There were about 17 cars dynotested if my memory is good.
Here there is the top 3.
The trophys gone to the guys that had the more hp by cubic capacity
The first was a 1915 with 48' and 155 hp, but the engine break down on the dyno.
The second was a 1835 also with 48' and 135 hp.
The third was a 2000 cc with 140 hp.
