Stock BOV mod

Could you take off the stock rubbler re-circulate hose off the BOV and plug it, so that the stock BOV open atmosphere?

Don't.

The recirculating valve vents to the intake to keep the turbo running at 0 load. This way during shifts you dont need to respool the turbo. By venting to the atmostphere you will run slower, and make some noise. Speed, or some noise? Your choice...

Thank you for that, I had no clue. So if I was to put a BOV on my GN (auto) wich dosnt have one, it should have a recirculating hose?

let me get something straight, your saying aftermarket bovs, one being open atmosphere would slow down the spool time of the turbo on any turbo charged car?

when your aftermarket bov is 100% to atmosphere, it means 0% doesnt go back into the turbo to start up the spool again. the stock bypass valve recirculates, so inbetween shifts, some of it goes back into the turbo

It recirculates into the intake track. It doesn't go into the turbo. Only exhaust gas spins a the turbo. With the stock power levels and even a little higher the stock bov is fine. With a lot of power therefore a lot of air to vent you need a bigger bov or you'll get compressor surge which is trying to stop your turbo dead then push it backwards.

oh god.. just leave the damn thing its got the recirculation hose for a reason. if you really want to get that sound just put a damn speaker under your hood it would be smarter in my opinion otherwise ur car wont run as smooth.

Worxtuning BOV is a good compromise bmetween drivability and sound.

If you want to get the BOV route, get the "loud ring" worxtuning BOV. You can adjust it to recirculate as much or as little as you want. After playing around with the settings, you can definately notice more lag between shifts at 100% Atmospheric setting vs. fully closed. I keep mine at 25% atmospheric 75% recirc.
