This supercharger was created for the 5.4L Ford 32 valve engine, model years of 2007-2011. It has been designed and tested specifically for this application. Before beginning installation of this supercharger, first read this section carefully then complete the Pre-Installation Checklist.

Kit Components

Before beginning installation, be sure you have identified all components of your Whipple FRPP Supercharger Kit. Check the supplied packing slip.

PCM Flash (Complete Kits Only)

Your system includes a FRPP voucher. Follow the voucher instructions to get your flash tool shipped to you. It’s important to get this before you start your installation. Supercharger Oil

As described in the Illustrated Installation Guide, the supercharger must be filled with oil prior to use. This supercharger is shipped without oil inside. The oil is in a separate bottle supplied with your kit and you will be instructed to add it in the Illustrated Installation Guide.


Warning label attached to Supercharger housing


Do not attempt to start the engine before adding the supplied Supercharger Oil to the supercharger!

Pre-Installation Checklist

Before installing your Whipple Ford Racing Supercharger Kit, complete the following checklist.


Failure to complete the Pre-Installation Checklist may result in severe engine damage after installation is complete.

  1. Verify Condition of Vehicle: Before the supercharger kit is installed, ensure the engine runs smoothly and that the factory malfunction indicator light (MIL) is off. Only install the supercharger kit if the engine runs smoothly and the MIL is off.
  2. !! CAUTION !!

    This product is intended for use only on stock, unmodified, well-maintained engines. Installation on a worn-out or modified engine is not recommended without factory computer and fuel system modifications. Custom engine configurations could require custom tuning and other supporting modifications.

  3. Verify Fuel Octane: Ensure fuel of 91-octane or higher is in the vehicle fuel tank. If the octane grade is not known, drain the fuel tank completely and fill to 1/8th with fuel of 91-octane or higher.
  4. !! CAUTION !!

    Use only 91 octane fuel or higher. If fuel of less than 91-octane is present in the vehicle fuel tank, the tank must be completely drained and refilled with 91 or higher octane to 1/8th of a tank.

  5. Verify that your fuel level is below a ¼ full. When changing the fuel pump, this will be very important. If fuel level is above a 1/4 tank, then you will be required to drain fuel until you reach a ¼ tank or less.
  6. Assess Cleanliness of Installation Area: Make sure your work area and the underhood area are free from debris. This supercharger is a high-quality, close-tolerance compressor and must not be subjected to contamination by dirt or any type of foreign material. If necessary, vacuum around engine to remove any foreign material.
  7. !! CAUTION !!

    DO NOT remove the protective seal on the supercharger prior to installation. Foreign material entering the supercharger will automatically void all warranties.

  8. Identify Supercharger Kit Components: Before beginning installation, identify all the components of your Whipple Supercharger Kit and ensure all items are present and undamaged.
  9. Read Illustrated Installation Guide: Be sure to read through the Illustrated Installation Guide starting on page 6 before beginning supercharger installation. Familiarize yourself with the components and tools you will use and the procedures before you start for faster and easier installation.

For best performance and continued reliability it is essential to adhere to the following guidelines:

  1. Use only premium grade fuel (91-octane or higher).
  2. Always listen for any sign of spark knock or pinging. If present, discontinue use immediately and consult your vehicle owner’s manual.
  3. Do not overfill the supercharger front gear case.
  4. !! CAUTION !!

    Severe damage to the compressor will occur if you overfill the supercharger front gear case.

  5. Do not operate the vehicle at large throttle opening if the MIL lamp is on steadily. This indicates an electronic engine control malfunction: reduce throttle opening and consult your vehicle dealer.
  6. HIGH BOOST cars (19psi+) should inspect the actuator every 10,000 miles.
  7. Inspect and clean your high-flow air filter element every 7,500 miles.
  8. Inspect and replace spark plugs every 20,000 miles. Only run specified plugs such as NGK TR7IX for 12-18psi and NGK TR8IX for 19-25psi.
  9. Follow your factory service intervals for oil changes and other typical maintenance items.


Any modification to your vehicle’s new computer program may cause serious damage to the engine and/or drivetrain.



  1. Plunge the actuator arm into the actuator.
  2. Plug the top port with finger or rubber cap.
  3. Release the actuator arm while still capping the top port.
  4. Verify that the arm only slightly moved, if it went back to the closed position (resting on stop), then the actuator is ruptured/damaged and needs to be replaced IMMEDIATELY. If it checks ok, then re-install the 7/32” hose and secure with tie-wrap.

Servicing Your Supercharger

It is recommended that the following items be inspected at normal service intervals:

  1. Check the supercharger oil level at every engine oil change. Add Whipple SC oil to the supercharger if required.
  2. Check the supercharger/accessory drive belt. Adjust or replace as required.
  3. Change the oil in the supercharger every 100,000 miles. Use Whipple SC oil or Ford #XL-4 oil only. Follow these guidelines to properly maintain your Whipple- Supercharged GT500

Post-Installation Checklist

After installing the Whipple supercharger kit it is essential that the following checklist be completed.


Failure to complete the Post-Installation Checklist may result in severe engine damage.

  1. Review the Maintenance and service section and familiarize yourself with the steps you must take to ensure your Whipple-supercharged vehicle will continue to operate with optimum performance.
  2. Verify Fuel Octane: When you re-fuel your truck/SUV, ensure you use fuel of 91-octane or higher. It will always be beneficial to run 92-94 octane when available.
  3. !! CAUTION !!

    Use only 91-octane fuel or higher. If fuel of less than 91-octane is present in the vehicle fuel tank, the tank must be completely drained and refilled with 91 or higher octane to 1/8th of a tank.

  4. Check Vehicle Fuel Pressure: Fuel pressure is critical to proper supercharger operation and must be checked during wide-open-throttle operation when the fuel tank is 1/8th full. Fuel pressure should meet all factory specifications.

There are no warranties expressed or implied for engine failure or damage to the vehicle in any way during supercharger installation or use.

If you have completed the Post-Installation Checklist, you have successfully installed your Whipple FRPP Supercharger Kit.

Congratulations! Your supercharger installation is now complete.


Your new Whipple Supercharger is engineered to significantly increase your engines power across a broad range of RPM’s. It is Whipple and Ford Racings goal to improve your driving experience for many miles and years to come.

Whipple Superchargers operate as an air pump and contain internal rotors that are driven by the engine’s crankshaft and serpentine belts. The supercharger compresses outside air and channels it into the engine’s intake ports. Because of their design, superchargers may generate some additional noise over the standard, normally aspirated induction system.

At idle, you may hear a medium-pitch rattle from the supercharger main housing. This will diminish at about 400-500 rpm above idle. You may also experience a muffled high-pitched whine during acceleration. This is caused by the pumping action of the supercharger compressing air and only occurs during boost conditions. It is inaudible during part-throttle acceleration.

These are normal noises associated with any supercharger and have no effect on supercharger performance or engine durability. Your supercharger is warranted by Whipple Superchargers, please see your terms and conditions on the back of your invoice for more information in regards to the limited warranty. NOTE: Whipple Superchargers will not authorize any warranty repair work or supercharger replacement for normal noises.
