100+ Octane Fuel OK For 04 STOCK 13B?
I was thinking about bringing my Rx-8 to the drag strip and was wondering if its OK to run 100+ octane?

Unless you are running some form of FI, no reason to run 100+ octane. Engine is designed to perform optimally at 91-93 octane. Already in the upper range of performance. Unless you have a device that will alter/advance timing to the point you need higher octane gas, it is pretty much a non-issue.

OK to try it, just make sure it's UNLEADED.
Some race fuel and Avgas is still made with tetra-ethyl lead.
Lots of lead in your race gas will poison the cat, but more importantly will destroy the wideband O2 sensor the computer uses for mixture control.

OH REALLY! GEEZE AND ALL THIS TIME I WAS SPENDING EXTRA MONEY ON 97 OCTANE. Let me tell ya something. Why dont you go play stupid w/ that quitar, and remind your friends that you're a loser with no hope. People like you are a discrace to the integrity in forums.

actually he has a guitar has point, like I mentioned in the other thread, search. You will find that there has been a long debate about how rotaries can do without higher octane fuel due to its design.

Dissin' Guitarman......
Wow, Mr Hotrod -
Dissin the guitarjunkie just provides you with a special aura of "noobieness"!
This guy lives and breathes rotary, if the 'junkie says 87 will make more power, you can bank on it. Besides, most rotorheads already know this FACT. (So another layer of noobie for you.)
If I wanted a Renesis pulled out, ported, flowed and polished, then reinstalled in a hurry - I would see the GJ man.

well he does make a good point... i'm a loser with no hope. why do you thing i study engineering and play with rotaries all day every day? 
if i can get 320+ whp on 87 octane, why couldn't you get 175?
do some homework hotrods.

97% will always produce more horsepower than 87%. Scientificily Proven. Whats the point of race fuel then? Its for the extra performance, right? Yeah sure you can get some extra life from it, but whats the fun in that. Give me some Charts/numbers to show the difference, and I may be convinced. It just dosent sound chemicly logical, not on any combustable engine.
The comment seemed valueless, pointless and uncalled for. I'm new to rotarys YES. But have I've been hearing alotta BS messages hear an there and Occasionally will get some smartass remark from some class clown. And I thought thats what guitjunk was getting at. Honesty earns respect, Right? Sorry for bustin you chops though guy, Im sure you have many things goin, but its not my job to point those things out. Keep up the good work, and explain your position alittle more next time. And Watch out for those Hot tempered guys too.

if you are refering to octane.. where are you getting 97 octane????
maybe you could take the time to read around and learn more...
you are the one without the owners manual right???

for any given setup, the lowest octane you can possibly run without detonating is going to make the highest horsepower.
what you're thinking of is something along the lines of very high compression or turbo cars. with higher octane, you can turn the boost up and make more power.
higher octane fuel is capable of supporting higher horsepower, but it doesn't create it.
when i said 87 will make YOUR car faster, i meant it will make YOUR car faster....not some other car car with a different setup.
do your homework.
