Chad told me that it is normal to loose up to 150 hp from the fly wheel to the rear wheels.
Actually, Chad is way off. A 15% - 20% loss is a generally accepted loss from the flywheel to the raer wheels. Maybe he is trying to make you feel better.

Your numbers are not as far off as you may think. Lets do this ass backwards. 371 rwhp equates to 449 fwhp if you fiqure a 17.5% loss. Add another 50 hp for losses in the side pipes and you are up to 499 fwhp. Torque comes in at 524 fw ft lb. These are numbers I would expect to see from your combination.
