Just wondered what any of you think. I need to order one this week and not sure which one is better if either.. Looking at the HKS super sequential and the Tial 50mm. This will be on a single turbo car running 16-18psi for now but see 20+ in the very near future... Thanks

 

wow im gonna post in one of these threads

anyways

thats the one I would get holds alot and sounds great..not that stupid whistle sound....honestly no other choice besides this one once youve heard it

 

.

 

the tial is an awesome piece of work. the largest and best built blowoff in my opinion. but its not for those people who want something to make a lot of noise.

 

Is the Tial louder than the stock BOV...I don't want loud but the Tial is going on my car. I guess I will hear it sunday.

 

TurboXS BOV Type H-RFL

anyone care to guess what the RFL stands for

Real ****** Loud!

 

I heard alot about the HKS bov being very good. It makes a very loud noise though. Personally, I would get the HKS.

i have the turboxs H-RFL, it is reall loud, i come down my block sometimes and hit like 6.5k in first gear, then drop it in neutral and i coast the rest of the block in neutral, i get to my house and the neighbors are like DAMN, i heard that whoosh sound all the way when you were back there..LOL

 

I am not looking for the sound so much as I want good looking, well working quality parts!! I am going with the Tial.. Thanks everyone.

 

I've got the tial and I like it. Unfortunately I only enjoyed it for a day before my engine popped... From what I remember it wasn't too loud. I'm planning on 15psi with the new engine.

 

I've heard good things from HKS owners.

 

Hks SSQv for me since it is a pull type rather than a push type BOV, dont know much about the tial one but HKS said that the SSQV is good up to 28LBS of boost

 

we have run the turboxs rfl up to 38lbs of boost on our 500whp wrx

 

Tial

 

I have the HKS SSQV and let me tell I have no regrets.

 

HKS BOV and Tial BOV have different designs.

HKS BOV is a pull type BOV. It can hold as much as you want because it's the vacuum from the manifold right after you release the throttle opening up the valve.

The Tial BOV is a push type BOV. How much boost it can hold will depends on the spring it comes with.

Tial BOV has a larger valve so it can vent out more air. HKS BOV is kind of small so it's not really good for big single turbo.

I have used them both and I have found the Tial BOV to be better against compressor surge due to it's larger valve. But if you plan to run a lot of boost, you might want to consider the HKS one.

is that a typo? did you say 38psi???

 

just get the hks bov

 

not a typo... i did say 38

 

HKS is good i got it on two cars

 

lol nah i believe you, i was just in shock cause of the really high boost and only making 500whp on a wrx

 

just bought a tial
havent gone into the car yet

 

I'm not sure that is correct. The nipple on the top of the TiAL is connected to the manifold. The bottom of the valve is of course exposed to the airstream going through the IC pipe.

Therefore, the air pressure on both sides of the valve will be equal. However, the top of the valve also has a spring. The softest spring the TiAL comes with is 7lbs.

Taking the spring into consideration the pressure on the top will =boost+ 7lbs -restriction created by the throttle plates (which should be very low). The pressure on the bottom will still =boost.

Since boost +7lbs is always going to be greater than boost , the valve will not open under any boost level.

Agreed, it's a monster!

If you go with a TiAL make sure it has the 7lb spring. TiAL originally sold it with a 12+ lb spring, but went down to 9 and then a 7lb spring for rotaries.

I bought it because of its size and the fact that it is relatively quiet. As a side note, you can see the valve slowly opening and closing at idle, kind of like a giant animal breathing in its sleep

 

hks

 

oh crap
mine came with a 11psi spring ....
how hard is it to change the spring on the BOV
