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 ...

Even before the 2026 calendar year has begun, the first controversy under F1's new ruleset has already surfaced. It concerns the engine regulations, and more specifically the compression ratio of the ...

Formula 1’s new 2026 power units will debut at the Circuit de Catalunya in just over five weeks’ time, but questions over a grey area of the new regulations have already come to light. German outlet ...

The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Shown here are the component volumes that comprise the total clearance volume when the piston is at TDC. If the piston is domed or dished, that affects the clearance volume too. To measure both the ...

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 ...

The downsizing of engines by carmakers is a strategy that's now all too familiar. Over the past decades, many automakers have had to shrink their engine sizes as part of efforts to comply with ...
