wastgate chatter

[rx mad]

how do i get this on my fd3s i used to get great chatter of my 200sx but all i seem to get is the dump of the resic valves will it work if i take them of and block the pipes?

Can i ask a question why do you want wastegate chatter when all you are doing is shortening the life of the turbo\'s.

cos it sounds far better than a dump valve and im sick of pitsssshhh every time i come of the excelerator

[kev-yorks]

No problem mate if you loose the dump valve then you should get the chatter you want how loud it is will depend on set up. The chatter noise you hear though is a reversion of flow going the wrong way over the turbo compressor blades this puts stress on the shaft with more likelyhood of turbo failure.

Put antilag on your motor and a ignition based rev limiter you\'ll get a wonderfull collection of pops bangs and massive flames. Don\'t know how long the motor/exhaust will last though:2eek

Get a CD of the chatter and play it loud!!!
Then you have the sound and the Turbos are safe!

There is no such thing as wastegate chatter - all you are hearing is the distress of the turbo stalling. It\'ll sound good until the turbo falls apart and you need to replace it. Which won\'t take long if you allow it to be stalled continuously.
It also reduces throttle response, causing a longer delay in spool up time, compared to running with a dump valve.

Personally, I always thought that wastegate chatter was a chav calling card :Giggle but maybe only on a nova or corsa :WaveBye

mine is loud and i love it..been on the car for 4 years with no problem at all, although i dont go out and floor it all the time..:3gears-rh

Tony, this is true apart from the throttle response !

I don\'t care what anyone says drive a car with a dump valve then drive one without, the car without is soo much more responsive. The dump removes all pressure in the intake system so when your throttle opens again the whole intercooler and intake piping systems needs to re-pressurize.

I had no problems never running a dump valve on my cosworth and the turbo was in good condition after i removed it.

[TonyC]

Throttle response after dumping is dependent on where the dump valve is placed in the system if I remember correctly.

Compressor stalling does place a lot of stress on the turbo, you may have just been lucky with the cossie. (Mind you, if it was a cossie it probably blew up every other week anyway :chat )
