Turbo compressor nut torque spec?

[Michael Gough]

Hey guys,
I remembered in the archives someone that had the wrong torque spec for the
nut that holds the compressor wheel to the shaft, and they broke the
shaft....

Turbo city apparently told them 15ft/lbs, another place told them 105in/lbs.
Turbo city told me 15-16in/lbs, which seems quite low. It's assembled right
now. I used 15in/lbs. I'm wondering if anyone else has ever had one of these
apart and can tell me what they torque it to?
Thanks a bunch
Mike
