" I fly with two mags."
Ah David,
Remember, you do not always fly with two mags ,like the time you had to divert to Flinders Island after an in-flight mag failure WHILE crossing BASS STRAIT
( a potential bad day handled well, good job !! )
David has turbo normalised injectors on his RV-10 that gives him repeatably the best gami spread I have seen.
I have not been able to get my gami spread repeatably as good and suspect an intake gasket failure on No 1.
(Ross,I'll talk with you soon about your new intake clamps
)
You can see the effect here where I am effectively flying with a five cylinder engine while LOP at 29 degrees advance. ( 37LPH = 9.7GPH )
Michael, David and I will probably have a head to head comparison after I sort out my gami spread/induction leak issue some time in the future.
It should also be noted that I also have an exposed A/C Condenser pod mounted on the belly of my aircraft and what difference that makes,I am not sure,but the data point should be recognised that there are very few identical RV-10's to compare with.
It should also be noted how many rotating mechanical parts it takes to keep the old mags running. When I removed my last mag,I was surprised to find the bearing spinning on my mag drive unit verse the ZERO moving parts on the Dual SDS CPI system.

I won't be going back to the "good old mags" anytime soon
