“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 ...

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 ...

Stock car racing engines are all about efficiency. That's because all the simple solutions for making power have either been maximized or eliminated by the rule book. You aren't allowed power adders ...

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

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 ...

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 ...

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 ...
