How Much Psi Can Stock R32/r33 Bov Handle

[Cubes]

i found the opposite while using the stock ECU, NO BOV caused no end of issues (RB25) with stalling and throttle response.

GTR BOV went on, problem went away

But stalling etc is largely due to driving style as your already aware im sure

Not sure if its the complete opposite.

Throttle response was up with no bov (i.e partially on the throttle through a corner then nailing it) however it did have stalling issues and often backfiring on down changes or coming to a stop. The bastard always would stall driving in to my driveway.

Nothing I did to the pfc prevented it stalling or having the jerkyness drivability issue at low rpm when making some boost.

No bov... It did feel nice when I selected the next gear on 'full boost' partial throttle with a slow gear change as I didn't have to wait for the turbo to spool, boost was just there instantly. But.... I don't drive like that 90% of the time. Probably why I get 10.5-11l/100km's.

lol at chirping... I can chirp fourth if I try.. lol not that its too good for the box. Chirping has everything to do with the clutch and how one shifts or should I say slaps.

I know this is a very old thread but does anyone know where you can get a plumback hose for the GT-R stock BOV? It's like 40mm from the BOV to 30mm on the black hose that goes back to the intake. I can't read the vernier caliper that well so the size maybe way off but you get the idea.

Thanks.

Hrm... i think i have some in the boot of my car.

Lot of effort/cost to send to where you are - surely you can just get some hose made up mate?

And by that i just mean any old hose cut to suit, you dont need it to be any specific type really

[teng]

I see. Doesn't have to be any special reducer hose. I was searching for HKS straight reducers but can't find any online. I'll go to the workshop today and see if i can get a normal hose to fit.

Thanks R31Nismoid.

i have stock gtst bov.... hole blocked, holds up to 25psi fine

[geraus]

Hey sorry to bring this old fourm back, but would blocking that bleed hole really make a diffrence joeyjojo? would i need another re-tune to do this? and how did u do it? did u just put a lil bit of weld? i wana give it a try to hold 17psi .

[joeyjoejoejuniorshabadoo]

i just used a tiny square of duct tape lol.... its squashed into place perfectly

[geraus]

oright il give it a try and see how it goes! thanks joey

oh sick!!! true! hey man did toa call u up? he said his gona give us the op6 rears! do u know if they are good?

[R31Nismoid]

Its only going make a difference if the stock one isnt working so well.

So don't expect something to happen

I've seen a GTS25t Bov handle 1.5Bar without issues for quite a while.
