Just ogt my HKS SQV, and not sure whether to run it VTA or Recirc.
I have heard major problems running the idle smooth with the vta

Any ideas on this. I also purchased the Recirc HKS Flange in order to get everything installed smoothly.

Any ideas would help greatly,

Thanks,

 

I'd recirculate it. I've been running the SSQV VTA on my Evo for quite a while now, and while the sound's pretty cool, the bogging in stop-and-go traffic most definitely gets old after a while. Though either way, installation is nothing at all, so you can just try them both since you have that option and see if you can live with the VTA problems (assuming you care about the sound). Then when you get sick of it, just add the recirc. fitting which would take about 10 minutes.

 

sorry for the ignorance but what does VTA stand for.?

 

Vent to Atmosphere

 

Thanks Leandrin11,

Thats about what i was hearing too. Did you install your ssqv yourself? If so, any tips working around that snap ring?, as I hear it is difficult.

Thanks again,

 

It didnt even click . sorry. but thanks for the responce

 

snap ring I had plenty of trouble with. Be sure you get a good pair of snap ring pliers, ones without the spring. I used the craftsman plyers without the spring in the middle of the plyers. Worked on the first chance.

I have mine VTA'ing and I only get some stalling once in a while from high rpm drops. I also think it's because I have somehting loose cause it worked fine for about 3 hours, then started acting up. I have to take everything out to install my boost controller so i'll update you then.

questions? pm me

 

dude you have to recirc it. even with the recirc i still have some bogging. without it i actually had it stall a few times. i put the fitting to recirc, have it going right back in. if im cruising at about 3K rpms like on the highway i still cant clutch in without the RPMS dropping way below 1 and almost stalling. i have to let off the gas, let it blow off, then clutch in. this is even with the recirc kit. i have heard of a few other people having this same issue while recircing. just something to deal with i guess. the BOV works great though besides that. hold boost in well at high rpms.

 

well meng, I've seen quite a few people even on this board with their ssq venting and don't have problems. It's ironic though cause it ran fine for about 2-3 hours then after that, I noticed the dropping. I looked inside and I didn't tighten the screw much and the actual bov was starting to swivel on the pipe. But seriously it ran PERFECT for that 2-3 hour span so I'm thinking it's something lose. whatever though, i'll recirc if worst comes to worst

 

Just installed a HKS SSQV with the VTA setup on my friend's evo. His car didn't have any idle issues whatsoever. Maybe it's because of the colder temperature now? Or maybe it's just that he's only of the lucky ones. I hear from some vendors that 70% of Evos will have idle issues while the other 30% won't.

 

I heard something similiar about that 909. Mine ran fine for a while so i have no doubt I can make it run fine again

 

The problem with venting to atmosphere is that the MAF is before the bov. So whenever it opens, the bov is letting a huge amount of metered air out that the ecu is already accounting for fuel-wise, which results in rich conditions and black smoke during shifts. Add in the fact that most of the bov's out there (and the stock cbv) probably leak at least a little at idle, and now you are letting unmetered, unfiltered air in, and now your car won't idle right either. So if you want to be able to actually tune your car, recirc it. Or, if you just care about ricey bov noises and not about making your car run good, then go ahead and vent it to atmosphere.

A stock 90-94 Eclipse turbo cbv will hold over 30 psi without leaking if you modify it correctly (NOT by crushing it).

 

is the HKS BOV when you install it ,the bov don't make the engine drop the rpm because when i use the BLITZ BOV it will drop the rpm when i want try to stop my car

 

i've been running mine VTA for about 4 months w/ a grounding kit, and i get no bogging problems

 

do i also get a difference in the sound if i fit a recirc kit?

i have just fitted an SSQV with a recirc kit and cant here a single psshht
