Well finished up the Vortech install and finally got my computer back from Vortech today. I was so disapointed in the performance of the supercharger I just couldnt beleive it. Everything on my car is stock with the exception of the Supercharger, But I ran a 125 shot of NOS for 3 years and it totally smoked this supercharger. Just disapointed right now and dont know what to do I thought this thing would be atleast close to the Nitrous but wow was I wrong. I suppose Now I will be looking for ways to maximize this blower. It is a quality product , but just dont quite have the kick I am looking for. From what I understand it came with a 8 PSI pulley perhaps I need to look at upgrading the pulley. My Auto transmision was also not wanting to shift properly on the chip I was sent. Man i am frustrated!! So from here what is the biggest bang for the buck for me? I just spent several thousand, but need to look at some less expensive options.
