I am gathering my mod money to put a whipple on my 03 cobra here in the next few weeks. I've played the twin turbo game. It was fun, but more were into it than I was. Call me crazy, but I like the boost from a supercharger rather than a turbo. I want to cross the 600hp mark and realize either whipple can achieve this. I want to play in the 600 range for the time being, but I also know I may want more down the road. So what is the deciding factor in order to choose? Sorry for the rant, but I hope you can see that I am really torn between the two and not just asking a question. Thanks for any help. Brian.....
