I once had a chance to drive a full size Volvo tour bus in the UK. The most memorable bits of my experience? First, I managed to drive the bus through streets no wider than a driveway without hitting anything or killing anyone. Second, redline on the diesel motor was 2,500 RPM.
I’m a bike guy and a sports car guy; motors, in my experience, don’t even come on cam until three grand and higher. The concept of shifting at 1,000 RPM just blows my mind.
In any case, here’s what happens when you put a diesel motor on a dyno and over-rev the crap out of it. Things go from bad to worse very quickly, and I’m glad to be watching this from a safe distance. Connecting rods, fired from an exploding engine, definitely leave a mark if they hit you.
