Mel told me she opens a word document and type in a word she is not sure of and it gives the spelling options. I just keep hacking away 'till I get rid of the yellow highlighting haha.

Back on topic, what are the benefits (if any) or problems with actually running the stock BOV and an aftermarket BOV at the same time? I think the aftermarket one would be run on the opposite side to the stock one.
Checked my grammar in Word and it said it was fine, so

Yup, noisy BOV's are in fact just rice. IMO anything that increases noise without improving performance is just rice (and irritating when they drive past your house at 4am)

BOV doesnt increase performance. So no advantage.
Not totally true there, Callum. A BOV serves to vent/release the backpressure built up by the turbo that doesnt get into the inlet manifold when the throttle snaps shut on gearchanges - and thus reduces the lag when the next gear is engaged and the throttle opened again.
So it does serve a performance increase - makes you quicker through gearchanges by reducing lag.
I agree with the "noisy BOV is just rice" sentiment - if the BOV is doing its job properly, it should be venting the built up pressure as quickly and as hard as possible - which should sound like a "whoosh" noise, not like a "squeak", etc. Think of it as breathing through a small straw as compared to a snorkel - the bigger the diameter, the easier to breathe, and the less noise. If your BOV is too small/not venting efficiently, then you get loud squeaks. So basically BOV manufacturers that market a BOV as "the loudest on the market", or by the sound it makes, are atually selling an ineffeicient/inferior product.
