install hks ssq bov.

[monkeyslide17]

Ok I need just alittle help here you guys. So today I just picked up the flange for the bov, now to install the bov. What needs to be ran and where? If by chance you would be able to show a diagram would be helpful. thanks

[HalveBlue]

Uh...

Vacuum line from BOV to Top Left vacuum port at throttle body. If you want to recirculate it, hose to route the discharged air back into the intake.

That's it.

[redtop91]

IIRC the SSQV comes with a vacuum diagram showing you how to route everything. You might start there...

[monkeyslide17]

i dont have that paper with the bov thats the only reason im asking.. thanks for the help all.

yup, a good vacuum source, and if your still running a mafs then yyour gonna need to recurculate it

GL

[monkeyslide17]

So if im still raning a mafs I will have to recurculate? why is that? :duh:

What would happen if I did not recurclate?

[YoungGun]

Search, it can make you run rich and idle poorly.

[240trainee]

and make cool noises

[singlecamslam]

i run a non recirculated HKS bov with my MAF. Runs perfectly fine, as long as it stays closed at idle.

[Thursday]

if unmetered air gets past the mafs it will cause rich conditions and your car will stumble badly when your under decel.

you can trick the ecu by running a safc

edit, you can run it as long as the valve stays closed upon idle. which means a stiffer spring

[txrxs]

the HKS ssqv stays closed at idle. No need to adjust anything. You may have a slight rich condition right after shifting but most likely won't be a big deal.

[KiLLeR2001]

I bought a recirculation piece for my HKS SSQV, cheapest way to have your car running like its suppose to until you can get a SAFC or something to compensate for the atmospheric bov.

The top left nipple on the TB is the only vacuum source to use. This port only recieves a signal (vacuum/boost) once the throttle is opened past idle. This keeps the recirc valve from staying open at idle/decel.

So if im still raning a mafs I will have to recurculate? why is that? :duh:

What would happen if I did not recurclate?

The PCM in a mass air controlled vehicle delivers fuel based on (among other variables) the mass quanity (gm/s) of air that passes through the MAFS. The computer has no means to determine that air has been purged from the system (blow off valve) and sends fuel for the air which it's logic determines is still present.

the HKS ssqv stays closed at idle. No need to adjust anything. You may have a slight rich condition right after shifting but most likely won't be a big deal.

I dont agree with the concept of a universal valve without spring pressure adjustment. The spring must be heavy enough light enough to allow proper valve modulation (response and lift) under varying conditions yet heavy enough seal the valve under heavy vacuum/boost.
A universal spring rate may be to heavy for some set-ups (experiencing compressor surge?) and to light for others ( intake of unfiltered air/ boost leak). This should not be a "one size fits all" components.

[sumoboi7]

my bov is teed with the top left nipple and the top right nipple. what is the top right one? this gave me trouble with my boost gauge. but im about to do a different bov so i wanna run the vacuum lines right.

[RedtopTech]

The top right nipple is a basic vacuum port. Dont T the blow off at all. have it secluded on only the top left nipple.

[SuicidnS13]

You shouldnt have problems running the HKS SSQV. A bunch of my friends and my self are all running this BOV as an open atmospheric BOV with factory maf locations and ecu's with no issues on sr20dets.

[fliprayzin240sx]

HKS SSQ is actually one of the few BOV that you could get away with, without having to recirc it on an SR. It doesnt open up and dump air quickly as most BOV. Its dual chamber design gives the ECU just enough time to recover from the rich condition. You just have to play with it a bit till either the ECU gets used to it or till you get the bov just tight enough where it wouldnt surge nor would it stall.

[hassanbakar123]

couldn't you relocate the maf and it seems to me it would be more accurate on the amount of air actually going in the intake, and the bov would be more effective

downside: heat, and some people say the the intake air temp will be off a little.....


idk just want some thoughts

I'v seen ppl relocate the maf to the cold side a lot. seems like its really popular these days.

def seems like it would be a lot more accurate since it would be accounting all air flow into the throttle body.


And thanks to this thread i may have just found out why my car is running so shitty sice i put it back together the other day.

Couldnt of been explained any better. Thats exactly how its suppose to look. Hahah

[jsasrsr]

well.. my ssqv doesnt even blow off for some reason.. argh.

[adrians_s13]

I can easily say, for the most part, you can run an ssqv and not have idle problems... its pretty good at closing up.

I run mine vented w/ no problems... yeah I backfire every now and then... but who doesn't enjoy a lil backfire every now and then? hehe

pull type ftw

[idahotuner]

^ very true. and the flames it shoots are cool too.

[legacy927]

^^^my car backfired out of no where right next to the cop...I was like..HOLY SHIT...

[Z33dori]

why would venting to the atmosphere cause it to back fire?

[Jtuned_andy]

why would venting to the atmosphere cause it to back fire?

un-metered air causes rich driving conditions = backfire

I dunno if answered this question, cuz i was intrested in doing this too. Any problems?

[mjjstang]

I can only speculate that the boosted air may cause an issue with the sensor monitoring the flow of air. I would think that as it is under more pressure, the sensor is not a pressure sensor but a flow sensor, so it may give false readings? But at any rate, I don't think that the MAF is designed to handle pressure, the components would probably stress and leak. Anybody want to school me please.

and why do people keep saying "un-metered" air. The situation is more "over-metered" air. Meter reads more air than is actually there.
