Powerdyne fit a Corvette?
I broke the internal belt about 4 times when i switched to a smaller 8-9 PSI pulley
But i do know on a stock LS1 F-body at 6-7 PSI they work pretty good.
I have seem a car run high 11's at 116 , with the powerdyne and exhaust + headers , tune and upgraded fuel system,
but for your car the Procharger D1-sc is the only way to go supercharger FI.
I have a D1-sc on my 01 SS and am very happy with it , It was a good choise for me
but you will most likly have the replace the internal belt 1-2 times a year ,
go for it , you cant beat the price, good luck
