I'll try to get you a picture or two this weekend. I have a very consistent 174 True KNTS at 7500 MSL with 2350 RPM and 14.0 GPH my max CHT is 395 and Max EGT is 1300. If I push the RPM up to 2500 I will show 180KNTS True and increase my fuel burn to 16.0 GPH. I did not match my injectors as in a GAMI injector type of system but I did put a great deal of effort into adding baffling into my plenums to give me a good, close CHT spread. The spread is about 8 to 10 degrees F from hot to cold on the CHT's. In cruise I will see 395 F on #5 as the hottest with the coldest being 387 F. the spread on the EGT's is about 60 F with the hottest being 1300 F. I could save 1 gph by letting the CHT's rise 10 F but I try to keep everything under 400F.

Chis,
*I'd* really like a picture or two, if you could post something to the Reflector web area I'd really appreciate it. By the way, what kind of cruise fuel burn do you typically get with that set up? Did you have your injectors flow matched?

Brian,
I have a Lyc IO540 with dual Light Speed Ignitions made by Klaus Savier. I think your question is based upon mounting the ignition coils on top of the engine cases in the location normally used for the fuel spider. My solution was to leave the fuel spider in it's normal location and move the coils outside of the engine shroud. I mounted the coils on the engine frame. I can send you a picture if you need it. This keeps the coils cooler and leaves the fuel lines and spider in their normal location.

Has anyone with a Lycoming and dual Light speed ignition found a good way of mounting the injection spider? bg
