Torque Equation
Anyone have a theoretical equation for Torque that doesn't use HP or VE? I have all engine specs but no actual measurement data on the engine. (But if I needed to plug in say Cam specs, I could).
I found one for HP that uses Air Pressure, VE, CID, Comp Ratio and RPM. That gives a theoretical plot of increasing HP with RPM. Actual numbers will be different once dyno'd, but for a ballpark prediction good enough.
If I use the HP values from above in calculating Torque, the result is the same over all RPMs - no surprise, VE is fixed which is not the case in the real-world.
So I'm looking for a theoretical Torque equation that doesn't use HP or VE, but other engine specs that I can plug in to get there. The other option would be to find a theoretical VE curve over RPM (carbureted motor version) and use that to calculate the torque. I have googled extensively but with no luck, all I've seen is T equations that use HP somewhere.
