How To Get Flutter Noise ???

[Evil_Mx6]

Hey guys, i just recently purchased a Vr4 which i am more than happy with, previous cars been a mx6 turbo x 2 , Rs Turbo liberty and now the happy Vr4
I am just curious as to how i can get the flutter noise from the car ?
my car is automatic and the only noise it will make is just the factory blow off valve doin a small whoosh, My couisin and i blocked off the factroy bov and tried but it done nothing.....
could it have somethin to do with my AFM ? mine is the big black cannister in the engine bay.

Any help would be great since a dropping a dose/ cooler is always FUN 8)

take off the air box and fit an aftermarket pod. but it will only be a little flutter. you want big flutter get a bigger cooler!!

Although it creates compressor surge, the best way to do it is to remove the factory b.o.v, and run no b.o.v at all. Also, install a pod at you'll get your flutter.

Did you buy BlondieVR4's 2-tone VR4??

thanx guys, if i take the cannister off there is already a k/n filter installed which is round like a pod, but the only way it gets support and a seal is when the cannister is on and covers it, if i take the cannister off the filter is just gonna drop, how do i go about fixing this ?? since the afm is connected to the big thin with the cannister ??

and yes i did end up gettin blondies vr4
for an automatic i am more than surprised at how fast it is. Not as slow as i though....and my RS was damn quik...

it'll do the same job of killing your turbo as flutter will

The AFM is the biggest killer of the flutter noise... If you want the mad flutter noise your only choice is to go with an Aftermarket ECU so you can remove the AFM and run a MAP sensor...

Its a mission but geez it sounds cool... 8)

Flutter isnt exactly healthy.
Ok at low boost.
i pity the fool who has full flutter at full boost.
Your Killing your turbo......

I know this is going to start an argument - but most of that hype about flutter damage is propaganda put out by BOV manufacturers. The only real disadvantage is that the turbo stalls - meaning that you have to spool the turbo again after changing gears... Whether this is a problem - or if it affects a 1/4 mile time by even 0.1sec is up to the owner of the car. But all of this aside - you have to admit that it sounds infinitely better than a BOV.

how does a bigger intercooler create flutter?

anyway... as the other guys said, put on a pod and either tighten the spring on your blow off valve or remove it altogether.

LOL
no its not

check out the compressor wheel of a VL turbo after its been fluttering on 30psi for a few thousand kays

oh wait, you probably wouldn't have a clue...

what would happen to the compressor wheel? :?
i would have thought it'd be the bearings and shaft that would suffer...

 

[GSRSOL]

well thats a bit blunt now............. :lol:

all you have to think about is that flutter is causing the turbine to spin in the reverse direction/ normal direction very quickly, it wears out all the seals and bearings quicker.

if you played with the compressor wheel, you'd see that the bearings were fucked..? also, the wheel would cut you

I ran it fine with my old 16g.. no problems at all.. and i think Jez is right.. its all marketing.. maybe it has a lil effect on life of the turbo but seriously it doesnt phase me. Im currently running no boz at all.

yes jon
im sure if we spun you around at 10,000+ rpm
then suddenly turned you around the other way, you'd be fine too

 

[JSTYLE]

a turbo goes up to around 150,000RPM!

ive spoken to heaps of turbo guru's... why do you think all HKS drag cars dont run bov's ? etc.. there must be a reason behind not running a bov.. just have a think.. i was going to put one on my car recently but i was told that it wasnt necessary..

i spose each to their own.. just giving you first hand experience

I would say that a busted turbo on a VL would say more about the owner than simply no BOV. It is a VL after all...
