“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 ...

Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at 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 ...

Formula 1 is entering a new era in 2026 because of its regulation overhaul, which is arguably the biggest in the championship ...

You've heard the term compression ratio before, but have you ever wondered exactly what it means? Well, it's time to explain exactly what compression ratio is, and why every carmaker is now obsessed ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

Now that we know how to calculate a compression ratio, let’s dig a bit deeper into what compression ratio physically means when applied to a cooling system. In reciprocating compressors, there must be ...

An unconfirmed theory about how Mercedes and Red Bull have circumvented F1’s power unit compression ratio regulations has emerged in Germany. Pre-season has been dominated by concerns that a loophole ...

A decision has been reached on the geometric compression ratios ...
