Choosing the right BOV

[Baz]

I'm a first time buyer of a turbo car (buying a R32 GTS-T) and am looking for a few beginning upgrades for my car. As a BOV seems to be one of the most popular upgrades for a turbo car I just want to make sure I buy the right one and be happy with it.

I would like to hopefully hear from some people about there experiences with there BOV's from the various dramas/problems they may have had or the satisfaction they got from it. From what I have read the HKS SSQ BOV seems to be the best but it is also bloody pricy. But with so many other manufactures such as GREDDY, Turbosmart and other brands there are so much to choose from. Also I would like to know the pro's/con's of plumback systems.

All comments would be greatly appreciated,

Cheers.

I heard the GFB (Go Fast Bits) range of BOV's are good. I run a Blitz BOV old type and i like it. Requires a bit of fiddling to get right....

I found i had to completely remove the stock bov, block off the hole and the return pipe and it worked a treat from there, just a few play's with the adjuistment screw..... and PCHHHHTT!!!

i have a hks ssq with pumb back mod for sale - pm me if you are interested after your research

[paulr33]

keep the stock one, focus your $$$ on exhaust, air filter (hi flow panel filter or pod with cold air intake kit), boost controller etc. the stock bov is fine

[yogi000]

i'm wih paulr33, the stock one does the job, change it only if it starts to fail.

but if your after that blow off sound.....go for it.

agree'd with the above 2, but when it comes to change the bov, i have the GFB Hybrid, which is really great, just got the adapter plate to where the stock one bolts on, and its part atmospheric and part plumback to help with the air/fuel ratios etc, and helps it not stall, without this, and not tuned of course the car was stalling every 2 seconds...

cheers...ben.

Is that the main reason the dual venting ( plumb/atmo ) BOVs were made for? For people with AFMs so they dont mess up stuff with the afm but still get to hear the atmo venting noise?

Or is there another benifit?

I am also in the market for a new BOV as I have a shitty plastic bosch one and its not coping with my boost levels.

I dont have an AFM so thats not an issue but I want a plumb back one and just wondered if there was any advantage in getting a dual port one or not?

I dont want to have an old lady scaring "PSSCCHHH"

[2BNVS]

yep thats the reason, mine is still as loud as my mates turbosmart type 3 and he runs 17psi so its not like its quiet at all, just helps with the mixtures

A question though. Is the factory BOV capable of handling high boost levels or once it reaches a certain boost level it begins leaking air. Is there any real reason to buy a BOV rather than for PSCHHH!! sound? Or can the factory one cope with it well enough?

[joh21m]

i've got the factory BOV still on, i also have a POD and i can hear the pssscchhhh... save your money and only replace it if you need to.

The best BOV you can buy?

nothing - keep your stocker, or upgrade to 2nd Hand GTR ones ($150 max)

I have a GFB Mach 1 on my desk, that thing was f*cking loud, I hate attracting attention so it came off...

On the GTR I will be sticking with the stock BOV's they should flow enough for my GT2530's..

[R31Nismoid]

stock GTR BOV's flow enough for well over 500awkw in a GTR

[Yorik]

Yeah I am new to the GTR thing, but I modified my SR20 180SX to befairly hard. I have spoken to a friend who has owned a few GTR's, he said the same thing. I just wish I didn't live in the back blocks of nowhere so I could ask more of these questions...

At first I was thinking that the GTR BOV's would be like the stock S13 bypass valves. Then I realised I don't think I ahve seen too many GTR's with aftermarket BOV's..

generally speaking, unless your factory BOV is faulty, theres no real reason to change it, other than to get the sound you want. You can pick up cheap 2nd hand BOVs, if i were you id throw on a nice loud atmo BOV, as being new to the turbo scene, you'll love it then once your over the noise and attention, stick a nice sealing plumbback on it. You will still get a bit of sound if you run an exposed pod filter anyways.

sounds like your car is just a baby at the moment so i wouldnt be concerned about the stock bov handling big boost, because you wont be running big boost. You will more than likely be running around 1bar with basic exh/intake mods and a bleeder, that will be fine.

Are the Greddy Type R and Type S BOVs plumback or atmo?

[Baz]

Yeah my car is basically unmodded and unchanged at the moment. I may have a bit of fun just running low boost and an atmo BOV at this point in time until I get used to the power of a faster car. I was planning to focus more on the handling of the car instead of just raw power. Just going to have fun at first while I build up a couple of ideas for the future

Mate, if i was still in Perth, i'd pat you on the back.

You've got a great attitude and approach to performace. Starting and working slowly is the ebst way. Rather than go making a 400w machine and not know how to use it.
