High Performance Starters for Racing Engines

An automotive engine starter functions with two main components: the starter solenoid and the starter drive assembly. The starter solenoid (mounted either remotely or directly to the starter) controls when power is applied to the starter from the battery, as the main positive cable connects to it. The solenoid is activated with driver input using a signal via the ignition switch on the steering column or dash. When the solenoid receives this signal, it makes an internal connection, allowing battery power to reach the starter drive assembly. When the solenoid relays battery power to the drive, an electromagnet energizes, causing the starter drive gear to kick out of the starter nose area and spin the flywheel on the engine, causing it to turn over until the driver releases the ignition switch. This allows the spark plug to ignite the fuel and air mixture being pulled through the intake tract while the engine spins and allowing the engine to run. Often, high performance starters use gear-reduction systems, allowing them to spin higher compression race engines that cause a lot of resistance to turning with ease.

Depending on the manufacturer, build quality, and year, make, and model of vehicle, an engine starter lifespan can vary. Typically, for factory engines in late model vehicles, starters last between 100,000-150,000 miles (but can last even longer, sometimes the entire life of the vehicle). For performance and aftermarket starters, engine heat from exhaust headers is the biggest enemy to starter life as the heat causes the components within the starter to expand and bind, reducing service length and performance. To combat this, starter heat shields help to insulate the starter from heat and deflect radiating heat from hot exhaust and underhood temperatures.

There are many options to buy performance starters online, but only one clear destination. With over 60 years in the business, JEGS has been selling high performance starters for a long time, offers starters at competitive prices, and ships in-stock items fast, often the same day.
