how to detect correct brush strenght?
what are most important things what
everybody should do in stock motor
to tune it up and get more speed out of it,
by rules that you can't change spur and pinion gears.
??
also i have heard that is possible to tune up two "simmilar' T27 engines, but
one of them will be very powerful and fast, while other engine will be very smooth?
how to change it and what are the reasons for sutch different behavior?
thanks
So, how far down this rabbit hole do you want to go...
Not knowing the application, I would suggest doing the following as a general way to extract more power from a 27T stock motor.
1. Purchase a set of quality silver brushes from Trinity/Epic and install them.
2. Pick up a Medium and Heavy set of brush springs for medium to high speed application or a set of Heavy and Extra Heavy springs for a high load/torq application such as sc trucks and 4wd...
3. Install the medium/heavy spring on the positive side of the motor
4. Install the heavy/xheavy spring on the negative side of the motor
5. Fill Large glass full of tap water
6. Run motor on 3-5 volts (2 or 3 NiMh cells)
7. Dunk motor in water running for 5-7 Seconds and and remove from water and shut off promptly. Clean motor very well with motor spray.
8. Check brushes to make sure they are fully seated (Wear contact patch across the entire face of the brush, If not fully seated repeat step 7.
9. Oil motor bearings/bushings and run for 30 seconds on 3-5 volts.
10. The motor will give it's best 3 - 5 runs under these condition before you should inspect and clean brushes.
This is a very short version of how to get the most out of your motor. Their are MANY other small details and black magic arts to getting a bit more out of a stock motor but in order to really gain from there you have to make sure your car/driving and gearing are all spot on...
Good luck, let me know how it works out...
