The Dork-O-Motive Podcast

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.

This is the story of how a 1979 AMC AMX won its class at the 1979 24 Hours of the Nurburgring. Not only that, how it was done with two hastily built cars, a group of six drivers that included a Hollywood star, and how they did it all on street tires. Oh, they also had a one armed German driving instructor. Not all publicity stunts are made the same and this video will be proof of that. In this case, Gary Pace of BFG had a big idea and teamed up with just the right people to execute it. Not only that, they had an ace up their sleeve which has gone largely ignored or simply not reported to this point in history. The first American team to ever compere at the 24 Hours of The 'Ring battled hard for 24 hours against the elements, exhaustion, their cars...and the competition? Watch and find out why that's the ultimate question

Incredibly, nitro powered drag racing nearly didn't survive the 1970s. It is a story often lost to modern history but it's a harrowing tale of shortages, price escalation, racer intervention, and the survival instincts of racers in Top Fuel and Nitro Funny Car. In this podcast we examine the tumultuous decade that saw performances escalate, star power grow, and in the end, the sport brought to its very knees as its most famous lifeblood was nearly stolen from it. Would you believe that many racers were advocating for its end in drag racing? They were and the proof is in here. Drag racing history isn't all about the records set on the track, it's often about the survival of its cars, of its venues, and of its fuel off of it.

It was late 1956 and craftsmen in Turin were thrashing to complete the latest, mosrt beautiful, and most complex project they had ever done for Chrysler. It was a concept car called The Norseman and it was both an exceptional design and a near impossible build. After missing its first shipping date, the job was finished a month later and the car ewas hurriedly placed on the Italian luxury liner Andrea Doria, one of the best known ships in the world, for its trip to New York City. No one outside of the factory in Turin that produced it had ever seen the car in person. It would be a grand reveal. The Stockholm was a much smaller ocean liner, in fact the smallest to be sailing the high seas in that class of ship at the time. A little more dowdy than the Andrea Doria, it was a tough ship with an ice breaking prow that could smash its way through just about anything. This is the story of the disaster that befell these two ships and sent one of the most beautfiul Detroit dream cars, concept cars, or idea cars ever created to the bottom of the sea forever.

The story of drag racing is typically seen as one defined by insane horsepower. The super fuels, the massive blowers, the acceleration that is unmatched by any wheel driven vehicle on Earth. But that actually isn't the root of the story. The real foundation of it all? Traction. And where did that come from? It came from tire shops at first. Taking old passenger car tires and gluing more rubber on them than they were ever supposed to hold. Next it came from a genius of a man from a small town in Massacusetts who quite literally invented the scratch built drag slick. And it's only gotten faster from there. This is the story of the genesis of traction. Of the birth of the one thing that drag racing has relied on more than nitromethane, more than superchargers, and more than steel tubing. Slicks. The tires that make drag racing the incredible sport that it is today.

f there is a story in American motorsports history more compelling than Micke Thompson versus the Indianapolis Motor Speedway, I am not sure what it is. The man conquered everything in his path over the course of a titanic career, except Indy. His ideas were wild, his concepts extreme, his timelines always stretched. In 1967 he would unveil a car so far out there that the media went crazy, the tech inspectors didn't know where to start, and engineers the country over scratched their heads. Front engine, front wheel drive, four wheel steering, and a driver seated basically between the rear tires, it was incredible. It was also powered by a custom made 3-valve small block Chevy. It was also doomed to fail. This is the story of the 1967 Wynn's Spitfire of Mickey Thompson.

There's nothing like upping the horsepower of an engine with boost. Multiple methods of supercharging exist today and have been brought to an incredible level of efficiency. While these methods were not invented in WWII, their use was vastly studied, tweaked, and tested to their limits back then. This video is the next in a series about the history of centrifugal superchargers and their use on piston engines. Consider this your 101 level course in WWII supercharging. Here we go over the various methods and systems used on aircraft from the USA, Germany, and Great Britain. Which countries did it best? Which country made a mistake in their method? Who ruled the horsepower roost and why? It was a war of horsepower and boost was a huge factor in making more of it than the other guys

In 1955 General Motors decided to put on a show, not just any show, a gathering of vehicles, horsepower, and entertainment the likes of which the world had never seen before and never saw again. Powerama was a one million square foot fantasyland of every off-highway division of General Motors on display. Dubbed the "World's Fair of Power" it had locomotives, bulldozers, elephants, aircraft, tanks, a submarine, pleasure craft, a shrimp boat, the Motorama dream cars, an 85-ton cannon known as Atomic Annie, and more and more and more. In this history we investigate the genesis of the event, the execution of the event, and the machines that made it one of the most unique gatherings in the gearhead history of Earth. Seriously, this is wild.

This is the story of an engine. Not just any engine, but the engine that created the idea of "American Muscle". It was the lightest, most powerful airplane engine in the world during WWI and it was designed by two guys in a hotel room during a five day marathon in Washington D.C.in 1917. Making 450hp and being produced by multiple American car companies, this engine was a master class in simplicity, integration of existing ideas, and mass production. While it can't really be said that it solved the war for the allies, what it did do was to introduce the idea of an America that stood as a colossus of industry among its peers in the world. The Liberty V-12 has an awesome story and the engine itself is worthy of your admiration.

This is the in-depth history of Hydrazine in the sport of Drag Racing. It is one of the most mythic, misunderstood, and undocumented stories of the sport's past. In this video we'll explore the origins of hydrazine, how it found its way into cars, how it enhances nitromethane and all of its associated dangers. Hydrazine was by far the most dangerous chemical ever handled regularly by drag racers and perhaps the most destructive as well. In this exploration, we bust myths, dive deep into the players who ran "The H" successfully, and document the cars, people, and events that were effected by it most. Using loads of period books, magazines, interviews, and history, the story is told in depth. Enjoy!

