Nissan Titan - Stillen Supercharger - Adrenalin Rush!

9. After all the wires and hoses were off, the intake was unbolted. The fuel line must be unhooked, which takes a special little tool, but don't get scared because Stillen sends one in the kit. You have to love getting tools with your parts.

10. The Eaton super-charger is a Roots blower, with one substantial design change; each rotor has been twisted 60 degrees to form a helix. These twisted rotors, along with specially designed inlet and outlet port geometry, help to reduce pressure variations, resulting in a smooth discharge of air and a low level of noise during operation.

11. One thing you will notice on the side of the supercharger is this black valve (A). It is a vacuum-operated bypass valve. Why does it need a bypass valve? This allows the supercharger to become extremely efficient in terms of economy and parasitic power loss. When vacuum is high (idle-cruising), the actuator opens the bypass valve, equalizing the vacuum pressure throughout the system. When boost is required during acceleration, the vacuum is decreased and the bypass valve instantly closes, causing pressure to increase into the cylinders. This equalized vacuum condition almost eliminates the normal parasitic power loss of a forced induction system. Pretty neat, huh?

12. The system also necessitates that you install the factory injector rail right below the supercharger's provided injector rail. That's right, this truck will end up with 16 injectors to feed the big V-8, and this is why a new high-volume pump was put in the tank.

13. The inlet housing must be installed. Instead of a gasket, a tube of liquid gasket maker is provided (A). The machining of these parts is like nothing you've ever seen, and the tolerances are so tight that a thin coat of this stuff is all that's needed (B).

14. The intake seals were transferred from the factory intake to the supercharger. As long as you are careful taking them out and don't tear them up, there should be no reason to get new ones.

15. The passenger-side timing chain cover was unbolted and set aside. The supercharger has a timing cover that will support the driveshaft. Make sure all of the old gasket is off the mounting surface or you will get a little bonus with your new supercharger, an oil leak.

16. Now for the shiny stuff, the supercharger fits right into the stock location, and as you can see, the timing cover is rotated out of the way, for now.

17. After a bead of gasket sealant, the timing cover was bolted up and torqued down to 96 inch-pounds

18. The fuel rails were tied together with these new hard lines, before being hooked back up the factory fuel line.
