We recommend converting to an electronic ignition on a musclecar engine over a point-type ignition system for several reasons. Also, HEIs allow full alternator voltage to go through the ignition system, which with our 50,000-volt coil allows larger plug gaps for better combustion and more power.
Is a HEI distributor better?
An HEI distributor is a great piece of equipment for an over-the-road car because it is completely self-contained. But without an external coil, a stock HEI cannot provide a strong spark at rpm levels commonly seen on the racetrack. Engines with higher compression or more horsepower also require a hotter spark.
How do I know if my HEI distributor is bad?
Bad HEI ignition distributors give off some warning signs that can be diagnosed by the vehicle owner.Engine Fails to Start. Plug Wire Engine Miss. Reduced Fuel Economy. Weak Spark. Electrical Arc and Shorts. Hard Starting. Smog Check Failure.
What can an HEI system cause?
The HEI system produces a more powerful spark, which allows for a wider spark plug gap for surer ignition of a fuel/air mix that may not be optimal. The HEI setup has also become a popular swap into non-GM vehicles.
How many amps does HEI draw?
Actually, an HEI draws only 2- to 3-amps, compared to the approximate 6-amps an external oil-filled coil draws. The lower amperage draw results in a much cooler running HEI coil.
What is an advantage of having an electronic ignition system?
Advantages of Electronic Ignition System: It has fewer moving parts. Low maintenance required. Less emission generates. Efficiency is good.
The function of an electronic ignition system is remaining the same as it produces a high voltage spark to the spark plug so that the fuel-air mixture can be burn or ignite. Because sensors are used in the system, it improves reliability and mileage and decreases emission.
What are the signs of a bad ignition control module?
Signs of a Bad Ignition ModuleAcceleration Issues. The vehicle may shake, vibrate or jerk when the gas pedal is pressed. There may be hesitation or lack of power during increases in speed.Temperature Problems. A faulty ignition module can cause a vehicle to overheat. No Power. The engine may turn over without starting.
How do I know if I have a bad HEI coil?
Bad HEI ignition distributors give off some warning signs that can be diagnosed by the vehicle owner.Engine Fails to Start. Plug Wire Engine Miss. Reduced Fuel Economy. Weak Spark. Electrical Arc and Shorts. Hard Starting. Smog Check Failure.
What does HEI stand for?
High energy ignition High energy ignition, also known as H.E.I., is an electronic ignition system designed by the Delco-Remy Division of General Motors.
How many volts is a stock HEI distributor?
12 volts An HEI should have a 10 guage wire run to it. If its hooked to stock wiring it may not be getting a full 12 volts. Many cars had ballast resistors or resistor wire running to the stock coil. A GM HEI should run on as low as 9 volts but 12-14.5 is required for good performance.
