Saleen Series VI integrated TwinScrew supercharger with two-stage water-to-air intercooling system.
A second cooler located in the airdam below the engine radiator assists the intercooler integrated into the supercharger assembly. compact, light weight and high efficiency - Essentially, the Saleen design integrates the previously separate intake manifold, blower housing/assembly and intercooler into one compact unit that nestles neatly into the valley between the heads. This allows for a much wider intake manifold.
The shape of the "snorkel" opening for the intake air tube is designed for maximum flow. And to maintain a constant volume of air as the air flows toward the rear of the engine, the housing widens and lattens-out over the engine. All bends are opened up to provide smooth airflow.
The blower assembly contains twin screws, which push 2300 cc of air per rotation As a result, the supercharger turns slower for equivalent boost, producing lower stress and lower air charge temperatures. The higher supercharger efficiency, along with the lower air charge temperatures, allows for an intercooler that is smaller, lighter and more compact and which has virtually zero pressure drop from inlet-to-outlet side.
It features an integrated bypass for low-speed running; when you are driving at low speeds and don't require boost, the bypass helps reduce heat buildup in the engine. The Saleen design provides for optimal runner length, resulting in more torque and better low-end drivability.
It features long, beefy downdraft runners with minimal bends for maximizing torque and horsepower. The new design provides a straight, direct shot into the cylinders which maximizes airflow.
The overall efficiency gains-in the engine, the supercharger and the intercooler-mean the Saleen supercharged 3V-V8 produces more horsepower and torque at a less stressful 5-6 psi boost - 475 horsepower, and 450 lb-ft of torque.
