Chevrolet Trailblazer SS Supercharger Install - Supercharged Super Sport

1. Before any parts were removed from the truck, we laid down a baseline test. The stock SS TrailBlazer peaked out at 333 hp, which is not too bad, but that's all about to change.

2. Simon started the teardown by removing anything that would prevent the manifold from coming off, such as the wiring harness and the fuel lines.

3. Once Simon had the area clean, he taped up the intake ports and swapped out the valley pan with the new billet piece from the kit. The new pan is completely flat, so there will be no interference with the supercharger when it goes on.

4. A small area of this accessory bracket needed to be ground down, and Simon recommended removing it from the engine to do the grinding. This will prevent the small aluminum chips from getting all over the engine compartment.

1. Because the LS2 crank pulleys are just pressed onto the end of the crankshaft, they will need to be pinned to prevent them from slipping on the crank once the blower is installed. Magna Charger provides this setup (inset) to help you properly drill the hole for the pin. The black piece you see is the drilling guide that will bolt onto the end of the crank. Here, you can see it installed, as Simon drilled the holes. Don't worry about drilling too deep, the provided drill bit has a step in it that will stop you at the proper depth.

2. Once the hole is drilled, a hammer and punch will be needed to drive the pin through the hole in the pulley and into the crank. This will lock the two pieces together and keep anything from slipping.

3. The new belt tensioner mounts to the passenger side of the motor and is from the same company that makes the original unit.

4. Some components from the factory intake will need to be brought over to the new unit like the throttle body.

5. Everything else is new, like the intake gaskets, which are installed right before the supercharger is set down on the motor. This will require the help of a friend; it's not that heavy, but it is awkward, and you don't want to damage any of the sealing surfaces.

6. With the supercharger in place, Simon moved on to installing the intercooler system. To access everything, the grille and bumper cover need to be torn down.

7. The pump (inset) for the intercooler was mounted to the front framehorn on the passenger side.

8. The reservoir was hung off of the upper A/C hose with two clamps.

9. The heat exchanger or second radiator slipped in front of the main radiator and was bolted to the core support.
