    You will need to upgrade to a big turbo and run it without a DV then you will get compressor stall which is sometimes confused with wastgate chatter. The Std turbo in your car is not strong enough to allow stall, the shaft will snap

    So i imagine if you spend around 5 k on the conversion you will get what you seek

    You need a splitter valve as the ECU on the 1.8t is programmed to have the air recirculated, and without it, the ECU will mess with fueling. The splitter valve feeds just enough air back into the system to make it work correctly and then enough to atmoshpere to make a woosh assuming thats what you want

    wastegates dont chatter, in fact, they dont make any noise at all.

    what most people call "wastegate chatter" is actually compressor surge. to achive that, get rid of your "dump valve" all together and youll have plenty of compressor surge.

    failing that, get an atmospheric DV (bad idea) or keep the normal recirculating one and fit a cone filter, youll hear it more then, but cone filters are a bad idea, so you lose either way just for a bit of noise. you could just sit indoors and watch the fast and the furious for your fix though if you dont want to make your car slower

    my wastegate chatters, but thats because its half broken and the pennys about to fall off :P

    As matt and mark say theres no such thing as wastegate chatter, its called compressor stall, and while it might work, i dont think the K03 would handle it for long. If you want to try it, then remove the existing recirc valve and block off the pipes, how long the turbo lasts though i couldnt guess.

    a friend of mine loved the sound of compressor surge, so much, that she had someone get rid of her dv all together

    maybe a year later it has been remapped, it chirps even louder (does sound cool) but the life expectancy of the turbo cannot be good when that air comes through the compressor the wrong way haha

    as for your wastegate... bad times!!

    I fitted a k+n 57i induction kit to my standard (apart from a re-map) 1.8t around 18 months ago and havn't had any problems at all and get a nice 'ptish' sound from it!! No noticable losses in power or heat soak or anything

    I feel a spot for my Fiesta chatter clips again

    As above though it's nothing to do with the wastegate. Audi's won't like chatter as teh system is MAF based and it will louse up the fueling and I have also been advised the K03 turbo's are quite a bit more brittle than the Garret item I ran in the Fiesta

    cool, how did you actually test for gains/losses then?

    I didn't, thats why i said no NOTICABLE losses. Still seems the same as the day i bought it nearly two years ago. I should imagine there is a small power loss but nothing of any significance
