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.
Includes custom cnc plate, head block, brackets, pulleys, procharger head unit, tensioners, and all necessary hardware (newly designed brackets in 2021) Fits under the hood of most Pontiac cars. Works with alt and ps.
Will not work with AC Evac
