On a better thought, With the wastegate or the mbc it would only operate like a normal dump-full boost. Im talking like buying one with a dump and somehow cutting the dump pipe somewhere right at the housing and making something that would cap it off or block it, but have it where you can hook it to the dump pipe exhaust quickly. Then you could roll around quietly with it recirulating and then just hook it up in a minute when you want to fuck around................I think I might try this, anyone think just the little bit of turbulence from cutting the dump pipe like 3/4 of an inch from the housing? It would have to be at least that far down to be able to reconnect it and cap it. Just wondering with the cons could be like that.
