I am interested in doing this too. I wonder if I should go F1 or if the D1 would be sufficient.

Those who are running the F1 (or a high boost D1) with built blocks, what is your CR? And do you always run higher octane, or do you run straight pump gas? I would not want to have to mix gas every time I fill up, but don't know if I can run a blower like the F1 without doing that.
