Which turbo is healthier (pics)?
I took a picture of my turbocharger in May 2005 when I was working on the exhaust. Then, I took a pic today when I was working on it again.
Back in 2005, the vanes were covered in a white powdery substance. Today, there was much less... even a blackened center. Which is better? Is my car now running too rich? I haven't done any mods to the car. Thanks in advance, - Mike May 2005:  September 2008:

I think mine is running rich... explaining the carbon deposits on the blades.

You know, the more I think about it... the first pic was after the OEM exhaust and CAT were removed to bolt on the new Fabspeed (sans CAT). The car was always running (oil temps) about 210 F. with the OEM exhaust.
The second pic was after two years with the aftermarket exhaust, no CAT, and normal oil operating temps of about 180 F. It is also tuned a bit richer. So, the turbo in the first pic was exposed to higher heat, and a leaner burn. The second turbo ran a bit cooler, I would assume. - Mike
