I've ran mine since I can remember with a blocked off BOV.

With the ceramic turbo running 1bar I covered around 100,000km's on the rb20det, then pulled it out for the rb30det. Still in good nick. I went a VG30 which was good for another 50,000km's and was still fine when I pulled that off, the Garrett gt30 I now run still doesn't use a BOV.

The GT30r has covered around 40,000km's now. Damn time flies. :S

The bov is there for emission reasons. Without a bov look what it does to your afr's on and afm voltage as you come off the throttle which causes stalling, back fires and some times flamage. Another issues is the strain it puts on your joiners/clamps. I had to replace some with t-bolts.

The reason I went no bov is the stocker was for the part throttle drivability. No bov you grab the next gear and boost is just there. Without a bov it felt laggier on gear changes as I presume it takes longer to fill the FMIC and piping than it does to regain the 'slight' speed the compressor may loose due to pushing against a pressure source.

Shaun/Boostworx runs track cars with no bov, no issues related to no bov. I know of multiple high powered RB30et's without issues running no bov.

No more need to be said!!!!

Okay, old thread here. sorry, want to blank off my bov so I dont look like a fag when I drive around. Used search came up with this and a heap of old closed threaDs that seem to make it sound like IF u blank of ur bov it just makes ur car get that other gay flutter noise not silencing it completely. Is this correct?????

you own a turbo car but dont like the bov noise? have you got an aftermarket bov?

yes, if you block it off it will flutter.

Did have an aftermarket atmospheric one when I got the car which said LOOK AT ME, then swapped the mechanic who took it through regency for me for his stock one. But its still too loud oh well guess Ill just have to put up with it in exchange for a nice fast car.

The one that was on it also made a fluttery type sound when u gave it a rev.........I dont know fark all bout them though

you probably had an adjustable one, where you can stiffen to spring so it only vents a small amount of pressure and flutters the rest. if you have a pod, try fitting a stock airbox to quieten the induction noise and see how you go

Just out of curiosity.... everyone is saying use coke cans, mountain dew cans etc. Are they being used as blanking plates? Not entirely sure how its done.

I've got a 32 with an rb20 with an aftermarket BOV. Was just wondering what the deal is with making up blanking plates and what everyone has used.

As Damo has mentioned earlier. You cannot have a turbo car with a pod filter and not expect any induction noise at all. Even with the stock BOV it makes a loud woooosh sound. But if you block/blank it off all the pressure has to go somewhere and since the BOV is blocked it will just go back through the system hence why it makes the huge (in my case) flutter.

Totaly acceptable use of thread bump guys

Take your bov off grab a pen trace around it and cut coke can up a good pair of scissors is all that's needed

Presto spot on Steve. I have been using a coke can pretty much since i have ever owned the car lol

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
