Choosing a bigger alternator (or 2)

Has anyone experience of fitting an uprated alternator to the 1.6 HDi 16 engine? Bigger than the 150A one in the parts list, I mean.

I'm trying to work out how to choose a likely replacement.

We're aiming to spend a lot of time parked, which means a larger battery and higher charging current.

The other reason to oversize the alternator is because it turns out that high charging current at low revs is a good way to shorten an alternator's life*--if I run the engine at fast idle, I'm hoping to keep the alternator well below its max output.

*the alternator cooling fan shifts almost no air at idle speed, and in a hot engine compartment, a larger battery will take max output for a longer time.

Re: Choosing a bigger alternator (or 2)

What size of battery and how much current are you looking to charge at.
Are you looking at a dc-dc charger?
