Thanks, that's about where I was thinking.

4.0 FDR is a reasonable starting point for a medium sized track. Lower for larger tracks.

Can timing...Crank it up, but check temps often, use a fan and make sure your drivetrain is as free as it can be.
the car is a TC6, track is about 100 x 40, so medium size and it's medium traction. I have a fan as well, and I just purchased some ceramic bearings so they will be going in as soon as I get them. I'm running a front ball diff (set tight) and a rear ball diff set loose. Tried a spool, but really didn't like the corner entry with it so went back to the ball diff.

I like running a 47/96 (4.08), last timing notch. Our track is around the same dimensions. Good bearings, good fan, and some light braking action puts me at 155*ish after a 6-minute run. This is the best setup for both TC6 and Serpent here (same internal).

When we run really tight layouts, I'll drop to a 46 and go heavy on the brakes (driving style)... temps still come off around 155.

thanks, I don't typically use much if any breaking at all
