And that my friends, is why bypass valves exist.I personally haven't seen a single person accomplish this feat successfully. The main reason being due to the following:
Turbos are regulated by air flow and will push the air into the supercharger that is regulated by the belt. This can cause massive damage to the supercharger and your engine. Further, if the setup is not exact, if the supercharger spools faster than the turbo you use, then the suction would spool the turbo as well causing the exhaust side to pull air from the head causing another set of problems.
I watched a guy try this on his Integra with a very well built engine and fried just about everything under his hood. The turbo even had to be rebuilt while the supercharger wasn't even reusable after snapping the spin rod.
Be prepared for the worst.
