The wheels aren't designed to withstand that kind of impulse. This is where the bov comes in. As soon as vacuum is applied the bov opens the charge pipe, letting the pressurized air vent instead of running back through the turbo.

Okay, no bov with an open pipe is just as bad. You're spinning the turbo up and the wastegate is never seeing boost because there's a big ------- hole in the pipe. Now you have a turbo that keeps spooling and spooling and there's no pressure, so it blows up. Either way you get a bomb.

Re: turbo civic runs like ---- no drivabilaty please help me!
Um.. what? You need to go back to first grade to learn how to write in an intelligible way. Your exhaust is still pumping out air whether the turbo is hooked up or not, correct? Well the turbo spins with nothing to control this spinning (since there's no pressure to tell the wg to open). So potentially the turbo could spin up to 2x what it was designed to, because there's no way of controlling the exhaust flow. The wg never sees the boost because there's no pressure being built. The cycle is not broken as you put it. The only thing broken about it is there's no pressure in the pipes so therefore the amount of exhaust gases is less, but there is still plenty to spin the turbo uncontrollably, which will happen because the wg will never see boost.
