Yep, running on the street though you can probably go 14. But you have the 13 in hand so try that. If your temping at 140ish, you may want to order a 14.

the motor was cool on the 15 tooth the esc temp light came on for 150 over. ill try the 13 tooth out. it was fast on the 15 but esc ran hot.

Sounds like as prostreet said a bigger cap is your solution if the motors cool, esc's hot and going to a smaller pinion brought the esc temp down.
In the mean time, try the 13 and if all's still cool, a 14 then ultimately do the cap when you can.

that sounds right to me but I haven't tried that setup since i run the center diff.

If I'm not mistaken, pin goes through the slipper plate to the spur or something, not the shaft right? Been a long time since I've heard mention of it since most are using multi pad slippers or the C-Diff... and I never ran the pin mod so going off memory from months back
There is an option rear top shaft that locks front drive (I think front), but that doesn't use a pin. It's an AE part.

Pin mod locks the slipper for the front, to the shaft. That way the front and rear are slipping together.

What does the pin run through from the shaft? The spur?

Found it...

Yes, you can by the Associated option part from your LHS or favorite online retailer:

This replaces pt no 91092 and does the same as the old pin mod (before my time).

Just finished a shorty pack mod to make the 10 min mains here in NC



What ya think?

Well, just got back from race night. How about slick clay on a 45 degree night. Talk about no traction. Good news, the diff rebuild with 2 shims works and works well - very smooth. It seems I left out one of the inner rubber seals last rebuild.

Was a little more consistent tonight, not as many turtles but the ones that I did have came at exactly the wrong times, got to work on the driving.

Any thoughts on what to do with the fluid as the temp drops. We race outside and will be racing through the winter here in South Carolina.

Looks good but do you really need two shorty packs to make 10 minutes?

10 minutes is asking alot of Saddle packs for a "i'm sure i'll finish" feeling.

Alot of guys stuck with sticks for that reason.

I really dont get why u guys all have problems with 10min mains? I drive 17mins with my 5600mAh noname batteries for 30$ xD but you cant drive really fast on our track.
