Why the hell would you want backpressure? This is such a horrible myth it needs to stop. Backpressure is not something you want.

what would be cool is have that on the intake pipe to bypass the turbo and intercooler piping so the car will not have boost lag.

Once the turbo spools.. the intake valve closes and the exhaust valve opens.

I dont get what your trying to say here...how do you bypass the turbo and expect any power? I think im missing something. If the exhaust is closed, your turbo cant spool, and your car will probably explode.
