Anyone tried E85 yet?

Just wondering if the pump(s) and injectors have enough capacity.

I don't want to hear that it sucks or doesn't work. I know it does, I DD with it every day. I'm just wondering if any of the tuners who are working with the ST have done it.

Thanks.

Here's my question then. I have a '12 focus titanium that has flexfuel. Are the tank, in-tank pump and the lines the same as for the ST? I'm betting they are. Now all we have to find out is if the hpfp and the injectors can handle e85 like the v6 ecoboost can. Again, I'm betting they can, but I need to find someone in the know.

Talking sel with flex

I have used the flex and I find that it does misfired for the first miles or so. I find it really isnt worth it because you get way less mileage (flex250 mpt, regular398mpt). YOu do not want to be switching constently between types, that is way to hard on the car. I would use flex for long trips and stay with gas in town I hope this helps

The pump and Injectors in the 2013 Focus (ST) are large enough to make 300HP so yes they are large engough to handle the 30% more fuel needed

If the car isn't tuned for it then I wouldn't run it at all.

I would use caution with those thinking of using e85 in the ST

e85 isnt known for its octane but for its effects on cooling the air thus lowering the chance of knock , problem is the fuel is now sprayed directly on top of the pistons being direct injection at over 900psi now you dont have the time for cooling the air as much as you did when spraying into the valves + the 30% more needed fuel , the ecu can adjust for this but?

From your post and your SRT4 you sound like a big fan of E85. Can I ask why?
