Powermaster Alternator for Holley Mid Mount Accessory Drive

Level 7 Motorsports

Regular price $515.00

Over the past few years, we have grown to love the Holley Mid Mount Acessory drive kits.  However, there are issues with their alternator that cause it to fail prematurely.  Level 7 has worked with Powermaster to resolve these issues.  The alternator that comes from Holley suffers from two issues.  The primary issue is that the pulley ratio is off substantially and over spins the alternator.  The second issue is that they have an internal grounding problem and causes them to search for ground and will burn out the voltage regulator.  Our replacement alternator comes with an external grounding stud and can be grounded to the engine with a 10awg cable.  It also comes with a 3" pulley which slows the rpm down to correct the pulley ratio issue.  These alternators dyno at roughly 145-amp output at idle so there is no need to worry about output at idle. This is also a self-excited alternator so there is now no need to wire or connect the excitor connector.

We have been using these alternators for 3 years now without a single failure.  We even put them through the severe abuse of road racing in our yellow and white Squarebody for two seasons without issue.  That truck shifted at 7400rpm and would race at full load for 25-minute sessions.  So, rest assured that your alternator issues are the thing of the past.
