Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

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 ...

“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 ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...
