HKS SSQV Noise

[Zakanitis]

Well I installed my HKS SSQV today and well at first the vacuum line that looks like it goes to the intake mani, well, was to big to fit onto the small end of the BOV. But I decided just to zip tie it on there and its great.

Ok well my first noise w/o the zip tie was like a swirling noise. People who have this BOV know this noise quite well im guessin, because it will do this under low boost.

With the line zip tied it sounds well... I just cannot believe how loud this is. Its a very high pitch noise that will even scare you when hearing it near you if your not ready for it. It sounds like a bottle rocket going off in your face.

So is this what noise everyone else got from putting it on?


Oh, I even scared some old dude who hit is head getting into his truck in my town by going by

 

[Tsi_User]

Are you recirculating?

According to you profile you aren't and that's a no-no

 

[wvturbo2]

he's probably not and i know im not and i def. dont have the gm maf setup, but my car runs fine. a lil rich, but fine. I love the noise of the ssqv, yes it's def. loud and its a distinct noise. you can point it out on any car its on.

 

[DSM LoVeR 96]

yea i have the same noise too. i love it so much i remeber when i was younger i wanted my car to sound like this and now i have one ahaha its so sweet. im venting too. its like the onley blow off vavle u can run vetnted with out runing rich everywere because under boost the vavle is forced closed. Best Blow Off Vavle money acn by and i got mine for a steal. only 45$ with the flang for an evo and a recirce kit and yes it is a real HKS ahaha

Actually that's incorrect. It will still run rich. I too vented mine back in 2001 when I didn't know better and I can personally attest to the huge driveability improvement from re-circing it before getting the maft to vent properly.

It sealing has nothing to do with running rich. It's the fact that the ECU compensates for the amount of air the BOV is SUPPOSED to be releasing back into the intake during shifts, and when you are venting, it isn't getting that air so it just shoots a bunch of fuel in there and kills your spool for the next gear. Try using spell check next time. Got a headache from trying to read that.

 

[bpestilence]

It probably depends on how you have the BOV adjusted. My car does not go rich when shifting with the open-air SSQV, but I still ordered the recirc kit because I want the car to be more stealthy. (I have a wideband and have watched it under several different conditions)

 

[brute]

Got a headache from trying to read that.

I'm running it with a MAFT and absolutely no problems so far. No adjustment needed. Holds all the boost I throw at it (which isn't saying much) and never causes surge. Plus it makes my car sound like a Supra That's all that counts, right? Haha.

[talonalex92]

Aw! C'mon, TT supras with dual ssqv's are sweeeeeeeet.

 

[snowborder714]

Aw! C'mon, TT supras with dual ssqv's are sweeeeeeeet.

Supra's with dual Tials is better!

The many sounds of 2 DSM's W/HKS SSQV.

True DSMers recirculate fellas. Running a BOV open to the atmosphere is just like cutting the stock springs to lower the car or running stock black steelies in the front and nice aftermarket wheels in the back of a FWD car. It represents all that is wrong with the "import scene" - where function usually takes a backseat to image and flare. It's the main reason why muscle car guys make fun of the import scene, and why I can't disagree with them.

Please, just recirculate, make the rest of us DSMers proud. Show us that you didn't just buy a DSM for the cool BOV sound. Show us that you actually care about building/modding your DSM the right way.

 

[TunaTalon]

What's wrong with this thread? The founder had to answer a question about venting the BOV. I guess most of the readers (like me) just blew the question off as boring and missing caps. Maybe it's just coincidence but the posters in this thread who vent their BOV fail to capitalize the first words of their sentences. Nah.

That's the end of my vent, but my BOV/CBV is recirculated and that's just the way I like it.

 

[Moparbishi]

I took my hks to the local welding shop and he welded on a round piece of aluminum to the end of the bov and smoothed out the weld. Cost 16 bucks. You cant beat that with a stick.OM

Bah. Bandwagon BS. To each his own I say. If everyone does everything the same way, we might as well not even tune cars. Just keep them stock so that everyone is uniform.

Domestic guys make fun of import cars because they have to. It's human nature. I made fun of import cars when I was a domestic guy. Why? Because I was SURE that my 7-liter V-8 could smoke anything on the road. That was until I got destroyed by a Supra.

Sure, some people like open-air BOV's because of the sound they make. But that is no different than domestic guys and Rootes blowers. Definately not the most technologically advanced form of forced induction out there, but there is the sound of gear whine and the look of a polished blower sticking out of the hood that keep their sales up.

You could have also bought the HKS recirc kit which costs about $15 on eBay, and still kept the resale value. But as long as it works.

Are you referring to improper venting, or blow-through setups as well?

Bandwagon BS? Are you kidding me? The whole venting to the atmosphere is what caused the bandwagon jumpers, not those of us who believe in doing things correctly. It's not about doing things the same way. Hell I love innovation, but that's not what this is about. It's about doing certain things right, not doing things to sound cool when you shift. I'm a firm believer in form following function. That's what bothers me about the import scene. Most people seem to be more concerned with a loud BOV sound even when they know it's not the optimal setup.

If you vent to the atmosphere on a stock 1G or 2G MAF you're more concerned about looking cool on the streets than tuning your car to run at the best of its abilities. I guess I'm just too old for this scene and am not part of the "cool crowd". This will always be a hopeless debate. Carry on... I'm just poking my nose in here trying to point the newbs in the right direction.

(I just so happen to have a SSQV sitting in the garage, waiting on the recirc kit. Switching from a blow-through setup to a 2G MAS)

Improper venting. Blow-through setups are one of the proper ways to vent to the atmosphere.

I vent, and I don't see anything wrong with my sentences... I don't have a 4g63 tho... And I have a Tial.

 

[dsmulla]

Ludachris is right. Most people just love the sound but don't really care about function. This is just an endless debate, people who vent improperly just don't seem to understand the logic. A BOV has function to it in the force indcution system, its not just for sound people!!! Import scene won't improve much with the, "all show and no go," type of behaviour. However, it does put the people who actually do follow function over sound, at an advantage. Most people only think of short term gains then long term loses.

Just keep one think in mind, when someone who has BOV recirculated like its suppose to, and smokes you down the track, your sound won't matter at that point. Losing while you know you are doing something wrong, sucks a lot!!!

This is so true i have had so many people ask me why isn't my bov loud and i have to explain about recurculating..
Who cares about the cool noise isn't the power good enough ??
I also will be purchasing an SSQV bov in the next week..

 

[numlock666]

No matter how "normal" your car still runs, it isn't when it vents. It's been beaten to death on the forums already, the only reason it works better on a SSQV or Type-S, is because it actually stays closed until you let off the throttle. Unlike the stock CBV that will open at partial throttle, becomming a really big boost leak, causing bucking and poor drivability.

As a side note, I myself vent, but I do it with a blow-through.

 

[dsmulla]

I vent as well but with a GM-MAFT setup. This topic has been beaten to death as stated above but I guess people still don't get it.
