LOP is the short answer. TIT in the 1450 range – about 16 – 17 gph. Give up a little HP and speed maybe five knots or so.

Subject: [LML] Why is my fuel burn so high in my IV ????

Reading some of the posts on the LML about IV/IVP drivers. Just wondering how they are getting around 18-19 GPH at cruze power?

I have a straight IV with a TSIO-550-B. I usually fly around 10K feet, using 28in MAP, 2400 RPM, Leaning to 1550 TIT, and getting 21.5 GPH fuel burn.

What am I doing wrong? How is everyone else getting there fuel flow so much lower?

Any advice would be much appreciated.

Thanks,
Guy Foreman
