Torco race fuel concentrate?

Tryoing to decide final compression ratio for new setup.
I do not have easy access to race fuel. If I go high compression I will need to use this stuff or by drums of VP fuel. I like this approach as I can mix when needed.
According to torco I can get 107 with 32 OZ of this mixed with 6 gal of 93.
