Procharger Supercharger Systems compatible with Standard Pulleys:
Looking to increase the amount of boost out of the Procharger system on your Ford Mustang 3.7L? Grab yourself an ATI Procharger Blower Pulley! These pulleys come in a broad range of sizes and 6 rib to fit your Mustang's unique setup! Keep in mind that a better flowing system will make less boost and requires a smaller pulley to regain the reduction in boost. However, there will still be an increase in power. This pulley comes with the retaining bolt, washer, and key.
How to figure out pulley size:
- Never strike the ProCharger pulley with a hammer or other tool under any circumstance! Evidence of such force will void the warranty, as serious damage to the precision bearings within the ProCharger could occur.
- Belt is not included with pulley purchase.
- Increasing boost levels to unsafe levels can result in ENGINE FAILURE.
Let's say your pulley is a DP400I-06D. 400I means this pulley is a 4.00 diameter size. The 06D tells you it is a six rib. If you have any questions or aren't sure just give us a call or send us an email. We will be glad to help you out!
