Some much thinner wire such as 56/030 is more than up to it, 76p a metre from
vehiclewiringproducts.co.uk this is thinwall which will be much better with the heat of under bonnets also, this carries 39 amps continuously and is similar to what I've used, I used 2X 28/030.
If you use gold plated terminals on the wire this would be even better.

I'm sorry but for once you are wrong.
A 90 Amp alternator will do 80 Amp all day long and will peak at over 100 Amp. It will not deliver 100 Amp for a very long time but an hour won't be problem. I repair alternators and starters for a living so couldn't resist replying.
