      Video Review & Installation

      The stage II ProCharger tuner kit will offer most of the foundation of the popular centrifugal supercharger system but will require 2015 through 2017 GT owners to supply their own fueling setup, in addition to their own calibration in order to complete the kit. Now, the stage II system will also include the P-1SC one head unit which, by the way, is capable of over 800 crank horsepower, along with the eight-rib belt setup and one of the biggest air-to-air intercoolers in the category, all for north of six grand. Install might just be one of the easiest in the category here, but we still are gonna go three out of three wrenches on the difficulty meter as there is a fair amount of work involved, but hang out with me for a little bit longer and we'll cover that more later in the video. So ProCharger makes up one of the big three centrifugal options you'll encounter in the aftermarket, along with Paxton and, of course, Vortech. And the idea of a Century style blower is pretty simple. Its purpose, like any other supercharger, is to force more air into the engine, and as a result, make more power. Now, on the surface, a centrifugal supercharger will resemble that of a turbocharger at first glance, at least on the compressor side here. However, the big difference between the two is that the Century is going to be belt-driven whereas turbochargers are, of course, driven by your exhaust. But the power delivery of a centrifugal like the ProCharger here is going to be pretty similar to that of a turbo where it builds boost with RPM, unlike a TVS style blower, for instance, where the power delivery is very linear and pretty much on tap at all times. But now that you know a little bit more about how it all works, let's break down the ProCharger tuner kit a little bit further. And full disclosure, guys, there are more components that come along with this system. I just have some of the meat and potatoes out on the table here for the purpose of this video. Now, at its core, you're gonna find the very popular P-1SC head unit. Now, the P-1 is one of the smaller offerings from ProCharger compared to an F1, for instance, but will still be able to support upwards of 825 horsepower while flowing a max of 1,200 CFM. Now, your max impeller speed will be 65,000 RPM, and that will allow the P-1 to achieve max boost levels of 32 PSI, although most setups won't see anywhere close to that. Typically, I'd say for the S550 GT owners, you're gonna be looking at the 8 to 10-pound of boost range right out of the box with this setup. Now, driving that P-1 blower will be the included dedicated eight-rib belt setup which is, by the way, a very nice upgrade over the base six-rib kit. They also toss in an eight-inch crank pulley that does work in conjunction with your factory harmonic balancer. So, there's really no need to drill or modify any of your factory parts. Now, ProCharger actually claims that this does take some of the stress or load off of that crank snout and pulley, which can be an issue, although rare, on some of the older or different setups. On top of that P-1SC, prospective buyers can also look forward to this absolutely massive air-to-air intercooler, definitely one of the largest in the category when checking out the stage II kit from ProCharger. In fact, you're looking at 1,100 cubic inches of core size here, which absolutely dwarfs the 600 cubic incher of the basic high output kit. Best part is, ProCharger states you can fit this behemoth behind your factory bumper with no cutting, no drilling, or trimming of any factory parts, which is very impressive. Finally, guys, that intercooler does include all of your piping, in addition to all of the brackets needed to get everything in place. Again, I do come back to that whole tuner kit thing, guys, and that does mean you will have to provide your own fueling and calibration for this particular kit. Now, ProCharger does offer a complete kit on the site here that does include a fuel pump booster from JMS, in addition to Deatschwerks 1000cc injectors and an engaged loaded with a calibration from ProCharger for about $1,500 more, which really isn't that bad of a deal, in my humble opinion. So, if you want a turnkey system, that might be the better option for you. ProCharger also claims that this will be one of your easier forced induction setups to tackle on the S550 Mustang and one that is completely reversible, meaning there's no crazy cutting or clearancing needed to fit all of these parts. But because we are still talking about a supercharger job here and not a cold air intake, for instance, we're still gonna go three out of three wrenches on the difficulty meter here and at least a full day in the shop or garage to get everything knocked out. So wrapping things up, guys, if you're looking to save a few bucks by providing your own fueling and calibration, the stage II tuner kit from ProCharger would be an excellent choice, and you can check your system out right here at
