Race-gas
I ran the AV gas for a few years and still use it occasionally as there is a small airport 5 blocks from my house. Roosterville Airport.
Works great as you say and I have no problems using it. I mix it about 50/50 with 93 octane BP and I have never had an issue.
The purpose and reason to use the Race Gas is to be portable so you can go anywhere without worrying about running out of fuel. We like to do long cruises to smaller towns/shows around here and most of the time its 100 miles + each way. I hate to say it but that's a tankful and some for me so I carry a can of this stuff and I'm covered.
I don't know why you would think that 825 cfm is small the way it's prepped. It's perfect. This engine has about 5K on it all street driving and lots of tire melting 3 gear burnouts. Plugs are perfect and it pulls clean and crisp all the way through the band. It's set up right for what it's used for. AS I mentioned above it's actually jetted down on the primaries one size and the power valve was swapped from a 5 to 3.5 to handle the lower vacuum signal at loping idle.
