When it comes to iconic racing engines, few of them can hold a candle to the Cosworth DFV, DFX, and their variations. A V8 that, at its largest displaced 3.99L and at its most powerful made nearly 1,000hp, it remains the winningest F1 engine of all time and the most dominating IndyCar engine of all time as well. The DFV was the brainchild of Keith Duckworth and Mike Costin, the larger than life geniuses that founded Cosworth Engineering in England. Drawn from a blank sheet of paper and refined into an engine that was largely unbeatable, it's a marvel of internal combustion magic. This is the complete history of this engine that had some unlikely roots, interesting predecessors, and an effect on auto racing that is still be felt today. A tiny engineerring firm in England captured the attention and sometimes the ire of the racing world with this iconic little V8, perhaps the greatest such engine ever made.

This is the story of Tommy Howes' 6.99-second quarter mile run at the 1988 IHRA Summer Nationals told in its complete form. From the tech that went into building the car, the men who tuned it, the context of doorslammer drag racing in the 1980s and more, it's the whole tale in detail. Few singular runs in the sport's history did what the Howes 6.99 run managed to do. It moved sanctioning bodies to make rules, it blew open an entire mechanical combination that was being largely neglected, and it set the path to the creation of Pro Modified as a category in stone. It's the story of a troll job, a wrecked funny car, a great NHRA division director, outlaw racers, and how drag racing reinvents itself every time it needs to.

This is the story of the most important racing engine ever built and how it lied to history for more than 70 years. In 1912 Peugeot built a racing engine called the L76. It was a groundbreaking piece of engineering and the first engine to use a hemispherical head, dual overhead cams, and four valves per cylinder at the same time. It dominated racing from the moment it showed up, but there was a plot twist. A journalist made a speculative report about the engine in 1912 and his claims would go on to take new life and spawn 70 years of false reporting on an engine few people had ever seen and no one was left alive to talk about. One man had a gut feeling that the history was wrong. This is the story of him, the engine, 70 years of fake news, and a 30 year mission to get it right.

The most monstrous WWII aircraft engine that you have never heard of is called the Studebaker XH-9350. A truly mind boggling project that Studebaker was the last option for when it began in 1942, it's an engine that would have been unmatched in aviation history had it been completed. Designed as an H-layout, it was to displace 9,350ci and make north of 5,000hp on gasoline. The engine was almost 10ft long and was over 100" wide as well. It was fed by two turbochargers that weighed 250lbs a piece and moved 14,500cfm of air. This is the story of the engine's background, its development including some incredible single cylinder engines, and interesting gearhead tech, and finally a look at why the Army Air Corps believed that they needed it.   Few have heard of this long lost project from the skunkworks of WWII.

Cummins diesel engines are an American institution. They've been one of the most massive manufacturers of diesel engines in the United States for more than 100 year now, but did you that they have an incredible history in racing, tied to the Indy 500. From 1931-1952 Cummins ran five different cars with five different engines at the 500 and all of them are amazing. Cummins is credited for more Indy 500 firsts than any other single person or entity in the history of the race. This is the complete history of Cummins at the Indy 500. Their most massive and well known headline was winning the pole in 1952 but that was a moment 40 years in the making. In this video you'll learn about the cars, the people, and take a deep technical dive into the engines that defined these events and Cummins as a company. These were production diesel engines mixing it up with racing engines on equal footing. It's one of the most surprisingly cool racing stories in American motorsports history.
