100 octane: is it good for miata?
#24
Yes! This is pretty common for n/a guys, but for boosted guys this mean potentially more boost. The higher the octane the slower the fuel burns which give you more oportunity for HP, on the reverse side for a stock engine with you theoretically lose power as you are not releasing the same amount of energy from your combustion cycle.

I was assuming that it was already optimized for 87 and was simply pointing out how power loss could be minimized if the lower output from a higher octane fuel was related only to the burn speed and not the energy per unit volume of the fuel.
Edit: In addition it wouldn't matter on a stock engine anyway since you would need to massage the entire curve considering piston speed, and not just an overall change from moving triggers.
