Ok guys, need your help here. The EVO X seems to respond well to the HKS SSQ BOV and so far, no issues (from what I've seen).

Now, MY only issue is, will it be good for the car in the long run? I've heard running a BOV atmospherically was bad, but it seems to be working on this car. So what's recommended, atmospherically or recirculated?

And, is it really being RICEY when you have a BOV? I mean, the car comes with a turbo and it's born and bred to be a race car, so it's not like someone with a Civic, throw on a turbo for HP and go "swooshing" around the neighborhood. And Keiichi Tsuchiya drove a S14 (or was it S15?) with a turbo kit and it had a BOV, so is it really ricey?

Please help me out!!! Thanks!!!!

 

How do you know it's not hurting power? Have you dynoed before and after the install? BOV on the Evo's just make them run richer...the X already runs way overly rich from the factory so adding a BOV should just be compounding this and negatively affecting your AFR.

 

if you're worried about other peoples opinions of what you do to your car then leave it stock and seak counseling.


that aside, i've never seen a bov (atmo or recirc) be "bad" for a car. it can effect spoolup depending on size of the turbo and a few other factors...but if you don't mind waiting an extra 50-100 rpms for full spool on a large turbo then go for. there's nothing more fun then scarring the crap out of pedestrians with a loud as **** hks with a gold insert at 20+ PSI! lmao

 

Exactly, run what you want!! I have had my hks ssqv on for 2 months now without any problems. the X's map sensor is better than previous models and seems to correct the rich/stumbling/stalling issues that the other evos/ dsms seem to have.

I also ran the stock evo x bov open without problems. I am building some intake pipes to sell and I am not including recirc ports. So if you want an intake I have them.

And for a cheap plug, I have an HKS SSQV with recirc fittings and all that will most likley fit onto your Evo X for sale. (It's just not advertized, as I have been lazy to create an ad in the FS section. PM me if you want pictures of it. It's in perfect shape, and I am sure I still have the original box too.

 

With just an intake cone filter my car has a pretty decently loud BOV stock.

I guess the local rice boyz would be more impressed if it was even louder though...

 

OK dont listen to this.

VTA BOV are very very bad for a car that uses a MAF sensor (like the EVO's). But more so what makes having a BOV "stupid" is the fact that you DONT need it. The stock part is a good piece and doesnt need to be changed.

Also, BOVs DO NOT effect spool up.

If you dont know what the hell you are talking about (not just you robbie, but everyone that types false knowledge), then keep you fingers away from the keyboard.

 

Oh yeah, and its super ricey.

 

Nothing like paying good money for a part that makes your Evo run and sound worse. Spend your money on a nice exhuast if you want to make the car louder and actually improve the way it runs.

 

i dont have a X but ive done alot of research about this bov on this car, and if you put a bc at stock psi, and intake, and that bov, you will be fine, with no tune, because the car runs rich at higher rpm's, the BC with fix that, then the intake adds more air so the BOV doesnt effect it that much.

 

WRONG. PLEASE STOP SPEADING MIS INFO

a VTA BOV will effect a MAF sensor car (ie EVO) in a BAD way. It dont matter if the car has an intake and stock psi.

a VTA (vent to atmosphere) BOV on a MAF sensor car is NOT GOOD.

 

So recirculating BOV is best for the Evo X?

 

Yes.

Thank god someone understands.

 

so can the HKS BOV recirculate or is it only a VTA?

And not to bash on anyone, but I want to hear people's opinion on HOW it's ricey. I just can't seem to figure that one out on my own. I always thought it was ricey if your car wasn't factory turbo'd or if u had an economy car and u added a turbo with a BOV...

 

the HKS can recirc. There's adapters out there.
