Hey Bryan,
Let's start a new thread. Based on recent banter I think a good title might be:
"The perfect VW (Chasing the Dream)"
What da'ya think.
Anybody with excess of say at least 500 issue free hours in the air please tell us about your findings and solutions!
If you listen to Jeff's pod cast on SDS EFI, "Episode 58 - "SDS EFI for your AeroVee" (ref.
http://www.sonexflight.com/58/sonexflight_e58_jun2019.mp3), Peter claims (if I'm remembering correctly) 600 hour of trouble free flying. However, as a maintenance item, he refreshed his heads every 200 hrs.
However, I did not want to be a naysayer and squash all his ambitions.
Impossible :-)
There is a lot to learn here.
I had never read a study about valve temperature. That pretty much proves that VW flyers don't need to look at CHTs when they find burnt valves. The problem is more likely high valve temperature and the best proxy we have for that is EGT. Maybe VWs just have to be "fuel cooled" under heavy load. That can be best done with balanced fuel distribution and that can be best done with EFI.
Pressure differential between the upper and lower plenum should be about 9 inches of water at full power, which a well designed and implemented "firewall" forward should be able to easily achieve at about 100 MPH.
I'd like to know how to do that!
Like I said, a lot to learn.
Anyway, the perfect VW? Take a RevMaster, replace the ignition with AeroVee ignition, replace the charging system with a Great Plains 35 Amp (Harley) alternator, add EFI, and find some gold paint that will stick :-)
