Choosing the best alternator for your application is a lot like picking the right camshaft—not only does it need to support the power goals (electrical draw) that you’re planning for, it has to do it at the RPM range you’re using.

And that’s particularly true for a street vehicle that’s going to see plenty of idle and low-RPM driving and, at the same time, be supplying a lot of electrical accessories—like electric fans, a stereo, A/C unit, headlights, etc.

That’s why the folks from Powermaster come to the plate with a range of stout alternators that supply gobs of current (amperage) at low engine speeds. And better still, they’re able to cram all that performance into a relatively compact package too.

Powermaster calls them its Small Frame HPR Series Alternators, and if you’re looking for an ideal electrical power solution for your hot street car, there’s a good chance you’ll find it in the HPR Series.

To hear about them firsthand, the Summit Racing folks stopped by the Powermaster booth at the 2024 SEMA Show. Check out the video below to learn more, then click here to see every alternator Powermaster offers at Summit Racing.
