Dan:
This is topic for a new thread because it’s unrelated to F500 Carbs!
Years of endlessly discussing this topic online is pointless and it has solved nothing in the past!
Per the current F500 rules the Rotax Model 593 Engine has mandatory 25mm restrictors in an 850lbs. car and the 600cc Motorcycle Engine now has a mandatory 28mm restrictors in a 900lbs. car. There is no 114hp or 115hp standard or target in the F500 class that I’m aware of. In fact, show me any SCCA CRB/BoD approved document that defines any engine horsepower standard or target for any engine in the F500 class. IT DOESN’T EXIST to the best of my knowledge!
The only way you can change the rules is to write letters to the CRB! Endless talking for years and years is a complete waste of time and accomplishes nothing IMO!
Thanks, I appreciate your support for the 494/493 Engines!
