I know they do different jobs but I have never seen one on an FD(POV that is). Most people are using two BOV's but would it be a good idea to use one of each? Just wondering if anybody out there has some feedback on this.

 

POV are used when the boost gets above a certain level. We are not using 2 BOV's. One is a Charge Relief Valve and is used to vent the secondary boost under prespool. Replacing one of these with a POV could cause turbo damage.

 

I should have been more specific.....I meant most people with single turbo upgrades use two aftermarket BOV's.

 

Aah. I see. I remember reading something on here about the effectiveness of a POV. Try searching and see if you can dig up the thread.
