A friend of mine does/did hold world speed and economy records for his car, really a suitcase sized chassis powered by a model aeroplane engine of below 10cc. He made super low friction wheel bearings and transmission for it and was in the Guinees Book of Records for a few years.
Of course, my Drum Car is the fastest drum kit in the world!
Gwenda Stewar set a LSR in a Morgan 3 wheeler in the 30s, with 116 mph and 1 or 1.1 litres, extremely impressive for the time.
