7. Technical Requirements:

8. 2020 410 Rule Additions:
  1.  410 HP and/or 410 Torque is the MAXIMUM for     any car in the 410 Class. Any amount over 410 in   either HP or Torque has two options:
    1. Score in the Open Class
    2. Adjust down to meet the 410 maximum.
  2. Only one ignition is allowed per car: MSD 6…
  3. You must test the HP/TQ up to the limit of the rev chip. Rev chips are set by the car owner. HP/TQ/RPM are all recorded at the time of the official dyno test.
  4. GASS Racing will provide RPM readers to be installed in every 410 Car.
    1. If it is determined the RPM’s exceeded due to issues other than a mechanical down shift – the car will be scored in the open class for that single race.
  5. To achieve 410 HP/TQ – a restrictor plate is allowed. You may also lower the RPM limit by using a lower RPM chip.
  6. NO Fuel Injection Engines are allowed in the 410 Class. If you have fuel injection you will be scored in the open class.
  7. Dyno Test Day: If an entry exceeds 410 you will have one chance to re-tune and meet the 410 maximum for a 2nd test. If you go over 410 in HP or Torque after the 2nd test (must be done prior to Qualifying) you will start at the back of the dyno testing line to try again providing you succeed in lowering your HP/TQ – however if we run out time you can run in and be scored in the open class for that day.  
  8. GASS Racing does not charge for dyno use. The dyno will be available for use the day prior to race weekend. Use is based on the availability of Jenn Biller, Mose Wahlstrom, and/or Adam Tumblin.
  9. Note: You must weigh a minimum of 2850. There will no longer be the option of a handicap for weights due to HP/TQ exceeding 410.

The top 3 cars will be dyno’d after each race. Determination to be scored in 410 or open will at the discretion of the GASS board.

9. Rule Interpretation: All decisions made by               GASS are final.
