Introduction to RIPP Supercharger Installation

Installing a RIPP supercharger on your Dodge Charger is one of the most effective ways to unlock substantial horsepower and torque gains. The RIPP (Real Innovative Performance Parts) kit is designed for DIY enthusiasts who want to increase engine output without compromising reliability. This comprehensive guide provides step-by-step instructions, critical safety precautions, tuning recommendations, and post-installation procedures to ensure a smooth and successful upgrade. Whether you own a 3.6L Pentastar V6 or a 5.7L HEMI V8 Charger, the process follows similar principles—but always consult your specific kit instructions for torque specs and part numbers.

Before diving in, understand that forced induction demands meticulous attention to detail. Improper installation can lead to oil leaks, intake leaks, or even engine damage. We strongly recommend reading through the entire guide before lifting a wrench. For official product details and compatibility, visit the RIPP Superchargers official website.

Tools and Materials Required

Having the correct tools on hand is essential for an efficient installation. The RIPP supercharger kit includes many components, but you’ll need the following from your own toolbox:

  • Socket set (metric and SAE, including extensions)
  • Torque wrench (ft-lb and in-lb ranges)
  • Combination wrenches
  • Flathead and Phillips screwdrivers
  • Drill with variable speed (for any required bracket modifications)
  • Engine oil (synthetic, 5W-20 or as recommended)
  • Dex-Cool or equivalent coolant (check mixture)
  • Safety glasses and gloves
  • Shop towels and brake cleaner (for cleaning surfaces)
  • Jack and jack stands (for access under the vehicle if needed)

Depending on your kit version, you may also need a fuel system upgrade kit with higher-flow injectors and a fuel pump. RIPP often supplies these; if not, prepare to source them separately. Check the RIPP product page for your specific model for a full parts list.

Preparation and Safety First

Work in a clean, well-lit, and well-ventilated garage. Disconnect the battery negative terminal and wait at least 10 minutes for the engine control module (ECM) capacitors to discharge. Wear safety glasses to protect against debris and coolant splashes. Never work under a vehicle supported only by a jack—use jack stands. Keep a fire extinguisher nearby due to fuel system work. Review the factory service manual for your Charger to understand component locations and torque specifications.

If your Charger has an aftermarket tune or performance modifications, note that the supercharger will require a custom calibration. Contact RIPP or a professional tuner before proceeding. You can find community support on Charger forums for installation tips and tuning advice.

Step 1: Disconnect the Battery

Using a 10mm wrench, loosen the negative terminal bolt and remove the cable clamp. Insulate the terminal end with electrical tape to prevent accidental contact. This step is mandatory to avoid short circuits, trigger airbag codes, or damage the sensitive electronics during the installation.

Step 2: Remove the Engine Cover

The Charger’s engine cover is held by push-clips or bolts. For 3.6L models, it snaps off; for 5.7L HEMIs, use a socket or Torx bit. Gently lift the cover straight up. Set it aside on a soft surface to avoid scratches.

Step 3: Remove the Factory Intake System

Loosen the hose clamps connecting the intake tube to the throttle body. Disconnect the mass airflow (MAF) sensor connector and carefully remove the intake tube. Unclip the air filter housing from the fender well. Retain all fasteners and rubber grommets—you may reuse some for the supercharger intake routing. This is also a good time to clean the throttle body with carburetor cleaner if needed.

Step 4: Install the RIPP Supercharger Bracket

The supercharger bracket replaces the factory alternator bracket and provides a mounting point for the blower. Begin by removing the alternator (unbolt it and tuck it aside without disconnecting wires if possible). Then remove the factory bracket. Clean the engine block mounting surfaces. Apply thread locker (usually provided) to the bracket bolts. Position the RIPP bracket and torque the bolts to the specification in the manual—typically 37 ft-lb for M8 bolts and 55 ft-lb for M10. Double-check clearance with the water pump pulley.

Step 5: Mount the Supercharger

RIPP superchargers are typically centrifugal or twin-screw designs. Lift the unit into position on the bracket, aligning the drive pulley with the belt path. Install the supplied hardware and torque to spec. The belt should be tensioned according to the kit instructions—often using a dedicated tensioner. Rotate the engine by hand (using a breaker bar on the crank pulley bolt) to ensure the belt runs true and no interference exists with the fan shroud or radiator hose.

Step 6: Connect the Intake Piping

Attach the supercharger inlet pipe to the air filter housing. Use high-quality silicone couplers and constant-tension T-bolt clamps to prevent boost leaks. If the kit includes a blow-off valve or bypass valve, install it per the diagram. Ensure the MAF sensor is correctly oriented (flow arrow toward the engine). For non-intercooled kits, the piping is simpler; for air-to-water intercooler setups, you’ll also route coolant hoses and burp the intercooler system.

