VRP M156 whipple supercharger upgrade for the C63 E63 CLS63 G63 AMG

VRP M156 3.0L Supercharger Install Guide

Part 1: Lower Manifold

To start, we are going to assemble the lower manifold.

You will need the center plate and both the left and right runner.

Step 1:

Cut the O-ring material to length and insert it 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)

Part 2: Supercharger Unit and Inlet

Next, we are going to assemble the supercharger unit and inlet

Step 1:

Install o-ring gasket material into the snout (sp161)

Step 2:

Install the Snout onto the Supercharger using 4x M8 bolts with 6mm head (sp142)

Step 3:

Install the Supercharger pulley using 4x M6 bolts with 5mm hex heads (sp130)

Step 4:

Install the banjo fitting, and both of the 3/8 barbs into the unit (The newest revision has 1 bottom port and one rear port on the snout, Install one barb fitting onto each)

Part 3: Combine Supercharger and Lower Manifold

First, fill the supercharger to the center of the viewer with Supercharger oil and remove any tape from the unit

Then, place the Supercharger on the table with the rotor opening upwards

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

With Gasket material in, 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 O-ring material meets. (see picture from 4.) (sp146, approx 65”)

      1. Remove your factory IAT sensor from the rear of your factory intake manifold and install it into the driver’s side of the unit (Shown above in front of the supercharger on the left side of the image)

      1. Remove your factory MAP sensor from the front of your factory intake manifold and install it in the center plate of the main unit, (above the supercharger drive snout)

      1. 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.

    Part 4: Fuel System

    Flip the assembled supercharger unit right side up. The next steps will be easier if you hang the back of the unit off the end of a workbench.

        1. Insert the 14mm injector spacers into the fuel rail

        1. Screw the 4 black ORB to an fittings into each end of the fuel rails

        1. Install your fuel injectors to the rails

        1. Attach the fuel rails to the sides of the unit. The rail with the fuel pressure sensor port goes on the driver’s side.

      Next, you will assemble Push Lock Fuel lines using the Aeroquip line and fittings provided

      The image below shows how to assemble the rear section of the fuel lines.

      VRP M156 whipple supercharger upgrade Fuel lines

          1. Screw the 90* fittings to the rear fuel rails and connect the 2 45* fittings to the Y, Holding the Y in the center of the Inlet measure for your lines.

          1. Cut 2 lengths of push lock line to fit the first 2 sections.

          1. The final section of the rear line cannot be measured until the unit is installed in the car, it will connect directly to the factory fuel feed

        The front line is very simple, The front line uses 2 90* fittings, and the push lock line. You want the front line to loop under the drive snout and leave some slack. (Your line will be blue)

        Measure, cut, and assemble this line now, but leave it off of the unit, as it will be in the way of the coolant manifold installation. (to double-check your length before you cut you can put the coolant manifolds into place and make sure the line will clear them)

        Part 5: Final Assembly Steps

        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 and connect a vacuum line to this banjo, You will cut it to the length of your catch can location, leave it long for now.

            1. The first 3/8 fitting goes to evap

            1. 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.

          Before 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 it’s in the engine bay.

          Part 6: Pre Vehicle Assembly

          Before moving forward:

              • Remove the factory Intake manifold

              • Remove the factory power steering reservoir, (Disconnect the lines at the reservoir)

              • Remove the Lift Bracket and Engine cover Holding bracket

            Rotate the rear breather tube 90* to clear the supercharger it is highly recommended that you use a Catch can set up for your breather connection

            Install the PCV Valve to the engine block as shown, (VRP catch can fitting shown) if using a catch can you can run this catch can line now keeping it against the firewall.

            On the passenger side remove the hard plastic cover from the wiring harness above the intake ports on the head.

            Remove the engine hoist bracket behind the valve cover on the driver’s side and cut the EVAP line as shown

            Locate the factory IAT sensor wire by the driver’s side valve cover, Cut and Extend the wires 24”(The new IAT sensor is located on the front inside of the driver’s runner, you will run the line under the unit

            Part 7: Installing Into Vehicle

            VRP M156 whipple supercharger upgrade IOV

                1. With assistance, set the supercharger onto the engine

                1. 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 Vacuum line from the banjo fitting to your factory PCV.

                    1. 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 driver’s side valve cover.

                  Install the Lid.

                  Place 3 O-rings 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.

                          1. Install the throttle bodies to the ends of the pipes using 8x m6 bolts

                          1. Remove the factory Throttlebody harness from your factory intake manifold. Extend the short side of the harness approximately 10” to reach the passenger side throttle body.

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

                        Cooling Lines:

                        **The coolant lines have been updated since this guide was made, The photos will not directly represent the fittings used as the manifold blocks now eliminate 90* fittings and T fittings

                            1. Install the O-ring gaskets to the front of the lower manifold where the coolant manifolds attach

                          Apply lubricant to the blue O-rings 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 manifolds
