Supercharging An Automatic Dodge Ram SRT10 - Blown Away!

Part One: Engine Prep
1. The install begins with the removal of the factory air intake, throttle body, throttle and cruise control cables, wiring harness, and vacuum lines. This enables the installer to remove the stock intake manifold. The stock manifold is removed using a combination of No. 30 Torx and 7/16-inch open-end wrenches.

2b. To solve the problem, the hub is removed using a 13/16-inch socket, and then using a jig supplied by Roe Racing, the snout of the crank is drilled so that a pair of roll pins can be installed. The hub is then reinstalled with Red Loctite on the bolt threads.

3a. Prior to installing the new intake manifold, the stock spark plug wires are swapped out for large-diameter MSD 8.5mm Superconductor low-resistance aftermarket units, because it's much easier to do the job then. New Bosch spark plugs with a colder heat range are also gapped at 0.032 inch and installed at this time.

3b. New 48-lb/hr injectors are also added to the mix, although the factory fuel pump is retained. The intake manifold runners are CNC-machined to line up perfectly with the cylinder heads. According to Roe, the intake has earned a U.S. patent for its design because it improves air/fuel mixture so much that the engine idles and runs more smoothly than it does in stock form.

Part Two: The Install
1. Once the gaskets and fuel injector wiring harness are prepared and in place, the intake manifold base is installed and secured, and the upper plenum and blower are ready to bolt in place. The parts are secured using socket-head Allen bolts and a 3/16-inch wrench, then they are torqued to 10 lb-ft.

1b. The blower is a 3.3L Lysolm twin-screw unit that comes in a black powdercoated finish. It's set up to produce a safe 5-1/2 pounds of boost that won't damage the factory pistons.

1c. Additional pulley combinations are available to increase the boost level, but this kit comes with a 2-year unlimited mileage warranty. The Lysolm unit is also self-contained with its own oil supply, making the installation simple and easy.

2. The front blower drive system is installed next. The drive support mounts to the engine via the upper alternator mounting bolt and a pair of the front timing cover bolts.

3a. Next, the throttle body is removed from the stock intake, cleaned, and installed onto the front of the supercharger.

3b. After the throttle body's mounting bolts receive a light coating of silicone sealant on the threads, the air cleaner is installed.

4a. After the fuel rails and injectors are set in place, the wiring harness is extended several inches and plugged back into the appropriate sensors. The manifold air pressure sensor and idle speed controller are both robbed from the stock intake and installed on the new parts.

4b. The Eaton bypass valve is mounted to the intake manifold and increases efficiency by providing instantaneous boost with zero lag at lower rpm.

5. Here's what the whole deal looks like once the installation is finished. A heat shield for the new air filter is provided. Although, before they are installed, the original air intake temperature sensor from the air inlet tube is installed into the new filter housing. The housing is trick because it uses the factory hood opening to direct fresh, cool air right into the air intake. The process can be accomplished at home in the garage with the right tools in a weekend, provided beer drinking and sports on TV don't get in the way too much.

6. Roe Racing's VEC3 allows the driver to instantly alter the computer programming by swapping out different Smart Cards. Each card has a different timing map, so it's easy to remove ignition timing advance to avoid detonation, depending on the weather conditions or what type of fuel is available.

With the installation finished, it's time to put the truck on the dyno and find out how hard Barry's ride is going to run.

Automatic
Barry's Quad Cab truck picked up an amazing 120 hp at the wheels, according to the chassis dyno, leaping from the weak 384 ponies in stock form to 504 ponies with the blower. That's a phenomenal increase for a bolt-on power part and one day of work.

Manual
In case you were wondering what the difference is between a manual tranny-equipped standard cab truck and the weaker Quad Cab version, we've included a dyno sheet here. This stick-shift truck put 428 ponies to the ground in stock trim and belted out a whopping 620 hp with Roe Racing's supercharger kit. Damn!
