When considering a dyno run everyone says you average 20% parasitic loss for the drive train. Cool, I agree. 300 crank HP motor makes 240whp. So then for a 600 crank HP motor is should only take the original 60hp to spin the trans drive shaft and related components right?

But this is where it begin to defy the laws of Physics. People still argue it takes 20% so a 600 CHP motor would lose 120hp and only show 580hp?

How is this possible? Nothing changes, where is the mystical HP gremlin eating all this HP?

Now, consider this! If an alternator takes 15hp to run and you take it off the 300hp motor and put it on the 600hp motor why does it not take 30hp to run? this argument could be made with anything you attach to the motor right?
