2006 MCS JCW overheating in autocross
 

Considering extra, "pusher" fan. Anyone have ideas, suggestions, solutions?
Thanks, JT:)

Try one of the wetter antifreeze additives and change/remove the Thermostat

Overheating
 

I'll see what I can do about the thermostat, also changed to 5-40 oil. Measured the fan room, that's not happening, read up on "water wetter," that's not going to happen either. Has anyone tried venting the hood?

I've been running it in my show car and the water wetter alone dropped my temp 25 degrees , swapping to a lower temp thermostat dropped me another 20 degrees.
I've also read that you can get different radiator caps to hold more pressure ect to change cooling capacity

the water wetter is a cheap thing to try same as the thermostat if you drop the idle temps by 45/50 that gives more headroom for the autocross thats a short burst of heat

possibly that and icing down the radiator between runs as well
