When it comes to the Performance part of the Performance Racing Industry show, Powermaster Performance holds up their end of the bargain. Racing enthusiasts always look forward to the newest release from the charging/starter experts at Powermaster. John Babcock and his crew of electrical wizards understand what racers are looking for and they routinely hit the target squarely in the bullseye. This year’s Mini Denso one-wire alternator represents compact charging at it’s very best.
According to the company’s vice-president of marketing, Denise Lawrence, “From idle to top end, this is the highest current in the lightest, smallest alternator.”
We’re used to big claims about new products at trade shows, after-all, it’s not our first rodeo. Looking closer at the data, we started to see that Denise might be correct. The power curve displayed at the counter showed an amazing 35-plus amps at idle with over 75 amps at high-idle. Those numbers are pretty stout for any alternator, then consider that the unit has a housing that weighs 6.5-pounds. That doesn’t include the mounting brackets, but those have little weight to begin with.
Denise, was in fact, correct. That is a lot of amperage in a very small package. Powermaster built the unit as a direct replacement for the 93mm Denso style alternators. They offer the new alternator in a natural finish with a V-belt pulley (#8173), polished finish with a V-belt pulley (#28163), or black without a pulley (#8163). The unit is a simple one-wire installation and is machined to mount for a direct fit and a solid ground path which is essential for the black finish version (#8163).
These Powermaster’s Denso units come with their unique voltage control system that is trademarked with their XS Volt brand. For circle track racers this is a digital control where the regulator responds in milliseconds as a true one-wire unit. Anaolog regulators tend to respond in seconds. The XS Volt system also allows the consumer to adjust the voltage, allowing for a set point between 13.5 to 18.5 volts, which makes it perfect for 12v, 14v, or 16v systems.
At under 7 pounds, and mountable practically anywhere on the engine, there’s no reason to ever run a complete loss system ever again. For more information on this or the other fine products in their lineup, please visit them online at Powermaseter Performance.
