Uhhh…that would be a Turbo Charged Lycoming HI0-360-F1AD, thank you. Actually, with the first legs all heat and montains, I’m not too disappointed. I normally fly at about 1550 TIT to bring in 16 GPH but with the altitude and heat (115 F on day 1) I had to run closer to 1420 so as not overheat,19 GPH with a IO360 4 banger? Wow!
