Ep91 kid Posted December 27, 2015 Posted December 27, 2015 (edited) Just wanted to hear from other people still running the stock ct9, do yours whistle when coming on boost? Ibe just replaced the turbo because I killed the old one and both of them have a whistle when they spool up. I always thought whistle = dying turbo? Any info much appreciated CheersEdit: I'm running an hks air filter relocation kit if that means anything Edited December 27, 2015 by Ep91 kid Quote
dan106 Posted December 27, 2015 Posted December 27, 2015 Thats just sound of a spooling turbo id assume? Quote
Ryan_EP82 GT Posted December 27, 2015 Posted December 27, 2015 I hearba slight whistle out of mine but I assume its just spooling up Quote
Ep91 kid Posted December 27, 2015 Author Posted December 27, 2015 Good as long as it's not just mine lol Quote
crispyeel Posted December 27, 2015 Posted December 27, 2015 Double check all vacuum pipes etc as it could be a very slight boost leak. I had this issue after changing my turbo and manifold, drove me nuts for days trying to find it Quote
Maxep Posted December 31, 2015 Posted December 31, 2015 Yeah had the same thing happen to me, Had a whistle when on boost. Turned out to be the intercooler piping leaking. Other than that, I can only hear the turbo spool noise. Quote
StuDoc 72 Posted December 31, 2015 Posted December 31, 2015 If a turbo is whistling and thers no leaks then it means the blades are chipped normally. Quote
