Below is a comprehensive, step-by-step guide to installing the Hennessey V8 supercharger on your F-Type. We’ll cover everything from the tools you need and safety preparations to the actual installation, cooling system setup, and post-installation testing. This article assumes you have intermediate to advanced mechanical skills. If you’re not confident working with forced induction systems, consider having a professional shop perform the upgrade.

Tools and Materials Needed

Before you begin, gather the following tools and materials. Having everything at hand will make the process smoother and prevent unnecessary trips to the hardware store.

  • Hennessey V8 supercharger kit (complete with intake manifold, supercharger unit, pulleys, belt, hardware)
  • Metric socket set (including 8mm, 10mm, 13mm, 15mm, 18mm) with extensions
  • Wrench set (combination and flare nut wrenches for coolant lines)
  • Screwdrivers (flathead and #2 Phillips)
  • Torque wrench (capable of measuring in Nm and ft-lbs, range 10–150 ft-lbs)
  • Cooling system flush kit or coolant drain pan
  • Engine oil meeting Jaguar specification (check your owner’s manual)
  • Coolant (OAT or HOAT as specified by Jaguar)
  • Safety glasses
  • Mechanic’s gloves
  • Shop rags
  • Jack and jack stands (ramps acceptable for front-only lift)
  • Plastic trim removal tools (to avoid damaging interior or engine covers)

Preparation Steps

1. Secure the Vehicle

Park the F-Type on a level surface. Apply the parking brake and chock the rear wheels. Use a floor jack to lift the front of the car and place it securely on jack stands. Remove the front wheels for better access to the supercharger and associated plumbing if needed.

2. Disconnect the Battery

Disconnect the negative battery terminal located in the trunk. This prevents accidental short circuits and resets the ECU, which is beneficial when installing a new forced induction setup. Wait at least 15 minutes after disconnection before proceeding, as the airbag system and other powered components require time to de-energize.

3. Drain Engine Oil and Coolant

Place drain pans under the engine. Remove the oil drain plug and let the engine oil drain completely. Remove the radiator drain plug or lower radiator hose to drain the coolant. Dispose of fluids responsibly. This step is essential because once the supercharger is installed, you’ll be adding fresh fluids.

4. Remove Engine Covers and Air Intake System

Take off the engine beauty covers by prying them upward with a trim tool. Disconnect the mass airflow (MAF) sensor electrical connector, then unclip the intake air duct from the throttle body to the air filter box. Remove the entire air filter housing (two bolts at the bottom). This gives you clear access to the stock supercharger assembly.

Removing the Stock Supercharger

The stock supercharger on the F-Type is a Roots-type unit mounted on top of the engine. Removing it requires patience and careful attention to wiring and hose connections.

1. Disconnect Sensor and Vacuum Lines

Carefully unplug all electrical connectors from the throttle body, supercharger actuator (if applicable), and manifold absolute pressure (MAP) sensor. Label each connector with painter’s tape to avoid confusion during reassembly. Also disconnect vacuum lines that run to the brake booster, PCV system, and boost reference ports.

2. Remove the Throttle Body and Intake Ducts

Unbolt the throttle body from the intake manifold (four 8mm bolts). Gently pull it free and set it aside. Remove the intake ducting connecting the air filter boxes to the supercharger inlet. On the V8 F-Type, there are two ducts – one for each side. They are secured with hose clamps.

3. Unbolt the Intake Manifold

Using a 13mm socket, loosen and remove the intake manifold bolts in a cross pattern. There are typically 8 to 10 bolts. Once all bolts are removed, lift the intake manifold straight up. Be careful not to damage the gasket surfaces. If the manifold sticks, use a plastic trim tool to gently pry it loose.

4. Remove the Stock Supercharger Unit

The supercharger is bolted to the engine using four main bolts (plus additional smaller bolts on some versions). Locate all bolts and use a socket with an extension to reach them. Remove the bolts and carefully lift the supercharger off the engine. It is heavy – you may need a helper. Place the old supercharger on a clean surface, as you may want to inspect or sell it later.

Note: The Hennessey kit replaces the entire supercharger and intake manifold assembly. Do not attempt to reuse any gaskets or seals from the stock unit. The kit includes new gaskets.

Installing the Hennessey V8 Supercharger

1. Prepare the Mounting Surface

Clean the engine deck (the surface where the supercharger sits) using a lint-free cloth and brake cleaner. Ensure no oil, coolant, or debris remains. Any contamination can cause a vacuum leak.

2. Position the Hennessey Supercharger

Place the new Hennessey supercharger gasket (provided in the kit) onto the engine. Then carefully lower the supercharger unit onto the engine, aligning it with the dowel pins and bolt holes. It should sit flush without forcing. If it doesn’t, check that the gasket is properly aligned and that no wires or hoses are trapped underneath.

