A great way to get all of the power that you can out of your Ford crate engine is with MSD ignition kits. These ignition kits have everything that you need for your engine to reach its full potential--an easy-to-install, ready-to-run distributor featuring a high-output module that produces a vigorous jolt across the plug gap, a Blaster SS coil that's small but mighty and features efficient E-core windings, brass terminals and Rynite housing, and 8.5mm spark plug wires with separators--"the" performance wires for incredibly low resistance without electronic interference. Ford crate engine ignition kits also include a billet hold-down clamp, and a steel gear is installed on the distributor for compatibility with hydraulic roller camshafts. Power up your Ford crate engine with MSD ignition kits.

MSD Pro 600 CDI ignition boxes are 8-channel capacitive discharge ignitions designed for high cylinder pressure, high-horsepower engines running coil-near-plug ignition. When you're making extreme cylinder pressure with boost or nitrous on an inductive coil-per-plug ignition, lack of spark energy means you're leaving horsepower on the table. To answer this need, the ignition experts at MSD developed the PRO 600 CDI to provide unrivaled spark energy and dependability. Pro Mod to Pro Street, or yanking a sled in the dirt with a pulling truck, if you need to light 8 coils without fail, MSD PRO 600 boxes are the answer. Features include: * Eight outputs of up to 680 mJ of energy * All necessary wiring harnesses included * Continuous 600 mJ operation, without risk of failure from overheating * High-efficiency Alternating Current (AC) power delivery means less voltage draw from your battery or charging system * Over 50 kilovolts output voltage when used with MSD suggested coils * Spark duration of greater than 300 microseconds * 6 volts minimum required for starting and running * 12 volts minimum required for 600 mJ opereation * Maximum operating voltage 22 V * Direct plug-in to Holley EFI systems * Compatible with most EFI systems, including 5 V or 12 V drivers * Plug-in interface with MSD Power-Grid, Davis Profiler, and OEM LS-style coil harness * Reverse battery protection * Protection against shorted or open coils, and over temperature * Diagnostic LEDs help troubleshoot issues should they arise * On-the-fly power output selection wire, selectable between low power and high power operation * Fits most coil-per-plug engines up to eight cylinders (including 4- and 6-cylinders) * Additional CAN based features, when used with Holley EFI * Approved for NHRA Pro Mod Class

DIS-4 Plus HO digital ignitions are higher-output versions of the DIS ignition controls from MSD. They're designed for full race engines running high boost pressures from turbos, blowers, or nitrous. Their increased output will light up fuel mixtures even under these extreme cylinder pressures. Your late model distributorless ignition system will never be the same! The capacitive discharge ignitions feature multi-channel capability, complemented with multiple sparks, two rev limiters, and a timing control. These DIS ignitions are engineered with the latest in digital science, including power MOSFET technology and efficient IGBT coil drivers. They're managed by a 15 MHz micro-controller for extremely fast compensations and decisions. In the end, this creates incredibly accurate spark delivery, rev limiting, and timing functions. Throttle response and mid-range pull are also improved, due to a series of powerful multiple sparks that last for 20 degrees of crankshaft rotation. There is a two-step rev limiter, which gives you one limit to set for holeshots and another for top-end performance. For engines using nitrous or extremely high cylinder pressures, you can also program a high-speed retard after the engine hits total timing. Both of these features are easy to adjust with the new built-in rotary dials. They also feature an ignition interrupt that will prevent the engine from starting by disabling the output to the coil, a retard feature that retards the timing at the top end to prevent detonation, and an LED monitor that will alert you of a low supply of voltage or faulty input signals. Also, there is now a true step retard that can be activated through your nitrous solenoid wiring! The DIS-4 HO Plus digital ignitions are designed for 6 or 8-cylinder engines with three or four coil packs.

Racepak IQ3 data recorders represent an entirely new concept in data logging dashes. By placing the 32-channel data logger, 512 MB memory card, GPS board, and 3-axis G-meter inside the dash, every feature of the data system is now located in one central location. This means that only one small cable will transmit the data from all the sensors to the rear of the dash. This eliminates the need for a sensor harness, greatly reducing installation time, complexity and overall weight. The programmable shift lights are protected from sunlight by a molded shield above the lights, while the low-glare LCD display is well recessed in the housing to provide viewing in all light conditions. The rear of the dash contains the connectors for the external GPS antenna and V-Net sensor cable—plus the power, ground, and engine rpm external programming button harnesses. All data is stored in a MicroSD memory card located in the front of the dash between the programmable shift lights. This design insures easy access to the memory card for data download.
