Forge BOV review
Az3ar,
It's deffinetly not anything remotely resembling compressor surging. It's really just an inconsistent responce from the valve during the transition from vacuum to boost that causes the hesitation.
It's somewhat a normal occurance on almost all turbocharged cars but it is esspecially pronounced on the Evo.
It's only a driveability concern, not a reliability concern.

Is there a way for you allow the partial throttle lifts to vent to the atmosphere? I believe that this small deviation in air release won't cause too much of a rich condition or stalling.
Another idea, as seen on the 1G BOV, is to have a small vent tube that recirculates the partial throttle deviations.
Hope this helps

That's the idea, and the general concept behind the OEM valve as well, but the problem is incorporating those features into an aftermarket valve made out of billet and utilizing other key features of our designs.
We want to create something uniquely our own that retains 100% of the functionality and reliability.
That's what I'm still trying to figure out with the tremendous help of our development staff in the UK.

I get the hesitation only on 5th gear under heavy load once i let off the gas slowly. Its strong hesitation and you can feel the whole car jerking. It happenes on 10 psi and above. If I let off the gas all at once its all good. I do boost up to 30 psi on race gas and around 24~ 23 on pump.
Thank you
Thank you
