Av gas is not the smartest idea to run in your sled it has difforent additives that can hurt your Moter just putting that out there.
This has been, well, debated and proven to death...both ways...
That being said, I know of plenty of guys running AV (100%) in turbo 4s with success.
And I've ran AV in 2 stroke mods over the years as well. 100% and at various mixes with 91 pump...
I've read plenty on the "motor rating", "research ratings", M+R/2 and such, AV 100LL would be a little yellow 100 if it were sold at a gas station pump..at least by what I understand and read about it.
heres a read on RON, MON, PON..

that being said, there are plenty of topics about AV being hard on O2 sensors and cat. converters..
then of course, heres some propaganda from a site / company that sells race fuel...for what its worth.

but a lot of things vary from "paper" to "real world".
