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 ...

Most supercharger systems set at 10-12 psi, and with custom tuning will produce anywhere from 450 to 500 rwhp. We give credit to Ford for providing a suitable platform that incorporates three valves ...

Compression Ratio = Absolute discharge pressure/Absolute suction pressure Most technicians realize their service gauges read zero when not connected to a system, even though there is a pressure of ...

While we like to think of 2002 as being part of a high-tech age, our beloved internal combustion engine hasn't really changed much in the last 50 years. We're still using pushrods and overhead valves, ...

A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...
