Bov T'd off wg line?

[Hiitman]

I was talking with some buddies about my annoying bov flutter. One of them suggested T ing the like off the wg-compressor housing line. Has anyone ever tried this with much success?

For an MBC, you should never use the BOV. Always use a boost source close to the turbo compressor housing; either the compressor housing itself or the intercooler pipe.

Sorry I didn't specify what I was running. I'm just using the 23psi spring in my tial wg. What I was wondering was instead of running the bov to the intake manifold, would Ting it off the wg-compressor housing reduce bov flutter?

No, that would make the BOV not open at the correct time. The BOV signal needs to come from BEHIND the throttle plate so that when the throttle closes, the vacuum in the IM opens the valve. Putting the source in front of the throttle plate, when closed, will just send a boost signal, so you'll get surge.

If your BOV is adjustable, try adjusting it. If it's a Greddy, try taking out one of the springs.

Ok. That makes sense. It's a forge so it comes with different springs. I've tried the stiffest and the softest with little results. My gm map sensor is t'd off the im-bov line so I'll move that to one of the nipples on the tb and see if that helps at all.
