Where can you buy race gas in DFW?
taco bell?
There's a couple places. ECR sells it, but it's not cheap.
Motorsport Sales near 635/75 has a good rep and it's on your way home.
There's a bike shop north of 635 on the west side of 35 that sells VP fuels, but it's really pricey.
Kroger sells E85, which is 105 octane ;) I'll be running that in a couple weeks. It's 30 cents cheaper/gallon then 87!
Our local airport sell avgas 100LL for $3.55/gal. I don't know if you could use it in a race car.::Shrug::
So what do EVO drivers do when they switch to e85?Quote:

E85 is 105oct 30cents cheaper than 87oct but you do burn %20 more fuel i think.... It requires a complete upgraded fuel system but that also depends on how much boost yada yada yada. Its just a better alt. less worry about detenation and you can run more boost and such.
It better not have a catalytic converter in it. Also, 100 low lead avgas contains 4 times more lead than did regular leaded gas for cars. Even in aircraft you can have issues with fouling the spark plugs after a while.Quote:

I likely won't run much more boost (maybe one PSI more, I'm running 26psi now), but I'll be able to run quite a bit more timing, which will be nice since it will be power across the board.
Here's Chris from Cobb's dyno plot on his X MR converted to E85:

As you can see, 1psi of boost, but 71 ftlb tq and 52hp.
And Cobb's dyno reads lower than most (Mustang AWD, that's not calibrated correctly IMO).
20-30% more fuel is common. At WOT, because you're typically increasing the fuel delivery system it potentially is even more.Quote:

northstar drag way in denton has 104 octane no lead it was 8 bucks a gallon but the ms3 ran great on it.
Which brings up a good point - What are you going to do at the track when you burn through your tank of corn gas in a session and a half? Will you have an alternate map for normal gas?Quote:

Don't they have 100 octane gas at the Texaco at the front gate at MSR?
There's E85 within 15 minutes of H2R.
Chris
Yes, among others (well the last time I was there).Quote:

I use 50:Fuel in all my 2-cycle equipment at home (zero ethanol, all synthetic oil, fuel stabilizer included, pre-mixed to 50:1). It's nice having my blower and weedeater start on the first pull after sitting idle for 3 months.
Sorry for the off-topic rant. :D
E85 is the business (cheap and relatively easy HP).Quote:

Obviously this was not mandated for 2-cycle equipment.
Chris
Can we run 100 octane gas in a "regular" street car without tuning changes?
Actually, that's not true at all. The alcohol in E85 will destroy any seals in the fuel system that are made from natural rubber. Also, ethanol is an electrical conductor (gasoline is not), so it will promote galvanic corrosion between dissimilar metals (like steel and aluminum) in fuel system components.Quote:

Lots more good reading in that thread, looks like it's on pg. 51 now.Quote:
What about fuel system corrosion?
Corrosion does not appear to be an issue with modern OBDII cars. They are all certified by the manufactures to be safe to use on 10% ethanol fuel blends, and industry insiders say they are safe for much higher percentages. You don't install components that are "sorta safe" with a chemical, you put in a fuel hose etc. that is ethanol safe for concentrations well above what you expect to use. Not to mention that folks have been talking for years about raising the ethanol level to 20% or more.
Occasional use would be no problem at all based on my experience. I have never cut open the fuel filter (still have the OEM filter in place) I'll open it when I replace it. I want to put enough time on it to have conclusive evidence if there are problems.
(edit circa 2007 I cut open a fuel line and it looked like new, not changes or damage on stock rubber fuel lines in 2002 WRX)
The engine is not an issue with either, WI using a water alcohol mix or straight alcohol injection. In those systems alcohol and water are not used in significant quantity or for long duration. The Buick GN folks and lots of folks in the DSM crowd have done it for literally decades with no problems for the engine.
Many years ago there were studies that indicated engines that ran on alcohol ALONE as a fuel, had issues with lubrication and valve seat wear. Keep in mind, those studies were done a long time ago, when engine oils were much less sophisticated than they are now, and some engine manufactures in the 1940's,1950' and 1960's made stupid engineering decisions and did not use hard valve seat inserts like stellite in the cylinder heads. This resulted in valve seat recession problems if you did not have lead additives in the fuel to protect the valve seats.
