Question No pics for this one!

Which mathematical relation which links power and torque values where T= torque, P= power, V= throttle opening percentage, n= RPM?

Not sure what you mean. Could it be...
ft. lbs.torque x RPM / 5250 = Horsepower?

I might understand the formula but am not sure of the point or the useful application. Maybe for estimating fuel efficiency. The effect of "V" will be all over the place depending on "n". Unless "V" should be "percent of maximum flow" rather than "opening percentage". I'll wait for the answer.

P = 100%V*100%n

who cares about T anyway you V-twin riders

No. I can't believe I have put this much thought into this. Unless I am missing something, Torque (which is a force) is the only measure of power among the listed variables. Throttle opening percentage is a percentage, RPM is a measure of rotational speed, of which torque is dependent upon.

To common sense it out, "Power" is a measure of torque, which depends on the RPM's, which depends on the amount of throttle applied. If that holds true, then for a given moment in time, P=T=n=V

My head hurts.


*Edit*
I just realized you were talking HP, not simply "power". Disregard all above. Someone needs to be more specific in their wording

Don't try to keep up with my life, you'll only get hurt.

Is this it?

Tourque X RPM X Throttle% = HP

I found out a few things and i think i am pretty close at least

or same as......TNV=P

Howz this:

power (horsepower) = throttle opening % X torque X rpm

?

Or a different way of looking at it : hp = torque x rpm, so presumably torque is max torque x % throttle opened.
