Even an old 17.5 motor will make a F1 car zip. The racing becomes very obvious - who can use the power best and not overshoot!
It seems most clubs took the conservative approach of using 25.5/21.5 with rubber tires and,,,for a while F1 was back. Yet now many F1 clubs have faded away.
F1 was foam tires for years. Rubber tire seemed to help grow the class. I know a lot of people were turned off by the truing and other hassles of foam.
It went to 25.5 from 21.5 because even 21.5 was getting too fast for good racing. I was pretty ambivalent about changing motors, but when the switch was made, mains got way cleaner, even at large events. It worked.
With the current stuff, 17.5 and foams will be missiles. I tried to run a HPI Super F1 on 10.5 (old silver Novak motor) probably 12 years ago. It was ridiculous, even being 200 mm and on pan car width foam.
