Compression

Engine compression levels can positively or negatively affect power. It is important to understand compression and how it works with or against a particular engine system. Compression also has a direct effect on engine stress levels.

High Compression

Higher compression levels typically result in more power but at a higher risk. This is a good way to squeeze more power out of normally aspirated engine. Inversely, higher compressions are not suitable for forced induction systems as they will compound already high risk levels tied to boost.

Low Compression

Low compression pistons are made for forced induction applications. They are meant to relieve the engine stress that boost causes. Boost is required to compensate for the loss of compression. For this reason, low compressions will result in power losses on normally aspirated engines.

Tip

Select a compression setting based on your level of boost. Higher boost levels will require lower compression levels. Being accurate will make better power.
