Thanks to everyone who braved the WINDY WINDY conditions today and came out. The conditions today were worse than I've ever seen with 30 mph head wind gusts and periodic on/off rain. I appreciate the support of those of you who came out and ran. Having said that, I'm tired, and here are ALL the graphs from today! Enjoy! 
Matt Powell - C5 Vette - Big Motor, Big NOS - 5.27 sec. 60-130
Sebastien Robles - 94 Supra - Autobanh Single Turbo, E85 Pump Gas - 5.49 sec. 60-130
Sean Reed - 996 GT2 - GT30 Turbo's - 6.17 sec. 60-130
Paul Collings - 996 GT2 - Bolt-On Proto Turbo Kit - 7.25 sec. 60-130
Chris Powell - 996 TT - Bolt-On Turbo Kit - 7.29 sec. 60-130
Steven Caceres (sp?) - Supra - 67 mm Single Turbo - 7.74 sec. 60-130
Owen Priest - C6 Vette - Big Motor - 8.91 sec. 60-130
Matt Brooks - Trans Am - Bolt ons and 100 shot of NOS - 9.13 sec. 60-130
Justin Flack - GT-R (Godzilla) - Mid pipes and COBB tune - 9.96 sec. 60-130
This car also ran several 1/4 mile passes ranging 11.6-11.7@122-123 (without using launch control)
Chad Nall - 96 Viper GTS - Cat Back Exhaust only - 11.09 sec. 60-130
Matt Powell - C5 Vette - Big Motor, Big NOS - 5.27 sec. 60-130
Sebastien Robles - 94 Supra - Autobanh Single Turbo, E85 Pump Gas - 5.49 sec. 60-130
Sean Reed - 996 GT2 - GT30 Turbo's - 6.17 sec. 60-130

Thanks Peter! Wish I would have got in the 9's but the conditions were just not there. But I am very happy with my new best mph considering the conditions and progressing the nitrous for 5 secs. Thanks again for hosting the event I will be at the next one!

Advantage= E85 is like racegas.
Disadvantage= It takes more of it to make the same power, and it's corrosive to some of your factory fuel system. In other words if you run E85 with your current tune / fuel system the car will go LEAN, and over time it could be harmful to your fuel pump/lines ect.
Please feel free to correct me if i'm wrong on this.

Thanks everyone, The car has alot left in her. The only full pass was the first pass and I didn't launch because I didn't know how the track was going to hold the power (2.0 60' foot). We had the car dialed back alot nitrous had a 0.2 sec delay and started at a 100 shot and progressed to a 300 shot in 5 secs. Like I said this was my first and only full pass of the day and trap 147 with a 5.27 60-130. I pulled right around and didnt even shut the car off check bottle pressure and it was at 800psi didn't have time to bring it back to 950psi. Chris hopped in changed the progressive kept the 0.2 sec delay and made the car progress from a 100 shot to 300 shot in 3 secs. I launched the car at 3k but bogged to a 1.69 60' foot and by third gear I was pedaling the car and finally let out. That pass would have been a 9.9-10.0@149-150mph but letting off yielded me a 10.3. I tried two more attempts but the rain ended those. Thank God I didnt break and was able to make the hour and a half drive back home. I will be out next event hopefully with the new heads on the car and shooting for low to mid 15X's and somewere in the 9's and a 4.X 60-130.

Zac has it down pretty good. You will need ~30% more e85 vs gasoline to meet your fuel demands. Most people need 1000cc injectors to run e85 in evos with stock based turbos 400-450 whp. The race cars (600-700+) run double walbros with massive injectors and secondary rails.
Pros
- CHEAP racegas that can be found at the pump (http://www.e85refueling.com/location...&state=txTexas)
- The blends in Texas will probably never change this far down south
Cons
- Lower gas mileage due to increased fuel demand (must be tuned to richer a/f's)
- In high power applications you will need LARGE injectors and a nasty fuel pump setup
Some good info on energy comparison from a guy on Nasioc:

Power available on E85
Many sources make a big deal about E85 having less thermal energy per gallon that a gallon of gas. They frequently draw the false conclusion that you cannot make more power on E85 than you can on gasoline. E85 actually has a higher specific energy at stoichiometric fuel air mixtures than gasoline, and at proper max power mixtures releases more thermal energy in the cylinder for a given amount of air to burn. Since an internal combustion engines power output is primarily air supply limited this means you can make 5% to nearly 30% more power on E85 than you can on gasoline.
(edit 6/10/08) Current experience shows turbocharged cars like the WRX and DSM families can run upwards of 30 psi boost on E85 tunes without knock. The only case I know of where knock was logged was on a 500+ whp DSM running 35-39 psi boost!
Ethanol specific energy at stoichiometric fuel air mixtures is actually higher than gasoline allowing a higher release of energy per lb of air burned than gasoline.
Typical gasoline Thermal energy 19,000 BTU/lb max power fuel air mixture 12.5:1
Typical E85 Thermal energy 13,475 BTU/lb max power fuel air mixture 6.975:1
Typical ethanol Thermal energy 12,500 BTU/lb 6.429:1
If you are consuming 100 lbs of air, lets see how much fuel energy you release for each of these fuels using gasoline as the base 100% reference.
100/12.5 = 8 lbs of gasoline @ 19,000 BTU/lb = 152,000 BTU = 100%
100/6.975 = 14.337 lbs of E85 @ 13,475 BTU/lb = 193,189.9 BTU = 127% more heat energy
100/6.429 = 15.555 lbs of Ethanol @ 12,500 BTU/lb = 194431.5 BTU = 128.9% more heat energy
Typical fuel energy contents:
gallon of gasoline = 125,000 Btu
1 gallon of ethanol = 84,400 Btu
1 gallon methanol = 62,800 Btu
1 gallon of gasohol
(10% ethanol, 90% gasoline) = 120,900 Btu
1 gallon of E-85
(85% ethanol, 15% gasoline) = 90,500 Btu
1 gallon of kerosene or light distillate oil = 135,000 Btu
1 gallon of middle distillate or diesel fuel oil = 138,690 Btu
