Hey guys

Just a question out of curiosity.

Just for fun to see what it sounded like, I took off and blocked the vacuum line to the BOV to see what it noise would come out. But all i got was the standard gush noise through the pod filter. Last few cars i did this with I got the "fully sick VL turbo flutter" :P.

What does this actually mean? If there a leak or issue somewhere? Stupid topic, i know but got me wondering.

thanks!!

Removing the vacuum line will help keep the valve closed. Whether it leaks is another matter.

no the pressure in the intake pushes the valve open because it is greater then what's above it

Actually they're not that bad, a bit of molly lube on the stem of the valve helped my stock rb20 recirculation valve hold close to 30 psi

I've had a few, i noticed it on all. I tried a few things like what turbosmart suggest.

I am using an automatic, so it could be more pronounced because of this.

Nope. Boost pressure from the manifold helps keep it closed.

Removing the line makes it leak on boost, meaning the turbo has to work harder.

Oh shit I have, bruh youse need to take off ya stock bov, cut up your favourite aluminium can and make a blanking plate using that. Then drill two holes and sandwich it between your BOV and BOV 2x bolt flange.

Fully sick ulleh, dose for days and make betches drop their panties

I understand what you're saying, but the vacuum created when the throttle plate closes acts against the spring in the valve to open it, remove the vacuum line and the spring pressure alone is enough to keep the valve closed, or should be.

When I replaced my turbo I made up a pvc plug and pressure tested the intake, after I lubed the stem it easily held 20 psi

    • Block bump. $400. As above cyl 6 needs bore or sleeve.
    • I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.
    • I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.
    • From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.
    • They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
