Aftermarket bov

I went with TurboSmarts Kompact series plumb back, rated for a ridiculous amount of boost and I don't draw attention, like a 4 min install.

If your ok with your car stalling at lights( not all cars do but some will depending on how you drive/ your idle) then not its not. I personally had to let my tune know that I had a bov so he could adjust my ilde aswell as I am still playing around with my IACV valve located on the rear of the plenum.

The MAF mesures the air that comes in in order to mesure the proper AFR. When the BOV releases, it releases air that has already been mesured in by the MAF. Releasing it to atmosphere only makes this mesured air exit the system without being mesured or telling the system that this air has left. Less air = richer mixture, since the system is expecting X amount but is actually receiving less air then expected.
The whole idea behind recirc is that it keeps this mesured air in the system at all times, by recirculating it after the MAF (since it has already been mesured).
Hope this makes sense.

This Synapse BOV -
If I had the choice at the time, I would have got this version of Synapse BOV with better flange design -

The car might stall when you are driving and shift into neutral (say if you are coming to a stop light), and it might idle rough.

My buddy used a pop bottle cap no joke, lol!

I got Blitz DD BOV on mine.. Idles great, sounds great and gas mileage is still the same.
(Mind you I have it on stock boost and the setting for my BOV is set to stock as well)

Aftermarket bov
Just wondering if I still need to leave the factory BOV in place or can I just block it off and use an atmospheric BOV in it's place. I got a Turbosmart vee port BOV with the car and would like to use it. This is on an RB20 btw.Tags: None
