Butler Custom Pontiac Procharger Serpentine Drive Kit, Up to 925 hp

Take your Pontiac to the next level with a Butler Custom Procharger Serpentine Kit. For Pump gas 93 octane we suggest a compression ratio of 8.75-9.5:1 on aluminum heads depending on pulley size and boost level. If you currently have a pump gas compression of 10:1, you may be able to achieve this compression ratio simply by changing to a thicker Cometic head gasket that we offer.
