ULTRA4 is the run-what-you-bring, no-holds-barred class that started King of the Hammers. Racing consists of rocks, sand, and all other manner of intimidating terrain, and speeds above 100mph are the norm. Cody Burge’s twin supercharged, ULTRA4 car that he brought to Holley LS Fest is one of the highest-horsepower cars in the class and certainly turned some heads. Nicknamed Medusa, the car is no joke and was certainly a fan favorite over the weekend.
