What is a capacitive discharge (CD) ignition box?

A capacitive discharge ignition box stores energy in a capacitor and then rapidly discharges it through the ignition coil. This results in a much hotter and shorter duration spark compared to older inductive systems, leading to more complete combustion and improved performance, especially at higher RPMs.

What is the purpose of the dual rev limiter?

The dual rev limiter allows you to set two different maximum engine speeds. This is useful for applications like drag racing, where you might want one limit for staging and another, higher limit for the actual run, or for different driving modes.

Can this kit be used on a stock street vehicle?

While this kit is universal, it is primarily designed for high-performance, boosted, or nitrous-fed race engines. It requires custom wiring and a good understanding of ignition systems for proper installation and operation. It is not a direct replacement for a stock street vehicle's ignition system.

Product Details

If you're building a high-compression, boosted, or nitrous-fed engine for the track, getting the ignition timing dialed in is critical. This kit from FAST includes their E7 CD ignition box and an E93 ignition coil, designed to work together to take the guesswork out of selecting the right components for serious performance applications. The E7 CD box is a popular choice for race cars because it offers precise control over your ignition timing and rev limit, ensuring your engine operates at its peak without exceeding safe limits.

The E7 CD ignition box utilizes capacitive discharge technology, which means it delivers a strong, consistent spark even at high RPMs and under demanding conditions. This improved spark energy helps ensure complete combustion, which is vital for maximizing power and efficiency in high-performance engines. Paired with the included E93 ignition coil, this kit is well-suited to handle the higher energy demands of boosted and nitrous applications. The E93 coil is known for its robust construction and ability to produce a hot spark necessary for these types of engines.

This kit is a universal fit, meaning it's designed to be adaptable to a wide range of custom builds and race vehicles. While it's a universal component, proper installation will require understanding your vehicle's specific wiring and ignition system. Because this kit is not CARB approved, it cannot be shipped to California. If you're looking for a complete ignition solution for a high-performance or race engine, this FAST kit offers a well-regarded combination of a powerful CD ignition box and a capable ignition coil.
