Its hard to get a straight answer. Your reference says the turbo stalls resulting from the flutter.

Are all those turbos ruined or are they still boosting up some 20 years later...

Donating Members 15,637 Member For: 17y 11m 6d Gender: Male Location: Melbourne Posted 18/04/08 03:50 AM Share Posted 18/04/08 03:50 AM Yeah I know mate, the thing is I went on the same quest a while back and didn't get anywhere.There a lot's of people with all different bovs and lots or people running no bovs, everyone is going to tell you their setup is best to justify why they have done it. My opinion is bovs are better for the engine, but that is just my opinion and not based on fact. Maybe if you do some research on other turbo forums you might have more luck or even get in touch with Garret or HKS direct and see if you can get a bit more info from them.If you do find any factual evidence that proves either theory please make sure you share with fellow members so we might actually get somewhere in the debate.

our06t Mmmmm......BOOST Member 3,135 Member For: 18y 4d Gender: Male Location: central coast Posted 18/04/08 12:34 PM Share Posted 18/04/08 12:34 PM . The inlet charge of air is arguable warmer than that of the plumb back boost dump as its now vented to atmo (the cooler after intercooler air is lost). The stock Bov does not vent enough air, hence the flutter that continues (although less than no bov)even though the air has been through the intercooler even on the best set ups , it's still a few degrees above the temp of the air coming in through your intake Link to comment https://www.fordxr6turbo.com/forum/topic/44594-gimme-a-straight-answer-4-questions/page/2/#findComment-661280 Share on other sites More sharing options...

Other threads say the pressure of the air causing the flutter is sweet F all and wont in any way damage the turbo. If it slows it down, its still negligible..both sides of the argument are unfortunately correct!Why didnt VL turbos run BOV? Are all those turbos ruined or are they still boosting up some 20 years later...our cars do come with them... does that give you any clues as to whether to use them or not??I've seen plenty of VL's with bov's, does that show indication of purely a noise intent?
