Power under load to overcome weight of the car with correct gearing and still be under the limit? Awesome!

Note: Our testing has shown that the new CS (carbon/silver brush) motors will exceed 17,500 RPM @7.2 volts with only minimal break-in.

Like....way exceed.

Like, 19,000 RPM +.

Just so's you knows.

So how does one know if they have such a motor, and if we don't, where can we get one.
Maybe the business now becomes detuning the silvercans

Slow break-in, agressive break-in and so forth. We started to get readings in the high 16950. We took it a step further. We added some drops of water to the brushes to see what happened. RPM increased after we kept breaking in the motor. The highest test was 17610 and that was after the motor was still hot. Remeber, the rules say the RPM will increas 200-300 RPM from a hot to warm motor. We tested that theory and of course the motor dropped to 17200 range. Suffice it to say, we encourage breaking in the motor. We encourage lubing the bushings, but if you're looking to get more out of the motor you're going to go above the 17500 limit and you know...DQ!

So now what?

Handout motors with install and removal process again?

Random motors held in tech and fixed gearing for all silver can classes?

The way I see it, what this discussions (to put it nicely) did is essentially put a halt on moving forward. We halted progress at the moment and with good reason. Hopefully next season FMW will find a good brushless setup for most of the classes. I'm looking forward to that day.

How 'bout we let cool heads prevail. Let's get through the January regional and see what happens. Until then it's mostly hand-waving and speculation.

Just lube the bushings and install in your car.

No need to break in too much.

Then clean, lube and reinstall.

Makes for a less stressful day of racing.

Doesn't running the motor in your car break it in?

I think the way you tell is if you look at the brushes on the motor and they have an "S" printed on the brush. These motors are much stronger than the older 2 slot

Still got time to test and see if any of these 19,000 RPM + motors could show up and ruin someone's day, or if what Doc is sayin begins to happen I'm sure FMW will have a plan to deal with it.

Just gonna need access to the test procedure and equipment to see, maybe even squeeze in a "Fun" race and see how it goes down.

Don't get me wrong- I'm not waving a flag or anything. Just want people to know that the current run of silver cans- the ones that have "CS" printed on the brushes, so they are easy to spot- will exceed the 17.5K limit @7.2 volts after very little run time. And not just one or two of them, pretty much all of them.

We didn't take part in the testing that Fred did, so I can't speak to his results, but if he was using a motor from the previous production run (soft brushes, red pip on positive side of endbell), they might have been slower even when broken in.

Johnson does running production changes and (as very probably the largest non-wholesale consumer of part #53689) we have seen them get better and better over time.

Mr. Hinkley, Bruce and I very well understand "Swifty" statement????
It will be the key to having a competitive motor that will be within the Rules??
"The Dynos are a Huming" I am sure FMW will have Track Officials positioned around the track looking for people who are lifting the Throttle early to protect there motor from scrutinizing????
It will be an interesting year of racing?
Is everybody aware that all venues will have to adopt the "New Silver Can Rules" for 2011??? (Will Memphis Comply with the 2011 Motor Rules????)
