Just out of curiousity, how were the pushrod gas class minimums determined? Specifically 2000cc MPS-PG (210) and APS-PG (220)?
The power it takes to go these speeds with available fairings and the power capability of current pushrod motors on gasoline vs. their displacement are both well understood entities. Did they get considered when determining these numbers? It sure doesn't appear so. It really appears to be a guess, and a bad one at that.
I'd like to suggest a process. Pick a hp/speed relationship for a really good fairing. I'm sure somebody will ante up the data, I will for the Buell RR fairing if you want. Pick a hp per ci relationship that represents where the really good builders are. Again, I'd be more than happy to help. Do some quick calculations and you'll have your speed capability. Someone will need to have their sh*t together, motor and fairing wise, to get there. Isn't that what the minimum should be?
My calculator says 210 and 220 are out there. Question: how many over 200 passes on a pushrod gasoline normally aspirated motor of any size have ever been made? I mean, on a sit-on bike?
I thought we had this discussion and resolved it last year, no? Why the change?
The fuel and boosted numbers are big, too, but it's a whole lot harder to argue those, since a person can always put more to it, and the constraint tends to be the durability.
