Point of upgrading the BPV

[laloosh]

Just like the tittle says. What is the point of spending 200-300 dollars? Does an aftermarket one actaully do anything differnt besides make a differnt noise than the stock one? Call me a turbo newb but i never understood the point of upgrading it...so edumacate me. (hear ya)

Coming from a spec v like yourself i want to know also, But i think it helps with holding boost.

 

[CaSHMeRe]

the stock bov is plastic and made to handle stock boost.

any time you start pushing it and trying to increase boost, many times the stock plastic bov/bpv starts to leak and not hold boost as well.

most people get them for sound/looks. the only mechanical advantage is what i posted above.

so pretty much unless u raise the boost its a pointless mod when it comes to performance? I have a cpe intake and im ordering a cpe downpipe very soon. So my question is will a i/tbe cause the stock bov to leak? a i/tbe should not raise the stock boost levels it should just make them hit sooner in the rpm band right?

in who's opinion ?

a VTA BOV can be tuned correctly.

Lets see you push 23lbs with the stock BPV/BOV without it leaking.

Unless tuned, i do agree a VTA BOV is a waste of money, but once ur car is tuned and especially running higher #'s, it needs to be upgraded.

So inconclusion unless ure running some kinda of piggyback/flash that increases boost and bpv/bov is pointless and a waste of money when it comes to performance? Im not trying to hate on the mod, i just wanna understand how it works.

 

[CaSHMeRe]

yes. unless you plan on running higher boost, there really is no point to upgrading your bpv/bov.

yeah a VTA blow off is a waste.... agood bpv is not !
i notice much better throttle reponse and faster spool up with my forge.

not a waste if tuned correctly...

 

[SwampAss]

why not go with a diverter like a Forge 007? (assuming they fit our cars)

tuned correctly .......is not an option for us at the moment !!

not a waste if tuned correctly...

So are you saying a VTA BOV would be better than recirc valve on a MAF car or just saying a VTA BOV is not a waste of money? If its the first, then I guess I don't quite understand how losing metered air to the atmosphere is a benefit other than to make a lot of sound.

i have hks which is vta/recirc...works fine, i bought it because i will eventually increase boost and tune.
