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 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 ...

With the combustion chamber being the root of all horsepower, it only makes sense that you start spec'ing an engine build there. One of the key variables in engine building is compression ratio, or ...

An engine's displacement dictates power output based on the bore and stroke, while compression ratio influences how strong ...

When comparing engine specs for nearly any combustion engine automobile, we see a number of variations available with differing outputs of horsepower and torque. We often have a choice of gasoline or ...
