John Pleisse Posted January 24, 2014 Report Share Posted January 24, 2014 About 16.8 gph on climb, Bob...and about 11.8 to 12.1 just tooling around at 3,000 ROP. 1 Quote Link to comment Share on other sites More sharing options...
John Pleisse Posted January 24, 2014 Report Share Posted January 24, 2014 When I did my break-in some years back, I kept MP/RPM above 24 squared, as full power as I could achieve, varying the RPM within this range to avoid developing any harmonic. I kept a strict diary of RPM-MP-MSL/Pressure-and time. It was broken in by 25 hours, but I kept at it until 50 hours and then put new oil in. 2 Quote Link to comment Share on other sites More sharing options...
N601RX Posted January 24, 2014 Report Share Posted January 24, 2014 I see around 18.5 on takeoff at about 200' above sea level. 1 Quote Link to comment Share on other sites More sharing options...
Bob_Belville Posted January 24, 2014 Author Report Share Posted January 24, 2014 I have a JPI 930 so I have a good log of flight data. I also have a direct read out of percent horsepower at all times so I will be able to run at 75 percent and vary r. p.m. As as needed during break in.

Bob_Belville Posted January 24, 2014 Author Report Share Posted January 24, 2014 Yes. And that's why I was asking about the 18 gallons per hour. My more recent flights were lower than my earlier flights and I'm concerned about the adjustment. Sent from my XT1060 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Bob_Belville Posted January 24, 2014 Author Report Share Posted January 24, 2014 Plus I would love to have better cooling in warm weather climb out. Sent from my XT1060 using Tapatalk Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 24, 2014 Report Share Posted January 24, 2014 Isn't there an official document that states FF for the engine? TCDS maybe? For the IO550 it is about 2X the normal cruise FF at LOP. Hope that helps..., -a- Quote Link to comment Share on other sites More sharing options...
Hank Posted January 24, 2014 Report Share Posted January 24, 2014 Look in the Performance chart for sea level, 2700; for my 180-hp C, that's 18.2 gph. Quote Link to comment Share on other sites More sharing options...
KSMooniac Posted January 24, 2014 Report Share Posted January 24, 2014 You should be in the 18-18.5 range, especially with cool temps in January! If you're getting less than that something isn't correct. Quote Link to comment Share on other sites More sharing options...

Hum, my old Owners Manual has "cruise and range data" charts but they start @ 2500'. @ that altitude 2700RPM & 27.5" MAP which is labeled 97% BHP, fuel flow is 13.8. (The chart is for Best Power Mixture so it may not be full rich. Quote Link to comment Share on other sites More sharing options...
jetdriven Posted January 24, 2014 Report Share Posted January 24, 2014 The Bendix RSA has no fuel flow adjustment. It it's outside what's normal then check for induction leaks or the FI itself for defects. Quote Link to comment Share on other sites More sharing options...

My C book is there, too, from 1970. Good luck, and welcome back to flying again!! Quote Link to comment Share on other sites More sharing options...

It it's outside what's normal then check for induction leaks or the FI itself for defects. An easy way to check for induction leaks is to tape over the air filter, and use the fitting from a compression test set to pressurize a cylinder of your choosing...just rotate the prop until that cylinder's intake valve is open, and then apply pressure. Spray soapy water solution on every joint and look for bubbles... 1 Quote Link to comment Share on other sites More sharing options...

Bob_Belville Posted January 24, 2014 Author Report Share Posted January 24, 2014 They were just checking for leaks but I hope they did not run long w/o cowl! My A&P doesn't like to run an engine even with just the top half off. Uneven cooling, unfiltered air. Quote Link to comment Share on other sites More sharing options...
KSMooniac Posted January 24, 2014 Report Share Posted January 24, 2014 What's up with that exhaust pipe? Is that a powerflow? Looks crazier than the rubber prop! Quote Link to comment Share on other sites More sharing options...

(In fact when I started flying First Class on American Airlines was about $25 extra. Loved to sip Drambuie or Espresso in the lounge on an Electra almost 50 years ago.

aaronk25 Posted January 25, 2014 Report Share Posted January 25, 2014 Bob -- I usually see 17.6 to 17.8 GPH at 400' above sea level. He is Exactly right......same for mine....remember each fuel flow transducer will very a little. Quote Link to comment Share on other sites More sharing options...

The clamp/hanger that holds the tail pipe in trail was not installed. They need a fresh slab of rubber. Quote Link to comment Share on other sites More sharing options...
