Powerama 1955: When GM Ruled The Earth They Put On The Greatest Horsepower Show of All Time

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.
