Tial 50mm BOV - Focaljet

**IslandFocus** · 11-29-2007, 08:56 PM

Does this BOV come with the mounting flange and clamp? Also, would this be too extreme for a Focus running between 15-20psi? http://focus.c-f-m.com/index.asp?Pag...OD&ProdID=1443

I can answer one of your questions and that is the extreemness wich its not. Your prolly thinking along the lines of wastegate mm and those sizes. BOVs have a diffrent theory

So the 50mm Tial will work fine in my application then? I was looking at the Tial and the Greddy Type RS. The reason why I asked about the Tial being too extreme is because I saw a video on youtube where the Tial caused some surging at low boost levels. It seemed to work fine at bout 20psi though. http://www.youtube.com/watch?v=tXqgTtHECnk

Who is tuning your car? I belieave the TiaL is adjustable as far as tuning goes. Also that could be a lot of things not just the BOV that chach prolly has something else wrong with his car. Im not 100% we will see what William can add. I do know that there are a lot of people who reguard the Tial as the best.

I have also heard good things about Tial products. However, I haven't seen any turbocharged Foci running them yet. I've narrowed it down to either the Tial 50mm or the Greddy Type RS 40mm. I haven't made a decision on who will be tuning it yet.

Tial makes excellent products , you choose what type of spring to run based on what your engine produces for vacuum. For example (off the top of my head) 14in/hg - 17in/hg use a 9PSI spring. The surge your hearing from the Subaru is the due to the fact the spring is too much/tight. You may get some surge at a very low load but should be nothing like that video. BOV must be set correctly for it to work right. Also I'd be careful with the Greddy RS I know a few guys running them with no problems and others running them and they leak. I for example am running the Type S little different then the RS but not much and have had some problems with it .. I will be changing to the Tial soon. Hope this helps!

Thanks for your input! Very helpful!

CFM, do you have the Tial 50mm BOV in blue? Also, this does come with a mounting flange correct?

**boostedzx3** · 12-02-2007, 09:32 PM

I've been running the TIAL 50mm BOV setup at 8psi for probably close to 3 years now. I have yet to have a problem with it, it works great.

**IslandFocus** · 12-03-2007, 06:18 AM

Thanks! That's the kind of feedback I was looking for. What spring did you use?

I forget by now I think the pink one.
