If I remeber correctly, the halting of oval piston development had more to do with the rules banning them from competition that a failure of the technology itself.

Yeah, you're right, bad quality is what Honda is known for . . . NOT!

They already have Hydrogen powered Internal combustion engines in use today. As a result I don't think you will ever see electric GP racing around the track.



Electric powered vehicles and all those Gas Hybrid's are just a stepping stone to the future of Hydrogen powered vehicles.

You could use the article. In the sprit of the late, great Gordon Jennings let me point out: The number of cylinders or bore/ stroke ratio has nothing to do with the shape of the power curve. The only thing that is effected is the maximum RPM the engine can turn, short stroke (from big bore or more cylinders) means the engine can turn more RPM. The Honda S2000 is, by motorcycle standards, very long stroke yet it is peaky and makes around 120 HP/ liter in EPA legal tune. That might not impress you compared to the GSXR1000 (also a long stroke design) at 140 HP/ liter but bikes have a much less restrictive emissions limits and they need to last much longer.



The bottom line is (to steal one of Gordon's great analogies) do you think the gasoline know if it is in a short, wide container (like a can of tuna) or a long, narrow containers (like a can of soup)? All the fuel/ air mixture does is burn, if there is lots of it and/ or it burns more often you get more power, if there is less or it burns less often you get less power.



I very much doubt the folks at MO have the resources to devote to a subject this complex. My favorite technical site, Wheelbase, is off line since Gordon died. Your best bet would be to find a good book (you can always start with by Kevin Cameron's Sportbike Performance Handbook) and read it.

Default Uhhhh...

What would an American agency (the EPA) have to do with a predominantly European and Asian racing series? Last time I checked, there weren't any GP races in the US. The EPA's rules have little or nothing to do with the rule changes.

ok, bud,

i guess your naivety disguises the REAL world quite sublimely.



You are a damn fool to think they would use a production motor. Harley DEFINATELY has the funds to use top engineers from wround the world to build a world class motor.



Yeah, smart guy, lets compare race motors to street motors. Christ

Default Re: Dirty Oil

Yes, but your car has to go 5000 miles between oil changes. I think aerobatic aircraft run without oil filters. I think the engine will run fine for an hour or two without an oil filter. I might be wrong, but I don't think it was that stupid a question.

Solve this probelm by pre-running engine, then drain initial dirty oil. Then change oil after every race.
