It's actually a trade secret for a rather large well-known company, though I won't go into details. Definitely not something you'll see on the streets!

I think the most difficult part of it all is venting or "turning off" the superchager at a set rpm/boost when the turbo kicks in. Someday I plan to try it out on a v8 setup....just imagine the looks of seeing a blower and then hearing the singing of the turbo. That'd be a head turner for sure, haha!
