Default What is my RWHP????

LS1-dyno before heads/cam delilvered 326 rwhp. Car is automatic so I expect a 20% power loss to the wheels. The heads and cam should represent a power increase of 75 hp. Is this at flywheel or at the rear wheels. This will obviously affect my outcome numbers. If it is at flywheel then that is 60 net at rw's. That converts to 386 rwhp or about 480 at flywheel. If the 75 is net to the wheels then that would be 500 at the flywheel. Let me know your thoughts.

I would figure more like a 25% drivetrain loss at best. Your gain is going to be at the motor. Unless they put rwhp next to the gain they claim then its most likely going to be at the motor.

The amount of power you gain can cover a huge range depending on what cam and heads you are using.
