I have an 05-10 GT Forced Air Performance supercharger system for sale. This is their latest and greatest with the biggest head unit Rotrex offers. I bought this kit last spring and pulled it off in November. It has about 2500 miles on it. It is in perfect condition and operates flawlessly.

I have had two of these kits on my car and I'm a huge fan. I ran one for about 3 years and it was great, then I switched to a Procharger F1C. I didn't like a lot of things about the Procharger, so I sold it, and bought another Rotrex system. I would still be running this system if I hadn't bought my GT500 powertrain.

This Rotrex builds power unlike any other Supercharger. It comes on quick and just keeps pulling. Its powerband is a nice combination of a roots/twin screw and a centri. It's very efficient, and dead reliable. And an easy install.

For more information about these kits go to www.forcedairperformance.com.

Included here is the complete kit as it comes from Forced Air Performance, and I upgraded to the new C38-92 head unit (capable of 600rwh+), and it also includes 39lb injectors, MAFia, additional pulley (10lb, and 13lb), new larger air filter, and an AFCO dual pass heat exchanger. Also included are the power steering pump lines that had to be modified for this system.

On this setup I made 486rwh on a bone stock 3V engine, and it's capable of much more if you choose.

The only additional things you'll need with this kit is a tune, and possibly a fuel pump upgrade. That's it.

New price of $3000 shipped.

I've never heard of it, what's the advantage of this over a procharger and what's the max hp potential ?

There are a couple advantages. These are "geared" 7:1 so they build boost very quickly and make really good mid-low range power compared with a typical centri blower. Your Procharger is 4:1. They're also very efficient. The compressor is turbo like, it spins at turbo RPM and is efficient like a turbo, so IAT's are always low and manageable. There are very little parasitic losses because there no heavy internal gears, and the compressor wheel is significantly smaller. So less drag on the motor, and never a worry about belt slip. Also, this system uses an air/water setup for the intercooler. It's very efficient as well. This comes with an Afco dual pass heat exchanger, and if you were to add the twin fans, you would never have an IAT issue no matter what driving situation you're in. The intercooler itself is remote mounted, so it doesn't heat soak like all of the roots/twin screw blowers do when driven hard for long periods of time.

Like a Procharger though, this system uses a dedicated 8 rib belt. I find a lot of value in that alone knowing if there's ever a problem, like snapping a blower belt, or a problem with the SC itself, you can still drive the car and get it home.

How.much boost is the kit making with the stock pulley?

There are a lot of pulleys available for this system, and pulley swaps are a breeze with this particular head unit. The pulleys range in 5mm increments from 70mm up to 100mm. That would equal about 6lbs-18lbs depending on the pulley. What I'm selling includes an 85mm and a 90mm. That should be about 10/11lbs and 13/14lbs. Boost numbers are very dependent on engine setup and altitude. Extra pulleys can be purchased from any Rotrex dealer, or Mountain Performance here in Utah.

Max power is also engine dependent, but I think 650rwh is about the limit of what you'll get from this head unit. There is a guy here in Utah who made 658rwh with this head unit on a stroker with stage III heads, cams and an intake.
