i know where chatter comes from air rushing back through the blades, but my question is what makes different pitch/sound of chatter. Tried a few different setups on my EFI escort. Some give it high pitch some give it long loud low pitch

any ideas, i know alex ZVH is chatter box he looks to have a metal pipe leading to the filter with no bends etc, but he does certainly get some loud chatter!

the best on mine i have found is a curved silicone pipe leading to a filter.

anyone else views

Why would you want to make the annoying noises LOUDER?

Windle

to cover up my rattly cvh engine

I should think a metal pipe from the turbo straight to a air filter, with nothing at all in between them, is the way to go (ie no metering unit or anything)

Windle

thats what i was thinking, a mate dropped a 2.5 inch metal pipe. I have that joined to the turbo then to a small air filter. This changed the chatter to a low pitched noise, sounded well but not the loud high pitched that i have with the crap silicone hose

i changed from cone filter to airbox and the sound is different....its quieter but higher.............more like a rally car now....grown to like it more

Windle

this was the one i have just tried

2.5 inch pipe small air filter



gave a more of what a toyota supra chatter sounds like if you get me not very high pitched but nice

this one is more like 3 inch pipe and a big cossie air filter again 3 inch trumpet. This was not chatter at all, more of a flutter but very loud and seamed to go on for ages



just tried this one and it was pants! not loud and no chatter at all just gay fluttering



this is the best i have found





small bend going into an old made up filter with big to small steal pipe

this gives off nice chatter so is it the curve or filter style that does it

The shorter the pipe from what I remember makes it better

Windle

but this one was rubbish



and its a short pipe

Then why don't you shorten the one that makes the good noise or stop being a tart and leave it as it was

Windle

i dont want to shorten the pipe in case it goes wrong, then its in bits

if i know it will work then i can make something up proper

just being greedy, at 11 PSI the chatter my current setup uses is quite good i think, maybe i am just lacking some boost

nilrem

i guess the bend must echo the sound, acting almost as an amplifier, and the silicone will keep the sound, as metal will vibrate to the sound, almost damping it... so that must be it... the cone on the end will possibly help amplifying it aswell...



why not try putting the air filter into an acoustic guitar?? that seems to apmlify things

Windle

no room for a guitar sorry

suppose thats why all cossies do it then, they all have a 90 bend right off the turbo

nilrem

mega phone on the end of the filter?

i have a k+n std induction kit on my cossie and the noise is lovely and high pitched i think

i put a large induction kit and it went really quiet and deep and didnt like it

im sure its also down to airfilters aswell

just had a new pipe on mine aswlell which is slightly larger diameter and it has made a little difference but nothing major

Windle

so could be down to filters too lol

i will have to put 20 psi through it see what it sounds like then

boom i would think

So whats the diference between chatter and flutter then??? i just thought they were two different ways o describing one noise

4x4

I love the noise

Windle

i'd explian chatter as high pitch load noise similar to wheel spin lol ?

flutter more of what a t2 on a fiesta produces not high pitched but its deffo there?

souds like u just need a mans car with proper boost..............

Windle

its not how much boost you have, its what you do with it that counts
