Even with the dyno fan, it is very difficult to replicate real-world airflow.
Your bigger pulley is already straining the limits of the OEM heat exchanger....time for bigger.
The car is definitely pulling some timing and dumping fuel top-end.....how much? Only datalogging will tell.
A bigger HE + a bit of tweaking to your tune should net great results, IMO.
If it's the heat, it must have built up fast. Because I had my I/C pump running the whole time and before each pull I looked at the I/C coolant gauge and it was in the 80's.
Although I was very disappointed with the results of the run, I got an A+ on the looks of the car. At the shop everybody had to come look at it, a couple of the guy's just couldn't believe it had an AMG engine in it. And on the way down there traffic in one of the towns I went through got stopped for a line of cars for a funeral. I wasn't looking at the cars going by me much, but when I did look everybody was looking at my car. I got one "sweet" three "wows" and countless jaw drops
