with a twin you can build a scavenging exhaust too

too late, the team is commited to the single cylinder, it was selected last year, this year was futher devleopment. We have 2 dead engines sitting around. One blew the bottom end, the other one lost oil to the heads and the exhaust valve seized and the piston shoved it through the head and bye bye motor number 2.
Max displacement is 610cc. There are talks in the team of using a Honda 450cc 4 cylinder found in the japanese market only. But that is $$$ and parts are scarce. We aren't trying to match 100 hp, maybe get around 60 HP. 60-65 HP would give us the same power to weight ratio as cornell with their yamaha 610cc turbo. |

What would happen if you cryp treated a rotary? I mean everything, housings, rotors, plates, apex seals, e shaft, everything!
Would if affect anything? maybe the seating of the apex seals is all I can imagine. but i dunno, anyone? The apex seals are already heat treated, the cryo won't work on aluminum, and will have no effect on springs. Dave |

Do u have any reference to a ANSI or ATSME paper? because i can't find one.

There aren't any ANSI or ASTME references because cyrotreating is useless. For the amount of money you spend on cryotreating u might as well use better materials with superior properties.
