what do you guys think is the average conversion factor from wheel hp to flywheel hp on dynojet type dynos? the magic number seems to be between 10-15%...
Hypothetical situation:
You've got a car that makes 100 hp at the flywheel, & 75 hp at the wheels. After some modifications, it now makes 200 hp at the flywheel.
Does it make sense that the exact same transmission, axles, bearings, wheels, tires, accessories, & peripherals would now sap twice as much power as they did at the original power level? By assuming drivetrain losses is a fixed percentage, this is exactly what we're predicting.
Something to think about.

Most say multiply by 1.15 or 15% just as a general number. I don't think it really matters personally. If you wanna know yank it and put it on an engine dyno.
