While looking at regular superchargers (say Weiand or BDS) used in "muscle" cars, I noticed that none of them seem to even have any sort of provision for a boost bypass valve. I've also noticed a lot of people that do the boost bypass "mod" to their L67/32 say they get better boost response at the loss of some fuel economy. I was wondering if the quicker boost response would increase even more if the boost bypass system was disabled completely (valve locked in the closed position obviously). Also, do any of the high end GTPs, m112 or m90 run with a disabled or blocked off boost bypass valve? Just curious if this would totally kill fuel mileage and also if someone does it, does it make the car have the slight blower "whine" at idle like the previously stated blowers w/o the boost bypass do.
