PRI 2012: MSD Performance’s New DynaForce Alternators And Starters

Along with a host of other great new products, MSD Performance unveiled their new DynaForce alternators and starters at the PRI Show, bringing to the table a full-featured lineup of new units designed for the street or the track in several color themes for your specific needs.

The DynaForce alternator line has been developed in both a street and race package. The high output “street” package comes in either a 120 or 160 amp version, featuring a designed that maximizes output beginning at idle and progressing through the high RPM’s, full baffle protection for safety, an easy-to-install side post, one-wire installation for 12 or 16 volt systems, and electronically balanced stator and dual plane rotor for high RPM reliability. MSD is offering these alternators in four flavors — chrome, natural, black, and satin — giving you some freedom in how your engine and accessories look.

The “race” alternators are engineered to deliver in extreme racing conditions, easily identifiable by their wrinkled red finish and one-wire installation. The 50 amp model is based on a common “Denso” housing, and accepts many aftermarket bracket assemblies for compatibility with many different applications. The 100 amp model, in addition to race-ready 12 and 16 volt charging system, sports an easy-to-adjust regulator inside that allows you to set it for your application — be it 12 or 16 volts. The mounting points are common to aftermarket GM brackets.

MSD’s DynaForce starters are designed to crank “the highest compression engine on a hot day in Death Valley,” according to their product release. A 3.4 horsepower motor spins the reduction gears with 4.4:1 ratio, delivering some really impressive torque capable of spinning an 18:1 compression motor. The DynaForce starters features a billet aluminum mount that’s easily clockable, a downsized design to assist in clearance issues, and a ball bearing supported armature and pinion gear.

The DynaForce starters are available for all of the common engines models and flywheel tooth combinations, including Ford, Chevy, Pontiac, Chrysler, Jeep, and AMC.

A Dynaforce High Speed starter is also offered, designed for race engines with magnetos that require more demanding cranking speed. These starters exhibit 25% more speed than the standard DynaForce starter, thanks to their 3.73:1 gear reduction, ensuring they’ll start even the toughest of engines and with great reliability and durability.
