15,000-HP Worth of Blown 526 cid MBR Engines

During the 2024 National Tractor Pulling Championships in Bowling Green, OH, we spent the weekend with Adam Koester of Miner Bros Racing Engines. Adam had a number of customers on the grounds that weekend, but this tractor, Blown Centless, owned by the Criswell family, was one Adam wanted to highlight. It has four 526 cid MBR engines on it, each boasting 3,800 horsepower! Adam gave us the details for this episode of Engine of the Week brought to you by @elringdasoriginal, @penngrade1motoroil830and NPW Companies.
