Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the pistons in the cylinders.

Golf balls have dimples, so they fly farther than balls that don't. Apply the same principle to diesel engines, and you have a gross oversimplification of why dimpled pistons were invented. It's a ...

It goes up, compresses a violent explosion, and goes down. A piston's job is easy enough to understand, but if you examine what it's required to do, you may be amazed it works at all. Think about ...

Recently, I had an opportunity to spend a day with "Mr. Horsepower" Nick Arias Jr., while covering a tech article pertaining to an Arias engine he built some time ago. Nick Arias is a man of genius ...

While they're not quite ready for production, the printed parts were lighter, ran cooler and unlocked more power than the standard forged pistons. Antuan started out in the automotive industry the old ...

If you've been into cars for a while, you've probably swung a few engines over the fender that were assembled by someone else. That's cool, but it's probably about time to build one yourself. Overall, ...

Engine machining details reveal why some builders run pistons above the deck and how it affects compression and performance. #EngineBuilding #Racing ...

Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the compression ratio affect the engine?

Technical manoeuvring to push regulatory boundaries for the slightest performance edge without actually breaking any rules is a familiar pattern in all forms of motorsport. Engineers treat the rule ...
