Just had an idea of installing a T valve inline to my race valve. I could close the valve, cut the vac. And my race valve would shut, forcing the red race valve which vents to atmosphere now blow into the motor. On paper this would allow me to have boost earlier. How do you guys think this would work and how would it effect my tune. It would be like a turbo boost elbow or waste gate.

The only time the valve is open is partial throttle, wide open the valve is shut anyways. The only way to get more boost is by pullies. If what your trying to say is have ur valve shut all the time your gonna back feed your head unit, get compressor surge, and damage it.

Well saying I could adjust how much the valve is open. And when. I def. Don't want to back feed. Im aware how to get more boost. Thinking how I can get existing boost under 2800rpms.

Would the fact that the belt running the charger forward permanently prevent back spin?

I'm sure if I kept it fully closed and prevented air escape. But if I tweaked it some and close it partially it would still open when off throttle and shifts

What he's saying is that at WOT there is zero vacuum, so whether you're WOT at 1k or 6k you still have zero vacuum therefore your valve is closed.

The only way to make more boost is to spin the compressor wheel faster.

Gotcha. Makes sense. Thanks guys
