Contour Enthusiasts Group Archives Forums Modifications Forced Induction for those of you with big $$$

i know i've read some papers on dual forced induction (there's a technical name, but i can't remember) but it's where you feed a the turbo with a supercharger (or vice versa) - the tuning is a nightmare but from what i remember it makes the whole setup very efficent but also requires tons of plumbing and cooling....

has anyone seen this type of setup?
