Tim: Oil returned or lost?
Tim:
Installing and using a lower pressure pulse fuel pump to put light oil into the valve train was a novel idea. Was the oil lost or recirculated back to a tank like a little dry sump system? Looking at the octane and compression the ignition timing must have been kept conservative anyway? When it came to pipes I take it having valves dispensed with anything longer than the short zoomies it had? Must have still crackled like some small psuedo Indy car engine! :)
I get the feeling that you always liked exotics?
Tim:
It sounds like a lot of timing but then Merc 55Hs used around 40 degrees with lower octane gasolines it was based on. On the oiling side and head hot spots would more water flow and a larger oil resevoir with a small oil cooler helped with the hot spotting and warpage or was it all at some limits nothing could realistically help? It is some wild innovative engine! It got me looking at YouTube at some old USA and Italian speed record engines, they were also pretty wild in their times.
From what I gather you always had a spark for the exotics, the ones you could build. You had the vision and have the ability to fabricate what may or may not be available or for the fun and adventure you would have done it for yourself anyway. Being able to do it within class rules came to be the challenge and your projects sure do mirror the interesting and theoretical made real. You sure do instill some interest that is spreading, me thinks. :)
