Seems to be a lot more leget than some of the others I have seen out there, mainly because this guy gives actual detals of his setup.

I have seen that link before. But thanks for the reminder! That car's owner established an ecomodder fuel log at one point: 1993 honda del sol s Gas Mileage (dturbosol) - EcoModder.com. And in a couple log entries he reported about 70mpg across full tanks with average speeds of 55mph and 58 mph (during summer). But he did really extensive and complex engine mods, it seems, including designing his own lean burn "prechamber".

Check out his first fuel use gauging method: I did some FE testing 64.8mpg - Page 5 - D-series.org

Here is the fuel map he discusses, in post 50. The highlighted blue is the lean burn zone:

And here's a pic of some aeromods he reports in post #63, reporting over 70mpg:



In post #71 he promotes ecomodder, as he suggests he wants to build a kamm back. In a later post he seeks a CX transmission from a guy.

Here he is designing and prototyping a huge boattail:


Quite an amazing thread. Skills and motivation like few have. Amazing.
