![]() This new higher tolerance utilize tuning to increase boost pressure, ignition timing, and perhaps a leaner air-fuel ratio to produce even more power. With cooler intake air temperatures and less back pressure, the engine’s tolerance for detonation increases. Less power recovery needed reduces back pressure resulting in less propensity for detonation, less heat retained in the engine as well as better volumetric efficiency. ![]() This means the turbine does not need to recover as much power from the exhaust stream to power the compressor. As a result, water and oil temps can drop and that pressure drop across the core reduces the strain on the turbo’s compressor while reaching target boost pressure. Cooler temperatures results in a decrease in combustion temperature, moving the engine further from the edge of detonation under boost. Upgrading to a more effective intercooler will increase horsepower by improving intake air density and reducing thermal stress on the engine through cooler intake air temperatures.
