Yeah its just a slow warm up, but once it gets there, its really tough to bring it back down. Takes mine a good 45 minutes or more of driving before it gets there, but its a lot of iron to cool down....once it is. I do run either water wetter or Antifreeze depending on the time of year. And if its cool outside, its not an issue...So I am right on the edge with my setup. Any improvement should show up immediately.

At the drags, Its actually difficult to get it to full temp. I actually only use one fan to save on battery power, and it never gets past 180....
