E85 Tuning?.....

[WagonR]

Hi guys,

Just finished up watching the Mighty Car Mods double unicorn build.

In the last episode, they tuned the engine with normal unleaded first then drained the tank and retuned for E85.

The difference was almost +50hp in favour of the ethanol but the car also ran out of fuel pump.

Have any of you tuned for ethanol from unleaded? What's required? It's some crazy gains by changing fuel.

For starters bigger fuel pump/s and higher flowing injectors as E85 uses app 1/3rd more fuel.

Not worth me even thinking about it, I have never seen an E85 pump in the fuel stations here in the UK
