Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together. There was a lot of trial and error as jury-rigged parts were improvised and revised, leaks were identified and plugged, and byzantine electrical diagrams were decoded. It still does not run smoothly, as there likely is a problem with the intake system that has prevented smooth timing at idle. But she runs!
lots of people wanted to know where the E-shaft came from: it was custom ordered from a shop in New Zealand.
Subaru Impreza 10000 RPM engine
Takhle vypada subaru motor kteremu upadne ventil v 10000 otackach. - This is Subaru engine, broken valve in 10000 RPM. This was not poorly tuned, EGT and AFR was right, Problem was in material of one of the Cosworth valves, there was air bubble in it and it broke apart. This was not one shot as you think, this car was running few months before this and it is running again fine after repair. But we changed manufacturer of vents :-)
