My setup used a Vortech V7 Ysi supercharger. I bought the BBC kit from Superchargers Online and adapted it to the FE. I made 1200 HP with that setup on my 500" supercharged engine, but I needed a big air to water intercooler filled with ice to do it. I had originally settled on the Vortech unit because it was small enough to fit under the hood of my Mach 1.
In order to get the boost up to 17 psi I also had to go to a toothed belt drive. The 10 rib belt that you get with the Vortech kit started slipping at around 10-11 pounds of boost, and wouldn't go any higher.
When I got the setup in the car I had cooling problems due to the position of the air to water intercooler box. I had put it right in front of the engine, but in that position it blocked a substantial portion of the radiator, and the car just wouldn't stay cool, even just idling. Lesson learned there was to put the intercooler box in some other location, the interior or the trunk, whatever. I didn't want to cut my Mach 1 up to do that, so I just eliminated the intercooler and ran straight from the supercharger into the carb hat, and added a "Boost Cooler" methanol sprayer system to try to keep the inlet temps down. That ended up working pretty well, and I wouldn't hesitate to do that again.
If I had to do it all over again I would reconsider a Procharger setup. I rejected them initially because of the fit issues under the hood of my Mach 1, but looking at their specs it would have been a lot easier to make the power I wanted with a Procharger. If there was some way to make it fit, I think it would be a better solution than the Vortech.
Here's some pics of my setup. I started off with a carb box enclosure, as shown below:
This turned out to be such a pain getting to the carb to make any adjustments or changes that I bailed on it fairly quickly. It also did not make great power, around 850 HP if I recall correctly. Next I went to the carb hat, as shown below:
I also switched to a solid roller cam in this iteration. This got me to 930 HP on the dyno, but with the 10 rib belt the boost was limited. Next I went to the toothed belt drive, as shown in the photo below. I had integrated the induction system with the shaker hood scoop, so that air came in through the scoop, went to the supercharger, and then came out and went to the carb hat which was also integrated into the air cleaner assembly. On the dyno this setup proved to be very restrictive and cost at least 200 horsepower. I ended up running the supercharger inlet open on the dyno to make just over 1200 HP.
Here's a picture showing the engine originally installed in the car, with the intercooler. You can see how that box blocks a good portion of the radiator.
In the end, to make the engine fit and work in the car I had to ditch the intercooler and suck air from outside the inner fenderwell. This certainly cost some big power, and in the car I don't think the engine was even making 1000 HP. The car ran a best of 9.35 at 151 before I took the supercharged engine out and went back to naturally aspirated.
Hope that helps, and good luck with your project - Jay
