Everything cools well except at the 4000 rpm range. I am going to add a front center 996/997 radiator and see if that is an immediate fix. Steve at renegades is always a help even with my toy jet setup. I am going to run some inch and a quarter lines up front and mount it temporarily, running it in series. If that solves the cooling then I will add the radiator into my spoiler or my 935 spoiler. This will tell me if I have or don't have enough square inches on my radiator... After that is solved I can add a tall gear also.

Not a single person did the 4000 rpm challenge! 😞
