My car came with a GReddy BOV it has 2 nipples on the top but nothing was connected. I was wondering if someone had a diagram or a picture to show where i need to hook the hoses up to, and what size hoses.

Thanks

Top goes to a vac source (intake after turbo). The bottom is not needed.

If you don't know....


DON'T POST!!!

The top nipple on most BOV's goes to a vacuum source after the throttle body.

The bottom nipple goes before the throttle body to make the BOV act as a "pop off" valve, or simply just not used at all.

HKS Adjustable Pop-Off Valves provide secondary overboost protection in the event of wastegate malfunction or failure. These valves simply pop open at a preset amount of boost pressure allowing excess boost to blow off to the atmosphere

A pop off valve will open @ "X" boost pressure to save the engine from over boosting.

Also, the top on that greddy BOV should be for adjustment.

It should not stall in traffic unless you boost.

helps the car not stall out due to some air being recirced back instead of it all blowing off. thats my understanding.

Nice setup on the BOV jtran8, that's how it's suppost to be done when you still use an AFM ;). If only others would do that and not gripe about their cars stalling and/or backfiring...