3. Secure the Supercharger

Hand-thread all mounting bolts first, then torque them to the manufacturer’s specification. Hennessey recommends 27 Nm (20 ft-lbs) for the main bolts, but always verify with the instructions included in your kit. Use a torque wrench to avoid over-tightening, which can crack the supercharger housing.

4. Reinstall the Intake Manifold

The intake manifold included in the Hennessey kit is designed specifically for their supercharger setup. Place the intake manifold gasket on top of the supercharger, then lower the manifold onto the studs or bolt holes. Tighten the bolts in a crisscross pattern to 10 Nm (7.4 ft-lbs) incrementally. Do not fully torque one bolt at a time.

5. Reconnect the Throttle Body and Intake Ducts

Bolt the throttle body back onto the intake manifold using new gaskets if supplied. Torque to 10 Nm. Reattach the intake ducts, ensuring all clamps are tightened. Check that the MAF sensor connector is plugged in securely.

Connecting the Cooling System

The Hennessey V8 supercharger uses an intercooling system integrated into the intake manifold. Proper coolant flow is critical for maintaining intake air temperatures.

1. Attach Coolant Lines

Locate the two coolant fittings on the supercharger – typically one inlet and one outlet. The kit includes silicone hoses with quick-connect or worm-gear clamps. Connect the hoses to the engine’s cooling system. On the F-Type, the factory coolant lines for the stock intercooler are reused. If your kit modifies the routing, follow Hennessey’s diagram precisely.

2. Fill the Cooling System

Use a 50/50 mix of Jaguar-approved coolant and distilled water. Pour coolant into the reservoir until it reaches the “max” line. Start the engine briefly (a few seconds) to begin circulation, then check the level and top off. Repeat this process until the level stabilizes.

3. Bleed the Cooling System

Air pockets can cause overheating. With the engine running and coolant cap off, let the engine reach operating temperature while monitoring the temperature gauge. Rev the engine to 2000–3000 rpm for 30 seconds to push air through. If you see bubbles in the coolant reservoir, that’s normal. Continue until no more bubbles appear, then cap the reservoir.

Finalizing the Installation

1. Reconnect the Battery

Reattach the negative battery terminal in the trunk. Tighten the clamp securely.

2. Refill Engine Oil

Add fresh engine oil through the filler cap. Use the viscosity and specification recommended for your F-Type (typically 5W-30 full synthetic). The supercharger kit does not require special oil, but Hennessey recommends a high-quality synthetic. Crank the engine without starting (by pressing the gas pedal to the floor) for 5-10 seconds to lubricate the supercharger bearings, then start the engine.

3. Check for Leaks and Noises

Let the engine idle for 5–10 minutes. Inspect all coolant hoses, vacuum lines, and bolts for leaks. Listen for unusual whining or knocking. A slight whine from the supercharger is normal after installation, especially during acceleration. If you hear grinding or scraping, stop the engine immediately and check for interference.

Testing the Performance

1. Initial Drive

Take the F-Type on a short test drive in a safe area. Start with gentle acceleration to confirm the drivetrain behaves normally. Gradually increase throttle to build boost. The Hennessey kit typically adds 200+ horsepower, so the difference will be immediately noticeable.

2. Monitor Vital Signs

Keep an eye on the coolant temperature gauge and engine oil pressure. If the temperature rises above normal (around 220°F coolant temp on the factory gauge), something may be wrong with the cooling system. Also listen for pinging or detonation – if you hear it, you may need a tune (Hennessey often provides a calibration file for the ECU).

3. Diagostic Checks

Use a scan tool to check for any trouble codes. Common codes after a supercharger install include MAF sensor codes or vacuum leak codes – usually caused by loose connections. Re-check all connectors.

Maintenance Tips for Long-Term Reliability

  • Change oil every 5,000 miles with a high-quality synthetic. Forced induction increases engine stress, so shorter intervals protect the bearings.
  • Inspect supercharger fluid level (if the unit uses its own oil). The Hennessey kit uses engine oil; no separate fluid required.
  • Keep the air filter clean. The supercharger draws a lot of air; a dirty filter reduces performance and can cause lean conditions.
  • Check intercooler coolant level monthly. Low coolant can cause high intake air temperatures and power loss.
  • Listen for bearing noise. If the supercharger begins to whine excessively (different from the normal induction sound), have it inspected.
  • Use high-octane fuel (91 or 93 AKI). The higher compression ratio and boost require premium fuel to prevent knocking.

Conclusion

Installing the Hennessey V8 supercharger on your Jaguar F-Type is a demanding but deeply rewarding project. The power increase transforms the driving experience, making the car feel like a genuine supercar.
