Got my car dyno'd on Saturday, Running .6 bar of boost standard ecu and engine on a hybrid. The car made 129 BHP at the wheels. And it made 184 NM's of torque at the wheels, how do I work this out to flywheel torque. I was told a rough estimate to get flywheel BHP is 20% of WHP and add it on. How do I workout the flywheel torque?
