I have a ct26 upgraded (60 Trim, no clip), and it sounded alot like a jet(Rushing Air) when I boosted. Now after installing my 550's and Lex AFM, and raising the boost to 15 psi, it sounds like a diesel(Really high pitch). Is this normal? I really hope it isn't death whine, I mean it hits boost so fast and holds it. I can even loose traction at 60% throttle in 2nd gear. Let me know what you guys think.

Since i'm running basically no exhaust, my car sounds exactly like a semi. The turbo is extremely loud and does sound high pitched like a diesel. The death whine on my old turbo sounded more like a supercharger. Sounded like a midget was behind my dash going "wooooooooo".

Hahaha, well the turbo is high pitch like a semi. DBSupra sent me a couple vid and sound bytes of death whine. Mine doesn't sound like any of them, we thought maybe an exhaust leak pre turbo. I am going to check the main bolts and see if that could be the culprit.

Well I checked most of the mani nuts I could get too, and they were all tight.

I don't think so, timing is at 12 BTDC, car is running very rich too, and I never use any other fuel but 93 from newer gas stations.

Turn your timing down to 10?

any turbo you up the boost on gets a louder pitch noise because the turbine is turning faster you are fine

It's a bad thing? Haha, kidding, people have asked me if my Supra is a diesal, but that's only because you can hear it over the diesal trucks at my school. =\

Well, I thought I would share the fix to this problem. I pulled the heatshield off my turbo and removed the intake and IC pipe so I could get to all the turbo/manifold bolts. Shaft play was minimal and spun very freely. I got at least a 1/4 turn out of all the turbo nuts, and the most of a 1/2 turn on some. That seemed to do the trick. I never got a sound clip of it, but basically it sounded like a really high pitch whistle. The car never sounded like it had an exhaust leak there, but I guess it did.
