noooooo, torque for throttle, the ideal speed for throttle is between .16 and .14, and at least 100oz-in of torque to operate the brake effectively. If you go faster than that, you can open up the throttle too quickly and bog. In the excitement of a race it's easy to do and will cost you time. That's my 2c anyway.

For the steering, fast as you dare, and anything over 100oz-in...
