Racing fuel in the rx8
Ive always used 93 octane in my 8 but i was wondering how racing fuel prob 100 octane will alter performance... Im just curious because its a rotary... Has anybody tried this? And what were the results?

Now Im talking about mixing race fuel with 93... 100 octane would certainly not work well but 95 or 97 might not be too bad and im buying an access port

First of all, avgas and gasoline designed for street use have their octane ratings figured in different ways. So the octane numbers are not comparable.
Secondly, oil mixed with gas LOWERS the octane rating. Think about that one.

Octane rating of a fuel does not equal energy content of the fuel, rather it is a measure of the fuel's tendency to burn in a controlled manner. Higher octane ratings does equal higher activation energies (energy input to start a chemical reaction), not increased energy in the fuel.
Switching to a higher octane fuel does not, in and of itself, add any more hydrocarbon content or oxygen, so the engine cannot produce more power. In fact, the substance used to increase octane generally reduces the energy content per unit of fuel.
Lead used in fuel currently is mostly for aviation gasoline, so not a good choice for cat equiped engines.

Even if you're catless, the lead will eventually destroy your Primary O2 sensor.
Then your car won't run and you'll find out how much they cost......
The un-turboed US engine is just fine at 91 (95 on the Japan/Europe scale)

this ^ and what team and stealth said are what you need to know. I suggest reading other octane discussions that include posts and links from me.
