Chatter on boost? Isn't that surge?!
If you are willing to spend 2 grand for the sake of a noise then EFI conversion would achieve just that.
Honestly I think that efi chatter sounds pathetic as its to high pitched.

Videos examples are fiesta's, dont know if the turbo size would make much difference or not? hopefully someone will shed some light.
Much better sound

more breathy and forcefull.

i took the dump valve off my cossie,although i love the sound i got very annoyed with it very quickly.
i think maybe more boost causes more chatter,or surge,or turbo stall or .....!

Turbo size depicts the chatter noise as well as boost level and engine size, usually small turbo equals high pitch (t25, t28 etc) and bigh turbo equals a more slower low pitch chatter, t34, t4 etc. the more boost you run the higher the pitch as a rule also.

Chatter is Turbo stall and is bad for turbos, it puts strain on the turbo and will shorten the life of it, why would you want that??
You close the butterfly and excess boost back up and pushes its way back through the turbo THE WRONG WAY and the noise is the blades chopping the air up. Now your turbo is stalled you have lost boost?? You dont want turbo stall

Also, Between gears, a d/v realeases all boost pressure so the turbo needs to charge the cross over again before power returns. I found My erst running 15psi has less "lag" between gears without a d/v.
The other thing, My Turbo is nearly 3 years old now, every day car, running 17psi, not even a hint of shaft play. So it cant be that bad surely?

You can get a nice bit of chatter on MFI. Just not really loud like EFI. Anything over 14psi iirc on mfi you can get audible chatter.
Will have to try and get some footage of my car another day. I actually prefer it to the sound of efi chatter.

Yeah but, clearly not a std frst is it? sounds completely different.
I'd be hacked off if I EFI'd my erst and it sounded like them.. or this

Its the difference between MFI and EFI that gives you the louder chatter. However I'm not sure what makes them sound so awful lol.
#20
The classic Cosworth Chatter is the king, but T3 EFi chatter sounds pretty cool 2!
MFi's dont chatter much as the airbox/associated pipework deadens the noise slightly, although that said its still audible esp when running some decent boost!
Obviously an EFi if fitted with a cone filter has no box/not much pipework to deaden the sound that comes from the turbo!

#21
so how can i achieve a slightly louder chatter from my mfi rst?, obviously remove dump valve,how about removed air filter and fit something mesh over where the cone would sit on the metering unit?
fit metal boost pipes????

#22
obviously i mean a sort of mesh that would stop crap gettin sucked in.
as i no the filter must dull the noise slightly aswell.
i would have thought with something like that on the metering unit and at least a bar of boost it should make it sound a bit louder????
