This Miller 2-cylinder DOHC race engine was designed and built by Ed Miller, of Wyoming, in the early 2000s. Ed’s second engine is an inline twin DOHC with 1″ bore, 1.25″ stroke, and burns methanol (via his custom carburetors) on spark ignition. No oil is added to the fuel as lubrication is accomplished by a pressurized dry-sump system. The crankshaft driven water pump and oil pumps are mounted in the rear of the engine with the water and oil reservoirs contained within the running stand. The stand also supports the fuel tank and fuel pump, starter motor, electronic ignition, switches, water-temperature, oil pressure and RPM gauges. The engine is alternate firing with a double throw crank and is completely machined from aluminum and steel bar stock.
