2002 Ford Mustang GT AFM Power Packages - NIkki's Six - Two-Valve Buildup Part 3

With the KB 2.6 blower being a "tuner" application, items such as fuel injectors ultimately are selected based on the anticipated or desired amount of horsepower (based on engine size, pulley combination/boost, and so on). For Nikki's setup, Ford Racing Performance Parts 60-lb/hr injectors were chosen. With additional fuel-system-support components being installed, these squirters will be more than sufficient for up to 700 rear-wheel horses.

While AFM's N-22 4.6 camshafts are the hot ticket for naturally aspirated steam, its F-62 cams are the perfect profile for boosted Two-Valve applications. As such, a cam swap was performed before Nikki's new blower was set in place.

Fuel rails, injectors, thermostat housing, and a few additional incidental pieces are fitted on the intake manifold before installing the Kenne Bell blower. As we mentioned in past articles, Nikki is a hands-on Mustang enthusiast, who bolted on many of the parts that were evaluated in our three-part study.

Because of some nuances in joining the KB intake and Trick Flow heads, a minor amount of grinding and light filing is required in four areas-on the intake manifold, inner gasket surface, heads and intercooler-due to a clearance conflict between the coil bosses and the valve-cover rails.

Achieving proper fitment is a finesse-intensive task that requires patience, and a lot of time spent grinding and fitting the blower assembly on the engine. It's also crucial to note that all intake ports should be covered with tape to prevent foreign materials from falling into the engine.

With everything properly filed and clearanced, the Kenne Bell hardware is bolted down on Nikki's modular 5.0. A 3.25-inch blower pulley was selected for this effort, and should generate approximately 15 pounds of boost.

Adding the KB 2.6 on a Two-Valve New Edge 'Stang requires swapping the factory throttle cable with one from an OEM '03-'04 Cobra. The necessary part is included with the supercharger system, and it's replacement is straightforward.

Nikki hangs the new heat exchanger below her Pony's front bumper support.

Anderson's Power Pipe (PN AF-0117c), Abaco's DBX-97b digital mass-air meter (with air filter and Ford Lightning-60-lb/hr-injectors calibration) rounds out the air-inductive hard parts in an AFM/Kenne Bell 2.6 blower package for 4.6-liter Two-Valves. On the fuel side, although Nikki and her crew added the fuel pump from a Ford GT (see On the Dyno sidebar), a KB Boost-a-Pump also was added to the fuel system to help ensure fuel-volume is sufficient enough for making big steam.

The combination of an '03-'04 Cobra air inlet and top-mounted IAC valve present an overall height for the supercharger assembly that mandates performing delicate surgery on a New Edge's factory hood (if using an aftermarket bonnet is not your fancy).

A pneumatic cut-off wheel or sheet-metal nibblers are the best tools to use for this segment of the project, as is a lot of patience. When complete, and with the faux hoodscoop's grille in place, the Kenne Bell's whine is the only indicator that there's a lot more going on under the hood than one would imagine.

All done, and ready to rock the rollers of Anderson Ford Motorsport's Dynojet chassis dyno!
