This billet aluminum crank pulley is significantly lighter than the stock steel crank pulley and best of all...it allows for another 10% of overdrive on the supercharger without worrying about belt slippage. Typically adds 3 to 4 psi of boost.
This is the proper high quality belt you will need when running the Magnum Powers 10% overdrive crankshaft pulley.
Typical gains are 20 to 30 HP over the stock inlet plenum, when combined with a 85mm Tbody. Fatten up your torque curve and enjoy the power from the MP High Flow Plenum!
Magnum Powers can re-build your early or late model Eaton blower and save you money!
If your original '89-95 supercharger is in need of a rebuild and you are looking for budget minded performance upgrades also, this is the perfect solution for you.
