Conversion factor for RWTQ
Does anyone have the conversion factor to find out what my RWTQ is? I know how to convert for RWHP from the dyno, but what about RWTQ? thanks in advance

To the best of my knowledge, there is "no" formula to convert HP to TQ.... otherwise everyone with the same HP would have the same TQ numbers.
It's safe to say that I think most people turn more TQ than HP at peak but I'm sure someone out there can prove that wrong.

Engines produce torque; torque wins races; horsepower is just a BS math calculation to help sell cars. If you can rev your engine higher, you will produce more hp. A dyno just measures torque and RPM and plugs the numbers into a formula for HP
Horsepower = torque x RPM/5250
notice on every dyno sheet that HP = Torque at 5250rpm, before that torque > HP and after HP > torque
MN6s should have about 15% loss between the flywheel and the wheels, so to get FWHP from RWHP:
FWHP = RWHP/0.85 & FWT = RWT/0.85
or for an auto, you can expect about 20% loss:
FWHP = RWHP/0.80 & FWT = RWT/0.80
FWHP - Flywheel horsepower
RWHP - Rearwheel horsepower
FWT - FW torque
RWT - RW torque
