Although the relationship isn't always linear, the general rules of thumb are as follows:

Most motors have somewhere around 28-30* of mechanical timing built into the design when the indicator is at the 0 or 'big line' reference mark, with somewhere between 4-8* for each line after that.

I believe somewhere on this thread the new scale and indicator of these motors indicate ACTUAL timing (although I may be wrong).

Edit: Found It!! (emphasis added)

Thanks for the info, I was looking for a good starting point. We have a new layout that I have not been on yet, so Im not sure on how were going to gear the touring cars. Im starting at a 4.08 fd with 30 on the timing and blinky mode for 17.5 stock touring. Depending how long the longest stretches are I may add for more rpm's or lower to get some GO. We'll see

does each line on the can represent 10degrees of timing?
Look at post #71 & 72 on page 5 to see the two types of can.

The bigger picture (newer can) is actual timing numbers.

Thumbs down

I am running the new sonic 17.5 in 1/12 and I am wondering if here is a 1s rotor for the motor because I can not find it anywhere on the net.... Help please

Go for the 12.3x24.2 for 1s

There is no rotor that we designate as a 1s rotor. We offer tuning rotors.
We, the team, have just been running the motor the way it comes from the box. But if you want to try running a weaker rotor try #954, 12.3x24.2 w 7.25 shaft.

Your running non-boosted?
I haven't raced that myself but would guess a rollout of 100-102mm maybe more, depends on the size of track your running. How much timing are you using in the motor?

Hey Sean,
with a 1/12th scale 17.5 blinky rollout of around 100-102mm as you have suggested in your recent post (still using the standard rotor that comes in the motor), what timing setting would you recommend as a starting point? Mine is one of the newer edition Sonics with the revised timing pointer.

Yes I guess that might be in the right vicinity. I would go with 27-30 degrees of timing for boosted. Boosted is alot more complicated obviously. What SC are you using?

I would start at 40 degrees and go from there. I ran 13.5t NB last month with one of the older motors and only ran about 30-32 degrees. It was still fast but I would have liked to see what more could have done.

so just so i'm clear here,the can in post #72 with no numbers on it only makings is the older can yes ?????ok so if its set in the middle like the picture
at 0 is there any inbuilt timming when at 0 if so how much & each increment of timimg (+ or -) is worth how much timing ????
appreciate any feedback,thanks

Lrp sxx stock spec and it has been updated recently .... Settings are 0-10-12 on speedo , on the infield I can stay with everyone then when I hit the straight away I get passed. I love the motor and am trying to figure out what I'm doing wrong.Temp of motor comes off at 149...

Yes the motor in the photo is the original version of the Sonic.
Where the pointer is in the photo, middle of scale, equals 15 degrees timing.
All the way to the right and that is zero, all the way to the left and that is 30 degrees. Each mark equals approximately 4 degrees timing.

Ok let me run down the list so I'm clear.

SXX-SS with v4.4sw 0/10/12/0
Reedy Sonic 17.5t with 80mm rollout

What timing on the motor?
Everything you have mentioned so far seems ok.
I'm guessing the timing in the motor is low, but I need to know before I can go further.
Also are you confident that you aren't getting cheated by others you are racing against? If you are truly getting pulled that bad on the straight that doesn't sound right, alittle difference due to not having a good set up is reasonable. But if someone is really pulling you I would be inquireing about what they are doing.
