So thats my motor, what would you guys feel comfortable with (boost level?) running 91 octane and what timing to pull? .5/1psi or 1 degree per 1psi? I would like at least 10 psi but I know that’s probably at the line…
What about 107 – 110 octane using boostane additive? How does this change your timing plan and what is max safe boost?
E85 I will be running stock timing tables and run up to 15psi…. no issues other then my concern for the E85 vanishing and causing other issues. I don’t ride all the time so E85 could sit in the tank for a month, that’s concerning…
Hard to decide which route to go.
