Thread: First Time On the Dyno

I don't have a formula.

But horsepower is calculated by timing the acceleration of a known amount of inertia from one rpm to another. (Work/time, lb ft/sec, or power)

Knowing engine rpm, torque can then be calculated.

by your own words. Calculated. Ft/lbs per second is a measurement of Torque. Not a calculation.

But we're off track if the graph doesn't cross at 5252 then something went wrong. Believe me I am doing measurement all the time and you will get erroneous readings here and there. Sometimes you know what caused it others you don't. But the operator should know to throw that out.

I didn't make the rules on how an inertia style dyno works.
