Bov's & Positioning... Does It Make Any Difference?

[4drftn]

hi, i was wondering if the position of the bov makes a difference in performance or running of the vehicle... i currently have an apexi twin chamber bov (on crossover) and was going to replace it with a turbosmart supersonic (without adaptor for crossover) which has a weld on piece.

how well do they operate (performance wise)?

would it work best if i had an adaptor?

will it make a difference if its on the intercooler piping?

how much boost should i run for maximum sound potential?

maybe a more recommended type of bov....

how well does your current bov operate, and where it is located?

any info will help me and hopefully help others on this issue...

cheers

whats wrong with the stock one?

it works and its simple, no thinking required

how much psi can a stock bov take though?

location can make a small difference to response. you want it as close to the throttle body as possible. this makes it so that when you lift off all the air keeps going in the direction it already was. only the air from the throttle body to the bov has to turn around. if it is close to the turbo then when you lift off all that air after it has to go in the opposite direction it was and then when you step on the gas again it has to change directions again.

also by having it after the intercooler, if you step on the gas before all the air has been released you have nice cold air ready and waiting to go into the motor.

which is another reason why recirculating bovs are good. all that nice cold air gets directed back into the intake, so you have nice cold air going into the turbo.

excellent, makes a lot of sence when you put it that way... cheers
