Cant find much info on how much boost the different bov's will hold. Needs to be recirculating ones also. Any info is appreciated

I started a thread almost a year ago asking what types of BOV's people boosting 25+ PSI use. The general census was Tial BOV and HKS SSQV BOV. The HKS SSQV can be recirculated you just need to buy an extra piece. The piece is like $12 from extremepsi. I have never used the Tial BOV, but from what I read you can't recirculate. Some people also mentioned the Forge BOV, but I have never used or seen it, so I can't say whether it recirculates.

So I would say Tial and HKS SSQV are top of the line when it comes to high PSI.

Stock 1G with the Dejon/Dodge mod works fine at 30+

Does it really?? I've read the Dodge Mod holds that much,but never heard first hand.

Forge does have a recirculating one. They call it a diverter valve. Im 99% sure that tial does not recirc. I will have to look into the hks one. thanks for the replies guys.

The Forge 1G recirculation valve is a solid product:

Regarding this product, you will need to send your Forge RV back to Forge Motorsport for the revised lock ring, to avoid the problems seen in the first link above. Here is the info:

EDIT: Here are a couple links where you can purchase such a product. FYI notice that this particular product only comes with a 1G flange, so it will not bolt up to a Greddy flange:

I have a flange with holes drilled for both. 1g and type-s

Awesome info in dsmunknown. Man i really appreciate it. Good to see that people are happy with them. Thats actually the one i was set on getting but wanted to see if there were any better options out there. Thanks for the help guys. I will let everyone know how it works out.

Yes. Kevin Kiggly runs one on his 9 second fwd dsm.

FYI, just called extremepsi and they said that the extra springs are STANDARD with forge.

HKS ssqv like mentioned above, you can get the seperate recirculation fitting for it from extremepsi, and probably many other vendors. They sound hella cool recirculated also, haha.

Always happy to help. You may need to use some Permatex silicone RTV sealant on the BOV flange to prevent any air leaks. Keep that in mind.

That's right. The green, yellow, and blue springs do come with the Forge 1G RV when you buy it from Extreme PSI. However, notice that if you decided to buy the same product from Slowboy Racing, they do not give these extra springs away. Click here to see. This just goes to show you another difference between Extreme PSI and SBR.

FYI if you have a one-of-a-kind, high horsepower 4G63, and you desire the red spring, I am told that you would currently have to purchase the Lancer Evolution VIII+ kit from Extreme PSI to recieve that particular spring. I have already emailed Hung about this several months ago.

If you absolutely need the red spring, he may be able to offer you a special deal for the spring or for a spring kit (which would include all of the springs). Email Hung for more information:

SBR currently offers a spring kit that includes all four springs at a decent price. With Extreme PSI, however, you're already getting 3-out-of-4 springs with one single purchase. In addition, with SBR's kit, you recieve three shims (aka "plates"), while with Extreme PSI you recieve two. For those of you who are wondering how many shims you need, two is more than enough for most applications.

By the way, I do not know how many shims come with a SBR purchase, but I assume that only the green spring is offered with the purchase of this Forge product. I have, however, bought my Forge 1G RV from Extreme PSI, so I am well aware of what is offered when buying from this vendor.

hmmmm. as of right now i wouldnt need the redspring. but i may very soon. i dont know that i will run the 57trim over 30psi. I like extremepsi because of the fast shipment. Slowboy takes forever on just about anything.

Slowboy get me stuff the next day. Maybe cause I'm so close, but then again, so are you, sbcxtreme.

Greddy type-r will get the job done

If you don't need to recirculate I would say Tial is the way to go. If you need to recirculate I have ran the Forge (that my pretty pic above ) & the Greddy type RS up to 22psi & both held without issues. I ran the Forge first & was defently happy with the quality but I could get it to blow off properly no matter which spring combo I ran & I would get major surge under light throttle. Just didn't like something on my setup but the quality of the valve was amazing & they gave me a full refund after a years use since I couldn't get it to work properly, defently a good company to deal with. Even with the lightest spring it help 20 psi without any leaks. I then switched to the Greddy Type RS, it to held fine at 22 psi & worked properly once I played around with the adjustment screw but I will be changing this in the spring to an HKS SSQV. The Greddy was working fine for me, I just don't like Greddy as a company & I have had nothing but bad luck with most of their products I have run & their warranty repairs are rediciously long so Im swapping out their products.

Edit: I also thought the Forge defently had the best sound (loudest & more of a pssst instead of a woosh) vs the stocker & the Greddy, for the ricer in you

Every Forge I've heard were little bird chirps that could barely be heard? I agree if you can vent properly, then the Tial is the way to go, but if you must recirculate, then the Greddy Type-R or the Forge are by far one of the bests

I'd stick with HKS w/recirc. Then when your ready to get rid of the recirculation take the insert out.

I have a SSQV with the adapter to reroute back into the system, I run about 21-23psi on pump and 33-35psi on race gas 110 leaded, Once my waste gate line came off and pegged my boost gauge it killed one of my couplers luckily and had no other damage but the hks held the boost ,(my autometer is the 30vac-45psi so I was at 45+psi)

They probably werent running the correct spring, when I ran the Forge is was a good amount louder then the other valves I've listed/run & IMO made a better type of noise. I believe the SSQV is fairly loud even when recirculated but I won't know how the 2 compare till the spring.

Remember he also has an A/T so would not be using the BOV on shifts

A BOV's purpose is to quickly release when the throttle plate closes to fully vent the shock wave of air that reverberates off the throttle plate back to the compressor which can cause potential damage. As such it must be matched both in flow and response to an individual application.

A 1G crushed BOV might stand up to 30psi (my 16yo D-G modded one leaks slightly at 15psi) but would not suggest it for a big HP application (note: the Greddy RS with a larger valve is rated to < 500HP).

Then again as cheap as they are used you could always run two

, yep. 2 would get the job done. Being auto, my BOV rarely gets used. It only goes off if I intentionally make it, or at the end of a run. I am not running high boost by any means, but my HKS SSQV is silent recirc'd even compared to my 1g. I though I was hallucinating at first, so I slapped the 1g back on for kicks, and it was louder when recirc'd. Just FYI, I guess...

It still has to let the air out at some point and hold it for the 9 or so seconds he is traveling down the track. That being said I agree it isn't the best thing but it can be made to work and work well.

Greddy Type-R and HKS SSQV FTW if you're looking for one that recirculates.
My HKS holds well at stock boost levels on my car, and held 25+ psi no problem on my friends EVO.

I would like to throw in my recommendation for the Tial BOV. It is a great piece of hardware, with an amazing and unique sound and has held 30 psi on my application with no problem.

Tial is great, but it requires extra to run it properly... Also doing a maf/t I have heard it causes problems with DSMlink users.
