All i need is a BOV for my Turbo project ( fianlly almost there). What do you guys suggest? I'm leaning toward the Tial 50mm. Also I have seen the BOV's installed on either side of the intercooler piping.. which side is better? thanks..

I put one on each side of the intercooler.

Gonzz,

Your car is looking good.

I went with the Turbonetics raptor BOV. You can pick them up from Jegs. I have heard excellent things from the Tial 50mm though. Every review I have read on it says that the machining is flawless.

As far as location I have heard a couple things:

1. get it as close to the TB as possible
2. Get it as close to the turbo as possible

I placed mine as on the TB. You can see the picture below for reference.

I am interested as to what results crazyrx7 has though. Do you have any pictures?

i think the reasoning behind having the bov on the throttle body side is to prevent the boost leak that could happen due to the pressure drop across teh intercooler. Also, the compressed air wont have to change direction to exit through the bov if it is mounted near the throttle plates, which means faster reaction to the throttle closing.

 

It is about the reaction time upon closing of the throttle. The closer the BOV is to the throttle plates, the faster it will react and let out excess air charge. Just think about it. All of the pressurized air will be sitting at the TB when you let off the throttle, would you rather have it exit as close to there as possible or all the way back by the turbo? That's just how it was explained to me.

And I have personally used the GReddy Type S, Apex'i twin chamber, TurboXS type H, Blitz DD. I now own the Tial 50mm and I don't plan to ever change away from it. It simply flows more than any other BOV I have seen. It may not have the "cool lazer sound" that some of the others do, but I'd rather have the performance instead of a cool sound. Just my .02

I like the Tials they are a very nice unit. Closest to the TB is best spot. If your in need of or want the Tial unit let me know.

 

One more for the Tial, had one on my old setup, and have another one on the new. i wont stray from them either. Old setup pictured below. Buy one from Sean

 

tial makes good stuff, good wastegates and bovs that hold high boost.
+1 for tial

 

Bought a Tial 50mm yesterday..

 

Now you just need to get it mounted up right next to the TB and you'll be good to go. Congrats on purchasing one of the best BOV's on the market. Out of curiosity, where did you get your BOV from?

Got it on Ebay... 219.00 shipped.. got the 11 psi spring
Should i install the BOV like this pic or on the same side but on the intercooler pipe?

 

If you have room just do it like the picture.

Yeah, I would say mount it up like that either on the intake elbow or as close to it as you can. Not a bad price on the BOV either.
