Default 10.5 (Sintered) Gearing in 1/10th TC

There's got to be a ton of information on gearing the 10.5 here and by searching in google but I've tried both and can't find it. Can anyone point me to relevant discussions? Thanks!

EDIT: We run on a small track, it's not flowing. A lot of coasting and accelerating, coasting and accelerating.

Sounds like a 34mm roll out to me.?
36mm is about the highest I've geared on a medium fast track.

With a Novak 10.5 Pro I was geared 7.20 FDR on rubber tires (thats a 27.5mm roll out) at MINNREG's last race and my car was stupid fast.

The track as 90x50 with a combo of tight low speed and very fast sections. Heat was not a problem and we probablt could have geared up more.

Marcos you mean to start at around 5.5 and then go lower if your temps allow or if its needed? I'll be running an Orion 10.5 BL and was told to run around 6.5 FDR...but I remembered you and others posting recommened FDR of 5.0- 5.5...which is pretty amazing...

Yep. Geared properly and in the right hands I believe the 10.5's are faster. Same for the 13.5's for that matter. Brushless is faster
