I propose a motorcycle racing series where the only limitation on the engine is that it must displace 50 cubic centimeters or less.
This is mostly because I would like to see the limit of what is possible with only 50cc's. I imagine that an engine with modern technology like electronic fuel injection
and forced-induction could make up to 60 horsepower on racing fuels like nitromethane.
Besides being an interesting engineering exercise that would leave plenty of room for innovation, it would be rather inexpensive, allowing amateur teams to get involved.

Apparently, this kid of thing happened from 1962 to 1982 [rasberry re-tart, Sep 29 2007]

this is where I got my estimates for 50 to 60 hp out of a 50cc, since 8193.5 cc engines make about 8,000 hp, and electronic engine management and turbochargers could add even more [rasberry re-tart, Sep 29 2007]

My electric motorcycle will crush the competition, and have room to carry 50 CC's of hot espresso. |

Although you just have to love a 50cc 17,000 rpm 10 HP racing bike, "50cc Unlimited" is an oxymoron. |
|
| |
Racing fuels like nitroglycerine would get a bun from me.
Maybe you should have called it "50cc, Unlimited Racing Series." To keep the hobo happy! |
|
| |
While nitroglycerin would be worthy of the 'bakery, I doubt you could get many race drivers to get on that bike. |
|
| |
Check out the second link for a description of nitromethane fuel. |

Well yes, but when getting air in to burn the juice is the problem, explosives are the solution. Of course if using nitroglycerine you might have to packet the injection, and keep everything else damped, and do NOT crash, but otherwise I think the bakery is the ideal place for it! (link) |
|

Explosive fuels mean short engine life. Grand Prix style races are out, leaving 50cc drag racing the venue of choice. |
|

Are you allowed energy storage systems? Just run your 50cc engine for a couple of weeks (constantly) prior to race start, storing energy in batteries or compressed air or similar. Output hundreds of horsepower throughout the duration of the race (assuming that it's a shortish race). |

50cc of plutonium. I win. Granted, I might have to mount it within a U-235 rear wheel to achieve critical mass, but I don't see anything that forbids it... |
|
| |
50cc starter motor on a jet turbine. Meet you in the winner's circle, if you ever get there. |
|
| |
1cc of antimatter, 49cc of water. I win. Someone please help hose me off the grandstand? |
|
| |
How about a 50KJ race, where you are only allowed to use that amount of energy. |
|
| |
Would it be practical to design an engine which injected two liquid fuels that would vaporize and combine in the piston? What would the safety implications of that be if the fuels were stored in tanks that were kept well separated from each other? |
|
| |
Or have a Cesium piston head and just spray a tiny bit of water into the cylinder. |
|
| |
I'd rather see a limit on the fuel than the displacement. Give everyone a specific amount of gasoline and let then do whatever they want. Then you'd actually get to see turbines, wankels and fuel efficiency turned fun. Don't go crazy on the minimum MPG. If you just limit displacement, the winner is the one with the best turbo/supercharger/intercooler combo feeding a nitromethane burning wankel. |
