I am running a 50/50 mix of e85, in my car and all I can say is the torque is stupid! Will be going on the dyno soon but Virutal Dyno is putting me at 315-330hp/ and a quarter mile calculation gives me 324hp. Anyway the e85 tune is the only thing I have done to convert and have been running for 4000 miles now with nothing but a big grin on my face. A few guys are running 100% but being winter and on snow tyres I prolly will be going back to my 93 octane tune because I break the tyres free in fourth gear on dry pavement. I'll keep you posted on any progress or ills with this mod. MSF has a section dedicated to e85 Phate,Silvapain,and Dano are exploring this uncharted area.

As others have said don't do it unless you have/ are planning other supportive tuning fuel mods!!!
My bros about to 100% covert his R34 Skyline Track car to E85………… but by no means is there one standard component left in or on his car..... Or is it driven on the streets as a daily!!!
Like your thinking and to be unique but there's a lot more to it than simply "filler her up @ the servo"
