From our rather limited research, it appears that building a performance street engine that combines a decent-duration camshaft with enough static compression ratio to create 175 to 190 psi, will ...

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 cranking compression numbers provide a good indication of its ability to run on pump gas without detonation.

Cold startability was measured for compression ratios of 14:1, 16:1 and 18:1 at 32°F, 14°F, and -4°F. The study indicated desirability of lower compression ratios for performance and higher ...

A compression test reveals the condition of your engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi ...

Is your engine underperforming? Our expert shares how a diesel engine compression test could provide the diagnosis.
