VRP M156 3.0L Supercharger Install Guide

Step 1:

Cut the o-ring material to length and insert into the inside slot on the left and right manifolds (approximately 21” or sp146) and tap in 4x dowels sp164

Step 2:

Assemble the lower half of the manifold connecting the runners to the center plate using the 8x M6 button head bolts with 3mm hex head socket (sp150)

Step 3:

Install the bypass valve onto the center section using 3x M6 bolts, and install Gasket material sp146 (approximately 31 inches)

Insert the flat o-ring into the bypass valve slot on the snout (sp162)

With Gasket material in, place bolt the lower manifold to the supercharger using 9x M10 bolts.

Install the o-rings into the slots on the runners for the intake ports.

1. Cut and insert gasket material into the top slot on the lower manifold. Use A Dab of RTV where the ends of the oring material meets. (see picture from 4.) (sp146, aprox 65”)
2. Remove your factory IAT sensor from the rear of your facrory intake manifold and install into the drivers side of the unit (Shown above infront of the supercharger on the left side of the image)
3. Remove your factory MAP sensor from the front of your factory intake manifold and install in the center plate of the main unit, (above the supercharger drive snout)
4. Install 2x 3” couplers to the rear inlets of the snout, Make sure the ends of the clamps are rotated so that the screws will point straight back to the firewall when installed.

Under the snout there are 2 connections, (One connection was moved to the rear of the snout between the intake tubes)

1. Banjo fitting – This will connect to the PCV valve connect a vacuum line to this banjo, You will cut it to the length of your catch can location, leave it long for now.
2. The first 3/8 fitting goes to evap
3. The second 3/8 fitting goes to the brake booster, you will use the plastic GM connector for that connection on the firewall.

The ports in the front of the unit are there for you to run boost references or whatever you may need them for. These simply get plugged with the provided 1/8npt plugs.

Prior to placing the unit onto the engine, put 2 more  T clamps on the silicone couplers, with the nuts pointing straight up, It will be very difficult to get them back there once its in the engine bay.

1. With assistance, set the supercharger onto the engine
2. Take note of what direction the injector connectors are pointing.
   1.  You MUST attempt to plugin the injectors BEFORE you bolt it down, otherwise you may have to undo everything past this step to rotate the injectors to clear the valve covers.

Use 10x sp155 with 6mm hex to install the supercharger to the engine. Add an o-ring to each

With the orange gaskets on the ends insert the intercoolers into the runners

Install the 4x Intercooler brackets to secure the intercoolers into the runners using 12x sp149 with 3mm hex

1. Cut to length and connect the Vaccuum line from the banjo fitting to your factory PCV.
2. Using the GM fitting for reference, pull a 3/8 line from one of the brass fittings to the Brake booster connection, Cut and connect.

Connect the final 3/8 line to the EVAP hose on the drivers side valve cover.

Install the Lid.

Place 3 orings into the center stands at the top and bottom of the supercharger opening.

Inspect the gasket installed previously to make sure it is still in place

• Put the lid into place and secure using the button head bolts provided
• 2x sp155 for middle rear
• 1x sp154 for center
  • 16x sp151 around lid.

Throttle Body Pipes

1. With the tube ends first, Slide the Intake Tubes behind the supercharger into the couplers and tighten the clamps down to hold the pipes in place, don’t fully tighten yet.
2. Install the throttle bodies to the ends of the pipes using 8x m6 bolts
3. Remove the factory Throttlebody harness from your factory intake manifold. Extend the short side of the harness approximately 10” to reach the passenger side throttlebody.

Tighten the clamps down with the throttle bodies in position resting on the valve covers

1. Install the oring gaskets to the front of the lower manifold where the coolant manifolds attach

Apply lubricant to the blue orings on the intercoolers

As this Image demonstrates, The passenger side manifold has 4 outlets, while the passenger side unit has 2. 

1. Install both coolant manfolds
2. Install the 10 orb to -10an straight fittings on the locations shown in red

Install the 10orb to Barb fittings in the locations shown in green (passenger side)

1. Connect the Barb Fittings to the Drivers side -10an straight fittings using the Barb to -10an adaptor fittings and the hose provided.
2. 2x 45* -10an fittings will attach to the passenger side -10an straight fittings, These should point town towards the front passenger side of the vehicle,

These coolant connections replace the version 1 setup shown here.

Connect the 2x 24* connections to your coolant circuit. Please refer to the diagram for hose routing

Fuel

Now that the coolant lines are in place, Connect your front fuel line loop under the supercharger drive snout

Run the remaining feed line from the back of the supercharger to the factory feed, Connect the barb adaptor fitting to the rail

Cut to length and connect the feed line

Power Steering

**This power steering solution was created post production please refer to the image below for mounting location,

Use the provided 5/8 and ½ fittings to connect your factory lines to the reservoir

Use your factory power steering lid with this setup.

Intake

1. Install the 2x 3.5” black silicone couplers to throttlebodys
2. Remove the Maf sensors from your factory Intake boxes using a small flat head screwdriver, pry the metal clip off of the flat side of the sensor. Install the Maf sensors into the 3d printed Maf adaptors reusing the metal clips from the factory intake.
3. Install the Maf adaptors to the throttlebody and plug in using the MAF sensor extension harnesses.
4. Install your desired intake setup to the Maf adaptors minimum of 3” piping recommended.

Heat Exchanger and Cooling

1. Remove the front bumper and install the Heat exchanger to the bottom of the crash bar using 4x self-tapping bolts
2. Attach the split cooling reservoir to the Radiator support bracket.
3.  Block off the small return on the bottom of the split cooling tank.
4. Install the Intercooler pump in a secure location and wire the pump to a switched power source
5. Run the rest of the system according to the diagram below
