drew 007 Posted July 19, 2010 Share Posted July 19, 2010 The "chatter" you are referring to is (turbo stall) witch is no good for your turbo mate,but if you want the noise go for a turbo with an external waste gate Quote Link to post Share on other sites
BAZ2CRAZY Posted July 19, 2010 Share Posted July 19, 2010 Remove bov, block holes=Pigeon in your glove box.Mitch Quote Link to post Share on other sites
gtmuzz Posted July 19, 2010 Share Posted July 19, 2010 Literally block off the bov and 3mm pipe job done mines chatter very well, even better now ive got a fmic! it dumps at high boost and chatters on low Quote Link to post Share on other sites
Steve GT Posted July 20, 2010 Share Posted July 20, 2010 The "chatter" you are referring to is (turbo stall) witch is no good for your turbo mate,but if you want the noise go for a turbo with an external waste gate to be honest id say thats an opinion and not fact. mines chattered from day one no BOV or dumping just 100% pure chatter and my turbos as strong as ever. its a common misconception that chattering is bad for your turbo@theminiguru- try putting your foot down a bit, getting the turbo to spool up then instead of lifting the clutch to get it to dump, try lifting off a lot slower gently feed the pedal in and it should chatter. will take a bit of practice on how slow etc to do it but my blitz suoer sound BOC used to chatter all day long doing thisQuick lift of clutch=Dumpslow release of clutch= Chatter Quote Link to post Share on other sites
lukEp Posted July 20, 2010 Share Posted July 20, 2010 X2 I check my turbo once a week for play blade damage and I run pure chatter no bov no recirc valve everything blocked off and it's been fine so far. Quote Link to post Share on other sites
BenV Posted July 20, 2010 Share Posted July 20, 2010 the easyest way to get chatter with one of the dv's is to fit the 1bar plus or the red spring to it. chatters like mad just driving about but when you give it the beans it dumps quite nicley Quote Link to post Share on other sites
Dave@TM-Developments.com Posted July 20, 2010 Share Posted July 20, 2010 The "chatter" sound is the compressed air having nowhere to vent, therefore returning through the turbo and and trying to reverse the motion. This a not much of a problem on a decent turbo but can be on the CT9 as it is "not the best" in terms of build Quote Link to post Share on other sites
Lukew360 Posted July 20, 2010 Share Posted July 20, 2010 The shorter the air intake pipe the more chatter you will hear, with my blitz dump valve I get a good dump sound when I back off the throttle sharp, and chatter when letting off slow it's pure win!The noise comes from the waste gate opening and shutting as the air pushes its way through. Just sort of flutters. Quote Link to post Share on other sites
Lukew360 Posted July 20, 2010 Share Posted July 20, 2010 Simple quick fix for you I would say shorten the air intake pipe, when I did mine the air filter fitted on the straight pipe just after the distributor cap. Just before the "S" bend up to the standard air filter box. Quote Link to post Share on other sites
Carl. Posted July 20, 2010 Share Posted July 20, 2010 mine never chatters. got hks ssqv. Quote Link to post Share on other sites
Glanza_cl Posted July 20, 2010 Share Posted July 20, 2010 The noise comes from the waste gate opening and shutting as the air pushes its way through. Just sort of flutters.No it doesn't, it comes from the compressor blades as the air is forced back through them. it doesn't stop the blades or rotate them back round as some people seem to think it mealy 'stalls' them slightly, slowing the rotation chopping the air as it passes back through giving it that 'chatter' sound.As above if you want it, simply remove the bov altogether. if you want a bit of both get a bov with a harder spring in so it will dump on full boost and chatter on soft throttle.Compressor surge does damage some turbo's... you guys are all lucky that the ct9 are reasonable robust. Mr2's had a CT20b that had ceramic comp blades... try stalling them and the blades will crack and brake off, bad times. But most new age turbos or hybrids wont have any problem with a bit of comp stall Quote Link to post Share on other sites

jezza Posted July 20, 2010 Share Posted July 20, 2010 I wouldn't fork out for a stiffer spring until you try adjusting the current spring tension by tightening the adjustment screw on the top. Quote Link to post Share on other sites
Josh@TunerLifestyle Posted July 20, 2010 Share Posted July 20, 2010 why dont you find yourself a chatter box? you can find them in your local pub after afew drinks Quote Link to post Share on other sites
