Porsche 911 High Output 150A Alternator

Porsche 911 High Output 150A Alternator

NOW AVAILABLE - LIMITED STOCK!

This is Classic Retrofit's upgraded high-output alternator for classic Porsche 911s.  

Tested at over 145A amps on the standard 911 pulley and belt and with a simple installation process, this UK-manufactured upgrade is the highest output alternator available for your classic Porsche 911.  The idle output is in excess of 75A!

This is a brand new unit, not reconditioned and there is no core charge or exchange.  Based on the Denso 6 phase 'hairpin' alternator, the casing has been custom designed to fit all 911 fan housing from 1965 to 1989.  The alternator offers superior efficiency and produces less heat than the original units.

This is not a 'rewound' Bosch or Valeo unit.
