[QUOTE=ScottFW;575333]Exactly. The rally guys do without BOVs because they want to eliminate lag as much as possible for better throttle modulation, and retaining pressure in the intake plumbing helps with that. QUOTE]
Srt of shooting myself down, but a BOV actually improves throttle response. Wihtout it you have a situation with rapid decleration of the compressor wheel when the throttle shuts, which requires the turbo to spin back up more than if a BOv was present. One of those weird counter-intuitive things. |
So my comp just did some pretty weird shit. Sorry for the newbish messed up posting. Wont let me delete.

Not agreeing with the argument in any way of supporting NOT running a BOV, but I do know this, Chrysler Conquest TSi/Mitsubishi Starion's did not run BOVs. Yet, this was a time when engine design overall doesn't seem to be very well thought out with those vehicles, anybody who has seen the fueling system knows what I'm talking about.

We don't have one on our 376rwhp monster |

Actually the Buick Grand National 3.8i turbo '84-87 didn't come with a BOV... and their turbos lasted well beyond 100K miles. They were automatic transmissions so maybe they were a bit softer on them....
Get a BOV from an Audi, Mitsu Evo, Subaru WRX or other factory turbo'd car and install one for next to nothing. They are there for a reason. |
I'd suggest a 1st gen DSM BOV as another cheap, reliable one. Nice and tight up to about 15-16psi, then can be modified to hold up to the lower 20's. You can find one in good shape for $30-40.

Funny this subject would come up because i was talking to one of the guys from precision turbo and they told me if i have a turbo with an antisurge cover and a manual gear box a bov is good for nothing. however he said with an auto you gotta have one did t really get a chance to ask why autos needed em and manual dont but he said with an antisurge cover theres absolutely no need for a bov.

That makes no sense to me. Autos dont need a BOV near as much as MTs do, the throttle plate does'nt close in hard shifting.

Im going to recirculate my BOV to my asshole

Many people I drive with dont run BOV either. They said the effect is minimal and worth it not having to worry about one more thing.. I have a big ass Tial BOV Brb guyz im gonna go un-install my wideband because it's just one more thing to worry about :hustler: |
Yeah, like the RX7 guys give a crap about their turbo lifespan when they wake up every morning praying for another day of functional apex seals.
|
I don't run on on the Miata and never ran one on my FD or Skyline.
And I track all of them. No extra shaft play has ever really come about from it either. |
