RX8 Performance.com Pulleys

A fresh approach.....and a fresh result!  When we set out to develop aftermarket pulleys for the RX-8 we were aware that the current offerings were designs that were essentially, appearance items. Designs based around theory and not RX-8 specific data, we wanted to develop something different, pulleys that actually made a difference.  With our approach we have reduced waterpump cavitation at high rpm, improved power output and reduced operating temperatures leading to improved engine reliability! Even better, we have developed a combination that most enthusiasts can enjoy the benefits of on their street cars in daily driving situations as well as during competition or track day use!  For street cars under drive percentage is always a balance and we have found a combination that passes the idle and low speed tests and makes more power through the majority of the rpm range as well!      We have included our results from a recent street car dyno test session. These results were obtained b
