Nice.

Or you can run e85 "race gas", but that defeats the "poor man's race gas" idea behind it.

Since you, MattO and I are in Norcal, we should not have a problem with the summer/winter blend deal E85 users face in other parts of the country. My research before choosing to go E85 on mine showed Norcal pump E85 has been very stable in the 85-90% range year round, at least that was the case when I dug into in this a year or so ago. I have the Quickfuel test tube and will be checking each batch of fuel.
FWIW, some pump E85 I bought in Concord in late 2013 registered 88%... I had some leftover after the dyno and I decided to test it a month or so ago and it registered 84%.
