Preparation Steps

Proper preparation is critical for a smooth installation. Work in a clean, well-ventilated space with ample lighting. Allow the engine to cool completely before beginning.

  1. Disconnect the negative battery terminal. Use a 10mm socket to loosen the clamp, then tuck the cable away from the battery post to prevent accidental contact.
  2. Remove the engine cover. On most Tundra models, the engine cover is held by push clips or plastic retainers. Gently pry it off and set aside.
  3. Drain the coolant. Place a drain pan under the radiator petcock. Open the petcock and remove the radiator cap to allow full drainage. Dispose of old coolant properly.
  4. Remove the factory intake assembly. Unclip the mass airflow (MAF) sensor connector, loosen the intake tube clamps, and remove the air filter housing. Cover the throttle body opening with a clean rag to prevent debris entry.
  5. Disconnect the battery positive terminal (optional, but recommended for safety).

Step-by-Step Installation

Step 1: Remove the Stock Intake Manifold

Begin by unbolting the factory intake manifold. Use a 12mm socket to remove the manifold bolts in a crisscross pattern to avoid warping. Carefully disconnect the following components:

  • Throttle body electrical connector and vacuum hoses
  • EVAP purge line
  • Brake booster vacuum line
  • Coolant hoses running to the throttle body (be prepared for spillage)
  • PCV hose

Once all connections are free, lift the manifold straight up. Install the gasket kit provided with the supercharger kit to the intake ports, but do not tighten yet.

Step 2: Install the Supercharger Base Plate

The base plate serves as the mounting foundation for the supercharger unit. Clean the engine deck surface thoroughly with a lint-free cloth and brake cleaner. Position the base plate gasket, then set the base plate onto the studs. Torque the base plate bolts to 12 ft-lbs in the sequence specified in the Edelbrock manual. Apply thread-locking compound to all fasteners.

Step 3: Install the Drive Pulley and Belt Tensioner

Most Edelbrock E-Force kits include a replacement serpentine belt and tensioner. Remove the old belt and tensioner. Install the new tensioner using the supplied bolts (torque to 18 ft-lbs). Route the new belt according to the diagram provided in the kit, which typically wraps the supercharger pulley, alternator, and AC compressor. Double-check belt routing; a misrouted belt can cause immediate failure.

Step 4: Attach the Supercharger Unit

With the base plate in place and belt tensioned, lift the supercharger unit onto the base plate. This step is easiest with a helper, as the unit is heavy (approximately 45–50 lbs). Align the dowel pins on the base plate with the corresponding holes on the supercharger. Lower it gently, ensuring the intercooler core and gaskets stay seated. Secure with the provided bolts, torquing to 84 in-lbs (7 ft-lbs) in a star pattern.

Step 5: Install the Intercooler System

The E-Force kit uses an air-to-water intercooler integrated into the supercharger housing. Install the intercooler pump and coolant reservoir as directed. Fill the system with a 50/50 mix of distilled water and Toyota-approved coolant. Prime the pump by cycling the ignition until flow is visible in the reservoir. This system removes heat from the charged air, so proper bleeding is essential for performance and longevity.

Step 6: Connect the Intake System

Reinstall the throttle body onto the supercharger inlet using a new gasket. Torque the throttle body bolts to 7 ft-lbs. Reconnect the intake tube, MAF sensor, and all vacuum lines. Ensure that air inlet ducts are tightly clamped and free of leaks. A loose connection can cause unmetered air, leading to lean conditions.

Step 7: Install the Fuel System Upgrades

The increased airflow from the supercharger requires additional fuel delivery. The Edelbrock kit includes larger fuel injectors (typically 42 lb/hr) and a modified fuel pump control module. To install:

  1. Depressurize the fuel system by removing the fuel pump fuse and running the engine until it stalls.
  2. Disconnect the fuel lines from the rail and remove the rail.
  3. Replace each injector, lubricating O-rings with clean engine oil.
  4. Install the new fuel pump control module (if equipped) as per the manual.
  5. Reconnect fuel lines and apply shop air to test for leaks (do not use starter during this check).

Step 8: Reconnect Battery, Coolant, and Check All Connections

Refill the cooling system to the proper level. Reconnect the negative battery terminal. Double-check every electrical connector, vacuum line, and hose clamp. Inspect the belt for proper tension and alignment. Use a torque wrench to verify all critical fasteners meet spec.

Step 9: Start the Engine and Perform Initial Check

Turn the ignition to the ON position without starting the engine, and wait for the fuel pump to prime. Listen for any audible leaks. Start the engine and let it idle for 10–15 minutes to reach operating temperature. Monitor the temperature gauge, oil pressure, and boost gauge (if installed). The engine should idle smoothly; a rough idle may indicate a vacuum leak or misaligned MAF sensor.

Tuning and Calibration

A supercharger installation is not complete without proper engine calibration. The Edelbrock E-Force kit typically includes a handheld programmer with a pre-loaded tune file. However, for optimal performance and safety, we strongly recommend a professional custom tune. Contact a reputable tuner such as D3 Performance or OZ Tuning to fine-tune air/fuel ratios, ignition timing, and shift points. Failure to tune the engine correctly can result in detonation, transmission damage, or engine failure. Always verify fuel pressure and wideband lambda readings during the first few dyno pulls.

Post-Installation Checks and Break-In

After the initial start, perform the following checks to ensure everything is secure and operating correctly:

  • Vacuum leak check: Listen for hissing sounds. Use a smoke machine or spray carburetor cleaner near gaskets and hoses while monitoring idle speed changes.
  • Belt tension: After a brief drive, check the belt tension. It should deflect no more than 1/2 inch at the longest span.
  • Intercooler system: Verify coolant flow by observing fluid movement in the reservoir. Air pockets can be removed by squeezing the hoses with the cap off.
  • Sensor data: Use an OBDII scanner to confirm that the engine reaches closed-loop operation, fuel trims are within ±10%, and no diagnostic trouble codes (DTCs) are present.
  • Test drive: Drive the vehicle gently for the first 50 miles, avoiding sustained heavy throttle. Gradually increase load to seat the rings and break in the supercharger.

Performance Expectations

When properly installed and tuned, the Edelbrock E-Force Supercharger Kit can add between 110–140 horsepower and 90–110 ft-lbs of torque to the Toyota Tundra 5.7L V8. Peak boost is typically 6–7 psi. Expect a dramatic improvement in passing power and towing capability. Fuel economy will decrease under boost, but highway cruising remains similar to stock. Maintenance intervals remain largely unchanged, though spark plugs should be inspected at 30,000-mile intervals due to higher cylinder pressures.

Common Pitfalls and How to Avoid Them

  • Overlooking fuel system upgrades: Using the stock injectors with a supercharger will cause lean misfires. Always install the included injectors and fuel pump controller.
  • Improper belt routing: Double-check the belt diagram. A belt that’s too tight can damage bearings; too loose causes slip.
  • Skipping the cooling system bleed: An air pocket in the intercooler system reduces cooling capacity, leading to high intake air temperatures and potential knock.
  • Neglecting a professional tune: The pre-loaded tune is a safe baseline, but a custom calibration from a tuner experienced with the E-Force system yields more power and safety.
