I've fitted dual GTR bov's on my car. They work perfectly, as for sound, they sound excellent - very quiet. as far as sounding "exactly" like a GTR, I think you really need to mount them in the same position as a GTR (under the right hand front skirt) on the cooler entry and run the factory plastic solid return pipe etc.

there is some pics in this thread how I mounted them... http://www.skylinesaustralia.com/forums/Pr...90&start=90

cheers

Great stuff, exactly what i was looking for, cheers mate!

I'm not after loud, i just want the sound. I still don't really know what i'll be looking for to fit these as i haven't got the engine yet, but where is the stock bov located on an R34 GTT? Can that setup be made to fit in the factory location, or will i have to move it?

Hi Guys, sorry to hijack the thread but are you using GTR bovs on RB25DET's just for noise or is there another purpose?

Will the standard RB25DET one handle 300rwkw?

Usually just replacing a dead factory one.

GTR ones are just stronger. Stock BOV might be fine either way. Plenty making 300rwkw on them.

Ok but that still sounds quite similar to the twin setup. I'm not really after the flutter effect, just the sound of the bov. Does your bov sound like that all the time, or just under heavy load?

Say i wanted to install the twin setup on my car, what would need to be done? Is it possible? How would it differ to the single setup?

MOST people don't use them just for the noise, rather the fact that they are a very very good bov and can handle a lot of boost. I personally love the sound of them, i think they are the best sounding bov you can get. So i'm going for the upgrade, but really want the sound as well seeing as they sound so good.

Ok the issue is room. Once you see the GTR BOV assembly you'll understand, there is not a lot of room with the return piping etc.

You have to have cooler piping that goes in/around the guard on the drivers side - that's where a GTR has them - POST cooler.

That BOV setup was when i had a single - running duals now in a different config however the BOV was right next to the throttle body (basically like a factory RB25 for all intents and purposes).

It would only blow off like that on 24psi, when it was doing 17psi it was nowhere near as pronounced.

Doubles differ to single as on low throttle the dual ones "bounce" off each other. Its very hard to explain unless you've heard a GTR on light/trailing throttle and back off. It does sound very cool IMO. No other BOV setup sounds like it as they are all single.

So it's not as simple as remove stock bov, replace with GTR bov and replace stock plumbing with bigger plumbing to suit GTR bov? I will have a FMIC with piping going from drivers side back over the fan shroud. What do i need to do to install the bovs?

I do understand what you mean with the "bouncing", i've driven a couple of GTR's that sounded great with their stock bovs. Made me fall in love with the GTR bovs :(

And what, just have them hang there? :(

They are the size of two grown mans hands roughly in terms of area (as you can see from the pic)

I'm going to struggle to see where you can mount something like that neatly in a factory GT-T/GTS-T position

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
