Supercharger electronic boost regulation

[Boostjunky]

I have been looking at Kenne Bell superchargers and other brands for Jeep 4.7L V8s(twin screw vs roots type). I known what a bypass valve does, but its there a way to electronically adjust the boost level on the fly? Similar to a rice burner turbo set up with boost controllers. I would like to run 3 boost settings, 3psi, 7psi, and ~10 psi. 3psi for everyday city and snow driving, 7psi for highway etc, 10 psi for putting rice to shame. Would it be possible to set up a boost controller enabling boost to be adjusted with the flip of a switch or with the push of a button. This would be much easier than changing pulleys on the supercharger. Excess boost could be vented to the atmosphere with a filter on it, maybe a turbo style blow-off valve and boost controller?? Any ideas? Anybody done it before? Thanks.

Uhh... Why not just turbo it?

Twin Screw superchargers create massive torque from 2000 rpm up. Also full boost comes right off idle. Turbos will have to spool up a bit before making full boost. I counted on using an big oil cooler for the engine and blower, and possibly intercooling (air-water) the air. Lots of plumming =(. Plus the turbo would mean a lot of custom fabrication.

With a properly sized modern turbo setup, lag isn't much of an issue. It could easily be spooled by 2000 rpm, plus they're just so much more efficient

The problem is there's no feasable way to do what you want with a supercharger. Mercedes had experimented with a magnetic clutch on the supercharger pulley that could turn the supercharger off until it was needed, that's the closest thing. I'm not sure but I think they scrapped the idea, although it's at least possible. But if you think a turbo is a lot of fabrication, I can't even imagine trying to build that.
