I've been using E85 for 3 years now without a problem. I don't think that the deatschwerks pump will be big enough to run E85 and 120's. I talked to the makers of it and he told me that 80's will be the biggest injectors that I can go and I may have to get a boost-a-pump also to be safe. I think you'll have to get double pumper atleast if you want to run 120's and E85. The reason I went with E85 was because besides straight race gas, 91 octane is the highest I can get here in Lincoln. Best part about it is much more torque and faster spooling. I did loose 3 to 4 mpg with it, but still cheaper then race gas.
Otes.
