Whos running a BOV?

[robertf]

I've always hated the sound of the wastegate slamming closed on decelleration. Will a BOV solve this?
Any disadvantage to a BOV on a GN? Of course I'd need up pipe designed for one.
Thanks.

Edit:
Did my search. I get my answer there. Thanks.

Yeah, I run one for that exact reason. Here is mine.

Funny thing is I see I asked the same question back in 2010. How embarrassing.

Im running a turbosmart bov and it doesn't sound like an import . No more surge part throttle at 24 psi

I'll assume no vendor sells a 3 inch up setup for one? It needs to be 3 inch for me. For SLIC.

I acquired a atr BOV for super cheap . So I'm runing it . If I didn't get it I would prob not be running one

 

[turbobitt]

I'm running a BOV because I plan on turning up the boost well past 35 PSI and don't want to back the compressor nut out.

The noise is compressed air coming back through the turbo when you lift.

A bov will replace the horse sneeze with a quick psh.. They are popular on stick shift cars. I like the horse sneeze.

Except the horse sneeze is the sound of the compressor stalling. Having it suddenly come down from 100,000+ RPM and even spin backwards is hard on it. And you get monster lag if you lift and then have to get back into it.

 

[TurboBob]

I doubt it spins backwards (anyone have real data?), but the flow reversal is hard on the thrust bearings.

With lots of boost and big turbos and such, when you drop the throttle there is a huge pressure spike that can split intercoolers and blow hoses off.... Thats why I run one....

making them work smoothly when you run a MAF is a little tricky some times, but with speed density they work fantastically.....

So Bob is Speed Density have better overall drivability on the street over MAF? I know I'm steering off topic in my own thread but this has actually crossed my mind before.

with a good tune, they both run well. when the tune is off, the SD stuff is more tunable, just because we have laptop access..

with a MAF, getting the BOV adjusted right so you don't get hiccups in the driveability takes a little bit of messing around.

Sometimes with a MAF if your turbo is prone to surging at part throttle you can have driveability issues where SD would not.

I run one but have it plumbed into my MAF pipe. Doesn't affect driveability at all.

Thank you Bob.

That's a pretty neat set up but not much different than coming back through the compressor. You still run the risk of the maf thinking it's intake air.

Just for the record there is no reason other than "don't like the noise" to run a bov on a turbo buick.
I confirmed with PTE years ago as well my own experience. Never has it hurt my turbo.

 

[TR Custom Parts]

How can the MAF think it is intake air if it is after the MAF?

 

[jbaker]

I recirculate mine.

The maf will read air flow in and out. It gets to be real annoying when you get a big front mount and all that air comes back through the maf. You can feel the stumble in sync with the compressor stall. Back when I still ran a maf I ran ls1 maf in my up pipe "blow through" and eliminated the problem.

So it may or may be effeting things for you guys. I never tried this method.

Do the afr's peg rich when the bov is activated?
