Atmospheric Bov's

[R3sp3ct]

Hi all,

Just a quick questions about bov's. Standard bov's are plumback therefore all hoses are attached, but when you install an atmospheric bov you have to block one hose. What would happen if you removed that hose and blocked it on a standard bov?

it will make the standard bov atmospheric.

i dont know about skylines, but out of boredom i have done this to other cars and it sounds like a weak fanny fart.

worth a try but. it's not going to cost you anything

Good idea not posting this in the main Forced Induction thread... you'd be slain

All Skylines, as far as I know.. use BOV's that don't seal 100% They leak constantly through a small hole, to smoothen out response when driving. (clearly as they're leaking back to a point in front of the turbo behind the AFM, this doesn't upset running.

You cannot make the stock BOV work atmo, unless you block that hole up.

But hell, don't listen to me, i had to, 4 yrs ago, try it... hahhaa.

I only made it home by left foot braking, and always applying throttle when doing so...

Lack a GF and need some toosh toosh, then grab a proper atmo bov and tune it to NOT STALL with your bender / PFC / full ECU...

Just say'n

The reason im asking crazy questions is my friend has an atmospheric GFB Mach1 bov and has no stalling issues what so ever, and everyone ive talked to about bov's says if its not plumback then your car will have inconsistant revs resulting in stalling. I wanted to know if the standard bov could act like an atmospheric and make different noises without causing them problems. That way you could have fun without spending extra on a new bov. I wont be doing this just a quiery .

Yah, the result isn't consistent. I too, have mates who've run atmo bov's on AFM'd cars just fine, which goes against the war cry

As long as you can adjust the preload so it doesn't open at idle, it wont stall.

To cure stalling when slowing, ppl raise the idle a little, so the idle solenoid doesn't have to work so hard to catch it.

To cure the pops and flame during hi rpm gear shift, ppl lean out the fuel cells in that area, so leaning all the 0% throttle (vertical / load) cells in the higher rpm changes (horizontal)

Some get it to work, some don't

Even the Datto chased revs without it hooked up. I got myself a GFB stealth FX and can now have it whatever ratio I want atmo or plumb back as long as I have enough air going back to the intake. Works a treat though I usually have it all plumb back cos it draws enough attention as is.
