With the engine at operating temperature it was very easy to block the fan with a thin unfolded news paper. After switching off the engine the fan could be made to turn over 10 times by giving it a good swing.
When you are visiting Munich, it’s highly recommended to pay a visit to the local BMW museum.
What can you expect? Well, don’t expect a very large museum. On a spiral ramp you walk from the bottom floor to the upper floor, seeing a couple of plane engines, some vintage cars, some information on monitors..etc. Nice to know: the M30 engine is also used as an marine engine with a heck drive.
