Where Is The Best Place To Put A Bov On The Intercooler Piping ?

[Tweaky]

Ye soz - where it is, as stated, is fine mate.

Im running 270/280rwkw, not a problem - 8,000km's as it is.

What recirc BOV are you using?

GTR BOV's cost for gain, are unbeatable value.

Even a single GTR BOV is good for 300rwkw or so. Much more 2 is advisable as you get a tiny bit of surge (i was when running 24psi/370rwkw on single GTR BOV)

It is currently running a turbosmart supersonic bov & was looking of replacing it with the same brand but in a plumb back system. Are GTR bov alot better in quaility then turbosmart ?

They are factory, and are designed to work as made - for many years.

Quality is impeccable.

Don't expect nice shiny colours though

I can't comment on the quality comparison, but I've not heard of one issue with people using GT-R BOV's. When I was looking for one a couple of days ago, I got a heap of people offering to sell me one so you'll have no issues finding it...people run BIG BOOST with these BOVs on their GTRs and never have trouble.

Quick bump to ask something...

So I received the GT-R BOV off a fellow forum member yesterday...fitted it to the car, but didn't get a chance to drive it until work this morning...

First gear change with ANY throttle gave me HEAPS of flutter...gave it a tiny bit more and changed again, more flutter...I was also noticing it would idle anywhere between 1500 - 2000rpm...

Didn't take it into +manifold pressure at all the whole way, and when I pulled up at work I'd done exactly as I thought - left the manifold pressure line to the BOV disconnected. My question is, would this have been running even remotely lean since this was just sucking air when idling? I figured even if it were, it wouldn't have done anything bad since I drove like I didn't even have a right foot all the way to work (only about 5 minute drive so car barely gets warm)

[Beer Baron]

i wouldn't worry about it.

[Trozzle]

Yeah I'm not too fussed, just thought I'd ask anyway - just in case.

[Trozzle]

bump again..

After taking the car for a spin back home on my lunch break, I got to hear the actual sound created by the BOV...is it supposed to sound the same as a short sharp whistle that you'd create with your mouth, then just like a quiet hiss until you get back onto boost?

I also noticed that it does not fully close off the hole when there is no pressure applied from either side...does this mean it will be constantly leaking? particularly since I don't run a return pipe?
