Don't forget to put the word STEEL in the light carbon housings comment. People might think carbon fiber. The intent is to be able to nitride like the stockers.

Kelly,
As Lynn alluded to, they cut/grind down the 13B rotor housings to the 12A width. Side housings for a 12A can be 13B early Cosmo housings which have the seal groove in them rather than the Rotor housing. You can mix and match most parts if your prepared to modify. Powersport actually used a 12A e-shaft in their very light motor, they just reduced the centre housing thickness.
I'm using a 13B Cosmo rotor housing (big exhaust port) with an RX8 rotor with 3mm apex seals and 13B end housings ( Bill Jepson's light carbon housings- when available).

Lynn,
Does Rob use any special tricks we have not heard about before to make his
12A's live above 10,000 rpm ??...............Also what are you 12A racers doing
for side and rotor housings as some are out of production now ??...........

Dash 12 on the racer, probably not smaller than dash 10 on the airplane.

Mazda RX-7s finished 1st and 3rd in the just completed National Championship race. Winner Rob Warkocki builds his won 12A race engines. I took one of his apart long ago. Built to perform above 10,000 RPM. Very nice.
