Last weekend, another brilliant Goodwood Revival. And in what has become a pattern of the last few years, I happened upon some technical marvels from the past.

Peugeot radial 150920Like the 1930s Peugeot motorcycle with the (modern model)Radial cyclinder 150920 radial engine, 100cc and 9 cylinders, each with its tiny separate exhaust.

Hilborn 150920And the Hilborn mechanical fuel injection on the Sadler Chev from 1957. Fuel pump driven from engine speed so you get the variation in fuel pressure that you need – and you use the size of the orifice in the return pipe to the fuel tank to manage your metering. Very neat. But best left for race applications where most of the time you’ll be at wide throttle openings!

.

Lycoming 150920The Lycoming aero-engined race car from the mid-50s? Now there’s a unique car, with more information at: http://classicdriver.co.nz/the-lycoming/ explaining that there was more innovation than just the engine.

So, another weekend not only of wonderful racing, but also of innovation in action.
