IO 360 M1B FF at T/O full power

[Airhead]

I am trying to find what is the anticipated fuel flow (or range) for an IO 360 M1B (Van's) with C/S hartzell and Precision FI. Full throttle / full rich during take off and initial climb near sea level. I have done a search, and although this bush has been beaten around several times, since I am trying to solve an unusual problem, I need info only pertaining to this engine/prop setup, of which there should be many I suspect.
No response from Lycoming and this bit of information is not in the Manual. Waiting for response from Van's. Response from Precision Airmotive was quick and informative, but they do not know the fuel flow intended by the engine manufacturer since different installations may not achieve different fuel flows.

I will post any data I recieve to assist others.

Thanks

You should usually see .9-1.0 gph per 10 hp. I know this is not specific to your engine, but with no other replies, I figured I would at least give you some answer.

With this engine & prop combo I run about 16gph at sea level 2700rpm full throttle FWIW.

Hum...I've heard one Lb. Per HP per Hr? Not sure........

That would mean a 180hp engine would be burning 30 gph at takeoff. Our RV-10 with 250hp burns 23-25 gph at takeoff at sea level.. Another -10 I flew today was reading 22.5. The other comment of 16gph, I assume with a 180hp engine.

Taking off, I'm burning between 15 and 16 gph. As soon as I'm at altitude, I slow it down a bit and settle to about 7.2 to 8 gph cruise.

The data sheets with my (180hp) IO360 M1B engine shows 87 pounds per hour or 14.7 GPH at WOT 2700RPM and best power A/F.

The sheet for the 200 hp shows 93PPH or 15.5 GPH.

A little variation or additional richness (is that a real word) then You have an operational range.

This makes BSFC .465 to .485 #/hp-hr.

Your data may vary. (YDMV)

From my datalogs, I typically get 17.2-17.7 gph on take-off. Superior 180HP IO-360 with P/A injection, Hartzell blended airfoil prop. My prop overspeeds a bit on take-off, something I need to deal with. Typically I'm at 2730 rpm on the roll.

I get about 15-16 gph at the full power with the same engine/prop. Hope this helps

G'day,

Same engine, injection, & prop, RV-7: 61.5 litres per hour (16.2 USG/Hr) PA 70ft AMSL, DA 2000ft.
