Overview
In a custom build where the charging system is planned from the ground up, this Powermaster Denso race alternator is the type of part the description addresses. It is a black one-wire unit with a high amp rating.
Powermaster spends its description on how output follows a curve, and why the pulley supplied with the alternator is matched to it. The listing names the Superlift brand and gives only package data, so size and mounting details are missing.
Who it's for
A builder assembling a custom car who understands pulley ratios and idle output can use the guidance in the description. A family car owner just replacing an alternator should match the original instead.
Pros and cons
- High amp rating
- Pulley guidance in description
- Mounting details not listed
- Alternator dimensions missing
- Brand row reads Superlift
- Output at idle not given
Performance notes
Output is not linear with speed and follows a curve unique to each alternator, so small speed changes at idle make a large difference. The description says high amp units can lose output under a low rotor speed and recommends the supplied pulley set.
