I give up next you'll try to explain how your leaky unbalanced lump of crap motors are more efficient cause they are made from lead or something.

Let's say I'm putting down 35ft lbs. I turned my wrench 15 degrees. 15/360X100 gives you your percentage of a revolution. This gives us 4.1% of a rev or .041rpm. (35x.041)/5252= Somethign like .0002hp. So, you could say you've done .0002hp of work while you were using your tq wrench. But, most people would know that you've used 35ft/lbs to tighten your bolt. Because, they can feel a 35lb weight. Most can't feel, .0002hp or even begin to tell you how hp works, or what it is. Are you bashing my bike? |

That is where you get your horsepower. It is a measure of how efficiently your torque can be continued to be used. |

![]() This isn't psychology! Both numbers are real and have meaning. You just have to understand a little science. An IC engine CANNOT apply a useful force at 0 RPM- at a stall. Torque is a measure of force applied at a distance. C'mon, you can apply all the force you want to something, if it won't move it doesn't much matter- you're not doing any work. If you have 200 ft-lbs of torque available, and the chain holding the bike back is rated at 20,000 lbs you aren't doing shit or going anywhere. Horsepower is a measure of work done (or energy expended) over time. Same as a Watt or BTU. You don't argue that your engine is working, or the heat coming off your hot water heater is imaginary, do you? You could easily convert that BTU or Wattage number into HP. Your engine does work to move your ass, and the water heater does work to heat water (changing the amount of thermal energy).

I'm not saying hp doesn't "exist". You just don't feel it like you do torque. Much like latent heat can't be felt, but it is there. |

Actually it measures force over distance which we humans express as torque it can just a easly be expressed as HP.

Your torque curve drops off? Sucks to be you!

I truth a dyno measure electrical energy produced when a large drum is spun with a load. So I guess it measures watts.

![]() Watts are a measure of work. They are a function of amps, ohms and volts. ![]() So, if you're drum is measuring the electrical resistance to get it up to speed, then watts would be a function of ohms and rpm, wouldn't they? |
