Seems to me that intake manifold vacuum is an issue for any engine--carb or FI--in as much as the throttle plate affects losses of power for pumping air. Higher vacuum means great pumping losses, no? Anyway, if you really wanna do such a challenge, take it on ina new thread that will get new attention specifically to these ideas and importantly can also end up a featured thread on the main page. Folks here can help set the parameters of the challenge. This is an important tuner/ecomodder debate and so a really great testing/building thread on it would a very cool contribution.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
