One of the local tracks banned "racing fuel" in the "stock" class. And no additives allowed. Does anyone make pump gas with an octane rating higher than 93? Next question, how does one go about getting around this rule? And while we are at it, what is the most common way for them to tech this kind of rule?

Race gas will be dyed one color or another. Thats really the ONLY way to check it, unless they want to send it off to be anilized by a lab (expensive)

There is citgo (I think thats the store?!?!) stations out there that sell 107 octane out of the pump. Hard to find, but I have heard they are out there... NONE around here!!

Or you can run aviation fuel. Its high octane and contains lead, like race gas. Im not sure if it dyed or not, you would have to check that.

i run 94 pump gas with methal alcohol it helps bring the lead up and the octane but we r allowed the racing fuel. i have been running this combo for 6 years and like it much better than the racing fuel

If u cant run with the big dogs then stay on the porch!!

Pretty quick to declare "cheater" status there. knowledge is power with rules. As you saw was a 3 part question. We have to stay as fast as we can. Yet know our options, and know what the competition may be doing.

Most rules I've seen say pump gas only maximum octane 91 or 93 octane. The 2 tracks that I've raced at use a hydromiter (I believe that's what it's called) to test the gas, each octane rating has a different specific gravity.

That's not a very technical discription so I'm sure someone will correct it but that's the jist of how they tech our gas. I also understand this isn't the most accurate method available to test gas with however it is the cheapest. I have also seen tracks that with use the hydromiter then if your found illegal will send your gas off to a lab for a more accurate analysis and hold off their decision till they get the lab results.

Not quite what your looking for but this is how the way the super rules at one of the 2 tracks read just to give you an idea.

Pump and race gas okay. No nitrous oxide or other oxygen containing substances. Fuel is subject to spot check by tech inspector (specific gravity must be between 0.690 and 0.750).

hope this helps a little.

Your exact quote was how do I get around this rule. This means how can I cheat without getting caught. Don't get mad at me because of the things you say. It is pretty simple. If you can get it out of a pump then it is legal.

Torco lists specific gravity on their site if anyone wants to check it out. I assume it will test the same at the track. http://www.torcoracefuels.com/

jeramie, nice guy helps with the #32 car and this car will run on 93 octane. We have a few cars in this class that have high compression engines and won't make the cut on pump gas. By the way before you call other people "cheaters" how is that solid cam working for you sitting in the bottom of your oil pan? I thought we had a .480 lift hydraulic cam rule? If you need any help getting parts to put your engine back together give me a call. 574-8614
See ya at the track,
Duane

Sunoco makes 100 octance unleaded legal for street use. I don't know of any other 'pump gas' that meets EPA requirements and has street taxes applied. Sunoco's site says the 100 is it, http://www.racegas.com/gt100locals/default.asp There's a Sunoco about 15 miles from me that has the 100 in the pumps for $4.95, at least last I checked that's what it was.

You could pull a technicality and use the 100. It's street legal, has taxes applied and is available to anyone.

Also, if that's the only rule, you could run a huge cam and 11:1 or more on 93-94. You'd have to run at least 10-15 degrees more duration at .050" to bleed compression off, pull a couple degrees of timing and get a cold spark plug. And be really careful not to lug the motor below 3000. But, it could be done. Wouldn't be the ideal combo, but would be better than a 9:1 motor IMHO.
