Two main variables: 1) oxygenated or not; 2) Octane rating
I understand that oxygenated gas, you need to run richer (larger mains on carbed sled).... this makes sense.
i always thought that all things being equal, it was better to run 91 than 87. Now I'm hearing the firecat doesn't handle 91-93 octane very well, and that we should stick with 87.
SO MY QUESTION IS: What is effect of higher octane (burns hotter?) and how does that impact things...what are you guys using in your F7s.
THanks
