Out of the box, the FAST XDi distributor is easily married to the FAST EFI harness using a single pre-installed Weather Pack connector. The CNC-machined and roller bearing-equipped housing is constructed from high-quality 6061-T6 billet aluminum. The distributor gear was swapped for a COMP Cams melonized distributor gear that is far more durable than the old bronze gears once required to mate to roller cams.
We mounted the E6 ignition module on the side of the Camaro’s transmission tunnel. The two adjustable rev-limiter dials are now easily accessible near the driver. Each rev-limiter can be adjusted in 100 rpm increments between 900 and 9,900 rpm.
The instructions feature multiple options applying the E6 to points, computer-controlled, HEI, and magnetic trigger system hookups. We are incorporating the FAST E92 coil and their XDi Dual-Sync Distributor. Wiring is straightforward with major 12-volt feed and ground, ignition switch, and a rev-limiter circuit for the starting line
limiter.
A timing retard input is also available that can be controlled by a separate FAST TRC-2 Timing Retard Control. This controller can offer significant benefits for nitrous oxide, boosted, and even towing applications. It can be set to operate as a nitrous retard control that activates when the nitrous is in use. In supercharged and turbo applications, the TRC-2 can be connected to a MAP sensor allowing you to retard 0-4 degrees per pound of boost with a maximum of 20-degrees.
We mounted the FAST E92 E-Core ignition coil directly in the front of our mounting panel. The coil is computer-designed with robust gauge windings to mate to the E6 CD ignition. The coil wire travels to a firewall feed through posts where we custom fabricated another coil wire to connect to our distributor.
The XDi Dual-Sync Distributor is a plug-and-play unit that can easily be married to EFI systems such as FAST’s EZ EFI 2.0. Setup is easier than some comparable brands as the distributor features reluctors and pickups that are correctly aligned right out of the box. This saves tons of effort when it comes to rotor phasing. Durability is another feature for the XDi distributor since it is constructed with a ball bearing guide within the 6061-T6 aluminum housing. A single Weather Pack connector can be readily married to the Camaro’s EFI controller to gain input from the Hall-effect pickups and to trigger both the ignition circuit as well as the cam sync signal.The XDi distributor comes out of the box with a cast-iron drive gear for typical hydraulic and solid lifter cams. With our 482-inch big-block sporting a
COMP Cams roller cam, we chose to go with another cool distributor gear option. The melonized distributor gear is made of steel and uses a melonized heat treatment process that gives the gear a very finished surface. This makes it compatible with any cam ranging from cast iron, ductile iron, and the billet steel used in our roller cam. With the comparative strength to a soft bronze gear, the new melonized gear is machined with more accuracy resulting in less spark scatter at the distributor.
