E85 and Back Pressure on Turbo Setup One of the big things keeping me from going to E85 this year is my concerns about back pressure. This is something that I've never really seen addressed on these forums.
My main concern is that the added volume of E85 that you need to burn when compared to gasoline much also produce extra exhaust volume. For a lot of people, like me, it seems as though this could produce a big problem if you're already on the edge of being out of turbine.
For example, my little TC76 with a .96 exhaust side is probably just about maxed out right now on 93 octane because of the small hot side. In my particular case, I don't know what E85 could really give me if I'm at the limit of the turbine side. More timing maybe, but is that worth it?
Just throwing out some ideas here. I have E85 local and all I'd need is bigger injectors as far as my fuel system goes. I just don't wanna shell out ~$1000 for big injectors to be let down in the end. And I'm not sure I really wanna swap turbos this season.
Let me know what you think.
