With the n54 equipped with a JB4, there was an option to make the rad fan more (and I think higher speed). I've been keeping an eye out for something like this for the M3 but its never been mentioned. Maybe a Benvo question if its possible..
Oddly enough my coolant temps are great. The thermostat keeps them 196-197, sometimes peaking a little above 200 but the. Drops pretty quick to 196.

I have an ice tank, no ice, bilge pump


My lines do run on the frame rails near the headers, I wonder if that's heating things. I may reroute down the drive shaft tunnel

Just checking the P3 doesn't have to be calibrated for AIT does it?
I Don't think the line locations really matter. Mine are down the center tucked to the underside. It's the damn material of the manifold and the ice box. Plastic and carbon would be the best choice.
