I recently bought a 01 Cobra from another member on the forums here. I called my F150 tuner Mike from Troyer Performance and talked to him about the ATI Procharger P-1SC editions to which he said they are good little centri blowers but at about 12-13lbs their maxed out. Well the car has a built motor by Excessive Motorsports and was tuned by Jon Lund at the Evo Performance shop that makes 452rwhp with 14degree timing via a Mustang Dyno. I went on the ATI site and checked out some of the other peoples Cobra's and even GT's in the gallery section with that same blower and all but one seem to make about 50-100rwhp more on 93 than what I make. I was told Jon Lund likes to run 18degree timing and it would have made about 500rwhp but the guys on that site are running low Boost #'s like around 10 but I'm not sure if it's lbs or PSI, I will assume it's PSI and are making 500rwhp (so they say) with about the same mods as me. How far can these P-1SC chargers go safely? Here's a list of mods if that helps and can anyone explain the difference in PSI and LBS or how to convert it? I know how blowers and turbos work I even know about the BAR system used overseas but some people say lbs and some say psi when you talk about them. I have a roots style blower in my truck running 8.5psi but how many lbs is that?
