Hey guys... I am very interested in doing this set up. I have a 2009 SRT8 and I have been speaking with the guys at RDP Motorsport in Ohio on doing a Twin Turbo set up which is what I really thought I wanted to do. Those guys really seem to put out some good work and high HP rides, but after checking you guys out you seem to as well and your past customers don't seem to have any complaints. I just liked the idea of something I could get past the 650-700HP range if I ever wanted to and liked that it wasn't as common, but at roughly $13,000 (which included headers and exhaust) it was going to be a while before I'd be able to do it. This is a driver btw (about 800-1000 miles a month). I've read great things about prochargers on here and your set up seems very economical which puts it much closer to getting done for me (about 6 months). I like that you guys guarantee the 555hp too. I am just curious...before I would do this I would like to have Kooks long tube headers and a full exhaust (most likely Zoomers) and am curious where you would roughly estimate the HP range to be with that set up? My goal is to get between 650-700HP. I don't want some crappy GT500 or Z06 leaving me in the dust!
