Porsche model engine (scale 1:3) working demonstration 

This afternoon I've witnessed something very very special.
A Dutch Porsche driver, and precision instrument maker, has build (more than 40 years ago) a Porsche 911 engine, scale 1:3.
Not as a static, but as a WORKING model. He has build everything by hand, working from the original factory drawings.
Some of my Porsche friends got aquainted with the man and finally he was willing to give a rare demonstration this engine.
It was awesome, the noise, the revving . . . absolutely fantastic !!
