Honestly, I have no idea. I was expecting a some sort of roar on the straight away, but the car seemed to be decelerating at that point in the video.

This does not sound like the greddy, have it on my big turbo sti that is now externally gated. The greddy is a straight rush of air.

There is a mobile phone app where you can listen to the greddy BOV if you don't believe me go dl it.

I have had a turbo on my car for the better part of 5yrs, if I wanted to listen to a BOV, I would just go start my car. If your WG is fluttering and it's the most noticeable sound from the car as it decelerates, I would have to ask....what's wrong with your BOV...lol. Your car is not functioning properly if the WG flutters sorry...

PS...what's in the video is not WG flutter, it's a BOV. I was just guessing on it being the GReedy, I don't remember what the GReedy sounds like off the top of my head.

Nvm. Sorry. Found the vid.

[Infernal]

definately sounds more like wastegate flutter rather than a bov/bpv - regardless.... TURBOOOO

Now that I remember, My old HKS BOV would flutter...

BOVs don't flutter. Neither do WGA. What you are hearing is compressor surge.

i leave you guys for an hour and i come back to two pages of stuffs.

btw android > iphone. android has flash.

we all know comp surge is flutter they are just expressing which BOV's cause this. i personally think it sounds like an RS or RZ bov.

[KidWonder]

I think that's the black FRS that Ken Gushing was standing next to a few weeks back.

[Syldrin]

wonder if that black one is the greddy car.

[VenomRush]

"Fluttering" = Compressor Surge = You're doing it wrong (or you're doing it in purpose ).

A BOV's sole reason for existing in the first place is to prevent compressor surge. If your BOV is allowing compressor surge it's either sprung wrong, connected wrong or is just a worthless POS that everyone thinks is amazing because it's from Japan.

The HKS does flutter at low boost. Could have been comp surge, but it was at very low psi (1-2). At high boost it has the normal pssshhh.

hard to say if thats a bov, or if it's a result of a monster turbo still in it's newborn stages.

I run twin external gates, before that a single external gate....never have I had a Wg flutter.


Anyhow, back on topic....in either case, the car is boosted.

This /\ and

Flash is dead thats why the video was HTML 5, android is a laggy pos rip off of iOS and you know it and if you had Siri and asked "what makes a turbo flutter" she would have stated the answer almost as well as Old Greg.
