How Do You Convert Rwkw To Flywheel Kw

[luke187]

Is it really a flat percentage? How much torque would it take to power my diff and rotate my wheels? Lets say it took 50ft/lb. Swap engines to ones that's making double at the flywheel, is my diff now going to take 100ft/lb to turn the same speed?

I cant imagine a 1000hp car losing 200hp through the transmission either. Something that ive never found a straight answer on lol, be nice for some people to share what they know. Was also thought there was an unusual amount of people making less than 200rwkw! Go the mine.

there IS NO SET RULE/PERCENTAGE/ANSWER!.

The only way to be sure (and with this method the percentage could change depending on how tight you reinstall all of the bolts...) is to take the engine out, measure it's flywheel kW with an engine dyno, then reinstall the engine and measure the kW at the wheels with a chassis dyno (with the same calibration parameters as the engine dyno) and then manually calculate a precentage between the two figures. Any other answer is just either a complete guess or an educated guess going by past results with similar setups.
