"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 ...

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, ...

"Making horsepower is all about building adequate cylinder pressure," proclaimed Mike Dezotell of Dez Racing, as we embarked on our latest adventure into the world of compression ratios for boosted ...

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 per ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

Mechanical know how in our case has come largely from two sources. There have been those kind enough to show the way, and there has been the hard way. A long and proud lineup of 500-dollar cars has ...
