For those who follow this thread I have some great news for you. Last October 5th, 2008 I set what I consider to be the highest mpg ever recorded for an A -series Datsun engine at the A.M.E.C. Economy Run II event. That number was 61.5 mpg [US gallons].

With all of the further modifications you've read about in this thread, I competed in this past Sunday's A.M.E.C. Economy Run III event. I completed the 104 mile course through the hilly southern Adirondack mountains and the post event refill showed that my fuel consumption was 1.35 US gallons of gasoline.

This equates to a new record of 77.04 mpg . [We hit our goal of 70 and then some David! ]




Here are all of the event results:

Note: I could have easily won the Historic class ['79 and older] but I chose to run with the heavy hitters in the Gas class and go head to head with much newer and highly modified gas cars. This was a little silly to try as the Hondas have factory fuel injection, electronic lean burn systems, vte-c, etc. But as far as carbureted cars go, I had them covered.
