i ordered the greddy type rs bov. i know i know.....but what is the difference from vta and recirculating and do recirclating bovs still whooosh?? the greddy type rs is recirculating riiight?? from evo moto install section it looked like it. sorry i know most of you are tired of these questions but help me out thanks

 

You need to have a seperate adapter to get the RS to recirculate. You unscrew the blue horn section and replace it with a cylindrical blue piece to reciruclate

 

if you do this it still whooshes??? and this special flange along with the single spring mod fixes stalling???

 

I had no problems with stalling when I had the RS, even with both springs still in place. It will depend on each individual car, some like one spring, some like two. Just recirculate it to keep hassles to a minimum. YOu will barely hear your BOV when it recirculates.
