Hks Bov

[dinero]

Hi all,

I am trying to get info on the following BOV. It is apparently called a 'HKS twin sequential blow off valve', but i can't seem to find any info on the net (forum, google,youtube, etc). The only thing i found was a pic on google image.

Can anyone help?

Cheers,

D

maybe search for hks distributors and ask for them to email a catalogue

[Sinista32]

Search - HKS SSQV Twin ?

[Sinista32]

Disregard above post.

I have never seen a HKS one like that and also cant find anything on the internet.

Weird!

Could be Old Skool HKS.

I have a pair of HKS Bov's that are old skool and chromed up which are different again to the one in your Pic.

cool, thanks guys. Yeah i tried the HKS site but had no luck. I think it is an old school one though.

It is fitted to a 1997 model honda, but problem is the SSQV where out then so these might even pre-date 1995...possible that someone put a HKS end mouth onto a different kind of BOV. It might have also been a recirculation valve preveously which maybe why this person put a different end onto it.

i have the same blow off valve on my 32, its HKS old version of there super sequential blow off valve. what kind of info are you looking for?

[dinero]

thanks guys..

'Viper_r32' - i was just wondering on what sound is it actually suppose to make? because at the moment, i dont really notice any difference in the sound when you turn the screw on the top to either A or B? When i don't rev it flutters with a low whistle (you can barely hear) but when i kick it it just gives of a deep whoooosh sound??? (forgive me for my terminology and description)

I was also wondering on whether the amount of boost you run makes a difference? I heard that it does with SSQV? just want to verify it thats all.

cheers

I have one aswell, they make bugger all noise...I dare say because when they were made no-one cared about wank wank fully hektic bov noises

[srbskyline]

hey man ,i had the same blow off valva on my r33 gts, your missing the trumpet attachment.. with this its one of the loudest bov ever made!! ring a few tuning shops in canberra and ask for hks TTSSQV trumpet

[dinero]

lol 'HEKTIK BOV NOISES'... Yeah man, im not really a fan of it being loud too, but i do like the whistling sound, makes me feel like im playing need for speed while i'm driving... lol

srbskyline - thanks mate. did u have the trumpet yourself?

revving at low rpm, the blow off valve should be quiet, but it gets louder when it releases at higher revs because its pushing through a larger volume of air and you get the whoosh sound. the flutter sound is herd when the blow off valve is trying to release the air slowly in sections, that's why its called sequential. it dose this so that the pressure of boost to the turbo dos not drop down to rapidly encase you what to put the boot straight down again. the screw just adjusts the tension of the spring, and it makes little difference on how much its turned, the further out the spring is, the less tension it has and the further the screw is in the more tension. you want it to be in enough that spring has some tension to hold the valve, but not to much that it keeps the valve shut. this verys depending on how much boost you run. but generally having it set a little looser than half way will be fine.

thanks viper, that helps heaps, i think its just that the add on piece is missing hence no noise

[GTRKat]

I think that no noises sound better. I often get "wow Kat your car has no flutter" and I think that's a good thing but of course each to their own!

[Trozzle]

Yeah I agree Kat, mine currently has a rather loud BoV (at least as far as I'm concerned) and It does get a little annoying.

I'd prefer a sharp "PST" sound as opposed to the typical (and my current) "WHHHHOOOOOOSSSSHHHH MA'F*KA"

That being said, I do like the funny sound you can create when just touching the throttle then letting off enough to open the valve...kinda sounds like my car is snoring...like a dragon before you wake it...yes I'm not a wanker

[dinero]

yeah i agree with you both, but sometimes the snoring thing sound is good, lol troy. and im no wank3r either..

i just wanted to make sure that the bov is working as its suppose to and i didnt get screwed. lol..

[GTRKat]

Hahaha well I do tend to use the term "wank off valve" when I hear them with people driving past

lol 'HEKTIK BOV NOISES'... Yeah man, im not really a fan of it being loud too, but i do like the whistling sound, makes me feel like im playing need for speed while i'm driving... lol

srbskyline - thanks mate. did u have the trumpet yourself?

yea man, although its somewhat a collectors item now, much like a 32 vspec.. i still have the trumpet in original condition, only thing ive added to it is a strut brace

i can sell it to you for $200000, and then you can make noise like your car was intended to

[NZM.031]

yeh i have one of those bovs on my r32.. its the original sequential. mine has a green insert and it makes a two stage noise... but no flutter..

[dinero]

srbskyline - SOLD!!!!!! lol

NZM.031 - yeah man that is weird, but mine flutters, lol.

Anyways, I have returned my BOV to stock as i found the BOV to be doing nothing special for me (apart from the loud back fire sound), lol. so GTRKat, lol I have a BOV for sale if you want it, lol.

yeah, definitely prefer the stock BOV atm.
