Different types of BOV... Explain?

[Lisij77]

Hey all...

Thinking about buying a BOV, checked things around...
Found 2 types...
SSQV and not SSQV (i am thinking just one membrane with the spring).
Now, there is not a tiny bit of Ricer in me, so loud whooosh when shifting doesn't make my day... wouldn't care less...

My question... which one would be better... I am have T3/4 turbo sitting on the table waiting to be put in...

Just don't vent to atmosphere and you won't be a ricer! And don't get anything Blitz! Yeah, the HKS SSQV is a very good BOV. Another would be the Greddy Type S if you can find it.. Right now I have the Apexi Twin Chamber, I think that is a pretty good BOV.

Cant go wrong with the 1g BOV, sounds good, looks good when polished, holds boost well, can be crushed to hold more boost, and very very cheap!

The 1G BOV is all the street DSM world needs. Others exist by the same method theaters sell tickets: there's an ass for every seat.

My vote goes for GReddy BOV's, they hold high boost very well.

I don't know what venting to atmosphere has to do with being a "ricer".

Venting to atmosphere removes a restriction (2G MAF) before the turbo. With a HKS SSQV you won't be able to recirculate unless you buy a recirculation kit. Greddy does not make Type Ss anymore, but you can pick a cheap one up from www.dejonpowerhouse.com or from ebay. If you want Greddy, you can also get the new Greddy RS.

Also, you can't vent to atmosphere PROPERLY without a GM MAF and a MAFT unit.

i read about crushed 1g bov, but i also read about crashing it too much...

now, all that raised another question, that is related to BOV.
Recirculate or not?

If you searched at all you would find that is the most common question on here . Short answer (because I & most others have answered this question way to many times already) if your running the stock MAS you need to recirculate. If your running a GM MAF setup then you can vent. If you checked out the FAQ's you would find there is even a sticky on this subject:

To the origional poster what exactly do you want to know about bov operation? Here's the SSQV operation:

With a stock 1G or 2G MAF - No.
With a GM MAF and MAFT - Yes, you can, if you want to.

With a GM MAF and MAFT - Yes.

It doesn't mean you have to, it just means you could if you choose to without having to deal with a/f issues. There are still benefits to recirculate even with a MAFT setup, mainly the shot of air to help keeping the turbo spooled in between shifts.

That's true.

the Forge 1G is also a very good product. the adjustment screws on the Greddy Type-S and Type-RS are known to be somewhat temperamental.

DSMUnknown, are you talking about one of them? will it work in 1G DSM?

I have the GReddy Type-S recirculating currently. It holds boost like a champ and I have yet to have any problems with the adjustment screw. I would highly recommend the GReddy Type-S or Type RS.

eBay is known to have knock off Type-S BOVs though, so watch out with that.

As DGajre777 said, hit up www.dejonpowerhouse.com and take a look there.

Good luck choosing one!
