Driveline Loss at High HP - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Whenever I see discussions regarding the driveline loss it is always expressed as a percentage. For the L99 for example, is seems to be somewhere around 18%. Does this same percentage hold true for higher HP cars? Is the RWHP of a 1000 HP motor 820 RWHP (driveline loss of 180 hp)? Intuitively it would seem that the driveline loss should remain constant. Why then is the loss always expressed as a percentage.

No one can tell me if the driveline loss remains constant with increased power or is always a precentage?

Drivetrain loss is an average based on parasitic losses as well as centrifugal forces generated by rotating mass. The centrifugal force is not a constant and increases with HP, this is why the average holds relatively close as HP increases.
