Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

You’re not going to notice much difference here. It’s still a traditional four-stroke, internal combustion engine, after all. Just when you think we’re approaching a point where we can’t improve on a ...

What Happens When You Choose The Wrong Cam For Your Compression? See why camshaft selection needs to match an engine’s ...

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel ...

"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

The Porsche-Hilite technology is comparatively simple, and could be offered to every automaker if and when VCR comes to market. Share on Facebook (opens in a new window) Share on X (opens in a new ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

We all know the age-old maxim, "There's no replacement for displacement." It's the truth. That's why so many sanctioning bodies use displacement and compression rules to limit engine power. Of course, ...

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 ...
