Your climb sounds like you have a climb prop. I have an 85hp 415 C also. I experience about 4-450 fpm climb at about 7-75mph. I figure about 8 gal an hours as a balpark number on it. I find climb fuel burn varries a fair amount with altitude. Above 5000 ft when the carb starts to become overrich the fuel burn on mine starts to go higher with less performance. Just gotta be a pretty good reason for going up there. Like the Mountains when I flew from Michigan to Maine... we went out at 7500 ft. Fuel consumption was aweful! Won't do that again til I get a mixture control put in.

Hello! It is me again.

For the life of me, I can't seem to find a "Time/Fuel and Distance to Climb" chart or info for my 415c with an 85 horse Cont. engine. Was upgraded to that from a 75, with carb throat mod.

Would like to know how much fuel I am burning in a climb at 80 mph. Full fuel at max gross. Also FB at 2300, 2400 and 2550 rpms.

I don't have a vertical speed  inst. but I can stop watch the climb with the Altimeter. I did it with halve fuel and calculated to 500 ft./min roughly. Any suggestions is highly welcomed. Thanks gang,

Ed
