I've been running e85 on my daytona since the end of August(08) with great success.
I originally had no plans to run it but when premium hit 4.25 a gal i had to do something, I knew it was out there just never really though about running it, well I did alot of reading on the fuel and what other people have tried(on other cars too no just td's) I started out adding 2 galons to see how it ran with 93oct mix, ran good, then did half a tank, then 3/4 a tank e85, then to full e85.
I'm running 40+ injectors, a walbro 255 fuel pump, all new rubber lines, new fuel filter since the first tank, with a custom cal that i scaled for e85, chem2 has the setting, although i make the injecter plus width above the preferred line, and also had to turn up my fp to 70psi

When it gets warmer out i'll play around with the pulse width more since I don't wanna play with it now being so cold and whatnot. I drove the car to Omaha and back(3hr drive i believe) with out a problem and ran multiply tanks though it plus....its 1.47 A GAL HERE


cheap, heck last time i gave a friend a ride he said he fill her up....13 bucks... sure it starts a lil rough with it being so cold but when we start getting the big snow/salt here its going to be parked anyways so no big deal here.
I suggest go for it, if you have the stuff upgraded do it, why not, cheap race fuel
