Coming back from the Race to Ridgeland in South Carolina yesterday, my -10 suddenly showed highly elevated EGT's for no apparent reason. I had been running 23"/2350 RPM and ROP, around 1330 EGT and all of them suddenly went to 1410/1430 without me touching anything. I had been running 15.4 GPH, so I enriched the mixture to lower the EGT's to near 17 GPH.
They did come down a little, to just under 1400 degrees with fuel flow at 17 GPH. The CHT's had not risen at all during this episode, so I suspected a Dynon problem. (D-120 EMS).
I also considered the fact that I may have developed a fuel leak under the hood, so I braced myself for a possible in-flight fire and was ready to shut the fuel off. If the engine was truly starving at 17 GPH, all of the fuel must not be reaching the injectors, hence the high EGT's, no?
I remembered Todd Swezey's cockpit fire and explosion at Ridgeland a few years ago, so I decided to NOT touch the flap switch in case there was fuel in the tunnel, and landed fast and long at home.
I will de-cowl the airplane and I'll report back.
Opinions anyone?
Best,
