100 octane
Wondering if I could get some imput on running 100 octane fuel. not as a constant, but when racing. Unlike all those against it and those who dont see the point, i do take my rx8 to the drag strip. nearest roadcourse is 3+ hours away, and where I live its what everyone does. Biggest thing is whether 100 octane fuel is going to help/hurt, seeing as I'm just using the stock computer. Any help/wisdom's appreciated.

He's as bad as Can
Why don't you make a few runs with 87, 91 ,93 & 100 Octane and post the time slips. Also 3 1/2 hours is not far to drive for a good road course. You will have more fun driving 25 minutes on a road course than 15.5 seconds in a straight line.

Once you get into 3-digit octane numbers you need to be tuned for it in order to get any value out of it. It won't HURT anything, it just won't help and with the money you save you can buy a couple of burgers at the track.

Actually the 100 octane fuel will help increase horsepower as it naturally burns more aggressively than normal pump fuel. I would use it for your racing even with stock ECU. However, as other fellow members suggested, if you get a custom tune for the fuel, you will get greater horsepower. But since you will drive your car on road everything, I won't bother for the tune just for using racing fuel.

i appreciate the responses. i reckon ill prolly run it next time around just to see since noone seems to think it will hurt anything. as for what yall seem to think about the price of it, 100 octane is available here for 2.55 a gallon, aside from 3.09 for 93 at the gas stations. next track day for me a some buddies is on the 10th. ill post slips an pics after that. stock was 14.5's to 14.8's, depending on how well i hooked up, though i no longer have those slips and the cars no longer stock. i will put the times up after the 10th though.

When you say you use 100 "Race Fuel" does it say 'for off-road use only"?
There are two kinds of race fuel, one blended from high-octane components, it's OK. The other is just doped up with TEL, the old Lead additive - will destroy your cat and both O2 sensors quickly. Don't use in the RX-8, EVER.

Are people simply disengaged from the process of discovery these days? I've tripped across sluggish people all of my life, but it seems the last 8 or 10 years have been riddled by individuals who are simply too transfixed by immediate gratification to even venture down the path of autodidacticism.

+1 The closest track to me is 30 minutes but the furthest tracj is 3 hours. I've made that 3 hour trip 3 times this season.

That's completely correct.
Member Doctorr works at a refinery in Canada and he has had some good posts on the subject:
https://www.rx8club.com/showthread.p...=octane+xylene
He describes the octane rating as a "resistance to detonation" not really an indication of the power contained in the gasoline. High octane gas can and often is lower in power.
The secret is to mix your own with Xylene a high octane AND high energy gasoline that way you know what is actually going into the mix.

Interestingly, the post you quote happens to be your own (cute, how many technical papers do you read where the author quotes himself). It doesn't really address Jason's question of whether he will go faster or hurt anything in his car by simply using 100 octane gasoline.
Try answering the person's question.
