had new stage 2 turbo and 31 actuator out on and set up, i took dump valve as it is gay,
and my car chatters when you give it some

 

kool funny but kool

 

didnt know it was possible to chatter?

 

i didnt think it could chatter because of something to do with the metering unit?

 

It will be a wee hint of chatter sound, nothing like the real sound you get without the metering head.

 

mine chatters on standard turbo just not as loud as efi

 

yea its not cossie chatter but a bit there quite loud to

 

Mine chattered a bit more than you'd expect for an mfi car,std boost and std turbo, think the turbo had a bit of play in it which may of helped

 

mine used to be quite loud on mfi

 

Same here mine chatters like a twat lol.

 

My zvh chatterd a bit on mfi @ 1 bar but nothing like now it's on EFI @ 1.5 bar :P

 

theirs a flap in the metering unit, and i think that causes it

 

wastegate chatter is caused by the waste gate,lol,the metering unit just dampens the noise as its normally shut

 

wrong im afraid

it's actually the turbine stalling when the throtle closes as the boost has nowhere to go so stalls the turbine.

 

indeed ur right its compressor surge no such thing as waste gate chatter

 

pmsl

 

Metering unit might be fucked too

 

better not be metering unit as it is a recon one from jamsport

 

nothing wrong with dumpvalve. i like my baileys

 

my old mfi used to chatter then dump thru the dump valve with a stage 3 hybrid on it

 

the dump valve was ok the start off with but got annoying for me i still got it so might put it back on in the future.

 

Mines on EFI + ZVH + T34 + -31 actuator + 24psi = Big Smile on face everytime i let off..

 

DV26 chump valve is the gayest thing since Liberace...

FACT

 

That Phils old car you've got mate?

 

It is indeed had it for about 4 months now..

 

fact? i must be gay then, coz i like mine

 

come on guys post up some vids of MFI chatters! I would remove my dumpvalve if people show me that i can have some good chatter on MFI

haha that sounds like anthony hopkins off silence of the lambs.

 

Hi mates!!

How can I get a wastegate chatter on my MFI Escort RS turbo S2??

Maybe I need a MFI TO EFI conversion.......................???

I like this sound better than the "psssssssssss" of dump valve.

if you want loud chatter you will need to dump the metering unit which means changing management

 

^^ which isnt as easy as just the metering unit

you'll need a fair bit,

 

Read the above posts mate!!
It isnt wastegate chatter, its the sound of the turbo stalling as pressure builds back up to the compressor blades, a dump valve eliminates this (well depending on your boost pressure) so if you want chatter the easiest thing to do is remove your dump valve and be runing above standard boost.

 

if thats to be i already know that

i was qouting the above post to me

 

I have chatter on 1 bar (averything else standard) but only if I take out airfilter. So I dont do this.

I hear before few weeks sound of my mate corrado turbo, he was parked in garage, so he rev it at about 2000 rpm and had loud chatter.

 

Mine chattered like fuck on MFi, proper loud...... it was also proper quick too.......





.....but it also did break soon after

 

ade: what did you do on engine? I have chatter on 1 bar but not so loud :S

 

Set it up with way too much boost!

 

to be fair mines on mfi 20 p.s.i boost 220 bhp and it chatters loud

 

someone here told that have standard boost and chatter on mfi. how?

maybe metering flap get "soft" ? So have little play , and let noise out. I dont have idea...
