2005 Cadillac CTS-V Supercharger Install - Supercharging Vinnie's "V"

The knock sensors were disconnected and the valley cover was removed.

After thoroughly cleaning the area, the supplied cover was installed and the knock sensors were replaced.

It's important to properly install the knock sensor wires, which must be glued down using silicone, and taped until the silicone dries.

While waiting for the silicone to dry, Vinnie removed the radiator and fan assembly.

Because the supercharger drive places extra load on the single accessory belt, it is necessary to reinforce the harmonic balancer by pinning it to the crank...

...The MagnaCharger kit includes a drill guide, drill bit, and hardened steel dowel pins so you accomplish the procedure easily.

The supplied balancer bolt was installed and tightened to 37 ft-lb of torque. Following along, we then attached a torque angle meter and rotated the bolt an additional 140 degrees.

Next, a small portion of the throttle body casting was removed (note grind marks on top of unit) and it was attached to the blower inlet.

Then the blower assembly was inverted...

...and we popped in the intake port gaskets.

Finally, it was time to install the polished MagnaCharger on the LS6 engine...

...The intake/blower assembly comes complete with 42-lb injectors, lines and the intercooler all in one neat package.

With the intake in place, the front engine dress, including the drive belt, was installed.

Vinnie and Faia dropped the radiator back into place. They also handled some of the wiring chores such as extending the wires to the IAT harness and the purge solenoid (not shown).

We got cool by fitting the supplied heat exchanger to the front of the Caddy.

Following that, we installed the system's coolant tank...

...and pump and we connected the supplied lines.

The pump harness was then wired into place.

Next, the Magnavolt box was wired into the trunk harness...

...and the box was mounted under the hood.

With the help of shop owner Joe Zappone, Vinnie filled the cooling system with the recommended GM coolant. We then checked for leaks. Thanks to a careful install there were none.

The front fascia was returned to its rightful place on the nose of the Caddy. By this point we were getting anxious. It was Monday night and I joked to Vinnie that I had to get home and watch my show that came on at 10 p.m. He laughed.

A smooth launch led to a best of 12.50 at 115 mph. That is haulin' for a 4,000-plus Cadillac on pump gas and standard street rubber. In the future, Vinnie plans to upgrade the tune and the exhaust. Are 11s possible?

With the polished MagnaCharger we totally improved the power, performance, and the underhood appearance of the CTS-V.

Vinnie utilized the OCC water jet cutter along with the in-house HAAS CNC mill to fabricate this unique plaque.
