Why you say that? I heard on a caliber SRT-4 and the sound is great. Problem was that he was spiking so much boost the BOV actually started letting out early. At like 3 grand he spiked 20lb's lets say, and the HKS would go PS PS PS PS PS and then at 3500 it would stop fluttering and hold till redline.
But since HKS are Piston operated, they make an upgraded purple piston to handle more PSI then the stock one. Its cheap too. He just ordered that to handle his boost and stop the flutter.
My question about my Greddy is, when I 1st start my car I get compressor surge under normal driving when everything is cold. I mean i will be driving down my block and it will be surging at every shift no matter what the boost. As soon as things warm up it stop and will blow off like normal. Is this normal? and why the hell would that happen. I sprayed some WD-40 inside the BOV on the piece that raises and lowers to let the air out, seemed to help a tad bit and when it blows off you hear it seal real nice when its done, but WD-40 only lasts so long b4 you need more

theres a new HKS coming out, i hear it is much much better than the previous 2, i would try that one.
the other 2 are known to leak under heavy load.
y do you hook it up at the track and not for daily driving? your car doesnt react to the non-recirc?

My car runs EXACTLY the same vented as it does recirced. I mean I was very suprised. Not 1 Check engine light, spool time isnt any different, sound is awsome, had it tuned and A/F was fine, no knock. everything is straight. I really dont need to recirc at all but I went ahead and bought the hose and cut it to size just for the option if I wanted to
evos are made to run recirced is y i ask. you pop off the recirc hose on our BOVs and the car doesnt want to idle below 1000rpm.
cool ****. non-recirced is effin loud!

I have adjusted the spring so many times that I dont remember what that was set in the video at and what it is now. That vid was when I 1st got that biznitch on. I know its soft now though, but I mean comeon, that sound gives me wood

Its as easy as never installing any recirc tubing lol. BOV's come ready out of the box to vent atmospherically. To recirc you need to weld a nipple on the intake, buy a recirc adapter for the BOV usually, find heater hose that fits, and worm drive clamp it on. If you just want the BOV, just weld the BOV flange on your charge pipes, put the BOV on it. POOF. Would suggest a block off plate for your stock BPV though. Get one at
