question about recirculating BOV into turbo
#26
Arrogant Wankeler
The problem with those setups is, the pre-turbo intake is at atmospheric pressure, the velocity of the air out of that pipe is not really going to be enough to make any measurable difference in the pressure the compressor inducer is seeing & thus work or energy it is imparting to the intake air or is imparted to it, the air will still partially recirculate turbo>BOV>intake while the excess goes through the engine (remembering the throttle is not completely sealed) & back out the intake. All of this is doing nothing more than heating the air up to higher than what the normal air feeding the turbo would be without a back feed from the BOV, & thus reducing your available power when the throttle opens again.
The fact is any of those issues as regards routing etc are immaterial & of no consequence in comparison to having an intake full of boost to get the engine & turbo accelerating hardest again after a throttle off.

I had sent an email to Synapse with pics of my proposed setup and this is the response I got...
As far as the signal line from your compressor goes, I think that is going to be just fine.
That recirculation setup will work just fine. But, the main thing that you'll want to keep in mind with where that tube discharges is to give it a at least a couple of inches of clearance away from the center of the velocity stack tapered inlet of the turbo. You'll also want to give it clearance from the sides of the velocity stack. We've actually been conducting quite a bit of testing on that lately and that is something you will want to look out for.
