    Haven't seen a build blog quite like this yet... so here is the "Complete How-To Supercharge the 4.0L". If anyone is interested in supercharging a 05-10 4.0L V6... this blog is for you.

    This was a pretty simple build that I was able to achieve in about a full day's work (and achieved around +100hp). The cost of the Moddbox ran about $2200 and you can find it on ebay. I needed some injectors and tune after and was good to go :)

    You can find the dyno sheet here: 05 Mustang 4.oL V6 w/ Moddbox Kit-Dyno Sheet
    (Moddbox Install Kit, 47lb Ford Racing Injectors, #6NGK plugs, & a Salvage 94 T-Bird Supercharger)

    Ok... here it goes:

    COMPLETE HOW TO: Supercharge 4.OL V6 SOHC - Mustang 05-10

    The following Installation Instructions apply to the 2005-2010 Ford Explorer Mustang 4.0L SOHC models.

    You should read the entire instruction manual prior to proceeding with your installation.

    It is important to familiarize yourself with the ModdBox Supercharger Kit installation. It is the responsibility of the installer to properly install the Supercharger Kit. To ensure safety and proper installation, ModdBox recommends that this product only be installed by a qualified professional with access to pneumatic tools and a strong familiarity with automotive service procedures.

    91 or higher octane gasoline is required at all times.

    You must use fuel of 91 octane or higher. If your vehicle is not currently running 91 or higher octane, you must run your vehicle till empty and refill with the required octane at least 2 times prior to installation.

    Any previously installed aftermarket tuning equipment must be removed and the vehicle returned to an as stock condition before installing the supercharger.

    Any equipment that directly modifies the fuel mixture or ignition timing of the engine can cause severe engine damage if used in conjunction with the ModdBox Supercharger Kit. This includes, but is not limited to ignition boxes, air/fuel controllers, OBDII programmers, and any other device that modifies signals to and/or from the ECU. Aftermarket bolt-on equipment such as underdrive pulleys may conflict with the operation of the supercharger and must be removed prior to installation. Use of any of these products with the ModdBox Supercharger Kit could result in severe engine damage.
