I NTRODUCTI ON
Before beginning installation, we encourage you to read this manual thoroughly before you begin any portion of the installation:

1. Your PCM requires an UNLOCK SERVICE FROM HP TUNERS. This HAS to be done prior to installing
supercharger to ensure no problems occur. DO NOT INSTALL WITHOUT UNLOCKING FIRST!!
2. A quick parts check to make certain your kit is complete (see shipper parts list in packing paperwork). If you discover
shipping damage or shortage, please call our office immediately.
3. Review our limited warranty with care.
4. Always wear eye protection during installation.
5. Avoid spills, if one occurs, clean up and dispose of towels properly.
6. Never work on a hot engine.
7. Obey all traffic laws when testing the vehicle.
8. Premium fuel (US 91 octane) is required to prevent spark-knock/detonation under certain operating conditions. Other
countries must meet US 91 octane standards, RON+MON/2. 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. The fuel system is returnless, therefore, initial fuel in the system will be low octane. Drain all fuel!

COMPETITION BASED PRODUCT MAY BE USED SOLELY ON VEHICLES USED IN SANCTIONED COMPETITION
WHICH MAY NEVER BE USED UPON A PUBLIC ROAD OR HIGHWAY, UNLESS PERMITTED BY SPECIFIC
REGULATORY EXEMPTION (VISIT THE “EMISSIONS” PAGE AT HTTP://WWW.SEMASAN.COM/EMISSIONS
FOR STATE BY STATE DETAILS.

COMPETITION BASED PRODUCT IS LEGAL IN CALIFORNIA ONLY FOR RACING VEHICLES WHICH MAY
NEVER BE USED, OR REGISTERED OR LICENSED FOR USE, UPON A HIGHWAY.

IT IS THE RESPONSIBILITY OF THE INSTALLER AND/OR USER OF THIS PRODUCT TO ENSURE THAT IT IS
USED IN COMPLIANCE WITH ALL APPLICABLE LAWS AND REGULATIONS.

R ECOM M ENDED TOOLS AND SUPP LI ES

The following items are not included in this supercharger kit and it is strongly recommended that they're used for ease of

P R E-I NSTALLATI ON CHECK LI ST

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

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 engines or modified vehicles is not recommended. Custom configurations can greatly
affect the operation of the vehicle.

3. Modifications to your stock vehicle including, but not limited to engine, flywheel, clutch, torque
converter, transmission, wheels, tires, axles, gears, driveshafts, air intake systems, exhaust system,
additional weight and aftermarket electronics can have a significant impact on your vehicles operation.
It is impossible for us to develop all possible variations and combinations. All vehicle and supplemental
warranties are based off stock vehicle configurations. It is the sole responsibility of the customer making
a warranty claim to prove that any vehicle modifications were within warranty. It is also the sole
responsibility of the customer to determine if the modifications comply with all local, state and federal
emission standards.

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. Flex
fuel/E85 is not supported.

5. Verify Fuel System: Supercharger systems should only be installed on vehicles that have new or clean fuel filters.

6. Assess Cleanliness of Installation Area: Make sure your work area and the under-hood 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. !! CAUTION !!
Do not attempt to start the engine before adding the supplied Supercharger Oil to the supercharger!

For the best result, it is highly recommended to use a Radiator Cooling System Vacuum Purge and Refill
Kit to properly evacuate the air from the intercooler system before filling the 50/50 mixture of coolant
and distilled water. If one is not available, the following procedure will be adequate.

The electric water pump used on the Whipple SC system has a built-in micro-processor that
will vary pump cycle speed when air bubbles are present in the system. If a significant
amount of air is trapped in the system, the pump may cycle at a lower speed and pulsations
are likely to occur resulting in poor cooling performance.

75. Using a Lisle 24680 Spill-Free Funnel, or equivalent, secure the appropriate filler neck adapter to the reservoir. Attach
the funnel and fill with a 50/50 mixture of coolant and distilled water until the funnel is half full. Whipple recommends
Zerex G-05 to match the stock color. The Whipple IC system is compatible with all common types of antifreeze, it is
customer preference. Note: Whipple also recommends 1 bottle of Red Line Water Wetter or equivalent. Never use
tap water, this will cause corrosion and destroy the system.

76. Turn the ignition to the ON position, after a brief delay, the electric pump motor will cycle. Air bubbles will begin to
rise to the reservoir, as the coolant level drops, continue to fill while pump is running. Once its done filling, turn the
ignition key OFF, the level will drop, top off with fluid. Reinstall filler cap and turn the ignition ON and let run for 15
seconds. Turn key OFF, remove cap to release air. Repeat until the filler tee holds at the cold fill level with key OFF.
To build more pressure in the intercooler system, try squeezing the intercooler hoses while the pump is cycling.
Building pressure in the system will help push the trapped air from the intercooler system to the filler tee. NOTE:
Do not let the coolant level in the funnel run empty as this may introduce more air into the system.

