2004 Ford F-150 - More for Your 5.4

The elbow going into the blower is a polished, cast-aluminum piece. Now we'll attach the bypass-valve setup.

Remove the stock MAF sensor electronics. They will be installed in a larger MAF sensor housing from Vortech.

Attach the MAF Sensor and the rest of the inlet system.

Here is the supercharger system almost completely installed. The only thing left is to put on a new air-filter cover.

The air-filter cover adds a finished look to the system. However, we made dyno pulls with and without the cover with no difference in power.

A high-performance tune-up from Vortech Superchargers is uploaded into the computer system by way of a DiabloSport Predator hand-held tuning device, which is included in the kit.

A minimum number of parts were discarded in this installation.

Rear-wheel horsepower jumped from 216.6 up to 325.4, and rear wheel torque increased from 268.7 lb-ft to a much more respectable 373.4. All runs and back-up runs showed the blower was producing 9 psi of manifold pressure. The extra power should help the heavy-weight F-150 deal with the competition.
