If 0-200's running flat out at 3100 rpm and 3100 cc Corvairs running flat out can't get the KR to fly at the 200mph Vne speed, I can't imagine the J3300 will be capable of getting the KR to "dramatically exceed" the Vne of the KR in level flight, even with the new faster wing. The lighter weight and additional hp of the J3300 should improve the takeoff performance on any kind of runway surface. Landing distance can be controlled with the use of flaps or speed brakes. I can land my "heavy" KR in 1500 feet on a hard surface with the use of a speed brake and airspeed control. I've never heard of any control surface attachment or engine mount problems on a KR other than in a crash and consider both to be quite adequate to the 200 mph Vne speed. I seem to recall Richard Shirley is running a J3300 in his KR1 without any problems. Just my opinion and not very scientific. Go with whatever you are comfortable with. Larry Flesner
