I have seen it. The guy was datalogging baseline nums with the Gords liquid cooled set up also. I actually didn't see much custom fab work with his set up. This was 2 years ago and I don't know how to find that guy now. He was an engineer for sure.
its done quite often, and from what i've seen it fits without much modification at all consider the vortech/paxtons have the same location for the piping to go. People do it all the time. Check at modularpowerhouse.com forums, I know they've done it numerous times
Check out my sig. Exactly what i have on my setup. Fits PERFECT, no problems at all. All you have to do is re-clock the blower and trim the discharge tube.
