...sorry, rockers+shaft, valves+springs and retainers were taken from my page on GC: https://grabcad.com/h.segeth-1/models
P.S. The intention of recreating all the moving/rotating parts of the engine in CAD was to determine the mass moment of inertia as I came by a power measuring device of Schrick (LM-1) which needs the mass moment of intertia as an input to calculate the power over RPM

Re: Mini Technical Drawings / Posters
Interesting you have a Schrick LM1 - we too used to have one in the early 90ies at HIOB-Motorsport (infamous but top-notch BMW-tuner in Austria). Haven't heard of such a Schrick dyno ever since...r.tec wrote: ↑Mon Oct 31, 2022 7:47 am ...sorry, rockers+shaft, valves+springs and retainers were taken from my page on GC: https://grabcad.com/h.segeth-1/models

Yes I am a nerd: I am researching the Austrian Mini-racing scene of the 60s and 70s

A bit off-topic, apoligies...
Yes, the Schrick LM1 takes the same principle as the Swiss Syntec TB109 (https://www.syntec.ch/english/petrol-in-blood/) but in a much smaller physical size, more or less a bit bigger than a pocket calculator. It is not on sale any more but every now and then one of them pops up in one of these sales websites. It is much easier on the engine than a rolling road and measures the power "at the flywheel". I normally set it up to measure between 2500 and 6500 RPM.
