Ok, so I'm corresponding via email with a guy at a tuner shop, and was asking if they had a Tial BOV. They do, but when he responded, he said there was battery relocation issue, and recommended a different one (HKS SSQV kit).

Now I'm pretty sure that the battery being in the back and the BOV being in the front, there wouldn't be an issue.. I google'd it, and the first page didn't return any relevant results, so I decided to ask here.

So what I'm asking is:

1. Is he wrong?
2. Is the HKS SSQV a better choice over the Tial BOV?

 

It sounds like he either doesn't know what he is talking about or he misunderstood you when you asked him about the tial bov. Cause I cant see how the battery has anything to do with it.

 

sounds kinda weird there man. dont think the battery has anything do with with any bov, hell do yourself on better and just use the stock bov

 

I'm guessing they are thinking of the Evo 8-9 instead of the X.

 

Ok thanks guys, question #1 is answered.. Now on to question #2 >.>

 

I would say no it isn't. Tial is 50mm which is much larger than the HKS. It works well and sounds good. I did have to use a 9 lb spring and shim it with some vacuum hose to get the tension just right though.

 

question number 2
i've heard alot of folks having trouble with the hks bov, but i still say stick with your stock bov

 

I have the HKS SSQV that's vented. No problems ever. I've never used the Tial but always heard that it's a very good valve, and I do like the sound of it. The HKS is very responsive and sounds good when it dumps at full boost, plus you can always change the sound by taking out the fin.

The thing I like about the SSQV is that you don't have to worry about changing springs at all and it's impossible for it to leak.

 

The difference between the two is the fact that the Tial holds higher boost more steadily than the HKS. I've had both BOV's and I'd choose the Tial with a 9 lb spring. (about 37lb boost holding capability)

BTW: I think he's just trying to get rid of the HKS in stock.

 

Please god don't get the HKS.

 

1. Yes, he is wrong. He is thinking about an VIII or IX, not the 10.
2. No way in heck a SSQV is better than a Tial.

 

Try a different shop.

Yes he's wrong, and the HKS sucks. Go with the tial.

 

Go with neither; the stock BOV holds boost just fine! Spend your money on a part that will actually make more power!

 

+1 on that. I asked several shops (AMS, Cobb, etc) via PM what was the best BOV for the Evo X and they said the stockers good up to about 450whp. After that, get the Tial Alpha Q recirc BOV

 

It could also be the guy was referring to the ralliart when he mentioned the problems.
