I have been mainly looking at the Paxton, Vortech, and Procharger. I like the Procharger HO kit because it does not require any cutting. My usage will mainly be for street usage. I may go to the track on rare occasions. I want 550-600 rwhp which I know is achievable with this kit. My main questions are how much hp can I pull out of this kit safely, and how bad is the heatsoak. I have read tons of info on other sc'ers, but not a lot on the stage 1 kit. I know I can go with other setups, but I only want to here pros and cons to this one.
