Premix for auto x??
#51
Some hydrocarbons have octane nubers as low as minus 160, but of course, pre-mix blenders tend to avoid them.
If you assume a worst case of your oil having 'zero' octane rating - then ten gallons of good 93 rated gas mixed (very rich) at 100:1 with would give an overall rating of 92.07....

We saw a little over 1.5 hp increase at peak power on 60hp (seriously) vintage Formula Vee motors by going down 4 points in octane. Is it possible that the RX8 could pick up the minimal power improvement noted by RB simply due to very slightly lower octane...rotaries are known to thrive on lower octane fuel, subject to detonation, of course...

As far as your mods.... It would be sad to think that you got a carbon fiber hood that weighs more than stock, and does nothing to improve cooling or intake airflow - I think in this section of the forum we might refer to that as useless bling. WOW, a mid-pipe that flows worse than stock, money well spent.
btw the mid-pipe does not put you in SM, a catted pipe is legal in STX/U, and a catless is legal in BSP.

No, the carbon fiber hood is what puts me into Street Modified. That's according to the chapter here local to Phoenix.
