When you run boost from your blower in to an turbocharger it is okay,you can use the couplers, because they will expand, BUT, when turbo SPOOLS UP, it starts SUCKING more air than supercharger can supply. The turbocharger will create a HIGH VACUUM, which will suck these couplers and then these sucked couplers will close the air flow .Thats why he added a bypass valve, a throttle body from a BMW. The SC will basically be freewheeling with no pressure differential across it.
Quote:To prevent all these things, you need to install a ONE WAY VALVE, which will open by a vacuum created by a turbocharger.That would be very inefficient and potentially overspeed the turbo. Making it pull a vacuum will drastically increase the pressure ratio to make boost pressure which heats the air, makes the turbo work harder (high exhaust backpressure) and puts a heavy load on the thrust bearing.
Quote:Also, i removed my THROTTLE plate from intake manifold and made a custom one in the back of the supercharger.So the entire system (SC/turbo/intercooler/manifold) is under throttled vacuum? Doesn't that cause really funky part-throttle performance?
