Hi Bill,
the W/P pulley is about 4 inches dia and the eshaft pulley is about 4.75 inches dia. A 5.5 inch dia W/P pulley would fit with the standard eshaft pulley but if we want to go any bigger, then the eshaft pulley would need to be correspondingly smaller. In the attached photo, do not be fooled by the eshaft pulley on the front, that is for other uses, the W/P driver is behind this and is smaller in dia. It also carries the CAS toothed ring, you can just see a tooth or two in the pic.
I think somewhere in the range, 4 inch driving a 6 inch W/P pulley would give us about 4000 rpm - alternator, at 6000 engine rpm in cruise. Even if we reverse the present pullies,ie 4 inch driving the 4.75 inch W/P,w are in the ballpark.
Are you located near the Racemate shop? I am on the other side of the world, but I could get a W/P cartridge to them if necessary. I have the online catalogue but it does not give pulley size info. BTW, the RX8 cartridge looks to be the same bolt pattern as the earlier models but the pulley do not stick out as far,( the End Hsg is thicker}, and the material in cast Alum. This pic came from Rupert of asianautospares, and is typical of his engines, you can see it is 'as new'.

Dave, I was checking on Racemate when a big job at work intervened. I called them and the said they would be glad to attempt a rotary install. They need the pulley size you want to run and the case/cover you want to attach the stator to. The pulley size of the rotary is a bit small for the racemate, but you could change the e-shaft and WP pulleys and be fine.
