A bypass valve is designed to leak boost. I know this sounds stupid, but is true. Those of you that are complaining about leaking boost need to know that it is supposed to do that. It works like a spring. When the spring is fully compressed, it is completely open. As boost builds, it leaks in increments until max boost is achieved. Once full boost is achieved, the spring is completely compressed, therefore "blows off", whatever you wanna call it. By upgrading to the Bosch Sport 110, all you are essentially doing is replacing with a bpv with a stiffer spring. Meaning it hold more boost before it starts to leak.

The difference between a bypass valve and a blow off valve is this: A BLOWOFF valve HOLDS boost until max boost is achieved, and then PSSHHHHT! Thats why you get that noise.

With a Bypass valve, it DOES NOT HOLD boost, but rather releases little by little. Once max boost is achieved, all boost is released. That is why it takes so long to reach boost with the TRD blower. Because, while you are building boost, the bypass valve is slowly releasing some of it. Obviously it doesn't release as fast as it builds. But you get the picture of why its takes so long to reach max boost or even "FEEL" the boost.

The Bosch Sport 110 releases less boost than the stock bpv because of a stiffer spring. Max boost is achieved sooner. That is why it "FEELS" faster. It changes the power curve completely.

I hope this clears things up

And he says everyone says it so. I thought maybe i was uneducated about a BPV and I was the only person in the world that disagreed with him.

If you live near a Distrubitor name Factory Motor Parts go ask bout it..you have to special order it, but it's worth it..

Make sure the ending number is 110. 0280142110
