Because this has become so critical, knowing how to accurately determine the true compression ratio of an engine is essential. That's what this Back To Basics segment is about.

We explore why a higher compression ratio means more power for your hot rod, and explain what to do to maximize that bump in power.

Static compression is what engineers, engine builders, and even do-it-yourselfers dial in to an engine build. Basically, it's the exact compression ratio formulated into engine construction in a ...

An engine's compression ratio is actually a theoretical number. This ratio compares the cylinder volume of the piston at bottom dead center (BDC) versus top dead center (TDC).

Variable Compression Ratio Engines have been some sort of a Holy Grail, and now Porsche proposes a viable solution for this ...

When should you get an engine compression test? Diesel engine compression tests aren’t a preventive measure, but are performed if you’re having issues with your machine. If your vehicle is ...
