Performance curves are a bit tough to read, but http://evdrives.com/images/Motors/ME...o_ME1003-1.pdf states the Mars turns 3000 RPM at 72V. Both motors look to have similar torque in the 400 to 450A range. Mars being a PM motor has a flatter curve, but I don't see that as a factor. And I am surprised the mars can tolerate the high current.
We had 60 foot times best was 2.88 worst was 2.34 thats from 16 runs 330 times were 6.321 to 6.387. This is bracket racing you dont need the fastest car to win {dragging rights are nice } you just need to be consistant every race and cut good lights.I will gear my car at the next test and tune and try to run 9s but if it losses the consistance i will change back, its a fine line to run, we ran 66 miles hr then changed gearing and only ran 59mph but car is quicker ,but not faster.Spinning is not winning,the gearing is hard to get we played with it last year with the lead ,and will do it this year with the lithium.So you want something that you can change the gearing easy and not to expensive.Im sure i could gear the car to run 70mph but it would be in the 13s,im trying to get in the 9s i dont really care what the mph is its not important to me ,more worried about running the same time every run .And having fun with my kids at the track.
This is a good example: when we ran our electrics together during time trials your mph was 62.14 and ours was 52.35 but our E.T. was quicker. http://www.youtube.com/watch?v=2akGs...eature=related
I think the 60 ft. times are important but to run a 9 second, mph must be at least 60. That is my unscientific WAG.
you sure dont like the mars ?? its only running for 10 secs have had no problems its a light motor and a light car .
I'm not sure what the best motor is for a junior but that ME1003 seems to be doing the job for you. My K91 was something I got used and cheap. It's hard to compare with so few electrics.
BTW, what is the weight of the car without driver?
Didnt do to good this weekend went out first round she had a good light the car just didnt run good .ran 10.35 on 10.20 dial in. I charged the batts on friday and we only got one test run on sat then went racing usally get three runs then race i think the batts were cold ??will try again in a couple weeks charge them in the morning and get some heat in them.I hope that was the problem, cant lose on week cant make it past first round the next , thats racing. were rained out on sunday.

We went out too in the first round but we broke out. Ran a 9.74 on a 9.85 dial in.
Yes, 4 passes: 9.94, 9.93, 9.89,and then a dial in of 9.85 and ran a 9.74 @ 57.4 mph.
60 ft. time of 1.67 was much quicker then the gas cars.
I attribute the 5 mph to the advanced brushes and the quicker times to the tweeking the Raptor controller.

I'm sure temperature has a big affect on the car's performance. We now have a thermometer at the staging area and are logging temp. to E.T.
Our times definitely are related to temperature.
BTW, what does your car weigh?

Re: ev jr dragster
Hey, I'm glad it is working well for you. And I'm glad you're winning 
What did you do differently? mph?
