WHAT IS E-85 & WHAT BENEFITS DOES IT HAVE?

E-85 is an ethanol-based fuel that contains 51%-83% ethanol and is readily available at many local gas stations around the country. The main benefit of E-85 is its increased octane rating. The octane of E-85 will vary depending on the actual ethanol content of the fuel. However, most E-85 will carry an octane rating of 100+. This means that you can run more timing and more boost, which means more horsepower. E-85 is usually found at a cheaper cost than standard premium fuel. The combination of availability and cost of E-85 makes it a great option when looking to get more power out of your Mustang. However, this fuel does come with its own drawbacks. E-85 burns much faster than regular premium gasoline and will require 30% more fuel over standard premium fuel.

 

 

CONVERTING GEN 1 COYOTE (2011-2014 MUSTANG) TO E-85

When converting your 11-14 Coyote mustang over to E-85, you will need to do a few fuel system modifications for everything to run properly. You will be required to run a minimum of a 47lb fuel injector depending on your modifications. You will also be required to have a custom tune to support the E-85 and it’s needed fuel delivery. The factory fuel lines and fuel pump will support E-85 in a naturally aspirated application without issue.

 

 

CONVERTING GEN 2 COYOTE (2015-2017 MUSTANG) TO E-85

When converting your 15-17 Coyote over to E-85, it does not require as many modifications depending on the vehicle. 15-17 owners can run E-85 on the factory fuel injectors as long as they are running the factory intake manifold. You will still be required to have a custom tune to calibrate the PCM for the needed fuel. However, if you own a 15-17 mustang GT with an upgraded intake manifold, you will require a minimum of a 47lb injector. The factory injectors will not be able to withstand the fueling needs from the increased airflow of the upgraded intake manifold.

 

 

CONVERTING GEN 3 COYOTE (2018-2020 MUSTANG) TO E-85

When converting your 18-20 Coyote over to E-85, you will be presently surprised to know that you can pretty much go without touching your fuel system. Since the Gen 3 Coyote had direct injection, it has 16 injectors. This means you will have enough fuel delivery to support E85 and bolt-ons. The only time you will have to upgrade injectors will be if you intend to run boost and high-horsepower applications.

 

 

E85 + BOOST

At this point you’ve gotten a basic understanding as to what you will need for your Coyote to be able to run E85. But as you know, it doesn’t end there. BOOST!
Yes after you’ve maxed out your N/A gains on E85, most people tend to want to make the jump and add some sort of forced induction application to their car. So if you plan on running E85 on your boosted Coyote, you WILL need a complete fuel system (click here to find out which one works best for you!, including at least 1000cc injectors.
