This guy quoted below works with horsepower all the time for his livelihood and this is what he has to say about it.

What This Means
As we proved above, horsepower is simply an extrapolation of torque applied over time. When an engine is measured for its power potential on a dynamometer, horsepower and torque are not measured as separate entities. Rather, torque is measured, and horsepower is then calculated given the torque at the specific RPM level.
Car owners often use “horsepower” as the end-all be-all rating for engine performance. This perspective is flawed. First of all, when you hear of a car having X horsepower, it only refers to the peak horsepower on the dyno graph. Secondly, it doesn’t indicate what the shape of the torque curve is. You can feel the torque that an engine generates as you’re pushed back into your seat.

Bye,,,,, again.

But if you are talking about a chassis dynamometer (that is what you will find in the field)
They measure horsepower and the torque has to be calculated.

Also torque is not a measurement of work. Torque is only a force measurement. You can have a 1000 ft lbs of torque with no work being done.

But if you have 300 hp work is being done.

When you are being pushed back in you seat that is horsepower.

Being pushed back in your seat is torque overpowering the resistance. Horsepower is just a mathematical calculation that tells you how much torque you are putting out to overcome that resistance.
