A mate just finished his RV12 - 912 100HP full Dynon kit. $75k complete. 1000 hours build time. He's getting 115 knots at 5,100 RPM and 125 knots at 5,300rpm and max RPM with his set-up is 5,600. From memory VNE is 135knots. He has done 12.5 hours in the last week and he is absolutely LOVING the aircraft. His other two aircraft have just been mothballed and are unlikely to be flown by him again as he is so happy with this one.
