quiet turbo?

[Chakir]

My 2002 turbo isn't audible until I'm over 2000 rpm and even then it's very quiet. Is that normal for them or is mine slacking off? I test drove a 99 a couple years ago and there was no mistaking it, but the engine noise was also considerably louder in the cab.

I have been having that problem to. I noticed an oil leak coming from the top rear of the motor and dripping down both sides to the oil pan. My turbo isn't noticeable until 2000 rpms,but I am also idleing rough and burning much more fuel than usual. I have Banks ram air intake and banks ram air intake manifold and straight pipe. No smoke,loss of power during acceleration but when I hit highway speed it runs fine. Oil pressure and engine temps are fine though. It's a 2004 6.0 with just over 113k.

An intake and free-flowing exhaust will really wake that turbo up if you haven't already done those. Hell when my '96 was stock, I couldn't hear the turbo at all unless I was in the pedal and past like 2200 RPM lol. Now with the intake, 3" downpipe and straight exhaust I can hear it about a second after I hit the go pedal.

I just realized this is a 7.3 forum. My apologies.

The 99 you test drove has the loud wheel installed from the factory (Wicked Wheel etc) 99.5 to 03 had an updated compressor wheel that made them quieter and also created the compressor surge. If you want the sound of the 99 install a Wicked wheel and do a good cold air intake. You'll hear it then, I love the way mine sounds with the X Wheel. Shop around for the best price on those wheels, they all have different names but are exactly the same. Hope that helps you.

Tymar intake will help and as said exhaust and a WW..we have them..

I wish my turbo was quite! Mines on its way out and its rediculously loud in the cab. I also removed the foil from my intercooler tubes last spring and want to go back haha

I have the s&b intake and mbrp turbo back exhaust with a muffler on my 02 excursion.The whistle from turbo out the pipe was great.I now have a 38r turbo on and don't hear it out of the pipe but always hear it now in the cab.
