Lightning 5.4L Supercharger Upgrade

The switch is on to the more efficient Kenne Bell Twin Screw supercharger. It's the most flexible and powerful product available for the 5.4 Lightning. Kenne Bell, The Innovators, designed a direct bolt on replacement for the factory Roots type supercharger.

The Twin Screw enjoys several key performance advantages over the Roots: Higher boost potential (up to 22 psi), lower parasitic losses (-14HP at 9.3 psi) and reduced air charge temperatures (-65° at 9.3 psi). And it's boost adjustable from 9.3-22 psi for any street or track combination.

Comparison dyno tests by Richard Holdener, technical editor for Truckin' and Muscle Mustangs & Fast Fords magazines clearly indicate the Kenne Bell BLOWZILLA Twin Screw produced a whopping 511 rear wheel HP vs 415HP for the Roots. Both were equipped with only a larger throttle body and big inlet system. With a Kenne Bell SWITCH CHIP® in the "POWER" position, and identical 9"x2¾ pulleys, the twin screw made 531HP. We felt that might be the limit for 100 octane unleaded, so we never flipped to the "SHOOT OUT" position of the SWITCH CHIP® with it's more aggressive spark timing. We slipped on a 2½" pulley and the mighty Lightning responded with 548HP and a pavement shredding 630 ft lbs of torque. A larger meter, extrude honed inlet and underdrive pullies can push power to 560+HP or 200HP more than stock.

Kenne Bell BLOWZILLA installed on the Lightning test truck. No less than a dozen sensors monitor a multitude of engine functions and components on every dyno run. HP was observed at boost levels of 9-22 psi.

• 160 HP increase on100% stock Lightning. Tuneable to +200HP with inlet and chip upgrades.
• *522HP/600 ft lbs with 590 ft lbs from 3300-4500 rpm at 21 psi w/only big filter & throttle body.
• Direct bolt on replacement for less efficient Roots style.
• 96 peak HP improvement over Roots style (511 vs 415) with 9"x2¾" pulleys.
• 60º lower air charge temp with direct bolt on replacement.
• 14HP less parasitic loss with stock boost. More at high boost levels.
• Boost range 9.7 - 22 psi vs. 9.7 - 14.7 Roots style.
• No boost drop off at any rpm regardless of boost (9.7 - 21.5 psi).
• Approx. 10HP per psi boost, easily adjusted with pullies.
• 3½" (9 psi), 3" (12.5 psi), 2¾" (14.5 psi), 2½" (16.5 psi) with stock 7½" crank pulley.
• 3½" (13.5 psi), 3" (18.0 psi), 2¾" (20.5 psi), 2½" (22.0 psi) with 9" crank pulley.
• Quick, easy one bolt/4 minute pulley changes vs. difficult to remove pressed on Roots style.
• Dyno tested and proven in back to back tests.
• Uses same belts as Roots style.
• All hardware and tuning instructions included in kit.

Kenne Bell was first to introduce a "dual program" Ford chip, the SWITCH CHIP®. It required 3 years and hundreds of dyno tests to optimize our Lightning Chips. We re-calibrate fuel, spark, load, torque converter, transmission, knock retard and sensors for two specific programs: 340-415HP and 415-580HP. This flexibility allows your engine to produce maximum HP for both the street and track. Just flip the switch from "POWER" to "SHOOT OUT." We have the optimum dyno proven calibrations for both.
