ic, what do most people run when just in the front street?
Most people run stock motors, but my feeling is that there are a lot of things done to stock motors that make them inefficient. Tricks to get more RPM and power out of the motor at the expense of efficiency in order to stay within the rules. The result is more heat and more comm wear.
I think you're much better off getting a mild mod, like a 19x1 (not a 19T spec, for the same reasons as a stock motor)
Stand up brushes in particular will be less likely to arc and cause comm damage.
Adjustable timing will allow you to retard timing to the point that you can virtually eliminate arcing again, easing up on comm wear.
Efficiency will be up, so heat will be down
Ball bearings will add to efficiency as well.
More efficiency is more speed and/or runtime, with less concern for heat.
Stock motors are expensive for machine wounds, and even more expensive to maintain.
A hand wound will be more in initial outlay, but their efficiency will be up, especially if someone can wind it using a slightly larger gauge wire because of the neater windings. Hard to say if the extra money would be worth it?
Whatever you decide, I would go for brushes that wear well, I know the Reedy 729 for standup and 766 for laydown (same compound, just one is laydown, and one is standup) are supposed to be good for that, there are probably others. (Anyone know?)
I see comm wear and heat as the enemy for street bashing, as you don't have a lathe or get somewhere you can have it cut all that often. And heat is bad for obvious reasons.
Stock motors are so bad for heat, that I don't see much use in those kinds of motors for street bashing, they wouldn't last, and a well setup cheaper machine wound mod like a Peak Jaguar or Orion Rush would be both faster and last longer.
People think mod and immediately think comm cuts every run. True if you race competitively, but the flexibility of the mod motor also allows you to back off on the ultimate speed and optimize for efficiency and low maintenance, especially with higher turn mods like a 19 or so. Still faster than a stock with better efficiency and longevity.
