Diesel engines are built to handle higher compression ratios than gasoline engines. This is because diesel fuel is more efficient at lower temperatures than gasoline. Gasoline will start to break down and detonate at high compression ratios, while diesel fuel can withstand much higher compression before detonating.
This means that diesels can handle more boost without damaging the engine. Boosting an engine increases the amount of air and fuel that is drawn into the cylinders during each intake stroke. This increase in air and fuel allows the engine to produce more power.
While boosting an engine does increase power, it also puts additional strain on the engine components. The increased pressure from the boost can cause premature wear on piston rings and cylinder walls. It can also lead to oil leaks and head gasket failure.
For these reasons, it’s important to consult with a qualified mechanic before increasing the boost on your diesel engine. They can help you determine if your engine can handle the additional stress and make any necessary repairs or adjustments beforehand.
