I had mine installed the same time I did a handful of other things so I was getting retuned anyways, But I would think I same adjustment would be needed since this is pre-MAF location.

EVOHUNTER, did you need to get your ECU re-tuned or did you just tinker with the knob on the top of the BPV until it was venting and idle was OK.

Doesn't the BPV suck in unfiltered air as well?

Did you check to make sure the air horn and bypass nipple were on the right sides of the valve? they could have sent it with them switched. the lower port should be the recirc and the upper port should be the vent. after that you may have to set the spring tension on the cap.

I did not check it out yet. My tuner installed everything for me. No garage and time to do the work.

Is it correctly setup from the posted at the top of the page? I can check the BPV and see if it matches. Didn't know that the BPV could be installed incorrectly or put together incorrectly by Turbosmart.

When the setting was to stiff, it would almost shutter the bypass valve, and almost surge back towards the blower, I could clearly hear it. I loosened mine up and that went away.

Hey I just vented mine out sounds awesome! I also have the same afr numbers. But I wonder if I'm loosing boost this way?

I wonder how it will affect the car during WOT runs, between quick shifts when the BPV opens and shuts. Hope it doesn't hurt the engine.

How is it set? Halfway?

I tightn it all the way then I back it out a half. At about 7k rpm my afr was at 10.9. But I did notice at high boost and around 7500 rpm you could hear it. So how can that not be loosing boost? That's my question? If it's venting when your stepping on it then that would mean that your loosing right? Anybody chime in if you can! Guess I'm confused.

If you hear the air escaping from the BPV while you are on the throttle then it is definitely losing boost. It's only suppose to release pressure when you left off the gas and there is a backup of pressure.

ANMVQ 06-06-2014 08:46 AM

Yea for sure, I wasn't losing any with mine, 11 PSI right away and 12PSI upper RPMS.

FYI.

I fitted a Spec R Type B twin piston blow off valve which is a straight swap for the Stillen supplied one. Works perfect, perfect idle and sounds great.

1slow370 06-09-2014 06:22 PM

a supercharger bypass vavle is usually open at idle and low load conditions as well when pressure in the manifold is a set amount lower than pressure in the pipe. so if you give it a fair amount of throttle the valve will shut and build boost until you you close the throttle and the pressure difference between the pipe and the manifold rises. By changing the spring or turning the cap you adjust at what pressure difference this happens at.

1slow370 06-09-2014 06:30 PM

it looks right here is the manual with info on setting the cap http://www.turbosmartusa.com/wp-cont...t_DualPort.pdf

Did you guys ever find the perfect amount of turns on the BOV ??
I went all the way in and 1 turn out and so far so good

StillenZ84 03-03-2015 10:04 PM

It took me quite awhile to find the right setting. I ended up turning it all the way soft and out about 2 turns. You just really have to find the setting where when you rev the engine is basically comes right back to idle without dipping below or bogging down a little. If it is set to hard then your RPMs will come down way to slow.

Looking for a new BOV and am looking for sound more than anything, without having the car run like poop of course. But do any of this BOV being talked about sound anything like a HKS SSQV, had one on my 2G Eclipse years ago and loved it.

Hi,

so the BOV sounds in the open Version :tup:

Unfortunately, I'm waiting too! :stirthepot::stirthepot:

Always the same .... if you do not do it yourself!
