This is what I never understood about parasitic loss through the drivetrain...Lets assume you start with an engine setup that makes 400hp at the flywheel and assuming 20% drive train loss, you should expect to see 333hp at the wheels. A 67hp loss. Now, you start to mod the motor and when you are done, you are making 550hp at the flywheel. Still assuming the 20% loss, you are now making 458hp at the wheels. a loss of 93hp. Since no other changes were made to the drive train, the power loss should have remained constant at 67hp. Parasitic loss of hp through a torqueflite with a specific torque converter and dana 60 with a given set of gears should be constant regardless of the hp the engine is making. Correct?
