John – I typically climb at around 800-1,000 FPM and 120mph on a summer day in Michigan. I plan on burning 22-24gph during my climb. I use N430DP for mostly cross-country flights. When in a cruise around the 7,500-10,500 altitude range I usually average and plan for 200mph with a fuel burn of 14-15gph. The plane has the IO525 engine with Gami injectors. There have been many occasions at altitude where I am cruising well over 200mph depending on conditions. Hope that helps! Feel free to call anytime 419.704.1981.
