The perfect technological match  – Kenne Bell and the fabulous Ford 5.4 4V. Never have there been kits with so much HP potential and flexibility in choice and never has there been a Ford engine like the 5.4 4V. The Shelby 5.4 engineered cars are strong and durable because they were designed specifically for a supercharger. Best of all, the 5.4 4V has tremendous HP potential, given the Kenne Bell supercharger and inlet component upgrades.

WHY MORE HP WITH THE SAME BOOST/PULLEY?

We’ve published a lot of information on the Shelby, but the following HP examples will explain why we talk so much about inlet systems. If we’ve learned one thing Since 1991, it is KEEP INLET SYSTEM LOSSES TO A MINIMUM. Supercharger size, efficiency and even boost are secondary if the inlet system is undersized and cannot supply sufficient air flow to the supercharger. It acts as a restrictor plate. Like a 2bbl carburetor on a 500” engine. The supercharger must spin faster to make up for the inlet boost loss. It then uses MORE engine HP to make the same boost. Oops! Remember that inlet restrictions LOWER the atmospheric pressure into the supercharger – and the actual boost the engine therefore sees. It’s a lose-lose situation. This is why the Kenne Bell 168mm manifold, throttle body etc. are so important to the HP a supercharger develops. See FAQ’s Supercharger boost vs. inlet loss.

DO I NEED UPGRADES?

Our kits were designed to leave no one hanging and wishing they could step up the power with some quick simple supercharger bolt ons. Note that any one poor flowing component can limit the flow of the other inlet parts anywhere in the chain. The mammoth sized Kenne Bell Dual 75mm “Mammothfold” flows more air than even the big 75mm throttle body. It blows away the competition. The engine makes more power because the supercharger uses less engine HP with a cooler air discharge temp.

Note: 3.6, 4.2, 4.7LC fits under hood of Shelby Super Snake. Check for recommendations on stock hood Shelby GT500. New 4.2LC, 4.7LC kit clears firewall without sacrificing inlet air flow.

The Boost-A-Pump and/or the Flash Tune can be deleted from your order at time of your order review call with our Sales Specialist.
