vroooom ptssssh

Might here a little tiny bit of chatter but short answer not really

moesin2005

wants to be efi to chatter

Chris69

mfi can chatter but only at really high psi from wot i've heard

That's not true, the loudest chatter actually happens at low boost.

If an MFi car is heard to chatter, it will be slight and the best way is to run an induction kit, which will conversely be shit for performance. So, it's a case of what do you want? Chatter or Performance?

Mine did chatter the odd time, when I say chatter hardly more than a whoopoo lol but my turbo is pretty fucked...and need to be giving it tatties! as the turbo's got even more fucked It's not done it as much still holds boost tho 7psi

Chris69

i stand corected- only ever heard chatter on one mfi car and that was at 10 or so psi- car was running like crap with an induction kit on though
i just though it stood to reason it would get louder the more pressure the there was being used- my bad

Sorry, I didn't mean to sound so aggressive in my reply!!

I can understand your theory, the logical approach, I think the higher the boost and RPM, the more 'shrill' the noise, the lower the boost and rpm, the deeper the noise.

yeah mine shrills slightly,when its on da road! a slight sparrow warble tee-hee!stethescope needed tho!

Mr.T

Mines chatters to. running 0,9 bar. Don't know how much PSI that is.

edit:
Running open airfilter,stage 3 T3,and bigger intercooler. Don't know if it helps

i always thought mfis couldnt chatter as i was told a car chatters when the turbo spins backwards and as the mfi's have the non return flap underneath the air intake it stops boost for escaping back through the air filter therefor stops the turbo from being able to spin backwards and make the chattering noise.... cars that do generally chatter have an air filter straight on the turbo ie fiesta's and most rice motors

1.9 xr2 on 40's

my old erst estate chattered like a loon when comin off the boost softly, big cooler and a filter helped

i second that said by Christian and Beccy

the loudest chatter actually happens at low boost.

but never heard mfi chatter myself

The turbo doesn't spin backwards! It's the air that suddenly changes direction as the throttle slams shut and goes back through the blades the other way, hence the sound is the blades 'chopping' the air that is going out.

Mr.T

It doesnt really matters how is named or how its made. The sound is just

Dragsteer

remove air filter and will have chatter. BUT no smart option (or at least put some net ) because can damage turbo heavy
