adjusting hks ssq bov-help

[Kaido_RR]

hey,

I have a hks SSQ Bov, i know you can adjust it but i was wonding what happens if i adjust it is the sound any different? (cuz i am sick of the sound its makes thinking about replacing it with my stock bov), I heard some people have a problem with tehre car stalling at low rpm cuz of bov, will this happen if i change my hks one...? (at the moment its fine)

thanks mike

Hey, Mike. I have an HKS SSQV on my R33 as well. Adjusting the valve simply changes the point at which it activates, it doesn't change the sound.

I recently fitted a purple insert, which I got from Xspeed (have a look on their website). This reduces the frequency of the sound, so it is less piercing - net effect is it is less noticable. Dead easy to fit and dead easy to lose one of the grub screws!! (There are eight, but you only undo four to get the cover off!) You can also get a gold insert, but that doesn't change the sound - it just adds rice-value.

Meanwhile, if you are concerned about the effect of venting to atmo, then you can get a plumb-back insert instead, which converts your ssqv to plumb-back mode.

As for the low rpm stalling, the concensus seems to be that this is due to the Oxygen sensor being stuffed. The effect of your BOV venting to atmo might not help, but it is not the primary cause. I have never had any problem.

Hope this helps.

Cheers.

13_devil,

If your interested i wouldn't mind either swapping my GFB BOV (makes the usual PSSSTTT sound) for your HKS or buying it off you if you want to sell it.

Just pull the insert out all together. It then doesnt make any noise at all. Simple.

yeh I SSQV, don't have anything in the centre so makes no sound at all... perfect.

Surely it still makes some sort of noise? All the insert does is act like a whistle and change the tone, I would have thought. So how quiet is it?

Cheers.

seriously guiet enough not to hear it in the cabin (over exhaust)..... It does make a really really quick whipping sound (lasting about about 1/10 of a second), but its that unnoticable that I would call it silent.

Don't forget you can get 2 inserts:

The Mercedes shaped ones (high pitchied noist)

Circular insert (psshhhhhhht)

nothing (as above)

when i had one on i had no insert cause the high pitch thing pissed me off.

maybe i had it too loose or too tight cause it did make a fipp fipp fipp noise for about 1 second, which sounded pretty cool but it got mixed up with the sound that the pod makes at backing off throttle so it sounded gay unless i only just let off very slightly so the pod wouldnt go off.

[Jimbo2000]

ps it also took a lot of low down response away, just felt a bit sluggish at low revs so i took it off

if you want to sell the ssqv, i am interested in buying it off ya

pm me if you ever wana sell it!
