Turbochargers increase engine performance without adding much weight. Check out this image gallery to see pictures of how they do it.

Classic Chevy Engines

Take a look at the powerful engines that made the Corvette, Impala, and Chevelle hi-performance machines. Learn about the history and specifications behind these memorable engines.

Chevy 265-cid V-8 Engine

The Chevy 265-cid V-8 was a performance favorite for two generations. It was considered a benchmark engine design for its days. Learn about the history and specs of this marvelous engine.

Chevy 283-cid V-8 Engine

The 283 Chevy V-8 has become one of Chevy's most revered engines -- the definitive small-block enshrined by a generation of car enthusiasts who followed. Learn more about the fuel-injected small-block Chevy V-8 that powered the Corvette.

Chevy 348-cid V-8 Engine

Dubbed "Turbo-Thrust," the 348 Chevy V-8 was the largest and most powerful Chevrolet engine you could buy in 1958-61. These powered some of the most memorable of the "performance" Chevys.

Chevy 409-cid V-8 Engine

The high-revving 409 Chevy V-8 was a favorite of racers and hot rodders. Its most glamorous home was in the lmpala Super Sport. The 409 was the standard-bearer in full-size Chevys until 1965. Learn more about it.

Chevy 396-cid V-8 Engine

After doing surprisingly well in a 500-mile race at the Daytona International Speedway, the 396 Chevy V-8 was created as a high-performance option for the Chevelle and Corvette. Learn more about one of Chevy's milestone performance engines.

Chevy 427-cid V-8 Engine

Available for the Corvette and full-size Chevrolet in 1967, the 427 Chevy V-8 superseded the 396 with its aluminum cylinder heads with enlarged ports, hotter crankshaft, and bigger carburetor. Learn about one of Chevy's milestone performance engines.

Chevy 454-cid V-8 Engine

Chevy engineers had to bend some of their rules to get as much power out of the Chevy 454-cid V-8. America's "fuel shock" would ultimately sentence big-inch high-performance cars to oblivion. Learn about one of Chevy's milestone performance engines.

What if I pumped pure oxygen into my car engine instead of using the air in the atmosphere?

Engines need a certain amount of oxygen to make the car run. Exactly how much is needed? And if an engine used more, what would happen to the car?

What if I put a one horsepower engine into my car?

Most cars have a 120-horsepower engine, and SUVs have a 200-horsepower engine. But mopeds have a 1-horsepower engine, and they get great gas mileage, too. So why can't I put the small engine in the big car?

How Superchargers Work

Since the invention of the internal combustion engine, automotive engineers, speed junkies and race car designers have been searching for ways to boost its power. And they did, of course -- creating superchargers that make an engine more efficient by forcing air into the combustion chamber.

How Quasiturbine Engines Work

The quasiturbine engine takes the Wankel concept and improves on it: Instead of three combustion chambers it has four and the setup of a quasiturbine allows for continual combustion. Learn all about the quasiturbine.

Inside Engines

Our engine roundup page page takes you straight to the power. See what's under the hood from the HEMI to the Wankel.

How HEMI Engines Work

Even if you don't know much about cars, the word "HEMI" might still mean something to you. It's become a synonym for big, powerful engines.

What does 2.4 liter mean in the context of an engine?

This may sound silly but on the back of my car there is a little sign that says "2.4 liter" and every morning I see that and wonder "What does that mean?" So what does it mean?

How Stirling Engines Work

The Stirling engine is a heat engine that is vastly different from the internal-combustion engine in your car. It has the potential to be more efficient than most types of engines, but it hasn't made it into mass production yet. Find out why.

How do you convert engine torque to horsepower?

When you convert from engine torque to horsepower why is the number 5252 involved?

How Rotary Engines Work

A rotary engine is an internal combustion engine, but it's not like the one in most cars. Learn about the unique rotary setup and how it compares performance-wise to a piston engine.

What makes NASCAR engines different from street car engines?

The engines in today's NASCAR racecars produce upward of 750 horsepower, and they do it without turbochargers, superchargers or particularly exotic components. So how do they make all that power?

What does it mean when a car has dual overhead cams?

What does it mean when a car has dual overhead cams? Does it matter? Is a car with dual overhead cams better than one with single overhead cams?

How Fuel Injection Systems Work

As concerns about vehicle emissions and fuel efficiency have grown, fuel injection systems have risen to the forefront of auto technology. Trying to keep up with new environmental laws, carmakers began installing these systems in all new models.

How Camshafts Work

The camshaft has a huge effect on engine performance. It helps let the air/fuel mixture into the engine and get the exhaust out. Learn all about the camshaft and how a new one can radically change an engine's behavior.

Is there a way to compare a human being to an engine in terms of efficiency

Is there a way to compare a human being to an engine in terms of efficiency? For example can you calculate the equivalent "miles per gallon" (kilometers per liter) rating for a person riding a bicycle?

How Turbochargers Work

When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. A turbo can significantly boost an engine's horsepower without increasing its weight.
