I know a few guys on here have been running e85 in their cars but I was curious as to what fuel pump they where using. I know for really high boost you will need either an external fuel pump, a booster pump, or go with a twin in tank set up but and what level of boost would you need to go to that. At what level would a single intank wally 255hp be good to? I was just curious, I've been running e85 in my del sol for a while now but its NA and doesn't have any real demands on the fuel system. Thanks for the input guys/gals!
