Stillen Supercharger Kit For 2007 350Z/G35
Stillen claims 410hp and 380lb-ft of torque with its supercharger kit for the VQ35DE engine (Stage Three with the Stillen dual path exhaust). The kit is CARB approved and eligible for optional three-year/36,000 mile warranty coverage (Stage Two only). The foundation of this kit is the same twin-screw supercharger used by OEMs around the world, chosen for excellent peak power coupled with superior low end and mid-range. The internal high-efficiency air-to-water intercooler design allows for more power and torque via a greatly reduced inlet charge temperature. This design also eliminates complex and cluttered intercooler piping. An internal bypass valve minimizes parasitic loss, resulting in a claimed 30 to 66 percent increase in useable power. An electronic control box is factory set to each vehicle and an auxiliary injector supplies extra fuel. With the Stage Three kit, more fuel is supplied via a high-volume in-tank fuel pump. Kits ship complete with all the necessary parts.
