Unhappy Predetonation

RE: "The 514 BB car is running on 93 octane. It has 10.25 : 1 compression"

I have some problems in 5th at ~2200 - 2500 RPM, especially up steep hills, and I only have 9.75:1 compression. I believe that an octane additive, to kick you up closer to 95-100 octane would help the part of your problem that sounds like predetonation.

Good luck on your dyno work this weekend
