“The Mustang ran great for more than a year,” noted Shrader. “In the quest for more horsepower, we pulled the engine out of the car to see just how far we could push the horsepower level out of a 4.6L Mustang engine which is street legal and still has a cold A/C. The most recent results were staggering. Running on summer blend E85, the car made 640 horsepower, measured at the rear wheels. With a typical 15 percent driveline loss, that is about 750 hp, if measured at the engine, compared to Ford’s dismal factory output of 260 hp.”
Although this car is not a daily driver nor built to be a commuter car, Shrader said it makes a nice weekend cruising toy and it still makes trips to the dragstrip for fun runs.
Shrader added, “The great results are largely contributed to E85’s 105 octane and cooler-burning characteristics, which allow us to really push the engine beyond what a gasoline engine can safely handle.”
Automobile manufacturers do not recommend converting a gasoline powered vehicle to run on E85.
