2008 Toyota Tundra TRD Supercharger Installation - 504HP Screamer

We were almost ready for the new TRD supercharger. This design is very efficient and features the blower rotors underneath the intake passages creating better airflow and a more dense air charge.

New rubber intake gaskets were installed onto each side of the supercharger.

With some help from fellow installer Jason, the large supercharger was lifted up and positioned into place. Each manifold bolt was torqued in sequence down to 15 lb-ft.

Each line that was disconnected was re-connected and the vacuum hoses repositioned and installed. We can almost feel the 504 hp coming from the big 5.7L.

Kurt then installed the factory throttle-body to the new supercharger manifold and reconnected the hoses and harnesses leading to it.

In went the TRD upper airbox and inlet hose for the intake.

TRD really did its homework with this kit and even included new Denso Iridium spark plugs. Each Denso IKH22#4 spark plug was installed at this time. The plugs were one step cooler helping the combustion with the added boost.

Upper heater hoses were then installed in the upper rear section of the supercharger. These hoses were ran to the front of the truck and will keep fresh coolant running through the manifold keeping the temperature down.

To gain access to the front of the truck, the grille and bumper was carefully removed.
