Eustachio, I'm replying to my own reply because the link for Deakin's article does not seem to work. Here's how to access it: go to
www.avweb.com - then in the "search" blank enter "pelican's perch" and hit enter - then download items 3 and 5 by Deakin about engine power. The one refered to above is number 5 and I have yet to read number 3 but 5 relates to takeoff power.
I just re-read 5 and it is an excellent article and well worth reading. Deakin is a proponent of LOP operation with GAMI injectors - which is controversial - but this articles gives one the option of either ROP or LOP. Lots of really good information here!
