Not sure if you’re saying it ran at 2550-2650 rpm or 2925 rpm. However, IF you ran 2925 RPM….
No offense, but that is 60 hours of runtime, on a power unit designed to run 10-15 THOUSAND hours. We could probably run these engines 60 hours without oil and they would still run great. I have read of the CAT 3116 putting out 1000 HP....However with, a MTBF (Mean Time Between Failier) at around 100 hours.
A top fuel dragster puts out between ~ 5000-8000 HP. BUT only has to do it for ~600 Revolutions. (8000 rpm/60 * 4.5 sec per run=600, or close enough)
Shoot…… I could probably get that out of the old lady.....ONCE. (i would be dead, of course.)
Just my 2 cents, but at the cost of a rebuild; my time, at this point of my life, isn’t worth the $. But if I/WE were to have 6 months to live. By all means, LET ER’ RIP.
Just trying to say, 2650 RPM, as CAT designed, is probably a prudent, long life, kind of RPM, to expect from the 3116.
IF you ran @ 2550-2650 RPM I would expect/demand that your rig would run for 12 hours a day for 833 days straight MINIMUM. (Factory rated 10-15k hours)
