hey guys,

Just fitted my universal hks ssqv onto an adaptor that I got made up for me. Having many issues, car idles horrible, up and down like crazy from like 100 to 1000 rpm non stop, engine struggles and vibrates weird, while its doing that black smoke comes out of the exhaust, If i put my hand on the bov where it blows the air out the rev thing stabilizes but as soon as you drive again its doing it all again. I have blocked off the plumback pipe with a bottle cap, is that good enough? It had an O ring that i purchased from US which is too small and doesnt hold it tight so I have put a larger O ring to make it all sit firm yet under mild acceleration you can hear the bov wooshing(leaking air right?)

Since then I have out my stock bov back on and now my car has misfires on high rpm

Can anyone help me with this?

thanks heaps

yer i had the same problem...i just took it off and pout the stocker back on. thing is i noticed that the aftermarket bov didnt properly close when the butterfly was closed, like i revv the motor, it opens but closes slowly but not fully...im assuming its a faulty bov or i have a vaccum leak where I HAVE NO CLUE!!!

yea it seems to leak, but thing is i put the stocker back on and now my car misfores on high rpm when flat out, would it be coz the black smoke covered the plugs and they are no good? or is it coil packs which i doubt could be damaged by playing around with a bov.

2nd one I've seen play up... The valve c*cks sideways and gets jamed open = leak...

You should be able to close and you will hear it pop back into its place. It will work perfectly intil it gets jamed again.

Yeah as other said change plugs, because when the BOV is leaking its the same as intercooler pipe blown off and AFM reads all this Air coming in but its not actually getting into the engine... rich rich mixtures.

yeah i have a genuwine universal hks ssqv bov, im just gonna sell this one and buy a skyline specific hks ssqv which are not meant to have adjustment screw, is that right?

the rich mixtures must have stuffed my plugs, i'll replace the plugs on monday and reset my ecu and see how it goes.

Btw i had the car running with this dodgey bov for about 20 mins blowing black smoke while it was reving like crazy, would it damage my airflow meter by any chance?

wouldnt hurt to clean the afm anyway with some throttle body cleaner its not hard to do. im not sure about the car specific model having no adjustment screw, because all cars vary, like say you might have a standard car and it works fine on it and then you might have the same model car but with 300kw it want hold boost there or it will cause excess flutter/not open on the stanard car. i reckon the best bov you can get it the new greddy type rs it can be plumb back aswell. :P

how do you clean the airflow meter? pull it apart or something?

Why do you say the greddy type rs is the best?

what sound does it make? is it like a unique sound or the usual pccchhh! ?

Better yet, keep your original BOV and eliminate all your problems.

Personally id rather my car run properly then have a full sick phhhs phss whistle whistle where are the chicks? sound.

My car came with a turbo smart plum back bov but if i didnt i wouldnt have bothered spending that much to replace something that already works just fine.

thats true, but once you boost your car the stock bov doesnt hold boost and leak bad, so you have to have something aftermarket on a modded car

Well if you NEED to, go a plum back dude, i havnt had a problem with my bov at all, no idling issues or stalling.

If you have the standard ECU definately go plumb back.

yea thats my plan, either plumback the hks ssqv or get this greddy type RS and plumb it back

the greddy rs you can either plumb back or atmo, better than other bovs that do both.

you clean the afm with throttle body cleaner just spray it let it dry and then spray it again and it takes the dirt off pretty easy!

go to nengun for the greddy type rs they have cheap prices and vechile specific models.

Youll still be able to hear them if you plumb them back as well, so you can get the best of both worlds (that is if you like the noise of a bov)

      Borg Warner EFR Series Turbo's V 2.0

      Thanks for the quick replies guys its appreciated. A small extension was welded onto the standard 6boost external gate pipe which you can see where the pipe goes from black to stainless just below and to the right of the rear housing in the first picture. Overall I would say the flow is pretty good other than 6boosts choice to come straight off the collector at a decent angle.. Not sure why I went with two valves, I originally replaced the stock twin bovs with the GFB when I had the twins on. When I purchased the EFR it came with the Turbosmart Kompact BOV so I figured that would be a better option than the stock EFR Bov. I don't believe the Turbosmart BOV is adjustable? When I get the spike and then sudden dip in boost pressure, the turbo speed does drop as well. Stock head size wise however I believe it has Neo Turbo springs and a Neo Turbo intake camshaft and an aftermarket exhaust camshaft in the vicinity of 260 degrees. We didn't try a different MAC valve, we tried two different ways of plumbing it and we also tried removing the mac valve entirely and just having the boost source from the turbo directly connected to the wastegate and it still spiked / dropped and exhibited the same behaviour. Standard R33 GTR 5 speed tansmission. I'm running a Haltech Elite 2500 and can provide some logs if you. I understand what you're saying in that it looks like an auto plot however no, it's still a manual and it just has a lot of torque down low, for all intents and purposes it's a very impressive street car. I've attached a photo of the quickbitz dyno plot which was when the only difference is I was running -5 twin turbos with a mac valve. As you can see theres a decent dip in AFRs between 125kmh and 135kmh. Our problem now is not that the AFRs are dropping, just the boost pressure is dropping, however it is evident in the same RPM range of the map, coincidentally or not.

      What transmission are you running?  It's a bit tricky with the scaling, but at face value the power "curve" looks more like a "line" which is a bit odd... basically a lot more like a dyno plot I'd expect with a highish (compared to a factory auto) stall torque converter type setup. If this is running an auto then this kind of boost control challenge is definitely a thing, the rpm scale on the dyno doesn't reflect what the engine is actually doing (unless the dyno has access to the engine's ACTUAL speed electronically) and what you'll get is a big rpm flare up as the engine torque launches past the converter pump's ability to resist torque at that rpm, then as the converter starts picking up rpm it will kinda even out again and the engine rpm will pick up more steadily. The trick with this "flare up" is if it's kinda near the boost threshold for the turbo then the engine's airflow requirements to maintain the previous boost level will outrun the turbo's ability to supply that boost - so you end up with a natural flattening off, if not dip when that happens.   If you are running closed loop, or even tune the "feed forward" wastegate duty cycle to deal with that rpm spike then when the engine starts settling to a more typical climb you'll actually have a situation where the gate is "too closed" and boost will run away for a bit, then have to pull down again.      It's not trivial to get this perfect as most boost control systems are generally expecting more predictable engine rpm rates of change, but if you *know* that's whats going on then you can at least "accept your fate" and realise getting that area perfect is kinda chasing your tail a bit, and assume that if the rest is working sensibly and the spike/dip isn't completely uncontrolled then you should be good. Sorry if I've gone off on a tangent, but the dyno plot and boost control behaviour look a LOT like what I've seen tuning autos in the past. What ECU are you running? Could possibly be convinced into looking at logs if I get too bored this weekend haha.

      A few things that seem a bit off here. - why is there 2 BOV’s?  - the turbo smart BOV on the compressor housing, is it turned up ALL the way? I have seen this become an issue on old man Pete’s car. It would push open and recirc, turbo speed would rise and the boost pressure would do weird things. - stock head? Does that include springs? - tried a different MAC valve? Is it plumbed correctly?

      Photo of manifold showing gate location? I mean, it's 6Boost, so we probably shouldn't be worrying, but always wroth knowing what the layout is. Plumbed back to atmosphere? Or into the dump?
