Pig Posted April 24, 2006 Share Posted April 24, 2006 WTF is it that makes the noise, similar to the chirp of the dump /blow off valve. But not just a single chirp! Supraloopy may remember, when we were at the colchester meet the big single that came booting down the stretch. Any idea's? CJ's car was making the noise at bovingdon!

suprz_rz Posted April 24, 2006 Share Posted April 24, 2006 Recirculating dump valves make a multiple tsh.. tsh...tsh sound. More quieter than standard atmospheric dump valves though. Quote Link to comment Share on other sites More sharing options...

JamieP Posted April 24, 2006 Share Posted April 24, 2006 some wastegates vent back into the exhaust, some are externally vented mine vents behind my front wheel, its like a 2" exhaust Quote Link to comment Share on other sites More sharing options...
Class One Posted April 24, 2006 Share Posted April 24, 2006 You could of course do what Emin did (Suprattmyster) He installed a xspower external wastgate where the standard bov goes and everytime he lifts off he gets the wastegate chatter!!!

Pig Posted April 24, 2006 Author Share Posted April 24, 2006 some wastegates vent back into the exhaust, some are externally vented mine vents behind my front wheel, its like a 2" exhaust AKA the screamer pipe!

chilli Posted April 24, 2006 Share Posted April 24, 2006 i know the noise you mean and I used to get it on the integrale after the wastegate actuator was uprated (loved the sound too), I thought it was not a dump valve noise, but a turbo stall noise?

Ian C Posted April 24, 2006 Share Posted April 24, 2006 What the hell *is* wastegate chatter? Does it even exist? I hear the term bandied about a lot but I know the cause of all the noises on my car and the wastegate ain't one of them. I also find it hard to believe you could hear the wastegate opening and closing under boost... I think the noise is a low-boost BOV activation, where instead of a single blast it opens and shuts a few times a second, getting quieter with each cycle. Happens on boost-and-lift but not boost-and-cruise or boost-and-change-up. -Ian Quote Link to comment Share on other sites More sharing options...
Jake Posted April 24, 2006 Share Posted April 24, 2006 I thought what some folks call "wastegate chatter" was actually the turbo stalling from sudden backpressure when the throttle is closed. Quote Link to comment Share on other sites More sharing options...
chilli Posted April 24, 2006 Share Posted April 24, 2006 mine used to do it at full boost, on lift off all the time, it's like a rrrrrrrrr sound lol Quote Link to comment Share on other sites More sharing options...
