Without it it's not needed. it's to vent excess boost.
They got it to work on a bike...
No
no, bov are mounted on turbos
cut a hole in your air filter and then mount it securely and your good to go make sure you use elmers school only cause it will secure it tightly but able to take off in the future also buy an hks ssqvbov cause its the only one that will work On a non turbo, there is no pressure to "blow off". So a blow off valve would not do anything.
Stick with the BPV (by pass valve as a BOV (blow off valve) will mess up the air/fuel mixture since the WRX's MAF (mass air sensor) is before the turbo. It isn't worth the tuning headaches and would only really work properly if the MAF sensor is moved "after" the turbo/BOV. If you still want a BOV, The Hks unit is one of the more popular, but Tial, Blitz, Greddy, Turbo XS also make good units.
The turbo blow off valve works by:If the throttle returns to idle while at high boost the valve opens and relives the pressure preventing turbo damage and speeding boost recovery time.This is done by use of a over pressure sensorOr by use of a throttle position and boost pressure sensor working together.
It doesn't
The same way any other whistle would work. You blow and it makes sound. Where here your exhaust does the blowing
yes some turbos come with out a waste gate (none waste gated turbo)
No. A blow dryer sucks in air, heat/cools it, then blows it back out again. Without atmosphere, there is no air, and without air, there is no blow dryer.
yes it will work the cold air intake will produce enough back pressure thus causing a pssshhhh sound for the blow off valve if u hook it up inside the cold air intake system you will hear your bov working will not work on the out side of the C.I.A
If the car is the same as in it came out of a non-turbo and your putting it in a non-turbo it will work but if it came out of a non-turbo and your putting it in a turbo then it won't work. If it came out of a turbo and your putting it in a non-turbo it won't work. If it came out of a turbo and your putting in a turbo then it will work.
