Bypass valve & Blowoff valve

Just have a quick question.....A bypass valve and a blowoff valve are these the same thing?I know my Vortech kit has a bypass valve , does this mean that it will have that psssssssssssst noise or is that a turbo thing?
oh yea , what is a wastegate? LMAO sorry I'M not the sharpest tool in the shed.....when it comes to my Mustang

Re: Bypass valve & Blowoff valve

lol its easier to think of it this way

"Same concept, different applications"

its basically a vacuum controlled valve that re-routes a gas somewhere else. Wastegates are designed a bit differently than a blowoff or bypass valve, as they (wastegates) operate at far far higher temperatures than a blowoff or boost bypass valve.

Re: Bypass valve & Blowoff valve

ive never seen or heard one in person so i have the slightest. i will agree with you however, after having a turbo car before, the bov gets annoying after a week or two.

id venture to say that because boost is based on engine speed on a centri, that you likely wont hit boost in the daily commute, or wont be enough to be any loud sort of sound.

Re: Bypass valve & Blowoff valve

Under normal driving when engine vaum is high there is no boost. The by pass valve is open . Under load when the engine vacum drops the bypass valve closes and voila you have boost. Normal driving you don't notice anything at all

Re: Bypass valve & Blowoff valve

You dont see any sort of valve to drop boost on supercharged cars usually, why is this?
