The "turns" refers to the number of times the wire is wound around the core of the stator. Usually, higher turn motors use thinner gauge wire, so they carry less current. Lower turn motors use thicker gauge wire, and carry a lot more current.
I see,,, thanks for the info ..

I'm looking for a starting fdr for an 8.5 running touring carpet on a 40 x 80 track.

Thanks

Which SXX? The Stock Spec? If so...

4 dot, 4-6 (depending on the MK) on boost, 6.2-6.5 FDR.

Default X-12 10.5 WGT with 12.25mm 1s lipo rotor

im running WGT X-12 10.5 4 dot timing and 12.25 1s lipo rotor with a tekin rs speedo with no timing or boost. I have 88/33 gearing. car is ok speed but should i go down in pinion to get more torq? would that lower gear end up giving me more speed on the streight?

Weird things like that call for the process of elimination.
Assuming that your solder joints are ok and nothing is dragging in the driveline, and your speedo is setup right.... maybe check that over and redo the speedo setup to be sure.
Try another sensor wire. Try another motor, to make sure it is in fact the motor.
Then try replacing motor parts if you have spares: another sensor then another rotor, check the bearings. Hopefully some of that will be it. Otherwise it leaves only the motor windings which you can't do much about.

I'm running a 4.33 ratio with 1 dot (5 degree insert)
(Tekin Rs 208 no timing profile) on 100x50ish? track comes off at 165-170 every time with a heat sink and a fan (17.5 rubber TC)
I tried more gear but it seemed to get soft at 3-4 min and got near 200.

I'm running a 4.15 with the 2 dot insert (no advance, I believe) and the motor temps 165 deg with a fan/heatsink. The car is very good in the infield and pretty good on the straights although I'm going to experiment with more timing and shorter gearing.

Cheers,
Mike
