Not all Land Rovers are useless!
I know this thread has been around for a long time and is where I got the idea to do the conversion on my HDJ80, being a mechanic it was a straightforward for me to do around eight or more years back, everything done to my 80 is in my build thread running for about 11 years now.

So to the alternator. As per @Photoman this is pretty much spot on, the larger alternator will 'see' the same load on the engine for normal day to day running, i.e. start up go to work or the mall and return home, the stock unit may ramp up to around thirty amps after starting from a cold night but will soon reduce this to as little as 10 or 15 which will again lower soon enough, in other words it is rarely going to be asked for the full 80 amps it can supply. The larger alternator comes into it's own when helping with winching or replenishing a battery which has been exposed to the lights having been left on for a couple or hours and even then it will only be at a high rate for a short time. There are other times when the higher output is desirable for example, my engine cooling fan has been removed and fitted with an electric one from a Mercedes, and if I had all the lights on and HRW, radio, wipers and was for example stuck in traffic, then this is when a larger alternator comes into it's own.
I think it is a great modification and well thought out all those years back, and I gather people are still doing the conversion today, as great as the 80 it is times move on, and upgrading with worthwhile mods is the way to go if you want to keep these great vehicles on the road.
