The Mad Max Switchable Blower Becomes Reality at Procharger: SEMA 2012 – Hot Rod Magazine Blog.

What if you could switch your supercharger on and off with the flick of a switch? Many gearheads have had that dream ever since it was seen in the Mad Max movie in 1979. The aftermarket was slackin’, but 34 years later, Procharger has made it real. Or close.
The all-new i-1 supercharger is a belt-driven centrifugal deal like Procharger is known for, but this one can be programmed for the boost curve of your choice by way of a computer-controlled constantly variable transmission (CVT) that changes the blower-drive ratio dynamically. The i-1 blower has a 8:1 gear-driven reduction augmented by the CVT that runs between 0.6:1 and 1.9:1. The drive ratio alters the blower speed and therefore changes the boost.

How is this Mad Max-like? Because you can dial a low 1 or 2 psi for driving around town and then crank it up to the blower’s full potential of around 850 hp, all on the fly. You can also custom-shape a curve to your liking, overdriving the blower at low engine speeds for more bottom-end power, and then tapering it off to ensure you don’t get into overboost. You can also create a flatter boost curve than you would normally see with an rpm-dependant centrifugal blower There are three modes out of the box: Touring for 1-2 psi, Sport for a medium- aggressive boost curve, and Competition for all-out power.
Procharger CEO Ken Jones told us that the i-1 was tested back to back with the company’s mainstay P1SC at the drag strip. The older blower ran 120 mph and the new one ran 122—that’s not due to the CVT, but because of a refined compressor housing.
Ken also says ’10-up Camaro SS will be the first available application, but company insiders have been driving around in 5.0 Mustangs, Corvettes, late-model Mopars, and F-150 trucks. We’ll throw out a guess that the 5.0 Mustang kit will be the next to market.
This is the most creative new product launch we’ve seen so far at SEMA 2012, and HOT ROD is already scheming an interesting way to test one of these things. Meanwhile, you have to check out the video to really understand how cool it is:
