[QUOTE="Steveespo, post: 14298164, member: 129513"] Boss motors make 385-400 RWHP stock, SAE, depending on the engine and dyno, GT motors do 365-385 RWHP same conditions. Boss rating of 444 flywheel is pretty close. GT uprating of 420 was more accurate than original 412. 10% driveline loss is pretty accurate with the MT-82/8.8 rear and their synthetic fluids. Strong 2015 GT motor should make a little more than a "weak" Boss motor, about 390 at the tires. Can't wait to see dyno and track numbers. Steve [/QUOTE]
