Yeah, I have a P-94 15 turn double wound motor with a 48 pith 19 tooth pinion and a 48 pitch 78 tooth kevlar spur gear on a Losi Triple-X BK2 buggy with a novak explorer2 and a team orion vmaxx battery @2400 MaH, The setup seemed a bit slow, but the pinion was messed up and the motor wasnt properly connected, but how would I maximize this setups performance??? I also would like to know what I should time the P-94 at abd how I should go about adjusting the timing.

The way you adjust timing is clockwise rotation reduces it, while counter clockwise increases the timing. There is the area known as the zero degree area that going beyond that will cause the motor to rotate in the wrong direction.
Timing as the following affects.
Increasing timing to certain point increases the rpm or acceleration at a decrease in runtime. Most motors come preset from the manufacturer set at the timing that produces the best combination of rpm and torque which varies from 6-24 degrees.
Decreasing the amount of timing reduces the rpm levels and acceleration, normally increases torque output and increases the runtime.
With modified motors the first thing to do is gear according the motors expected power output normally use a taller spur (83-87) with the correct pinion size. Then adjust the actual gearing changing pinion to suit the conditions the vehicle is being run or the timing you use.
Since the motor is making more power than a stock motor, the taller spur will let it wind up smoother, find what gear (final drive ratio the is suggested with your vehicle and try gearing up and down) until you achieve the right result. If you advance the timing from it's present position be prepared to gear down one tooth and if you reduce timing gear up - you need to adjust gearing for differences in the motor's output.
Also altering the timing if done incorrectly may lead to more problems, increasing it will causing brushes and comm to wear motor and in some cases spring tension may not be adaquate at higher rpms levels - that may lead to brushes bouncing excessively, wearing out or causing glitching problems. It may be more ideal to invest in a motor timing guage to be able to read the amount of timing or adjust it correctly.
I can't even began to suggest what will be an ideal setting for you to use, generally it's a trial and error until you find the right combination. I find 78-81 spurs a bit too small to be used in vehicle other than for bashing.
