I have read past posts and think that I got myself more confused. I have a gillis, heard that a blow off valve will prolong the life of the turbo because it keeps the air pressure from going back on the compressor , so I also got a blow off valve---can both be run together, I run a lot of boost but thought that the bov would help it out--am I wrong? Thanks a lot.
yeah it is fast, just a little slow getting back to the garage!🚓

Well, a by-pass valve is better, but yes, both can be run together, your gillis controls the amount of boost, and the BOV vents excess boost to atmosphere, thus keeping the pressure of your turbo.

Why wouldn't they be able to work together? Each type of valve serves an entirely different purpose: the gills valve controls boost by modulating when the WGA sees boost pressure, and the BOV / BPV vents the compressed air out of the IC / IC piping.

Why would a BPV be better than a BOV? They both do the same thing.

Ryan,
Lots of the 2.3T crowd run BOV. That being said, remember that ours run on a metered air system(the VAM, VAT & and BP) In theory metered air should stay in the system. so a BOV loses metered air and briefly changes the A/F. Does it matter? ...... does it matter what the best camshaft is?:

Ok, I follow that so whould I be better off just keeping the gillis valve and calling it a day? If I need to keep it in the system then I should not use the bov--correct?

A BOV and BPV aren't too hard to mount from what I've seen anyway, the BPV being a little harder between the two. I'd say go for it. I'm going BPV when I get the $.

Keith, If you have a BOV instead of a BPV, use it. Better to protect the turbo. Any disruption of A/F is extremely brief and occurs when it makes little difference. If anything the mixture goes briefly rich which won't hurt the engine

but with a BPV, isint its purpose to keep boost in the intake system, if you vent that away, does that take away from how much available power you have because the turbo has to produce that much air again?
left right left...the perfect shift...maybe i should call cadience when i bang the gears....

as long as I dont lose horsepower, that is what I is most important. I dont want to rob any power from the car.
