Which BOV? [Merged 3-8] what bov best bov

[Batgirl]

I am looking at replacing my BOV. I was looking at the Greddy XS, but I seem to be seeing people with Greddy problems aplenty. What BOV do you like? Why?

Also, what is a safe PSI for a stock turbo? I hear rumors that anything beyond 14 will raise hell on the engine.

Thanks for your help!

Neither there both junk I have witness then both leak, if I were you either sell or trade for 1g bov. Or keep the greddy replace diagram with ngr

Sell both, buy a TiAL

Sell both, buy a TiAL

Good answer. Or a crushed 1g should hold 22psi.

 

[nfernotalon]

Yea my crushed stock bov held 27psi on my hx35.

I have greddy type s with ngr diaphragm and love it. Holds 20 psi without a problem. They also have an o-ring which ensures sealing. I like it!

 

[Tiki2777]

Or a real HKS SSQV...

Learned my lesson with Crushed 1g BOV - I believe the BOV started sticking open I believe after the "first" crush. This lead to turbo whine after a few pools down the street, and my jaw dropped. I thought I overspun turbo and was like WTF. Anyone crushing should just be safe and spend the money on an aftermarket one. Not worth finding pieces of turbo in your exhaust or intake...

That's just my opinion.

Also venting to air sounds cool, but makes her run like poop.

If you go with the greedy. Get the ngr.

I've been using a knock-off Type-S (the one included with Punishment FMIC) for about a year now. It's still working just fine with about 35psi from a 60mm H1E. No leaks during BLT's and no compressor surge when venting. My only complaint is that once I started venting 30psi+ the O-ring sometimes blows off. I plan to replace it with a better Viton O-ring and a dab of silicone sealant.

I'd go for the Type-s. I ran one for about 8 years and never had an issue. Even as much as 50 psi boost. Does the Blitz use a brass valve? If so, i wouldn't even consider it.

Agreed. Check the Diaphragm, if it is orange its a ngr. No need to replace. If its blue its a Greddy, Replace it

I have also never had a problem with my Greddy Type S. Been running it over 20 psi for 7 years.

 

[Abe'sGST]

My greddy type s works great, no problems.

 

[diambo4life]

Gus modded -1G BOV

 

[get_boosted]

for your goals the type s will do. if you plan on upgrading I would sell both and get a tial

 

[tomas123]

TIAL!!! or hks ssqv (legit one). Others sound like poop

 

[little_1]

I run blitz and it works fine for me but im only running 15 psi right now.

 

[96atawd]

Based solely on sound I prefer the type s. And as said before, replace the diaphragm with the NGR and it should hold fine.

SPECIAL! - Shop NGR

I just got my hands on a BIG 16g and plan to put 350hp to the ground. I know I need a 255 with amfr and ~750cc injectors ecu, but how do I build more boost from the 16g wg? I have a knock off tial external laying here, but I don't think using that is a good idea....plus I would have to buy a o2 with ewg

sorry wrong thread...

the crushed 1g bov will hold ~22psi correct?

 

[GRAVEDIGGER]

the crushed 1g bov will hold ~22psi correct?

Yeah, it will easily hold that. I have mine currently holding 27-28psi.
