Just curious to know how many ej255 owners with a vf52 on e85 still have their motors running with no issues. Please answer the following....
-How long have you been on e85? -Did your motor blow or is it still running strong? -whp/wtq figures.

I have a 2014 WRX on E85 making 330whp 400wtq. Had it at that level for 8k miles and the motor has been running fairly well but I haven't driven any other subies before.
As for the motor... I think it's fine but I've been monitoring my coolant overflow because it's pushing coolant and overflowing into the engine bay when pushed hard. I've been told it might be early signs of head gasket failure, but I got a koyo radiator in hopes that my stock one was beginning to leak. |

Nice numbers!! What ethanol cleaner do you use? Do you go back and forth from pump to e85 often?

Gummout! Haven't really researched this though.nope ethanol all year long! I would not hesitate if i were you. This is a "tried and tested" solution for subarus. :-)
Addendum Just realized you ve been running ethanol:-) Last edited by taxkourel; 05-13-2017 at 11:36 PM. |

I know this is for owners only but I am interested in the
longevity of engines and e85. From my research I can add that they seem fairly reliable with some large mileage figures (post 100000). I also note that as long as your source of e85 has a consistent rating you will see good numbers in the performance department. Up to 30% plus when compared to a vehicle with same mods running gasoline. |

Mine went out within a month. Baseline 91 came back with 50 less whp, but the E85 tune came out to 330/400. Car gave no issues of it going out, I was maxing out 4th one day and when I got off the highway I heard ticking. When I got back on to go home, it was a spun rod.
I never found out what caused it, but I never had any tune issues on E85. I cant wait to finish breaking in the new engine. |

I just swapped to flex / e85 yesterday, got the protune done in the morning with perfect SoCal weather.
2008 wrx Bone stock with a TBE ; dyno @90k miles (dyno dynamics) 208whp 222tq on 93pump Add VF52 new shortblock ARP head studs forged pistons PW Verticooler 3port ebcs invidia catless DP walbro 255 dyno (dyna pack) 270whp 308tq on 91ACN Added Cobb Flex Kit ID1050x injectors dyno (dyna pack) 311whp 360tq :tup: the propel station i went to got 75% ethanol based on the cobb sensor, car feels like a new animal with all that torque. im very happy with the car, on a conservative tune as it is a DD, and the corn is only 2.10$ so significantly cheaper then the ****ty 91 acn |

update. still same power. only use E85 fuel for past 2+yrs, @135k miles and on this setup.(vf48, id1000, walbro255, sti intercooler, protune.) runs like champ. has hiccups every now and then. new timing belt, plugs, coils. but now possibly pulley going out. (under boost sounds like I'm supercharged..) but motor over all is pretty solid. (high hopes) and will continue to daily corn. had set up for 32k miles so far. still pulls as hard as ever.
