There are several places around Portland, a friend of mine Brian, has a Galant VR4 that runs low 11s(trap speed of high 10s) on E85, and he fills up at one of them.

In fact, Brian(and a bunch of other DSM/Evo people) should be out at PIR this Sat night, and I should be there as well.
Oh yeah, there is also Lucas English in Camas(englishracing.net) who runs E85-E90 in his daily driven 506AWHP '04 Evo, but he has a 500gal drum of E98 that gets filled up by a petroleum distributor. His fuel system is completely stock(other than 1000cc injectors, a 255, and his custom flash tune), and he's been running E85 for about a year.
Again I say(this is not directed at anyone in particular): YOU DON'T HAVE TO DO ANYTHING TO YOUR STOCK FUEL SYSTEM TO RUN E85(replacing the 20 year old rubber lines is a good idea even with gasoline though, hehe). Other than providing enough fuel for the engine via larger injectors/different calibration.
You can also run more timing with E85.
