Whipple W140AX 2.3L Supercharger – Competition Kit for Ford Lightning (1999–2000)

Unleash Extreme Power with the Whipple W140AX Supercharger Ford Lightning

If you’re craving more power from your 1999–2000 Ford Lightning or Harley-Davidson F-150, the Whipple W140AX Supercharger Ford Lightning is the upgrade you've been waiting for. Built for extreme performance, this system uses Whipple’s latest twin-screw technology, delivering industry-leading efficiency and size in a direct bolt-on package.

Whether you're sticking with the stock 5.4L engine or pushing the limits with a built setup, the W140AX is designed to outperform. With proper engine modifications, it can handle up to 25 PSI of boost, turning your truck into a street or strip monster.

Key Performance Advantages

Compared to the factory Eaton roots-style blower, the Whipple system offers:

• Drastically lower intake air temperatures
• Reduced parasitic horsepower loss
• Substantial gains in torque and overall horsepower

Even more impressive, it’s a true bolt-on system. That means you won’t need to cut the firewall, modify the hood, or struggle with throttle body fitment. In fact, it works perfectly with both stock and aftermarket throttle bodies.

What’s Included in the Competition Kit

To make your installation as simple as possible, Whipple includes everything you need right out of the box. This kit comes ready to run at 13 PSI and includes:

• 140ci axial-entry Whipple twin-screw supercharger
• Large-mouth inlet casting for improved airflow
• High-flow cold air intake system
• Massive S&B True Flow 9” filter
• Oversized billet bypass valve
• Internally lubricated—no need to tap your oil pan
• All required hoses, brackets, and mounting hardware

As a result, your install will be clean, complete, and ready for action.

Boost Pulley Options

You can fine-tune your boost levels based on your goals:

With stock 7.5” crank pulley:

• 3” (11.5 PSI), 3” (13.5 PSI)
• 2.75” (15.5 PSI), 2.625” (17.5 PSI)

With 9” crank pulley:

• 3” (12.5 PSI), 2.875” (14.5 PSI)
• 2.75” (16.5 PSI), 2.625” (18.5 PSI)
• 2.5” (21 PSI), 2.375” (23 PSI)

Because of this flexibility, you can set your truck up for daily driving or max effort racing.

Why Choose Whipple?

There are plenty of options out there—but here’s why Whipple stands above the rest:

• No boost lag, unlike centrifugal superchargers or turbos
• Axial entry case increases efficiency by up to 10%
• Instant throttle response from idle to redline
• Race-proven design that’s also street-friendly

In other words, Whipple gives you big power with everyday reliability.
