The BOV should remain closed still as long as the upper port is still connected to its pressure source.

 

We have done a few. If done correctly all works fine.

HKS used both times.

Okay the faulty BOV was one of only a few reasons why my car was acting up....I have seen a few others running that BOV and never had a problem....okay Mike can you PM me on how you set up the SSQV? I can send you whatever piping you need to get it to work....I am a huge fan of the way the raptor sounds too.....another major reason for me switching the BOSCH plastic unit is due to past experiences...I used to have a worked 2001 SAAB Viggen and those damn BOSCH units used to leak over time....so I figured I'd replace it with something that sounds nice at the same time.

 

might want to check into this one - "...designed to replace the 1 inch (25mm) Bosch Bypass Valve used in most Volkswagen and Audi applications..." It still recirculates and looks like it might fit in the original location.

Thanx dude...that ranks high on my list now....anyone have experience with the APS? It's between the TurboXS now and a Forge unit....I don't mind keeping a recirc valve but would like a little more volume from it.
