E85 on N/A subies?

mrchyes · 09-30-2012, 09:17 PM

first of all, is it even possible?

my tuner said it could happen, and could have good outcomes, but has anyone tried it?

he said i would need Stock STi injectors and fuel pump and his tune and id be good to go

is it worth a shot?

pretty sure you have to bump up injector size from stock stis on your NA. but dont quote me.

yes there are numerous people out here in CO that run e85 on NA cars, think of flex fuel trucks. and YES you will see a power increase

mrchyes · 09-30-2012, 09:26 PM

sweet, so maybe 750cc injectors?

how much of a gain do you think? worth seeking out the E85 stations? also is E85 more or less than regular?

So Thats the catch that you will run into.

YES you will easily be able to feel it. It will burn cleaner. Keep your car cooler and more reliable.

BUT! it burns around 30% more then 91. Right now in my town e85 is 3.39 and 91 is 3.99

So it is not more economical by any means! But i don't care cuz i run it year round lol! And yes you will also need a fuel pump too brother

The only advantage you are going to see on a NA motor is coming from increased ignition advance. Build a NA motor at 13:1 and make some real power on E85. The down side is that you are stuck only able to run E85 or race gas, if thats not a problem, why not go for it....

its really pointless to do on a stock n/a motor... the cost of the larger injectors, fuel pump, and tune isnt worth it for minimal gains and only being able to fill up at gas stations that sell it.

it only really makes sense to use in place of high octane race gas because it pays off when u can spend $3 a gallon instead of $10 a gallon.

mrchyes · 10-01-2012, 10:57 PM

i see where your coming from opey, that makes a lot of sense.

idk where the future of this car is going, more than likely something that isn't the average around here. Thats what i strive on

I did it just to do it. Bigger injectors and had a piggyback so I could control the MAF for fueling. NEver dynoed it though.
