A/R ratio-stamped on TA49=.60

[bogie1]

I just got my new TA49 Turbo. It is stamped on the compressor Garret .60. Is the the aspect ratio of the turbo? I am confused. I have only seen .63 or .82 for a TA49. How can It Tell what A/R it is?
Thanks,
Rich

Your looking at the compressor housing size.

The other numbers you mentioned are reffering to the exhaust housing size. Most GN owners change the exhaust housing to fit their performance needs and talk about those numbers way more often.

Most likely you have a .60/.63, very common set up.
