These upgrades helped to increase the engine's power output and improve its reliability on the track.In terms of performance, the Ulster was one of the fastest cars of its time. It could reach speeds of up to 100 miles per hour, which was very impressive for a car of its size and era. The car's lightweight construction and advanced suspension also made it very nimble and responsive, allowing drivers to push it to the limits on the track.The Ulster was also a successful racing car, with numerous victories and podium finishes in major motorsports events. It won its class at the 1935 Le Mans 24 Hours, and went on to win the RAC Tourist Trophy in 1935, 1936, and 1937.
