"The BIG BOV thread" (Where all bov question threads get merged)

[DTR rex]

neither mod is really necessary. but if you are really adament on getting a BOV, then I recommend the Forge. Its nicely built and its one of VERY FEW bov's for the rex that hasnt caused problems. not to mention it sounds pretty nice. Also, you dont need a turbo timer.... the car is built to not need one.. Just dont race someone and then turn off your car immediatly afterwards

But, once again, if you are adament on getting a TT, then get the Blitz TT DD. Its a turbo timer with a built in digital boost gauge. atleast this way you have some sort of function coming from the part.

i recommend exhaust first..... but if you want something loud the TurboXS RFL BOV is what i have.. im running 2 washers and have had nothing but great results. i also recommend the silencer delete mod, and a panel drop in filter (perrin is what i have) and the TT is not worth it, we have a coolant based turbo, if you want electronic get an engine managemant ( like cobb...)
thats my 2 cents

If you are looking for a BOV that recirculates and makes the cool noise, check out the GFB Stealth. Its harder to find one, but you can adjust how much vents to the atmosphere and how much goes back to the intake. I have one on order. Once I install it I will let you know how it goes.

ok i want to know whats the difference between 50/50, 100% atmosphere or the other type of bov? which one is better? does it depend on your setup? what does this mean?!?!

[BrianH]

why do you need a BOV? are you running high boost or do you just want a noise maker?

[VSGTS14]

i think 50/50 is where half of it is recirculated like the stock one does, while half is vented..this is usually called a hybrid BOV since it's a cross of the two.

atmospheric means it's vented 100% and no recirculation

Search. This is an age old newb question that has been asked again and again.

But to get you on your way a 50/50 lets 50% of the air blow off to the ATM and the other 50% is routed back into your intake. A 100% vents all the air to the ATM . Good Luck with that search.

EDIT: Looks as though I was beat to the punch.

100% venting to atmosphere BOV's make your car run rich, as well.

Yes, although only very slightly and only for a fraction of a second. Not really anything to be overly concerned about though.

every set up i see that is running a tial bov has a fmic. i was wonderin can it fit on my tmic? i know i will have to weld it on. thasts not a problem. but will the gigantic size of it not clear the hood? also has anyone had anyproblems running this valve?

[silvscorp]

Anyone know what material is the BOV (like GFB, HKS etc) made of? I am thinking about scrach off the paint on it and repaint to another color (I have the GFB one). Also anyone ever done similar things like this as what is required to get the paint come out nice? Any special primer or paint is required?

Thanks

p.s for who ever is curious, I am trying to cleanup/dress-up the engine bay, and my bov has some scrach on it. Trying to paint it to red. I know the GFB has a red color but don' think it's worth the money to get a new one, plus the red GFB doesn't have the red I want.

thanks

Aren't they anodized?

thats what i thought

[silvscorp]

yes they are anodized, basically i am trying to remove that anodized oxide coating and just put on a regular paint. Wondering if that's possible. Under the coating, it's just regular metalic surface. I am just wondering what kind of metal is it made of and what kind of painting method can be applied.

[KieR]

just a quick question about my BOV. I had my greddy installed on my eclipse, and removed it before i sold the gsx. Now i want to install it on my wrx, and i was wondering where i can get the flange that will fit our cars for the cheapest price. Can anyone help me out there?