Nitromethane is the world's most powerful racing fuel but it's history and how it came to be may actually be more fascinating than its chemistry. Nitromethane was first made in a laboratory in Germany back in 1872 and as you'll find out, it's history goes far beyond the race track. In this multiple part series we'll explore the origins of nitromethane, why is it a miraculous chemical compound, how it found its way into race cars, its major uses around the world, and it's history that ranges from awesome to terrifying. We'll explore the myths, confirm some, disprove others, and take you inside this truly unique substance. Where did it come from? How is it used? Why does it work in engines? Who banned it? Who failed it ban it and why it scared people very badly in 1958. It's all here! A history of nitromethane...part one!

While the Liberty V-12 airplane engine of WWI is widely celebrated, there was another Liberty machine that has been all but forgotten. The WWI Liberty truck was designed and manufactured in great haste for an American Army that had all but forgotten to modernize itself before The Great War began. After chasing Pancho Villa around Mexico with a rag-tag fleet of hundreds of different vehicles in 1916 and early 1917, the US Army finally realized the need for standardized vehicles. An incredible national effort of engineering and manufacturing was put out to produce an order of more than 40,000 trucks in 1917 and 1918. But did it come too late? Could the nation answer the call? That's the crux of this story. The story of the WWI Liberty Truck is about the can-do spirit of a country wholly unprepared for war, the chutzpah of it's leadership in industry, and the idea that when the entire might of a country is thrown behind an effort, magic can happen. The lingering question though. Was it worth it?

This is the story of Walter Arfons' incredible Wingfoot Express 2 rocket land speed car. It's also a history of some pretty incredible rocket powered cars from the 1920s through the 1960s. Machines that raced on dirt tracks, performed at fairs, and even ran at the Indianapolis 500. The story of the creation of the Wingfoot Express 2 is one of perseverance, dedication, mechanical skill, and pure guts. It was a giant rolling science experiment designed to not only break the world's land speed record, but also break the sound barrier. To say that this thing was a glorious failure would be an amazing understatement. Imagine building the first ever JATO rocket powered land speed car from scratch at your home shop, having it break 500mph on the salt flats and still being labeled a failure? Rough, but we're here to tell you why.

This is the story of a company that is one of the most incredible in auto racing history. An operation known for making small engines for fire pumps, for manufacturing forklifts, and for creating marine diesel engines would become the most dominating F1 engine builder of the late 1950s and early 1960s. How did this happen? Why did this happen? Who MADE this happen? All those questions are answered here. You'll learn about the genesis of the company's racing program, the successful projects, the failed projects, the triumphs, and the brilliance of the people behind them all. Many people think Coventry Climax was an engine. In fact it was many engines and much, much success. A British company that was driven by passion, sometimes hidden passion, came to dominated the likes of Ferrari and all the others at their peak. This is truly a tale for the gearhead ages.

This is the story of the fastest car in the world in 1906. The first car to exceed 120mph and a machine that destroyed the most decorated field of automotive competition ever assembled to that point in history...and it ran on steam. The accomplishments of this short lived racing marvel are huge in the history of the automobile. The speed record it set stood as the outright automotive land speed record for four years. I t held the steam powered speed record for 103 years. Yes, 103 years. This is a historical exploration of the history of the Stanley Brothers, their car company, their adventures with steam, and ultimately their conquering of the world's land speed record with a car that used a body and frame made by a canoe company. A story of early automotive history, Yankee ingenuity, and plain guts, there are elements of tragedy and triumph you will never see coming.

The famed Novi V8 is one of the most storied engine in American motorsports history and also one of the most star-crossed. Massively power, innovative in its design and capable of making noise like no other engine in the history of the Speedway, it never won a race. But why? How does the most powerful engine for a two decade span not win...anything? This is a complete history of the Novi both in its developent and in competition. The people that made it, the technology that advanced it, and the issues that sunk it. If you have wondered where this engine came from, how much power it made and what its guts looked like, you'll know now. Built in incredibly limited number, they were gloriously and awesomely lauded by Indy 500 fans, no matter their record on the track.

This is a story about how five cars with no proper competition class, all running on nitro, crashed the party at the 1965 NHRA US Nationals and changed drag racing forever. This is the story of early funny cars, their search for acceptance, the resistance they had to battle, and how creative owners and builders got in making sure they got the attention and press they deserved. These cars were rebellious as much as they were unique. This is their story.

The Offenhauser four cylinder engine is one of the most incredible power plants in the history of American motorsports. It's basic design was conceived as a boat engine in the 1920s, making about 125hp. By the time it was all said and done, Offy engines raced into the 1980s and were making 10 times the power they were at first. The story of the Offy is so amazing because of the cast of characters involved in its creation, the fact that it survived so many attacks, direct and otherwise, on it from bankruptcies, to world wars, to racing rules and more, it survived and thrived. This is the history of the Offenhauser, from its origins to its heights of success in American racing and how this small engine crafted by brilliant minds and hands dominated competition in a way that we'll never see in racing again.

Ford's foray into the Indy 500 in the 1960s is a motorsports story for the ages. In 1963 the company used a pushrod engine derived from their successful 260ci small block V8. After nearly winning the race with that effort, engineers were turned loose to build the ultimate version of the engine. What they designed was dual overhead camshaft, 255ci V8 that made peak power at 8,000 RPM, was tested to within an inch of its life, and arrived at the Indianapolis Motor Speedway ready to win. While 1964 didn't go Ford's way, the engine would win 7 Indy 500 races, countless USAC events, and spur the development of a horsepower war that lasted into the 1970s with turbochargers and ever increasing speeds. This is an in-depth exploration, starting in 1962 of the development of this awesome engine.
