Gross is at the flywheel with no accessories, no air cleaner assembly, no stock exahust manifolds/mufflers (used headers with open exhaust), no emissions, no alternator, etc etc. Net is also at the flywheel but with all stock/standard equipment in place. Stock exhaust manifolds running through stock exhaust, stock air cleaner assembly, alternator, emission equipment, etc. The factories do not do any HP ratings at the wheels, that is a Hot Rod/aftermarket thing. All factory ratings are at the flywheel. tom... |