77. Cycle the ignition to the ON position again and repeat until the sound of the electric pump is continuous without any
pulsation and the fluid level is met at the filler cap. NOTE: During w ater pum p start-up, it is norm al for a
slight pulsation to occur. Once the pum p has reached its m ax im um cycle speed, no pulsations should
be present. I f any pulsations occur, there is air in the system . NEVER GO W OT UNTI L AI R I S BLED OUT!

78. Several drive cycles may be required to completely purge the air from the intercooler system. During a drive cycle,
the intercooler system will build up pressure as the supercharger temperature increases. Any residual air trapped in
the system will have to be bled out when the cap is removed. Use a rag when removing in case there is excess
pressure. CAUTI ON: N ever go W OT until air has been bleed from I C system , engine failure could occur
if not bled properly.

W ARN I NG: Alw ays avoid rem oving the filler neck cap w hen the system is hot. The hot coolant is under
pressure and m ay spray out causing burns.

79. Clean the inner area of the gas door with acetone. Attach the “91 OCTANE OR HIGHER” decal to the gas tank fill cap
or door.

80. Attach the negative cable to the battery and tighten.

81. Turn the Ignition key on, DO NOT START THE ENGINE. Inspect for any leaks such as fuel, coolant, and intercooler
coolant, correct as required.

82. Start the engine and let it idle for 30 seconds and then shut the engine off. Check the SC oil and correct if needed.

83. Start the engine and let it idle. The engine should idle normally between 600-700 rpm. Inspect for leaks. After running
for 2 minutes turn off engine and inspect the level in the ENGINE radiator and the Intercooler tank. With the key in
the ON position engine off, inspect the coolant in the intercooler tank, the coolant should flow in the tank. Top off
as necessary.

84. Before driving make sure that you have 91 or higher-octane fuel in the system. NOT ½ tank of 87 and ½ tank of
91, ALL 91 or better fuel in the system. Do not use octane booster in fuel to get to 91.

85. DO NOT use aftermarket air filter box or duct with the supplied Whipple calibration. The Whipple calibration is
designed to work with the factory air box, factory MAF and Whipple air inlet duct and nothing else. Changes to the
air inlet system will require a custom calibration which Whipple does not provide and is not 50-state emissions legal.

86. Install the supplied 50-state legal sticker to factory radiator shroud or on hood near factory emissions sticker. Clean
area with acetone or cleaning agent before installing.

87. Test drive vehicle for the first few miles under normal driving conditions. Listen for any noises, vibrations, engine
misfire or anything that does not seem normal. The supercharger does have a slight whining noise under boost
conditions, which is normal.

88. Re-check the radiator and intercooler reservoir coolant level regularly over the first 1,000 miles, top off level as
needed. NOTE: It is very common for installers to leave air in the system, if pump is varying in RPM, it
has air in the system.

89. After the initial test drive, go through the belt tensioner process again. When next you start driving, gradually work
the vehicle to wide open throttle runs. Listen for any engine detonation (pinging). If engine detonation is present,
let up on the throttle immediately. Most detonation causes are low octane gasoline still in the tank. Continued
detonation can cause engine damage, contact Whipple if you are having this issue.

90. If you have questions about your vehicles performance, please check with your installation facility or call Whipple
Superchargers at 559.442.1261, Monday through Friday from 8am to 5:00pm, pacific time or email questions to
tech@whipplesuperchargers.com.

 WARNING!! Verify the bypass actuator is working properly. To monitor, look at the bypass arm when the motor
is not running. Start engine and verify that the actuator arm has opened. This arm will be extended when the engine is
above 1” of vacuum (boost) and will be open when there is more than 1” of engine vacuum.

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 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.
4. Check the supercharger oil level at every engine oil change. Add Whipple SC oil to the supercharger if required. Do not
overfill the supercharger rear gear case.
5. Change the oil in the supercharger every 100,000 miles, if changing the speed of the SC, change oil every 50,000 miles.
Use Whipple SC oil only.
Severe dam age to the com pressor w ill occur if you overfill the supercharger rear gear case.
6. 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.
7. Inspect and clean your high-flow air filter element every 10,000 miles. Replace as necessary.
8. Check intercooler fluid level every 7,500 miles.
9. Replace spark plugs every 20,000 miles. Only run specified plugs, Denso ITV22 or NGK 6510 (.032” gap).
10. Follow your factory service intervals for oil changes and other typical maintenance items.
11. Check the supercharger/accessory drive belt. Adjust or replace as required.
Any m odification to your vehicle’s new com puter program m ay cause serious dam age to the engine and/ or
drive train.

CON GR ATULATI ON S
Your new Whipple Supercharger is engineered to significantly increase your engines power across a broad range of RPM’s.
It is Whipple’s 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 noise
