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 ...

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 ...

There's a fair bit of science behind how engine turbochargers do what they do (air pressure, compression, fuel burn efficiency, etc.), but basically it will improve an engine's power by around 30 to ...

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, ...

Over the course of testing, we had to make several passes at testing how these application-acceleration devices use compression to move the packets along the wire faster. Initially, we tried testing ...

Daniel Stafford;Nicholasville, KY: I've looked all over the Internet and asked the opinion of everybody I can think of, but I can never seem to get a definitive answer to my question. What is the ...
