I would say there is a Setup 3, which is boost and turbo together. I have a .1 delay and a 2,500 start RPM so for the most part I am using both turbo and boost at the same time.
If your temps are 190 I think a few changes to your setup and gearing will bring you back down to the acceptable 170* range. Perhaps try a combination of setup 1 and setup2 to get the best of both worlds (the speed + the lower temps).

For setup3 what size track are you running on? are you running a lower (then 40) boost to make the two stack successfully? I am assuming your ramp is 1? what is end RPM?
if your end RPM is greater closer/over 10,000 then really its an linear variant of TB...
I found running the 0.1 delay laggy off the corners compared to 0 (or a BT setup) but temps seem to jump about 25F going from 0.1 to 0 delay.... maybe that is the compromise required to keep the temp from skyrocketing?
Is that the reason for using the 0.1 instead of 0?
thanks

Has anyone data logged the usable RPM range on a 1s 17.5?

yes, yes i have.

Hi,
track technical 25x8m high grip carpet. Spur 96, pinion 27, tires 58mm. At the moment settings are
Motor timing on five and half mark to +.
Drag Brake - 0
Reverse Strength - 33
Neutral Width - 8
Motor Type - BL-DL
Throttle Profile - 3
Voltage Cutoff - 2
Push Control - Off
Timing Boost - 30
Turbo Boost - 5
Turbo Delay - 0,2
Turbo Ramp - 2,0
Start RPM - 1598
End RPM - 11016
First problem that when in straight there is no feel of engaging Turbo Boost. And motor temps are ~55-60C. What suggestions? Something to change to get more speed and lower temps? Would like to lower temp a little bit because I am learning to drive and my speed is improving... so motor temperature will increase :-)

sure, what do you want to know? most of this is specific to the motor and the track.
to give you an idea, the slowest corner at the track that I race on, my motor is spinning about 2400rpm. but that changes from track to track and even varies a little based on tracktion. I have seen my lowest rpm range from 2400-3000 depending on the tracktion level.

How many motors and how many tracks have you tested? If it is not too much to ask, I'd like to know:
Size of track, high and low rpm to each track with each motor.

i would like to know what you used to do the data log on it. can it be done threw hotwire? or some other program

i have only run 2 layouts with the same motors. since I have a novak sentry, i have no reason to try different motors at different tracks or layouts. i have a duo 1 17.5 from eXpress Motorsports. this motor was purchase before vegas 2009. i would call our track a big track. my low rpm was around 1900 and the high was 11,800 on the back straight and 8836 in the infield. this is with a 91mm roll out and a 40mm rear tire. the track is about 100x40 and we run about 3/4 of an oval for the back straight.
to give you an idea. without turbo or timing, my baseline was a low of 2968 and a high of 12,875 on the back straight and on the infield 8,042
I am not sure how much value these numbers are because imho tekin setups now need to take into account too many variable to make a setup work everywhere. I can tell you that this setup really is setup for our track the day I ran it. this was after 3 round of looking at sentry data and adjusting start rpm, end rpm, turbo delay and gear ratio. this setup was basically optimized as much as I could for the track. I was able to put a full lap on my best times. I rarely find any change that I can do that with.

i really doubt that there is enough memory inside the tekin to store this much data. I am using a novak sentry. and i only log rpm and throttle position. by default the sentry also has x/y axis movement

that is good info yang. Thanks

I agree, I like my temp to stay below 150 during practice so it can run up to 165 or so when im beating on it in a race... for the time being I have been keeping with TB.... I tried going up and down about 5 pinions each way to try and find a sweet spot where the off temp was consistant without luck for BT.... any deviation from 6.0 seemed to amplify the problem... toasted a nemesis in the process... =/
For setup3 what size track are you running on? are you running a lower (then 40) boost to make the two stack successfully? I am assuming your ramp is 1? what is end RPM?
if your end RPM is greater closer/over 10,000 then really its an linear variant of TB...

I will say however the Nemesis motors like to be geared differently than Duo2's. So I am surprised you are also running a 6.0 final drive.
I have not tried 0 turbo delay either, simply because I do not have the head room on my temperatures to get away with it.
The tracks I run at are medium to large asphalt. I'd say about 140-150 x 70-80.

We can gear down and let the motor spool to 40k on the straight but it gets slower well before that. We can add gear until we only reach 25k on the straight and it gets slower. The magic is in between depending on the track.
