Electronic BOV
So the idea of electronic BOVs came up in conversation the other day.
The intent was for autocross type situations where the throttle is closed and reopened quickly.
With a typical BOV, the spike in vacuum will open the BOV. Pressure in the charge pipes is released needing to be recharged before boost pressure will be seen in the manifold again.
If the vacuum source can be controlled electronically, we could maintain pressure in the charge pipes for when the throttle is opened again without the compressor going into surge.
We have a full (unbuilt / untested) solution to the problem. My question is, even in autocross type situation where the immediate throttle response would be useful, would it be a reasonable modification to a standard BOV system?
We'll already be running MS, and have a second processor under the hood for other duties. So please, ignore time / money / development constraints.

We'll probably build it and test it anyway, just trying to get other peoples thoughts ahead of time. Sometimes we get a little crazy on the conceptual ideas. Making sure this ones not too over the top.
Correct. We'll maintain whatever charge pipe pressure possible w/o compressor surge. Not necessarily a preset number. If that pressure is exceeded, the BOV will open.

I know this maybe weird or different but my idea was instead of using a bov, is to the place the TB infront of the turbo intake and not run a bov.
This is reminesint of the F1 turbo days
If I were going to run a bov though I'd get this http://www.rx7store.net/product_p/sy...ff%20valve.htm
Mainly because their marketing and ideas won me over and so far it seems everyone is happy with it.
