INTRODUCTION
Before beginning installation, please read this manual and important notes:
•Please read the installation manual and verify that all items are present. If you are missing hardware or have any
questions, please contact your dealer or Whipple Superchargers before you start the installation.
•Modifications to your Fascia and Grill can greatly affect performance. Other aftermarket parts may also create issues.
The SC system is designed for stock vehicles.
•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!
•Operating your engine without the Whipple Calibration can result in engine damage or failure and will void your
warranty.
•Supply your VIN number (along with gear ratio, transmission type, throttle body type and any changes to vehicle) to
Whipple ahead of time so your unique PCM calibration can be built prior to the SC installation to minimize any down
time. NOTE: Whipple does not support long tube headers or cat removal. While the vehicle may run correctly, it will
no longer be emissions legal and therefore not supported.
• NEVER MANUALLY MOVE THE BYPASS ACTUATOR, YOU CAN RUPTURE THE INTERNAL DIAGHRAM.
•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.
RECOMMENDED TOOLS AND SUPPLIES
The following items are not included in this supercharger kit and it is strongly recommended that they're used for ease of
installation or maximum performance:
Engine Oil
Whipple highly recommends running Ford Motorcraft 5W-50 full synthetic motor oil (PN #XL-5W50-QGT) vs the stock
5W-20. You will need 10 quarts for an oil change along with a Motorcraft oil filter #FL-500.
Tools
¼” and 3/8” torque wrenches. Safety glasses, metric wrench set, electric or air drill, 1 ½” hole-saw, hack saw, ¼”, 3/8”,
½” assorted metric socket set, 5mm ball head allen, 3/8” assorted metric allen socket set, 3/8” assorted torx socket set,
8mm hex allen wrench, ½” breaker bar, flat head and Philips screw drivers and drain pan (for coolant). Heat gun or small
torch for heat shrinking. Electric tape. Trim pad tool (for pushpin removal). Clean shop towels.
Tie Straps
These will be useful for securing the wiring harness away from the installation area as directed in the instruction manual.
They are inexpensive and will be very handy during installation. You will need an assortment of 4”, 8” and 12”.
Sealants, Chemicals and Lubricants
Anti-seize for bolt and spark plug threads (use only when stated, otherwise the torque value must be reduced). Assembly
lubricant (white lithium grease or petroleum jelly). Cleaner/degreaser such as carb cleaner. Blue Loctite #243 or equivalent.
You’ll be required to fill your intercooler system with approx. 2.5 gallons of distilled water and Ford Factory specification
engine coolant. This is not supplied in the system, you can find the coolant at any local auto parts store. NEVER USE TAP
WATER, as it can corrode and create poor performance.

PRE-INSTALLATION CHECKLIST
Before installing your Whipple Supercharger Kit, complete the following checklist.
1. Vehicle Break-in: Brand new vehicles with sub 1000 miles should maintain OEM break-in procedures for the engine,
clutch or transmission. Applying extra stress to the power-train before proper break-in is not recommended and
could lead to damage which is not warrantable.
2. 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.
3. !! CAUTION !! This product is intended for use only on STOCK, UNMODIFIED, WELL-MAINTAINED
vehicles and engines. Installation on a worn-out or modified engine is not recommended. Custom
engine configurations are not supported, Whipple does not offer custom calibrations.
4. Verify Fuel System: Supercharger systems should only be installed on vehicles that have new or clean fuel filters.
5. 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.
6. !!CAUTION !! DO NOT remove the protective seal on the supercharger prior to installation. Foreign
material entering the supercharger will automatically void all warranties.
7. Identify Supercharger Kit Components: Before beginning installation, identify all the components of your Whipple
Supercharger Kit and ensure all items are present and undamaged.
8. !! CAUTION !! Do not attempt to start the engine before adding the supplied Supercharger Oil to
the supercharger!

WARNING!
VEHICLE MODS CAN CREATE RUNNING ISSUES
The 2018+ Mustang is Mass Air Flow (MAF) based. The MAF sensor is located after the air filter.
Changes to the flow of the airbox can greatly affect the airflow path, which creates potential fueling
related issues, especially at low airflow areas. Changes to the front grill/fascia and the factory airflow
path can create issues. Whipple does not offer custom calibrations based on aftermarket changes.
Example of a fascia mod that will greatly affect performance.
Stock fascia and grill has the main air feed through the center radiator area, the air makes a 90deg
turn to factory snorkel.
