I am coming up on 500hrs on my purchased flying RV7A. Dual Slick Mags. Running just fine. I read where I should have the Mags inspected to the tune of $500+ each. Reading about the fuel savings, non hot start issues, and inexpensive spark plugs have me thinking. The hesitations I am having is the rise in CHT and 100 hour inspections. (the P model E-Mag is what I have been considering). On really hot summer days, I can creep up over 400 degrees in a climb to a higher altitude if I want to do it in short order. I want my motor to last long beyond the 2000 TBO. I am only 4 years into aircraft ownership and maintenance and I have to admit my ignorance and inexperience with how the temps truly effect the motor. I have seen some folks say they see 20 degrees higher CHT with EI. Is this worth worrying about? Is that rise at a given fuel flow and making more power with the EI and just reducing the fuel flow would render the same CHT and power that the mag was producing with using less fuel? Can someone speak to the number of trouble free hours they have had out of P-model Emags? How long does your 100 hour inspection take?
