BOV Placement.

So whats the virdict, before the cooler or after??

Daune what you think??

Honestly on street cars with the boost levels we run I think either way is pretty much the same. I will test it on the car I am busy with but I dont expect to see much difference.

You may see a difference on a road race car or drift car but most people flat shift when drag racing so the dump valve never opens anyway.

And the possition on the pipe, where and how far from the cooler?? I will make it a smooth exit and everything so the flow is good.

i reckon put it where the air speed is lowest or the turbulence highest so it wont affect the airflow that much.
From a intercooler efficiency point of view bevfore the cooler is better but from a flow restriction point of view I reckon after the cooler is better. The pipe ID is bigger and the air speed is lower and I reckon at the intercooler outlet as the turbulence is highes there.

You could play for weeks with different positions and come up with no proper conclusion on a road car.

I would suggest just before the throttle body.

basically I think we are all stressing with the small stuff.

My Recirculation Valve is on the hot pipe because of piping constraints.
I know its not the best but it woks and I don't have the time or am I willing to waste the money to move it...
