I have the HKS SSQV. I was under the impression that it wouldnt cause the issues it does, so i spent the 220 on it, but the issues are less severe with it.

The REAL reason i went that route is because its one of those most obnoxious ones you can buy ;)
It's Gumby's fault.

If you set it up as a bypass valve, it will work very well actually. Its not the *ultimate* solution, but its better than nothing.

ebay, for a 5.0 mustang

youll probably need to buy a 3" hump hose, and do some tpuppies of one of the tubes though

Gee, it's not like I didn't mention all that.  :p

If you want to deal with the issues a BOV causes with a metered system, then by all means..go for it.

I had no issues (other than not sounding "cool" ) using a BPV on the metered systems.

On the current SD system in the TBird....by all means ...sure as hell I'm gonna use a BOV......

What is the benefit to a BOV rather than a BPV?

BOV's can be less complicated in their installation due to the fact that they just vent to atmosphere.

On a system that is metering air before the BOV, such as a MAF application, when the BOV vents, it vents metered air, thus causing a momentary rich condition, which may or may not pose problems.

On a SD system, the air that is vented is not metered previously, and thus causes no issues.

A BPV recirulates the metered air back into the "system" after the meter, but before the turbo.  They are also usually quieter.

Are there any performance benefits of a BOV wrt a BPV with an application that vents metered air? It seems they're mostly for show [sound].

Nope....


Well maybe in extreme boost situations, but for the normal folks, no.
