Drivetrain WMW Performance Blow off Valve -- opinions?
It used to be different but they are now the same.
I have this piece on my car with hybrid K04 internals and running decent boost and this part SAVED my car, and is SERIOUSLY a great piece! Everything advertised is true about it, and it really runs like a GEM! my stock diverter/bov failed on me majorly and was causing big boost problems and running issues, this piece REALLY does the trick for faster boost response and control.
AND it's completely stealth... i know for a fact that the dealer wouldn't even bother taking it off the car because they don't replace JUST that part... they'd just get an entirely new turbo for you and charge you WAY too much for it. so no the dealer won't bother with it at all... and as for pictures i have some that i'll post in a minute about the two side by side (as well as how terribly my stock one failed....)
and just to top it all off... WMW sent me mine fast as possible when i needed it... some of the best customer service ever!
a friend and i might dabble into trying some slightly higher tension spring rates for the bov but the one in it seems more than sufficient right now

Replacement from WMW

Two Side By Side... and just how failed stock is....

Excellent! Forgive me if this is an ignorant question, but does this affect mileage at all?
Also, I've heard here and there that these things can cause damage to engine in the long run that wouldn't have happened were they not installed. Any solid fact-based truth to this?

i personally have only heard of that issue with JCWs where some people have said when they track their car the valve isn't opening enough and is causing compressor surge... since this, as stated on WMW website, isn't an upgrade for JCW, i don't see it causing an issue... since the actuator is stronger WITH the spring, not just the spring, it is matched in such a way that it shouldn't cause any issue like that at all. unless you have one of Jan's JCW challenge tunes... that flutters the stock bov/recirc in such a way that it tries to keep as much boost in the system as possible without damaging anything (as i understand it anyway...)
hope that helped a little... but anyway long story short no it shouldnt' damage anything...
I took the oem out and compared it to WMW and I didn't really see the difference...they look identical...springs felt the same...anyway I installed WMW one and went for a quick drive and...I didn't feel anything different...
I'll update on this after drive to work tomorrow..

I see that u have 2008...maybe Mini started putting stiffer spring in 2009?...
So all it needs is a firmer spring?...did I just pay $60+ for a spring?...
Forgive my idiocy as well, but when would I notice the difference when using this piece versus stock? Most of my driving is highway with some spirited jaunts in between. Thanks to those that have an answer.
what difference? If it could close sooner and hold more id do it.
No bov/bpv will increase power

Just wonder what it will to to the spool characteristics and re spool characteristics like physically...
I wanna feeeeeeel it
