Bov

[R34P3R]

ive installed a ssq bov a few weeks back and not sure if i should keep it or not... ive noticed since i have installed it, the car has been getting about 100ks less out of the tank and also its shooting out black smoke when i semi floor it...

but i really like the noise of it..

would it be better to keep it and get the car tuned for it or put the stock one back on?

I dont see how a bov will cause your fuel economy to worsen, something else is up perhaps?

[R34P3R]

talked to hyperdrive for a service and was told that because the air is being shot out of the bov the afm thinks it still in the engine so it puts more petrol into the engine to even out the levels.

have you blocked the pipe were the original plumb back wen bak into the intake or you could just sell the hks to me lol

[RICCA]

Well if you want to sell im 100% buy

tighten it up max, it might be opening to much to early.

If you've blocked the return pipe and the new bov is done up tight enough, it should only be fueling up on changes or liftoff. If it's pumping black smoke when you boot it, then there's a leak somewhere

[R34P3R]

its set to the loosest setting. when its tight i get a flutter and i was told its not good for the turbo

[Pattygtst]

The jury is 50-50 on fultter/compressor surge turbo damage. Personally i dont think it does much if any damage. Having said that tighten yours max and leave it for a full tank and see how you go. Even if flutter does damage it wont do shit on one tank of fuel.

I hear SSQ leak often so could be faulty bov too

its a copy hks, probaly the reason why..I checked it last time, looked like it was installed properly with the plumb blocked off

a copy hks? well there u go.. you get what u pay for.

Try and get the geniune parts when you can! saves alot of hassles.. as it usually will fit and work the first time!

A bit of black smoke when u floor it is normal for a turbo car tho.

[bubba]

I had to wind my arc bov up real tight to stop it leaking at idle.. as bizarre as it sounds, it was pushing air out! so now I have mad flutters except when I spool it up then lift off hard. This poor little turbo has taken a beating on the RB20 and now for nearly a year on the RB30.. she'll be right

[Kaido_RR]

yes you car is running richer due to you running an atmosphere venting bov. to stop this put stock bov back on or get somesort of ecu(powerfc/safc) and get it tune

when i bought it the guy said it had hks written on it so i bought it... arrived 1 week later and the adapter had hks written on it... was really pissed off.. smsed him and he wouldnt reply.. hung up calls aswell

[R33_NICK]

i have an hks ssqv as well installed on my car but my fuel economy didnt change much but it does cause my exhaust back fire which it doesnt with my stock bov sometimes when i change gears

from what i know, a bov might make a car run rich due to the fact that it releases the air that was recorded from the afm so the ecu thinks the the amount of air the afm reads is still goin into the manifold and kept it at that exact amount of fuel required for the amount of air recorded by the afm only to realise that the amount of air recorded from the afm has been released by the bov only happens to bov that vents to the atmosphere

on cars with afm the bov will still cause the same incident but on cars with map sensors, it doesnt affect it because it reads manifold pressure(i think) do you have an aftermarket ecu?

What a d*ck!

sh!t. Even without tune it shouldnt b that bad, tho mike is right, it will run richer... and tend to stall if u drop the revs very quickly. Tho my blitz bov is running and ive yet to install my safc 2. And i still get roughly 450 for tank.

Hrm, maybe count that as sunk cost and go for a real hks ssq? Try and find one that you can look at first (there is alot of them going around 2nd hand).. or get of reputable sellers... i know Kudos (andrew) on here is very trustworthy as ive bought things off him before.. always answers pm fast, though im not sure if he sells bov's..

[R34P3R]

lol no money to buy anything right now...

gonna half tighten it and see how it goes.. if its still bad ill put the stock on back on

[R34P3R]

this is too gay and cant be stuffed buying a safc and tune to make it run good..... putting stock on back on tonight.... gonna miss the sound but my pod still makes a sound [enough to get pulled over for =/.. ]

[R34P3R]

mega gay

As Bubba said, it wont run rich unless the BOV is actuating.

If the BOV is actuating under load. Its not tight enough.

Properly working Atmospheric BOV's will only 'smoke' and run 'rich' when they need to "Blow off" extra air. (And that's to do with changes in Load)

Just tighten it, make it work properly.

That 'Extra' fuel coming through the exhaust would have just gotten burnt by an unloaded engine anyway. Which will not effect your economy. Really, its not extra fuel, because it was going to get injected anyway.

(On a side note, AT A GUESS, because the princeples of induction may counter this - if you plumb back a bov in front of the AFM, you will read that portion of air twice, and then there will be 'extra' fuel injected.)

Your smoke on load is a sign the BOV may not be operating correctly.

I think im just repeating what people have said ?

However there are some myth's being said too.
