i recirculated my bov. i used parts from the alltrac and mr2 intakes to make something that would work in my car. its a little long, and takes a bunch of bends, but it works very well.

the benefits of recirculating the bov are HUGE! i really love it.

pros:
faster spool up
no more back fireing
smoother power
1st gear feels totally awesome.
great throttle response

cons:
no cool bov sound.


highly recomended for anyone with a bov on a swap. its one of those things were you dont know what youve been missing untill you try it.

thats awesome Art! Jay and Art, do you guys think that there is indeed a significant difference by recirulating the bov? Honestly i like the bov sound but i believe in performance over the ricey sound. Can you explain to me, what exactly happens when you recirculate it?

Any turbo car with an AFM/MAF for metering air runs best with a recirculated BOV/BPV. The ECU thinks that any air that is release from an vent-to-atmosphere BOV is going through the motor. This causes too much fuel to be injected into the motor and a rich condition that causes poor running.

I have a BOV that recirculate 50% of the air on my WRX to get rid of most of these problems and still get the 'cool' sound. (actually, the ECU on '03+ WRXs figures out VTA BOVs pretty well)

If you have a car that meters air based on a speed-density system (MAP sensor) then a VTA BOV doesn't matter. (I LOVE the HKS valve on my ST205 motor! Lol)
