Does a BOV functions on a supercharger?

Yes, a Blow Off Valve can function on a supercharger. Basically a BOV is a surge valve. It prevents the excess air from going back into the supercharger once the throttle body closes. Most superchargers will come with a by pass valve which is almost identical to a BOV. They both are used to vent the excess air out of the discharge tube so you do not get compressor surge.

They are not 'basically' the same... they function differently.

You should NEVER use a BLOW off Valve on any supercharger, only use a surge valve. There is a difference, look it up. One is normally closed except when there is vacuum on the manifold at which point its open. Blow off valves will slowly damage any centrifugal and should only be used on a turbo system....

Call procharger if you like.

Terms are usually mis-used... simiar purpose but different approach.

You CAN use a blow off valve on a supercharger. Its all in how your system is set up to handle a BOV and how your BOV is set up(spring pressure) to handle the supercharger. Procharger was the place that told me to switch to a Blow off valve.

Can a blow off valve work on a supercharged car?

On a centrifugal supercharger(Paxton, vortech, procharger-yes. On a whipple /eaton- no because they are located between the throttle body and engine, BOV only work when the throttle body is between the supercharger and engine.

The term BOV means Board of Visitors in some instances, each operating in different places. The BOV in NC, primarily operates in NC State, as an advisor to the chancellor.


Can you put a BOV on a roots supercharger?

No, because BOV are used to relieve press surge that occurs when the throttle body is quickly closed and boost pressure spikes between it and the compressor outlet. Roots superchargers are between the throttle body and motor,so when the throttle closes it creates a "vacuum". They can be used with centrifugal blowers to allow a smaller pulley to be used, to get more mid range boost and bleed of the extra top end boost.

Turbosmart BOV's are designed to improve the performance of the turbocharger system. They will not usually damage a car engine.

sure, as long as the car has a turbocharger, and you source the vacuum/boost for the BOV from the intake manifold.


Where does a bov go on a rx7?

A BOV can basically go anywhere between the turbo and the intake manifold. It is usually after the intercooler (if you have one) as far as I know.


Can you put a blow of valve on a stock engine?

can you install it yes. will it benefit you on a non turbocharged or supercharged car? No. A BOV vents any pressure above atmospheric pressure (the increased pressure fed buy a turbo or supercharger ie boost) when the throttle body closes in order to keep the air from flowing back to the turbo or supercharger and potentially damaging it. in a NA (naturally aspirated) engine there is no increase in pressure above atmosphere.
