I am running on a 65x36 foot track.
No boost or turbo
LRP X12 17.5
4.65 fdr.
I started with the 2 dot stock timing for the motor. The car is fast with this and the motor is around 155. I was at a 4.53 and 5 boost and a 4.53 FDR and the temp was 195. This was in qual 2.
I found it very interesting that with 1 tooth down and removal of any boost I saw a drop in temp by 40 degrees. My fast lap was the same from qual 2 with the 4.53 to qual 3 with the 4.65. But my run was a total of 3 tenths better with 27 laps.
I did try backing the timing of the motor all the way to 4 dot and running a 5.5 fdr with 20 boost. This was not as fast by lap times but it did run the motor back up to 190.
I think I am close with my current settings and feel there may be another tenth to go on the laps.
I will also note I used the same battery and car setup in my testing. I know these are 2 variables that get over looked. One thing I think that is important is the battery pack. I have a few high end packs and there are differences by a couple of tenths. I think this will also affect the correct gearing for a given motor and track.

with my duo2 with the same setup it had more rpms but didnt have the punch,the redline is close to the same rpms but has a little more snap.this was done holding the car to hear the rps and a few test runs on the street
dodge what packs,i'm using smc 5200 24c

5.26FDR w/Jaco Blues
Motor timing @ N (which IIRC is 15degrees compared with other manufacturers)
Timing boost = max
Turbo boost = max
0.3second delay
Vegas 200
100x40 outer track dimensions, tight chicane leading into full length back straight followed by sweeper.
The infield is busy, keeping the car turning and transitioning. I set the gear ratio to keep the motor on boil throughout the infield. That 0.3sec delay doesn't hit until halfway down the back straight.

I also know of a fellow racer I pit next to. We are the fast guys with 17.5 at our track. He was using an SMC 6000 28C, then strapped in an SMC 5200 50C and went 2 tenths faster.
I also think that boost and turbo will add more heat to the motor than make it any faster if you have them set to high. I think that most people are using to much timing, mechanically or electronically for their given track size and battery.

Yes, this is very true! I had been running some Orion 3300 30c batterys and felt my car could of have been faster in all aspects of the track. I spent countless hours trying different gearing and hotwire setups. Purchased a new Flighpower 5000 40C pack and it was almost night and day.

Yeah, Novak says that N is 30 degrees, but supposedly their 30degrees is only 15degrees in a Duo. Not that somebody's angle-o-meter is busted 
but the guy who wrote the unofficial Tekin RS user manual explained this discrepancy. I said 15 so that anyone with a non-Novak motor could replicate my settings properly without melting their toy car into the track surface. IIRC means "if I remember correctly".
Yes. I've been all over the spectrum of gearing and timing with this Novak motor, and it's sensitive to the single tooth at these settings. That tells me the relationship between timing and gearing is appropriate. If a tooth or two didn't feel much different, that would be a sign the high timing was numbing things down.
