I was just wondering how many people have had valve spring float issues when they use a S/C? Im buying a d1sc and want to know the odds of having this prob. Im eventually gonna build the car to be strong top to bottom once its paid off a year from now and im hoping to be able to run just the supercharger and some boltons for a while. I plan on a pretty safe tune and am hoping to see about 450ish. I already dynoed 342 at the wheels and from what ive seen on some of your cars 100hp gains are pretty easily attained. I will definitely dynotune. any help, experience and advice would be great. thanks jesse
