as the RPM's were being discussed here, and I had very little to do at work this morning I figured I do some searching:
this is what I came up with:
Did you know: (Did my best translating from a Dutch site)
the use of non synthetic oil can result in turbo damage, especially if not changed often enough.
Mixing non synthetic and synthetic oil is not always a good option, as its possible they do not properly mix
if the engine is filled with synthetic oil, and topped up with non synthetic, the synthetic oil can can lose up to 50% of its effect
when oil pressure is low in engine the turbo is the first part to suffer
Sumppressure or blocked oil breather pipes will cause the turbo to leak
The turbo turbine of 20.000 rpm accelerates over 150.000 rpm within 1 second
The maximum a turbo axle may be unbalanced equals a force of 2KG, which is often exceeded to 6KG before people get their turbo looked at/repaired
The air sucked in by the turbo travels at a speed approaching Mach 1
New generation turbo's can reach RPM's up to 220,000 rotations a minute, apposed to the propelor of a Boeiing 747 'only' spinning at 7,000 rotations a minute
Average exhaust temperature in the turbo for a diesel lies at 800 degrees celcius and for a gasoline 1000; hot enough to melt glass
Many people, wrongfully, assume that the dirt present in the engine is filtered out by the oilfilter, before it can do damage to engine parts/turbo (Glad I installed my catch tank lol)
A turbo spinning without oil for 4 seconds already causes damage to the bearings.
A turbo spinning 8 seconds without oil, is permanently damaged.
A turbo spinning without oil for 4 seconds is comparable to an engine running without oil for 4 minutes
