My original claim on the the first post here seem to be bearing fruit: Gains from alternator deletion are much greater if voltage is kept above 14.5

Two tanks now under my belt with a big improvement in both most of this difference, I believe, is mostly due to the voltage increase. I did fix an intermittently dragging disk brake so I'm taking this with a grain of salt. On the other hand, I have removed the air dam and grille block I had set up.

Last three tanks averaged 24.15mpg
Previous 5 similar tanks averaged 21.7mpg
a difference of 2.45 mpg. A good 11% gain.

This is all alternator free by the way. This is on top of the gain from the original alternator delete.

I'm still looking for someone with a more consistent commute to bear this out.
