Think I might have found my dream alternator gents and bulletproof too they reckon :-)!

215amps with 121amps at idle.

It is bulky but measured it up this morning and in theory should just fit drivers side behind the power steering reservoir with a 200mm supported extension shaft to pickup the existing Mitsubishi alternator V belt inline. 121amps at idle should power the 6hp Warn/Mahle motor no sweat :-)

As a point of interest I'd be a tad suprised if you get max output from that Alt with only one drive belt as well.

Anything over about 110/120 will usually have two belts.
That Alt of yours will pull something towards 2 horsepower at max output

Very good call too ET mate! The V belt does carry on a wee bit when hot :-(

Fired the old twactor up again colder just now, pulling 14.4v :-) ET might well again be on the money!! These damn V belts have next to no tension means bar a crappy idler of 10mm say.

Sitting in the cold beast now reved up a good 14.8v + :-) Damn ‘new’ belt I believe now is getting hot and expanding/not spinning the beasty Alt :-) No wonder it hauls the winch so well in the snow boys, lol :-)
Thank you All greatly!!!!

If its stretching when hot you should smell it, hear it and see the rubber discoloured on the drive surfaces, most likely polished finish - is this what you have? If so the belt is cactus. If you are struggling with belt tension, go down one size belt if you can to get the most out of the tensioner. I get my belts from Total Tools and they have a huge selection, but Bursons should also have a good stockholding. I don't know if you have the opportunity to go a double Vee drive on your setup? If so, this will help for sure.

I believe so now thanks mate, remember I mentioned up on Dingo Hill Track a short lived burning smell that I thought was my clutch. It is a relatively new ‘Gates’ belt from ‘Bursons’ and was the smallest I could possibly fit over the idler when new/cold. There may be a way to utilise its twin pulley with an extra off the water pump pulley somehow, will check it out tonight after work, Cheers!

I'm surprised some one doesn't use one of these

Great link

Jeez they have some nice doodads, twin and triple rectifier kits and enough amperage on some of their Alts to classify a Trol as mobile Genset not a 4X.

I see they sell a cooling kit as well.
A 2 inch 12V axial fan and 2 inch tubing, wouldn't be hard to dodgy something like that up I spose.

I have already sent this link to MB for his info. I will be buying 2 off the 400 amp units for fitment to my 100amp and 200amp alternators next month.

I sourced a 3" bilge pump fan from Whitworth marine to cool the alternators, works a treat, but generally only use it when statioary for an extended period, temps and charging seems ok with vehicle moving

Cheers Blokes! Phil if you could kindly order for me too next month would be greatly appreciated mate, maybe postage save together?
I’ve sussed out a possible Alt twin V belt option tonight by installing a larger belt to share across with the PS pump and off the crank together. It will require an additional idler pully for guidance away from others though, for now all I could do was to stretch the last bit of life out of the belt.
Installed the unpainted new bonnet from Blitz before doing another identical hill test run flogging it again with the boat.
Alternator sits perfectly in fresh air flow now.

Seems to have worked for now on the Alt although time will tell without the secondary belt yet and a rectifier thingybob.
Best news for the new bonnet has been water temps ran 3-5 degrees cooler on the big flogging haul up compared to last night and temps dropped about 3 degrees below TS presets when cruising on the flat, very happy, will test some more for sure!

Good result MB. I will order 3 x 400amp units next month.
