When I start to boost around sometimes around like 4 or 5 Grand my bov flutters like its just not lettin the boost go any higher, when i run around 20 psi. it just flutters and wont let me get higher, so i have to let off throttle and do it again. anyone knows why this is happining I have a HKS SSQV.
Please help meout on thisone.

 

First question: Is the SSQV recirculated or vented to atmosphere.

Second: Why did you get that BOV? (The best are the JDM MR & Forge)

Third: Are you at WOT when the BOV flutters open?

Fourth: How do you know you are hitting 20 PSI, and Did you turn the boost up?

What you may be experiencing is boost taper where the boost spikes to 20, then falls off a couple pounds toward redline.

 

Your HKS is the problem. Search. There's countless thread that discuss this specific problem and how to aid it.

 

Yes I am at WOT
I got the ssqv because I like how it sounds, I had no idea that there would be a problem with it like this.
I had the boost turned up with my MBC and my gauge was only reading about 17psi when this was happining, it never even got to 20.

 

Get a different BOV, forge, jdm evo. if it flutters thats not healthy for the turbo... try to adjust it, 10mm and unscrew the bolt more.

 

Sorry to tell you this but get rid of the SSQV BOV. Go back to stock which is much better, or buy a FORGE.

I won't even start on this "I want the sound". I'll leave that for someone else, migh want to get your flame suit though.

 

Worst Bov you could get. Make sure its not in backwards

 

your telling me you got this thing because of the sound?? your def messing with your turbo and your timing, causing you to run more rich. I installed an turbosmart dual port when I put in my intake and it fluttered and I took it off after 5 mins to put my stock IX DV back on. The sound is not worth the damage your eventually goin to cause to your engine. If you want the sound upgrade to a 50 trim and when you need 30+ psi then get an upgraded DV.

 

Flame on!

 

So that might explain why im runnin rich as hell. i mean I shoot black smoke everywhere when I get on the Throttle. well time for a new one... So forge is the way to go? and it sits on the upper IC pipe right? cuz thats were my SSQV is... well wow im amazed... but why would i need a flame suiet? will that **** blow my car up?

 

I have the SSQV, it sits as a replacement for the stock. It's not on the top of my intercooler piping. Mine is also NOT recirculating [it's just shooting into the atmosphere], and i have absolutely no problems.

Looks and sounds awesome

 

flame suit = melted evo........exactly lol

 

Awww I dont what that.. But when it was installed first it sat on theturbo intake pipe. and wasnt loud at all. then it was moved to the upper ic pipe. and it sounds great, but while it sat on the turbo pipe it shot out some what looked like oil thing, so thats why it was moved, so can some one tell me where itHAS to sit

 

You guys can keep your SSQV if you want to, it's not my car. But when you sell your car or trade it in, let me know so that I can steer clear of it!

Also, the Flame suit thing is just a joke. When people bust your ***** on here it's called flaming.

Any BOV that is VTA on an un-tuned car will cause problems, period. You may not notice that you have a problem because your car's ECU is compensation, however you are losing power also.

Look at it this way: Air enters your air box, past the filter to the MAF, The ECU sees how much air is going past the MAF, which tells the ECU how much fuel the car is going to need to dump into the car. Then the air passes the turbo and becomes pressurized, through the intercooler, and into the engine.

Now remember the ECU knows how much air is in the pipes, so when the BOV lets a bunch of it out and into the atmosphere you are now running pig rich. Not going to hurt the car, however you lose power.

If the car was intended to VTA don't you think the wonderful designers of the EVO would have made it that way from the factory?

Well, I guess they don't know what they are doing, I mean after all they probably have only built a few cars anyway, why listen to them?

But I supposed that someone who has driven the EVO for a few days will be the best person to determine how the BOV should be!

 

It HAS to sit in the garbage where it belongs. Any bov that vents to atmosphere is going to cause problems .

Long story short, if you want your car to run correctly put the stock back in.
