It'll burn about 7 gal/hr on takeoff or otherwise wide open, and with reasonable throttle setting and leaning will drop to around 3.5 gal/hr cruise. The efficiency of the plane determines how fast you'll be going in cruise, but 130 mph is a pretty safe bet. Mine will do 160 mph true airspeed burning 3.8 gallons or so, if that's a clue. 10.5 gallons per side is a pretty nice number. I only carry 15.5 gal total, and I can make over 500 miles if I'm not in a big hurry and throttle back a tad. For a lot more info on the performance of a KR running a Corvair (both 2700cc and 3100cc) see http://home.hiwaay.net/~langford/performance/ . That first chart stinks because it was made on first flights where the EIS was all "jiggly", so I need to replace that and generally update that whole page, but there's some pretty solid info on that page...
