Why Doesnt My Car Flutter ???

[TiNTiN]

i just recently installed as 600x76x300 intercooler on ma car yesterday i took it out for a test spin everything goes fine but how come i dont get a flutter noise i hear wen other people put on intercoolers ?

flutter doesnt come from the intercooler. flutter comes from the bov being too tight or not having one and the air goes back and hits the turbo blades and gets chopped. the intercooler will make it echo more but wont make the flutter noise by itself

Just block the black hose that run from your BOV back into the intake ( not the tiny vacum one ) then it'll give you heaps of flutter.

flutter= bad it will cause the turbo damage after a while

get an external wastegate

[EVL032]

just put a metal plate in the wastegate and take it 4 a drive and u will have flutter just open the two bolts and slide the metal in therefore blocking the air and making it return out the air filter

[timbar32]

some people are very confused concerning wastegates and bovs...... and why do you want a flutter noise???

buy a VL Turbo

Only flutter I've heard is on a VL that didn't have a BOV.

Wastegates are used to control boost on the exhaust side. And they don't flutter. If they are not redirected back in to the exhaust they are known as screamer pipes as that is what they do.. Scream!

Having no bov on a VL running no IC and std boost is fine. Once you begin to fit intercoolers and up the boost their is more air in the system which needs to be vented some where otherwise it will eventually cause damage from stalling the turbo when you lift off the throttle.

yea, i don't see why a wastegate would have anything to do with fluttering.

I think you need new tyres and maybe a new bodykit, neons too, that should do the trick (only kidding )

Aren't there some BOV's out there that actually do their job AND make a flutter noise (the release of air into atmosphere, not back pressure)?

[nitemare5]

Those are usually the adjustable type BOV's where the owner/workshop has tightened the BOV so that it will remain shut until higher boost is attained, therefore 'fluttering' at lower rev's and venting the air at higher revs.

And the award for most insane post of the year goes too......

If you block the wastegate your turbo will have no boost limit, and bye bye turbo.

What you want to do is tighten the BOV so it does not go off OR it goes off with the BOV thlutter

external gate with screamer pipe ... will flutter

who wants to pipe an external gate back into the exhaust
