Good link Steve. It is basically a discussion of how to raise octane. My question is more simple, WHY would you want to?
I know the main reason is: High compression and a fellow needs more octane. The Formula Fords are only 9.5 to 1 C.R., I suspect even "pump gas" would work fine (depending on timing issues, inlet air temperature, engine temperature, etc.).
Scott makes an interesting point, if I read it right. It suggests that there IS some "horse power" to be found using "race gas", a KEY part of the answers I'm looking for! Pretty hard to nail down WHY or HOW that extra horse power is to be had using "race gas" however.
