Did you know that the stock Powermax Turbo comes with a horrible cast compressor wheel that will cause a slow spool up, high EGT's and low power? These downfalls are the reason why KC Turbos came out with their 300108 Billet Powermax Compressor Wheel. This drop-in 63.5mm Single Plane GTX style Billet Wheel solves all those problems and will make it feel like a completely new turbo. They are simple to install and will help improve the performance of your turbo. KC Turbos testing has shown that the 11-blade single-pane wheels perform much better than the OEM dual-plane design. This wheel also comes 100% component balanced and is a MUST HAVE for your Powermax.
