Upgrading the Nissan Titan engine with a supercharger adds a significant boost to its power. A Stillen supercharger, in particular, can raise a Titan engine's horsepower and torque from 317 hp to 390 hp and 385 lb-ft to 415 lb-ft respectively, according to Truck Trend. Other benefits include better air flow and more efficient fuel distribution. A minimal effect to gas mileage can be expected.
Stillen manufactures two types of supercharger kits for Nissan Titans built 2007 and above: Stage 1 and Stage 2. The Stage 1 model is an entry level variant that allows for the addition of an intercooler system after installation. It is available for Nissan Titans built from 2007 to 2015, but it is not considered street-legal in some states.
The Stage 2 kit comes equipped with an intercooler system and is legal for street use in all 50 states. It is the only forced induction kit to be approved by the California Air Resources Board. However, it is only available for Nissan Titan units sold between 2007 and 2011.
The Stillen supercharger kit for the Nissan Titan is the same unit used by other car manufacturers such as Ford, General Motors, Jaguar, Mercedes, Nissan, and Toyota. The installation process for the Nissan Titan supercharger kit is intricate and best left to a professional.
