RACING REGULATIONS

  • All racing will be under the standard PKRA rulebook, except as overridden here.
  • PKRA uses the NKA Rulebook and Briggs LO206 rules for engine tech.
  • Configuration will be Clockwise Short Track, with Pit Entry via turn 2 and turn 1.
  • A transponder is required.  You can use your own or rent one.
  • Fuel tanks are limited to one 3 liter size only, and no excess fuel line is allowed  *** Change from 2021
  • There will be no extra fuel tanks or containers on the kart.
  • Driver Communication
    • Radios are allowed for communication between the pits and driver.
    • There will be a protected pit board location along the front straightaway to allow drivers to easily see team pit boards.
  • Water bottles are allowed.
  • No chain oilers are allowed.
  • No blue flags will be thrown regardless of position;  it is the faster karts responsibility to pass safely.
  • Yellow flags will be strictly enforced, drivers must slow to approximately 50% of race speed when yellow flags are being waved.
  • A Full Course Caution may be used to recover a kart safely, pit lane will be closed in the event of a full course caution.
  • Karts will stop on course in the event of a red flag.
    • Pit lane is closed in the event of a red flag
    • No work whatsoever may be done during a red flag (no fueling, no tire changes, no adjustments)
    • Restarts will be rolling starts in single file order using the “bull ring” oval.
  • Kart Retrieval
    • If the kart has an issue on track the driver can push it back to the pits with the assistance of a track worker with direct supervision and clearance from a race director to get to the outside of the track and back to the pits.
    • The dedicated place for crossing the track will be before turn 1 after the flag stand and on the exit of turn 8.  This is one of the main reasons for picking short track, there are much more limited times a kart has to cross a live track to be retrieved back to the pit lane.
    • A minimum of a 10 second gap between karts is required before karts can cross the racing surface.
    • It is recommended that if a kart has an issue they pull to the outside of the track so they do not have to cross the live track to get back to the pits.
  • Penalties can include time penalties or drive through penalties (with no work performed and no driver change).

TIRES

  • Hoosier R70 is the spec tire and will be marked after qualifying.
  • Tire changes are allowed throughout the race but not required.
  • Maximum of 2 new sets for both qualifying and the race.

PIT STOPS

  • Hot Pit spots will be assigned by qualifying order
  • The pit exit and entry will be the standard layout for short track with the exception of pit
    entry which will be done through Turn 2 instead of using the two straights exit.
  • A track worker at track entry will manage karts re-entering the track, and must be obeyed.
  • When pitting you MUST raise your hand when crossing start/finish failure to do so will result in a 10 second penalty.
  • When exiting the track there will be “stopping” zones where drivers must come to a complete stop with at least 2 tires in the box.  Failure to do so will result in a 10 second penalty.
  • The left side of the pit lane will be the travel lane and the right side will be the pit stop side.
  • Driver changes must be done with the kart engine shut off.
  • Re-Fueling must be done with the driver out of the kart and engine off.
  • Standard fuel jugs must be used for refueling; no mechanical or electric pumps are allowed.
  • Oil changes are optional but not required.  If a team decides to do an oil change a catch can must be used and excess oil spillage will result in penalties.
  • If you do have a motor failure you are allowed to put another engine on in the tech area, both engines must go through tech regardless of condition after the race is concluded if requested by the tech director.
  • Engine changes must take place in the tech area.

KART WEIGHTS

  • Before qualifying each team will report to scales with their kart and ALL drivers to find each team’s average weight without any fuel or lead on the karts or any driving gear on the drivers, pockets must be emptied.  A minimum kart weight will be assigned for each team.
  • After this step the heaviest team’s average will set the minimum average weight for the event and each team whose average is below the set minimum must add the weight differential onto their kart to equal the average weight.
  • The heaviest average cannot exceed the class spec weight for PKRA, for example, the heaviest average for 206 Jr.2 will not be allowed to exceed 310 lbs even if a teams average is above that weight.  206 Sr. cannot exceed 360lbs, and 206 Heavy will cap out at 380lbs.
  • For example, if team 1 has a kart that weighs 185 lbs with no fuel or added ballast, driver 1 weighs 140lbs, driver 2 weighs 150, and driver 3 weighs 145, their average kart + driver weight is 330lbs.  (185+140=325, 185+150=335, 185+145=340, 325+335+340=990, 990/3=330lbs)
  • So, if team 1’s average weight is 330lbs and the heaviest team average weight of the class is 340lbs team 1 must add 10lbs to their kart to get to the heaviest average of 340lbs,. This added weight will stay on the kart throughout the entire race and qualifying.
  • In this example this team’s kart alone, no driver or driving gear must weigh at least 195 lbs when scaled throughout the event and at the conclusion of the race. The kart weighing 195 will bring the teams average weight up from 330lbs to 340lbs.
  • This will be repeated for every class and team to ensure that each team has the same average weight for their respective class.
  • The kart will be weighed after qualifying and after the race has concluded, the officials will keep a record of what each kart needs to weigh and will penalize accordingly.  For each pound your kart is under this weight you will be penalized 1 full lap.
  • No weight may be removed or added throughout the race, bolts and nuts on thevweights will be painted before qualifying and checked in tech following.
