Installing a ProCharger System on a 2016 Cadillac Escalade

Power Packed

May 12, 2017

Every vehicle that is released to the public has gone through many years of testing to find that golden medium that mixes safety, comfort, reliability, performance, and economy. Each vehicle has a team of engineers that have spent, literally years, examining every inch of new vehicles to produce the perfect mix of desirable qualities. Once a level of acceptability has been reached, then and only then can the public stroll down to their local dealer and make a purchase.
We here at Truckin take all those qualities to heart, and we have great amounts of respect for the dedication those engineers have poured into every vehicle that bears their mark. But in one case, we have to respectfully disagree. We feel their agreed upon level of hp and torque is complete and total bunk. We know that we can do better, and we also know how to do it.
Photo 2/23   |   This ’16 Cadillac Escalade was about to get a whole lot faster with the addition of this High Output Intercooled Supercharger System from ProCharger (PN P-1SC-1). The billet impeller features an industry leading 4.10:1 step-up ratio, is fed by a two- or three-core air-to-air intercooler, has a patented self-contained oil design, and the entire system can produce measurable hp gains using pump gas.
There are many methods to create hp and torque gains, and we have explored them all. Many power-adding approaches are slightly off or you need to upgrade other areas to fully realize their promised increase. A few ways to add power are completely and totally foolproof, providing measurable gains with just their addition alone. One of them is to add a supercharger.
Just saying the word supercharger conjures up thoughts of clouds of tire smoke or pulling up to a stoplight with a sly grin on one’s face. A supercharger will do what it’s supposed to do each and every time and will do it with a minimum of fuss once the system has been properly installed. We picked out this ’16 Cadillac Escalade for this upgrade due to its imposing nature and stately elegance and because we also believe that this upscale family truckster deserves an uptick in horses and torque.
So we called up ProCharger in Lenexa, Kansas, to provide us with their High Output Intercooled Supercharger System (PN P-1SC-1) and on their recommendation, we drove over to House of Boost in Kansas City, Missouri, to have their highly trained techs handle this install. So follow along with us as we spend the day taking this ’16 Cadillac Escalade from mild to wild.
Photo 3/23   |   Here we are pre-surgery. Our ’16 Cadillac Escalade came to us with an unmodified engine. The ProCharger kit was designed to work within the parameters of the stock engine bay layout without any major modifications. And when we are done, the kit will look very unobtrusive.
Photo 4/23   |   Our first step in this install was to remove the stock airbox, Mass Airflow Sensor (MAF), and the air inlet. We disconnected the MAF harness, leaving the sensor still attached to the airbox. We then disconnected the PCV hoses on the driver and passenger sides, and set to work removing the air-inlet assembly.
Photo 5/23   |   After we removed the air-inlet assembly, we also disconnected the airbox tray and tossed it aside. It would not be reused.
Photo 6/23   |   A plastic cover on the ECU needed to be removed, as the ECU itself was going to be relocated to allow us to add the new air-inlet tubing and air filter from the kit. We removed the ECU in preparation to mount it into its new location.
Photo 7/23   |   Here, the ECU has been mounted into its new location. Included in the kit is a bracket that the ECU will be mounted to in its new location, which is down almost flat against the front of the wheelwell on the driver’s side to keep it well out of the way of the drive belts and exhaust components.
Photo 8/23   |   In order to mount the triangular sub bracket, we had to slide the wiring harness and brake booster line back far enough to allow the bracket to slide in place, and we bolted it in.
Photo 9/23   |   With the sub bracket installed, we now assembled the main bracket with its linear tension pulley, which had a vertical adjustment channel, to keep tension on the drive belt. We left it lose for now and would tighten up the pulley to the belt later on.
Photo 10/23   |   To access the space the intercooler would be mounted in, we removed the plastic splash panel. It is held in eight 10mm bolts, as well as two 15mm bolts.
Photo 11/23   |   Our three-core air-to-air intercooler was now ready to be installed, horizontally. The kit comes standard with a two-core ’cooler, but we opted for the three-core due to the lead-footed driver who would receive the Escalade after we are done. Since our Caddy was a ’16, we had to remove a tubular frame rod to make our intercooler fit. We removed two 21mm bolts, and out came the frame rod.
Photo 12/23   |   We installed the ’cooler bracket and bolted it into the rear splash panel boltholes. We also had to install a tube spacer from the kit on the driver’s side. We installed the rubber air dam to the bottom of the cooler and bolted in the aluminum support strap and the front intercooler brackets. With all that done, the ’cooler just slid right in, and we bolted it down good and tight.
Photo 13/23   |   This is what the completed charge-tube assembly looks like. Our installer is going to slide into place on the driver’s side. The filter is connected to ProCharger’s ProFlow bypass valve assembly. The top of this tube assembly will fit to the bottom of the supercharger, which has not been installed yet.
Photo 14/23   |   Here is a close-up of the bypass valve, which is designed to let off excess pressure when lifting the throttle. When the entire hose assembly gets snaked through, the 3-inch rubber coupler will fit onto the outlet of the ’cooler feeding the supercharger, and the ProFlow assembly will sit right in front of the outlet.
Photo 15/23   |   At this point, the PCV system is modified using the supplied parts from the kit and reinstalled. Pictured is the completed vacuum manifold, which has barbs for the surge valve, the PCV valve, and a provided check valve. The vacuum manifold itself is then tucked behind the injector harness to stay out of the way of the belts and pulley and zip tied down.
Photo 16/23   |   All of our preparation steps were leading up to the self-contained ProCharger P1SC1 head unit being installed to the main bracket with socket head cap screws from the kit and filled with oil.
Photo 17/23   |   With the supercharger firmly bolted in, we routed the supplied belt over the accessories and up and around the supercharger pulley. Moving the linear tension pulley as far down as possible, it was easy to slip the belt on. We used a 1/2-inch ratchet on the factory tensioner, rotated it counter clockwise, and slipped the belt over the alternator.
Photo 18/23   |   We went ahead and routed the tubing, starting with the 3 1/2-inch silicone coupler from the throttle-body, with the tube containing the mount for the MAF, which was then connected to another 3 1/2-inch coupler and routed to the intercooler. Our ProFlow assembly tubing was last to be connected to the supercharger’s outlet. We tightened up all the hose clamps and checked all the connections.
Photo 19/23   |   The MAF sensor was removed from the stock inlet tube, reconnected to the new ProCharger tubing, and screwed in using the factory hardware.
Photo 20/23   |   This supercharger install was starting to take shape! All that was left was to install the large-diameter cold-air intake onto the impeller inlet and clamp it down.
Photo 21/23   |   Our finished install could not look more tidy. It fits right in the engine bay with design and color elements that match the factory design scheme overall. And not only that, this proven supercharger system will produce measurable hp gains on the dyno, which is our next stop.
Photo 22/23   |   As a power company, ProCharger naturally has an in-house dyno to measure the results of their handiwork. The Caddy was run on the rollers before the install to get a real world measure of what the SUV produced in its stock form—a healthy 315hp and 321lb-ft.
Photo 23/23   |   After the ProCharger P-1SC-1 system installation, it was dyno’d again. With the addition of this High Output Intercooled Supercharger System, the numbers shot up to 501hp and 460lb-ft! This family hauling sleeper is now ready to drop unsuspecting drivers at traffic lights!
