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 ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

We put both engines on the dyno to see which made more horsepower and torque. It didn’t go as planned. Over the past year, we assembled two very mild small-blocks aimed at the typical hot-rodder ...

Formula 1's five power unit manufacturers are set to vote on a proposed tweak to how engine compression ratios are measured, which could come into force over the summer break. The 2026 power unit ...
