Hi, sorry about that slight over sight on my part, these have been updated now.

Eastbourne and Ipswich will follow this week, determined to try and get the Hobbywing motors going this fast as well but just don't get the track time

the track is a mix of fast straights and technical infield with a lap time of around 14secs, these are the settings I was using
211 firmware
MI4 CX
FDR 6.95 85spur 22 pinion
4: DRRS 6
9: Boost timing 40
10: turbo slope 12
12: Turbo Timing 18
13: Start RPM 6000
14: Turbo Delay 0.3 sec
15: Timing ACC 400
any suggestions to get the temps down?
Have been using the hobbywing 13.5 with these settings, it was not as quick but coming off the track after a 6min race at around 75-77 Degs

I would try lowering the start RPM as it is very high, I know the x12 is a revy motor but that still seems a little late. Also raise your FDR to 7.5 and let the motor rev out.

Hope it helps

have been told to let the torque of the motor pull it out of the corner, hence the higher start rpm, but will give your suggestions a try, thanks

Hi X12 buy design don't really have any torque due to the masses of internal timing in the motor, as with any changes you make always keep an eye on the temperature every couple of minutes to ensure nothing is going to go bang!

i would change fdr to 7.4 and lower boost timing to 30 take start rpm down to 5000 and acc up to 450 600 max

Hi, does anyone run a GM 13.5t with the supercharger software? If so could you please post your setup.
I seem to get a cooler motor when I run around 5fdr when most people run around 7fdr. I'm not far off the pace of the other cars(when I'm on the track)
but any advice with the GM motor would be greatly appreciated.
Thanks.

I have often run a GM 13.5 (the 2010 gun metal grey one) and find it quite similar to an SP V3, a bit more punchy but with hotter temps, anyway my starting setups on an outdoor track (uk outdoor track so we are talking 35-45 m straight) are as follows;

FDR - 6.2
Software - 211
DDRS - 7 (up this if temps are ok)
Timing - 48
Turbo - 16
Start RPM - 9000
Turbo Delay - 0.0
Timing ACC - 300

My advice would be to keep it smooth, only use full throttle if you have to, ie on the main straightaway, if you are unable to do this add 0.3 onto the turbo delay!!

Hi, i use :

FDR 8.0
DRRS 7
Start RPM 8000
Turbo delay 0.2
timing Acc 350

we have 70m straight and after 5 mins comes of at 85-95'C

how fast are you compared with others on the straight? As mentioned above, though x12 likes to rev at 8000 it seems to be late. Our track has approximately 50 m of long straight and using a higher rpm and fdr of 7.7, others managed to overtake at the straight.

However, in my case it is a bit different since I'm using the x12 10.5 T. What is the surrounding temperature during running this setup? Ours again approximately at 40-48 degrees celcius and my motor temp. was at 89-92 degree celcius.

Thanks,

ill take a note on that..today will not use 65c and see how it goes...

Actually, I disagree with that statement (no offence), but in my experience the X12 has loads of torque, more than most motors! It seems that because the stock setting is to retard the timing as much as possible (by using the 4 dot) this tends to aid the torque as well.
In all honesty the X12 is just a completely different motor to anything else out there in stock land... but find the sweet spot and boy it's fast!

For most motors, I do tend to go higher than most on the start RPM, as personally I don't think adding in timing so early is needed... again, from experience and driving round with a data logger, the motor will rarely dip down below 5k - 7krpm on the track (TC, 2s). Yes, this is motor dependent, but that figure is a good ball park.

In which case, IMO, there is no point having the timing added earlier, as all you are doing is in effect adding static timing (i.e. it's always in the rev range). A higher start rpm allows the static timing/torque do its job, before bringing in the extra... and with an X12 with large amount of inbuilt static, it doesn't need that added. For other motors with less static (or no adjustment) then maybe it's worth starting lower to give a bit extra hand. Anyway, just my opinion

Hi again Ed,

New additional info i got here from your post as I do not have data logger around. So what you're suggesting is that the start rpm to be at around this value of beyond the 7K rpm? Will this also depend on the track?

P/S : The race last weekend does not go very well but may be will have a practice today to try your suggestions.
Thanks.
