When you’re trying to generate reliable horsepower, making sure there’s enough fire in the hole becomes a constant battle. That battle intensifies as the rpm range climbs to peak power generating ranges, so having a stout ignition becomes mission-critical. PerTronix has been developing ignition solutions for horsepower junkies for over 40 years and their new HEI III is the newest evolution that will help any engine with a distributor generate the power it needs.
The HEI III is the latest progression of the PerTronix Ignitor series technology they have been developing over the past four decades. These ignition products were introduced as a way to help make points maintenance in a distributor easier while increasing performance. By adding more spark, reducing misfires, and adding a digital rev limiter, the PerTronix Ignitor series became a godsend for those with muscle cars, hot rods, and performance machines.
Using the Ignitor series as a starting point, the HEI III brings the features of an ignition box right into a high-performance HEI module for any four-pin HEI distributor. According to Greg Raymond from PerTronix, the HEI III packs numerous features into a very tiny package.
“This new module features multiple sparks through the entire rpm range, plus an integrated high-resolution digital rev limiter. The rev limit settings are displayed with an LED feedback for precise rpm settings. The adaptive dwell maintains peak energy throughout the entire rpm range, reducing misfires while improving engine performance. With the HEI III, peak current level is reached just prior to spark for maximum energy without the heat build-up, increasing coil performance and module reliability. This unit also adjusts spark timing at higher rpm to compensate for the inherent electronic delay.”
The best part about the HEI III is that it will work with any engine equipped with your standard HEI-style distributor. Since the HEI III has the ability to provide increased energy with a lower heat build-up, it will work with any high-performance application. This makes the HEI III a great upgrade for any engine ignition system, including those that are taking advantage of a power-adder.
