The sound that engine makes coming out of the paddock is great. Wonder if it can be made to pass emission standards or if it will be a track-only bike. |

Now that bike has changed some standards - 300lbs, 200hp, 100 ft/lbs of torque at only 700cc - that definitely makes it a game changer - wonder if it will be buried or produced - still it is awesome to somebody step forward and make something we have been asking for tons of power and torque in an ultra light chassis to make handling the bike easy - not a wrestling match only fit for pro racers as most superbikes are. I bet it gets buried by some company with lots of money, so it never sees production. Still that is an awesome bike! EZ |

Wankels have a very hard time meeting emissions standards. The combustion chamber moves along and "smears" the fire. Also, I guess they have to burn a little oil to keep the apex seals alive. When the RX8 came out I was drooling. I loved the sneaky rear doors and the sound of the engine. Now that they have been out for a while, they have proven themselves to be a bit sucky. I don't care. I still want one! LOL |

Wonder if it can be made to pass emission standards or if it will be a track-only bike. Why not? The RX8 passes, and Mazda is already working on the next generation wankel RX8. Might add weight, but at 300lbs, 200hp, 100 ft/lbs of torque at only 700cc they could (if they could figure out where) add another hundred pounds! It'd be a handful, but with todays electronics, who knows how much they're holding that bike back. Think 700cc 2stroke. Wicked! |

I'd think fuel consumption would be more of an issue than emissions? |

"pressurized gas cooling system," Possibly turbocharged or supercharged. Put a turbo on a 600cc Moto2 machine and there you go, no? |

What a great idea. Active cooling, presumably taking advantage of phase change like refrigeration. This as opposed to current liquid cooling which is passive, and for which a phase change means near instant death of the motor. By active, I mean using energy to liquefy the coolant between exposures to the engine heat. It would be easy to monitor cooling system status with a pressure gauge. |

No expert here, but wouldn't that require a good deal of power to run the compressor? We're talking a lot more cooling requirement than just running the AC in your car. |

And you still have to shed the heat that's contained in the refrigeration liquid once it gets compressed. All engines are ultimately air cooled. I'm interested to see how they've accomplished this, because they obviously have. |

You guys are so quick to get excited. It's thus far an unproven race bike. The frame and swingarm look like they were lifted off an early 90's streetbike. Not feelin' it. |

200 hp from 700 cc's? That light bulb is shining very brightly! And will live a short and noisy life. Norton has made Rotor engines for years, and made a nice little airplane engine. I think they are out of production. http://www.nortonrotary.org.uk/Brochures/Aircraft. htm wouldn't mind one of these for an ultralight. http://en.wikipedia.org/wiki/MidWest_AE_series Love them Wankels. A RX-7 is on my get one list... when I win the lotto. |

Wankel engines run very hot, so Garside gave this air-cooled motor additional cooling air that was filtered and drawn through the rotors and then through a large plenum before entering the combustion chambers via the carburetors The above is an early version with near total loss lubrication. I'm interested in the "pressurized" system on that race bike... |

All the wankels I've had experience with were gas hogs. I wonder what kind of fuel mileage it gets? |

Wankels rock! But like 2 strokes, burn brighter, make more heat and noise. Power comes from turning gasoline into expanding gas. Efficiency, alas is not the wankel's strong point. Small size for power, great! Resistance to catastrophic failure, Very good! The airplane guys have had great luck with Mazda engines trashing themselves but still holding together and putting out enough power to get down safely. But like any IC engine if you make it burn brighter it burns out faster. Again the airplane guys have found it fairly easy to crank out the power. Tuned intake & exhaust are needed. Add a turbo and you can boost them to awesome levels. And when you burn them brightly they die. But what a glorious sight It can be. 200hp on 700cc's is bright indeed. |
