For those of you that might be interested...I chose to "stick" with the stick packs (too many packs invested) and wanted to do the "BK fan MOD". I mounted up two 25mm fans. I am running 16T pinion with a 60T V2 center diff. Pretty tall gearing, but after a ten minute Main my ESC/MOTOR temps were 135/165 with an ambient temp of 95 degrees out. So I am pretty happy with the fans. I had to chop off the rear Exotek chassis piece, Mod the rear bottom chassis piece, Mod the rear top chassis piece, and Mod the RX box to allow the fans sufficient space behind them. Here are some pics:

Im with the higher gearing thing, Correct me if I'm wrong here, If you drop to a 60 Spur and step up to a 14 pinion the ratio remains the same ?, but if you only step up to a 13 pinion it then changes the ratio and the way the truck pulls off the bottom and middle??
Craig,WC, you guys want to chime in here?

A lot of guys here will tell you to try a smaller pinion, add boost , timing, ect to improve the trucks acceleration.
Instead if you need more acceleration ?
Gear up a tooth ..
Whats happens when you gear down a tooth ?
Just risks more wheel spin and this can kill the
acceleration your looking for ....
However
If the traction is good a smaller pinion is smoother & coast brake improves ....
( better for infield performance)
Suggest to always test a smaller & larger pinion just to see if there is a benefit with either...
Using the Reedy Sonic 550 4.5 *
( 32p/62 spur , 12t <> 13T pinion)
*Hauls azz fast
