My 7 and I went out for a little drive today. After doing a 23psi run, I blew the little O ring in my Greedy Type R bov out again. (not the diaphragm thingy.) This is the second time I had it happen to me. I have the point where the bov releases adjusted pretty firmly, but not overly tight. I have it set where you need to be somewhat aggressive into boost before it will blow off. Anyone else have similar issues?

 

No one?

 

Suggestion, use a real BOV. Especially if you're doing anything over stock boost levels.

Might I suggest a Tial?

 

I've never heard a negative comment about the R model....a couple years ago this is what I was recommended by numerous people. Do you have experience with it failing or what?

 

Throw it in the bin. AND DONT USE ONE PERIOD.

Waste of space, time and metal.

 

Don't use a BOV? Explain this.

 

I'd like some solid reasoning/info why I should just bail on the bov, or bovs in general. Convince me otherwise with solid info, not by just telling me to do it.

 

700rwhp. 35psi. Turbo still in excellent condition after 6 months. And before that was making 500+rwhp on 30psi for over 1.5 years on the same turbo with no problems. Turbo in as new condition.

ALong with the long list of customer cars i have built/tuned with no bov and that have been reliable with 0 turbo failures. Not to mention better response between gears and less complication and 1 less componenent to fail.

 

Can you do that with the stock twins?

It seems that BOV was invented just for profit and annoying sound. Arguments, that it is there for preventing of surge are BS. Its really just next useless thing, that cost money and can damage turbo by overspeeding if not sealing right.
