Since there was a 70 amp fuse on the Audi I assumed it was a 70 amp fan but it's a 500 watt fan so only 40+ amps. Turns out the fuse on the ground side was not a stock fuse. It's still extremely powerful and sufficient to cool the engine even on the 100F days I've been testing it. I don't think it's even run on high yet, but I also haven't climbed any hills.

Following the cooling system fixes it ran real strong yesterday. I'm still flushing the oxidation out and will continue to do so until I get clear water out.

I ran it up to 75 mph and could tell it's revving pretty high but still runs smooth and strong. I'm going to experiment with a tach from a spare Mk2 cluster and see if I can get it to work.
