Oh i see thanks for explaining that i have always wondered how that worked it litterally moves the boosted air right back to infront of the turbo inlet. I will be making a plate up today ill let you guys know how it goes. I put some good mileage on it yesterday and it performed awsome.

Ok stay tuned for some pictures but i have finally did it! I dont have it plumb into the air intake yet but just even venting into the atmosphere my car runs exactly the same no problems what so ever! It holds boost fine and vacuum doesnt leak at all my biggest fear was flutter but i dont have any o...

Haha thank you for your help i will be tigging it up today and will post pictures aswell as how it performed.

I just thought you would want the maf to register the air that is going into it so it can account for it and make any changes. Where does the factory cbv dump the air?

The reason im doing it is cause im running a manual boost controller and already getting flutter from the stock cbv. With a bigger turbo injectors and some custom tuning i am hoping to see around 300 hp. The factory cbv has been known to fail under high boost conditions i dont see a problem replacin...

Ok so i am in the process of putting a recirculation valve on my 1997 850 t5. I was just wondering where the best place to put the outlet for the discharged air in the intake pipe before the mass airflow sensor or after. I know the maf on these vehicles are picky and i have heard on other cars guy d...

Im going to be deleting my cbv and installing a blow off in the short future regardless so i will see if it makes a difference. The only thing i can think of is when the boost comes on to hard it erratically opens for some unknown reason? Weak spring? diaphram? My cbv is healthy i believe it works g...

I recently put a manual boost controller in my 1997 850 t5 wagon i have it set to 13-15 psi and it works awsome. I have encountered a problem though if you slightly ease into it. it accelerates just fine but if you out the pedal down and floor it it will go but it for a split second it falls right o...

All right that did it thank you tryingbe. I turned it all the way closed and did even less then a quater turn now i got a comfortable 13 pounds of boost wide open. The car was fast before it is a monster now. Just waiting for my vag com cable to get here to convert the car to motronic 4.4 and we wil...

Yet if i blow into the mbc while turning it i can feel it working it will regulate the air going through it its suck a simple design i cant see it failing.
