I run up there occasionally, nicest facility around.

I ran in the JC race 2 weeks ago, and had a blast.

They have a long straight, so I would definitely start with at least a 20 tooth and go up from there. I came off cooler up there than I do at home (even after going up 4 teeth) due to the long straight and higher speeds.

Just remember to check temps every 3 min.

edit: I'm also running a Proline Bulldog body with all of the vents cut out, and it won't get anywhere near 160 unless I push it for 10 min or more.

edit2: If you're going to be running upp there frequently, Wilder is the Associated guy to get to know up there. If the .2 is anything like the .1, you'll just throw it down and learn to drive it. The hardest part of 4WD is NOT overdriving the car. Come into the corners under control and power out accordingly. It's fun to throw it around, but you're not doing anything but wasting time.