Step 7: Install Fuel System Upgrades

Most RIPP supercharger kits require increased fuel delivery. If your kit includes larger injectors, replace them one at a time to avoid mixing up connectors. For the fuel pump, you may need to drop the tank or access the fuel pump module under the rear seat—check the manual. Use O-ring lubricant and replace seals. A boost reference fuel pressure regulator (if supplied) must be connected to the intake manifold vacuum/boost line. Failure to upgrade fuel components can cause lean conditions and engine knock.

After completing fuel upgrades, pressure-test the fuel system for leaks before starting the engine. Turn the key to the ON position (without cranking) and listen for the pump to prime; inspect for drips.

Step 8: Reconnect the Battery and Preliminary Checks

Reattach the negative battery terminal. Tighten securely. Now is the time to double-check all connections: coolant hoses, vacuum lines, electrical connectors, and ground straps. Verify that the supercharger belt tension is correct and that no tools or rags remain in the engine bay. Fill the engine with fresh synthetic oil and change the oil filter (if due). Top off coolant to the proper level. Check power steering fluid and brake fluid as well.

Step 9: Start the Engine

With everything verified, start the engine. It may crank a few extra revolutions as fuel pressure builds. Let the engine idle for 5–10 minutes. Expect a slightly rough idle initially as the ECM adapts. Walk around the vehicle: listen for belt squeal, air whistles from leaks, or metallic noises. With a boost gauge (if installed), confirm that atmospheric pressure is read at idle. Check for oil leaks around the supercharger, oil filter adapter, and fuel lines. Shut off the engine and re-check all fluid levels.

If the check engine light comes on, use an OBD-II scanner to read codes. Common codes after supercharger installation include lean mixture (P0171/P0174) or MAF sensor errors—often corrected with a custom tune. Do not proceed to full throttle until you have a proper calibration.

Step 10: Test Drive and Break-In

Take a cautious initial test drive in a safe area. Avoid full-throttle runs for the first 50–100 miles. Vary RPM but stay below 4,000 rpm to allow the supercharger bearings and belt to seat. Monitor coolant temperature, oil pressure, and boost gauge. Perform a couple of moderate acceleration runs (half throttle) to ensure the engine pulls smoothly. If you experience hesitation, surging, or detonation (pinging), pull over and reduce load immediately—then contact your tuner.

After the break-in period, log a few full-throttle pulls and send the data to your tuner for fine-tuning. Many enthusiasts use HP Tuners or DiabloSport for custom modifications. For DIY tuning resources, refer to HP Tuners website.

Maintenance and Long-Term Care

Supercharger systems require more frequent attention. Change engine oil every 3,000–5,000 miles with full synthetic. Inspect the supercharger drive belt every oil change. Check for oil and coolant leaks. Clean the air filter element at 10,000-mile intervals. Also, listen for unusual bearing noises from the supercharger—a squeal or howl indicates servicing may be needed. Some RIPP units have a gear case oil that needs replacement every 50,000 miles. Keep records of all work.

Regularly inspect the intercooler (if equipped) for debris. Ensure that the intake piping clamps remain tight—boost pressure can loosen them over time. It is also worthwhile to perform annual compression and leak-down tests to monitor engine health. The extra power places greater stress on the internal components, so a well-maintained engine is critical.

Common Pitfalls to Avoid

  • Insufficient fuel pressure: Don’t skip the fuel pump upgrade. Even with larger injectors, a stock pump can’t sustain needed pressure under boost.
  • Boost leaks: Double-check every coupler and clamp. Use a smoke tester if possible. A leak will cause hesitation and rich/lean imbalances.
  • Ignoring tune requirements: Running a supercharger without a proper tune is extremely dangerous. The engine will detonate and fail quickly.
  • Skipping the break-in: The first few hundred miles are vital for belt seating and component adaptation. Push too hard too soon and risk belt slip or bearing failure.
  • Forgetting ground straps: Ensure the engine block ground is clean and tight. Poor grounding can cause sensor noise and electrical issues.

Performance Expectations and Real-World Gains

With a properly installed RIPP supercharger and correct tuning, a 3.6L Pentastar Charger can see gains of 100–130 horsepower at the wheels, pushing output to the 400–420 whp range. For a 5.7L HEMI, gains are even more dramatic—an additional 150–180 whp, reaching around 500–550 whp. These figures depend on fuel quality, ambient temperature, and whether an intercooler is used. Quarter-mile times typically drop by 1.0–1.5 seconds. The RIPP kit retains drivability as a daily driver when tuned conservatively.
