Simple BOV Question.
#27
Respecognize!
i love threads about therories, especially this stuff. Where is that thread from last week that had graphs and charts showing the pressure waves generated in the charge pipe?
the position of a BOV (pop-off, diverter, whatever) is all so damn debated, hell even the idea of HAVING one at all usually comes up on here.
but as for the above, i was noting the use of "preformance". The position's effect on the preformance of the engine will be negligible.

I believe, he was running sequential twins without the CRV as well.

I think, primarily from my experiences, the problem is that under certain cruise conditions, the turbo sees enough exhaust gas pressure to build boost in the pre-throttle ducting, but the throttle position is still so low (like 10-15hp worth) that you're still under manifold vacuum. The end result is that you're working the turbo anyway, and it sounds like you're driving a hairdryer or a dentist's drill or something. With a blowoff valve, the manifold vacuum would be holding the valve open, and the turbo would just be free-spinning instead of being under load, so you wouldn't get the turbine noises.
