mikey4410 Posted August 10, 2013 Share Posted August 10, 2013 (edited) hey guys, whatever this problem is its affecting my fueling a bit. i have developed a screaming noise when coming on boost on my ct9 (same as noise as when u pinch the neck of a balloon on both sides and let it down) and i have no idea of were its coming from at all. my fueling has gone lean because of this im pretty sure ,so i am thinking its a boost leak tbh. i am really stumped on were to go from here as all my brand new boost pipes are tight and i just dont know what to do.

Sefton-EP91 Posted August 13, 2013 Share Posted August 13, 2013 I know you said you have sorted it. You may want to just check the bolts that hold turbo to manifold. I had this same issue with mine. Tighten up and now its all good Quote Link to post Share on other sites
Ep'd Posted August 13, 2013 Share Posted August 13, 2013 Had this on my Subaru sti on high boost. You know what the noise disappeared on low boost but reappeared on high boost!It was the top mount sti Intercooler had popped and it was screaming like how you explained!
