British Anzani A & B Stock & Alky Racing Engines

[John (Taylor) Gabrowski]

The following picture is a late Model British Anzani with late model expansion chamber racing exhausts. The engine just can't get away from the classic crescent shaped exhausts systems even with expansion chambers. The shape remains. Anzanis so equipped also had a departure from the fuel they used which meant when you went with the supercharging aspects of modern expansion chambered exhausts you also dispensed with using nitromethane in the methanol fuels anymore. It was just too much power the earlier versions of the crankshaft to take.
