Greetings from Pack 391


Thank you for visiting our website. Our goal is to keep you informed of our activities, notify you of changes, and provide information on our Pack. Did you know that Scouts are more likely to graduate from college and pursue post-graduate work than non-scouts?

If you are new to Scouting we recommend you view this brief video:

  • The overall height of the car shall not exceed 6 inches.
  • The car must have 1 ¾ inches clearance between the wheels.

  • Only official BSA Pinewood Derby wheels may be used.  You should be able to see raised lettering on the outside of the wheel with "BSA" on one side and "PINEWOOD DERBY" on the other.  The wheels included with the pack-supplied Pinewood Derby car kit are fine, and the wheels on many other car kits are fine.  However, some wheels are not.  If you have any question, please contact your den leadership.
  • Very few modifications to the wheels are allowed.  In general, anything that would remove material from the wheels is not allowed.  You are allowed to:
    • Use sandpaper or lathe to true out-of-round wheels
    • Add material like glue or fingernail polish to the inside of the wheels to balance them.
  • Axles must be nail-like with a head.  "Through" axles that span the width of the car are not allowed.
  • Wheel bearings, bushings, or washers are not allowed.
  • Axles may be altered, polished, or lubricated (dry lubricant only).

  • The front of the car must not extend past the center of the front of the car where the gate will hold the car at race start.
  • All cars must be dry of paint, glues and able to be handled by official or the will be disqualified until corrected.
  • Once a car passes inspection and is entered into the race, only race committee members can touch it.
  • If the car loses a wheel, or is otherwise damaged, the racer shall have 5 minutes to make repairs.
  • Each car must pass inspection by the official inspection committee before it will be allowed to compete. The Inspection Committee has the responsibility to disqualify those cars that do not meet these rules.
