I have one at 575HP. The big known issue is the fuel injection pump, it comes apart inside and the passes the parts onto the injectors where they get taken out.
When I spoke with CAT about the issue they told me that it happens fairly quickly within the first few hundred hours of use and it starts with a big drop in fuel pressure.
Otherwise they have been reliable.

I talked to the cat dealer yesterday and that's exactly what he told me. Hi pressure fuel pump but other than that nothing
