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

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

With the combustion chamber being the root of all horsepower, it only makes sense that you start spec'ing an engine build there. One of the key variables in engine building is compression ratio, or ...

From June 1, the FIA will impose tougher tests on F1 power units in an attempt to clamp down on the compression ratio saga, ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

Harry Ricardo built the first known variable compression ratio engine as a test engine in the 1920s to study knock in aircraft engines. Variable compression ratio was achieved by raising or lowering ...

"Making horsepower is all about building adequate cylinder pressure," proclaimed Mike Dezotell of Dez Racing, as we embarked on our latest adventure into the world of compression ratios for boosted ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape. At the heart of the storm is a seemingly dry technical detail, the ...

Ferrari is planning to include a Mercedes-style compression ratio trick in the design of its new engine for the F1 2027 season, it has been claimed. It comes after it emerged last week that Mercedes’ ...
