Need to source 120A alternator
Discussion
Can anyone please recommend a reliable make/source for a 120A alternator for my Chim 450.
The reason I need the uprated unit is that I have the Mk1 Imprezza PAS rack with an electric pump which can draw 70+ amps and the std 100A unit is not man enough, such that on the hottest day of the year, a week or so back, fried itself.
Many thanks....

Does the car have a heated front screen?
The theory runs the practice and Mr Maths is always correct
Engine - 20 Amps Continuous
Lights - 15 Amps Continuous
Blower - 5 Amps Continuous
Engine Cooling Fans x 2 @ 10 amps - 20 Amps Intermittent
100 Amp Output Alternator will cover a 60 AMP PAS current draw when engine cooling fans are off and a 40 Amp PAS current draw when engine cooling fans are on
Going by the above calculations, a 120 AMP alternator is not required

But 100 amp alt would not cover if the PAS pump draws 70+ amps (which my pump does), albeit intermittently. Also the high under-bonnet temps will have a mechanical (bearings etc) and resistance effect.
None of this takes into account the possibility that the 'fried' unit may well have been made of Chinese toffee.
I'm just going for belt and braces.

I bought one for my P38 diesel (same quality different part number) 3 years ago and have had no problems.
