I ran into a coil power issue a couple of years ago with methanol and high boost , and needing to go dangerously lean to fire it , actually ended up too lean and melted several heads, and now wanting to go back down the methanol path, but better informed and with as much ign power as i can get .
I ended up buying the "dumb" coils , will see how they perform
I wish e85 was more in use here, i think it would be a great option,
