how do u make a frst chatter is it just a decent induction kit

 

put a cone on it an no dump valve
obviously the more boost the louder it would be

 

it has a k&n cone now and dump valve just remove the gay valve ant its chatter away

 

Youre right just add an induction kit, my frst was standard when i put a piperx kit on-hadnt expected the 'chatter' but it was a nice surprise!!

 

sweet cheers peeps

 

does the same happen with an erst?

 

only on some

 

i thought chatter was an undesirable effect? back pressure hitting the blades of the turbo causing it to stop or slow down very suddenly?? the idea of fitting a dump valve was to eliminate that chatter and prolong the life of the turbo?

 

um which some?. or is just luck/unluck of the draw

 

The effects on an RST are minimal. It'ds only going to prolong the life of your turbo if you buy into the marketing bullshit. If you are running 30psi or more boost then these effects could be damaging but under this level you don't need one.

 

Hey take it you got it then?

 

lol @ Alex.

Peter, your standard MFI car won't chatter.

 

The red s2 mfi we had last year chattered

 

I knew it wouldn't be long before someone said something! Yes, ok ok if you run a decent amount of boost, it may do it, but it won't be like a frst as the metering head muffles the sound out. My standard MFI S2 does it a little bit...think it's got an air leak somewhere though!

 

My S2 does a bit but nothing like the Fiesta. Only reason I have chatter is I can't stand DV's

 

good, the answer i wanted
