has anyone else seen this done? it looks like ssdurango is doing it on his propane setup, is there any benifits/hurt by doing that? i have an eaton m90 sitting on a shelf doing nothing, would be nice to be able to use it without having to hackup my intake manifolds :P

Most OEM applications put the TB before the supercharger. You'd only need a BOV if you put the TB after the SC. The bypass valve is only there to reduce the power robbed by the supercharger at low throttle. It allows the air to bypass the supercharger and go straight to the engine.1995 Grand Am SE

I had my Throttle body/carb before the supercharger last year. But I've switched them around this year. I haven't drove it yet but I don't think I'll need a Blow off valve because superchargers slow down with the crankshaft in between shifts where as a turbo would stay spooled up. Make sense to you ForcedFirebird? And another way of looking at the bypass valve is that it recirculates the air without building pressure until you need it.
Is your M90 ford or Gm style. I'm using the 94-95 thunderbird style.

When the boost bypass is engaged the S/C basically free wheels since it's not building boost.sigpic New 2010 project (click image)

I'm still using the ford bypass valve, so any boost backing up in the intake pipes would be able to flow back out the filter if it really had to. I don't see any way of incorporating a bypass AND a BOV because the bypass valve snaps open when the engine is under vacuum. It would be sweet if I could because I really love that sound.

I think the buicks had Eaton M62s. Also ford M90s are flipped upside down so the boost comes out the top so they can use air-to-air intercoolers

but most of the RWD guys just flip the manifolds around and make a custom Y-pipe to go into their turbo's (and pray for nothing getting in the way of the routing )
