Since gas prices are rising and race gas is mostly what we want to fill our tanks with, what problems would I run into running 111 all the time? Gas mixtures have changed so the relevance of prior threads is irrelevant today!

Another couple things to consider.

Do you really need to run race gas all of the time? Do you have any method of tuning, since your profile is empty? If you're running a fairly stock setup with a simple SAFC and daily drive it back and forth 10 miles to work through a city, I would say race gas would seem like a waste to run all of the time.

If you run a moderately or highly modified car, only on nicer days back and forth to work with some more open/free roads, then it might be worth it.


Also, do you ever plan to race the car? If you don't, I would see race gas as being another waste period unless your setup is a very high end setup requiring the gas.

If you do, depending on your tuning solution, you may be able to just run the race gas for race days. With ECMlink you can apply various tunes and could create a separate race day tune that has the car running leaner and higher timing to take advantage of the race gas.


If you do decide to run it and have to fill up on pump gas, this could cause serious issues if you can only drive the car hard. To fully take advantage of race gas, you need to really lean the car out and crank up the timing. If you're running 12:5 AFR's on the race gas, you should not switch to pump (i.e. 93) and go WOT with that tune.


Just some other things to consider. I sadly don't have any race gas near me in any pumps, which is why I rarely used to run it. With how little I drive my car though, I could afford to run it no problem, and would consider it if I didn't have E85 around.

Yes I see; I really dont put up all the mods done to my cars as I see it is always changing and I sadly don't want to show how much money ive dumped into my hobby.

This is the appeal of e85. Anything under about 600 hp doesn't require a ridiculous fuel system, and $3.00 a gallon is very attractive if you want to actually drive the car.

Now, for a ragged edge tuned race/weekend car, the higher end race fuels, and e98 are better options. But, as long as e85 is available, it's in all of my daily/semi daily drive turbo cars.

THIS ^ :thumb:

Also We can pick up E98 for about $4 a gal around here so I don't see the point of running anything but Ethanol... hell of a lot cheaper then any race gas even taking into consideration the drop in MPG... plus no worries of recalibrating my lc-1 after every 5 blocks I drive LOL

One of the guys on MM reported he was getting 10 mpg running E85 with his EVO. At that rate, he's spending quite a bit more to drive his car than I would running race gas. I sure hope you guys are getting better fuel economy with E85 than he is...

You have to be joking, i fill my car up twice for the cost of 5 gallons of decent race gas. It's actually about the same cost to run 85 as premium here in az, so race gas is not even close.

But, basically at a minimum a way to Tune & wideband, Walbro 255hp fuel pump an 30% larger injector vs gas for your goals... . An it's a good Idea to change out your fuel filter a couple times after the first couple tanks it tends to clean out all the crap from 20 years of gas.

Also the blend of e85 changes through the year between 70%-85% to help with cold starting in the winter.
although it's not that much of a issue for you being in FL the blend realy doesn't change.

Page 25 of This PDF shows where/when the changes take place

Same here, It actually use to be cheaper to run E85 for awhile after our station first opened up back when it was $0.99 a gal. or less. Of course pump 92 was cheaper then it is now as well though... .

Driving the about the same I have got the same mileage $20 gas vs $20 E85.

It's really a bad comparison though since someone running pump gas vs E85 is going to be more then likely running quite a bit more boost an driving harder I know I do LOL...

Cost me $3 a gallon for e-85 vs $3.66 for pump vs $75 for c-16......

My car also gets about the same milage between pump/e-85, im also not driving it everyday so a fill up will last me around 2 weeks!

We're not talking about the baller status race gas in this thread. We're talking about the $6/gal Sunoco stuff.

How do you explain that you get the same fuel ecomony when running a fuel that requires roughly 30% more volume to make the same power?

Have you actually measured fuel ecomony?

I run E-85 in the spyder and it is not my DD. I have different tunes one the AEM for lower and higher boost. When I have my foot down on the FP green that was in the car I got around 140 mp tank. Cruising on the highway 189 mp/tank (14 gallons). On the new set-up, 6262, when I beat it down 130mp/tank. When I cruise in it, 149 mp/tank. Also E-85 here is about $3.00 a gallon give or take a few cents....

Damn I can get real low mpg when I drive hard (which is most of the time) same goes with Gas. But never 140 miles to a tank... usually around 200-250miles with out completely emptying the tank say about 13-14 gal

But, Normal driving I get roughly 14mpg in town an 22mpg hwy. maybe a little better (putting around) as apposed to the 18 city - 28 hwy. I use to get on gas... also a note I almost always let the Talon warm up before driving at all.

I would imagine anyone running a real higher Cr like upwards of 10:1 would be getting better Mpg there actually are a few cars out these days that can get real close to the same MPG as gas. it's all about making use of the fuel with a higher effective compression ratio... .(That's the major flaw in most real Flex fuel cars today (a low Cr to run gas also)

wow i wish i had your guys prices, we have 92 octane here with 15% ethanol blend going for just over $4.09 a gallon. E85 is going for $3.599 a gallon and 100 and 110 race gas are BOTH going for $9.50 a gallon. To me the obvious best BANG for the buck is e85. However i can go up to english racing and get e98 for $4.00 a gallon! Im contemplating which way would be best for me with my knock happy setup and am leaning either e85 or meth/water injection! I just dont know if the meth will cut it. So far 4 gallons of e85 per tank suppresses my knock and allows me to add a bit of timing
