I have a Dinan (Powerdyne)Centrifugal 6psi unit. I am very happy with the performance and especially the reliabilty. I will upgrade to a 7 psi pulley for more boost. If you go with the Dinan, get the new Vortech they offer which is very good too but a bit more expensive. There is only a little bit more bhp rated with the Vortech than the Centrifugal unit. But you can make it up with other goodies. You are going to ask yourself how and where you going to drive your car. I go to the track maybe 4 times a year and its a daily driver so I opted for reliability. Good luck.
