Because of advantages like a better octane score and higher cooling capabilities, E85 gasoline is turning into a preferred alternative for prime efficiency engine builders and racers. And since E85 is usually cheaper and obtainable at native gasoline pumps, it makes E85 an much more enticing different to excessive octane race gasoline.
However how a lot of a efficiency enchancment can E85 gasoline truly present?
Nicely, the efficiency professionals over at Steeda Autosports got down to reply that query with some real-world dyno testing.
The Steeda of us begin with a mighty Fox Physique Mustang geared up with a constructed 438 Windsor working 13:1 compression. On the road with timing dialed again, the Mustang sips on 93 octane pump gasoline—however on the observe, it runs 110 octane VP racing fuel.
So what occurs whenever you fill the tank with corn juice?
Discover out as Steeda does a comparability check between the 93 octane pump gasoline, the 110 octane VP race gasoline, and a few strange ethanol-blend E85.
The video under is over 10 minutes lengthy and is filled with dyno pulls and horsepower/torque charts. As you’d think about there are timing changes, injector swaps, and different tweaks alongside the best way as effectively. Test it out, as a result of the outcomes are fairly darn stunning—and spectacular.
