It never converts...
For example...someone has a stock Suburban that makes 300 rear wheel hp. Someone thinks that 20% losses substantiates 360 at the flywheel.
Person puts a supercharger on his sub, and now he's making 410 at the rear wheels. Same math says that should substantiate 492 hp at the flywheel.
Why did the driveline losses go up with nothing but a supercharger install ?
(60 hp driveline losses stock...82 hp driveline losses with supercharger)
Percentages don't work to backcalculate to the crank...
