Fiat 90-90 Turbo, repairing a steep logging road

Einar named this hill 'Valmetsklia', translates to 'the Valmet slip'n'slide'. It is the reason we got the Valmet forwarder, it's so steep that no other type of vehicle can get down with a trailer or any kind of load.

I'm just curious.... won't turbo make 90-90 much thirsty on diesel?? The 90-90 was originally naturally aspired and very easy on fuel

I don't know the answer to this... I didn't own it before, now I do. I fill the tank maybe every 2 months. In theory, there's a lot of theory, my dad who owned it before me and put the turbo on claimed it should use less fuel, but realized he would only run it harder because there was more power available. I think diesel burns at a rate related to oxygen, so more oxygen and fuel = more power produced = less hours spent for the same job? I really don't know how it all ends up, I just know this tractor was pretty gutless before turboing, now it pulls all the gears hard up any hill with almost any load, and it's just more fun and also time efficient to do any job with. I am sure the truth is somewhere in the middle here, you can do more work faster now, but of course that burns more fuel. If you prefer, you could go really slow and only fill the tank every 4 months. Turbo or not ?
