Dynaspark - The last distributor you'll ever have to buy

Each distributor is hand-assembled by trained technicians with all-new components. No expense is spared in the construction of each Dynaspark distributor. Each distributor is equipped with a billet aluminum housing; the cap is o-ring sealed to the housing and then sealed with specific self-leveling silicon to ensure an airtight seal.

Before the inception of the Dynaspark, LTX owners have been riddled with the many failures of the OEM design. We have compiled a small list of a few of the major shortcomings of the Optispark.

Bearing
Rotor
Seals & Venting
Wiring Harness
EMI Shield

Bearing

The bearing on an OEM Optispark rests against the housing with no lateral support. The bearing is held in place by a high carbon steel retention plate that is fastened on opposing sides which only provides 40% bearing retention.

The Dynaspark is fitted with a press fit location for our sealed ball bearing which is rated to 13,000 RPM. The bearing is held in place by a 360 degree proprietary retention ring.

Rotor

The OEM rotor is designed with cost in mind rather than performance. The rotor contact is held in place by plastic rivets which tend to fail if brought above 6000 RPM. When the plastic rivets let loose, the rotor is no longer balanced and will tear itself apart inside the distributor likely ruining other components in the process.

The Dynaspark rotor is equipped with aluminum rivets to hold the rotor contact in place and balanced to 6800 RPM.

Seals & Venting

The most common issue found with the OEM unit is that the seals are insufficient. This causes venting to be drawn from portions of the distributor that do not allow for peak performance. Venting has three major benefits: Clearing moisture, clearing corrosive gasses created by inherent spark, and cooling the optical trigger. The defective seals on the distributor allow for the moisture and corrosive gasses to dissipate, however, the vacuum draws venting from improper sources which causes a stagnant air around the optical sensor keeping it from being properly cooled.

The Dynaspark is triple sealed allowing for the vacuum system to perform its intended function. The housing and insulator ring are designed for the primary and secondary venting, or what we like to call "cross venting." The primary venting cools the optical sensor, the secondary venting clears moisture and corrosive gases.

Wiring Harness

The OEM wiring harness location plays a major part in the design flaw. The harness is located on the top of the distributor where dirt and moisture collect. This is essentially a pathway for dirt and moisture leading directly to the optical trigger. The optical trigger cannot be salvaged after it has been compromised with a foreign substance.

We took great care in ensuring that our wiring harness is sealed. We designed an integral wiring harness that is virtually impenetrable. Our distributor will remain dry inside and perform its intended function while fully submerged underwater as long as the vacuum harnesses are kept above water.

EMI Shield

EMI (Electro Magnetic Interference) is a naturally occurring phenomenon when the electromagnetic field of one device disrupts or degrades the electromagnetic field of another device by being in close proximity with each other. In the case of the Opti-spark it would be the rotor and optical trigger. EMI is overcome by separating two electrical components with a conductive barrier which is in turn grounded out to a source. The OEM Optispark is equipped with an EMI Shield which is essentially a stamped sheet of tin placed between the optical trigger and rotor. Tin is a ferrous metal, meaning it contains iron. Iron attracts moisture, which in turn oxidizes the tin creating rust inside the distributor. This is a huge issue with the design of the Optispark and is one of the main reasons for distributor failure on most LTX motors.
