NOTES

• • Cars must be capable of 5.40 or better to compete in the class.  If the car does not achieve that ET during quals, proof via previous class performance, time slip or video is acceptable.  Slower than 5.40 cars fit in the 8.50 class perfectly
  • Cars must have an oil retention device
  • Cars must meet NHRA/IHRA safety requirements for ET

  ** Reminder: If a competitor is attending an event to earn class points with an alternate vehicle, they can run in a secondary class.  At the end of the season the appearance points transfer to their primary championship class.  This is to keep cars running in the appropriate class and still allow racers to earn appearance points as designed.

• Drivers will cross over the scales after each pass during qualifying to ensure weight is verified by their competitor AND MSHS STAFF.  **Cars cannot go to the pits after a pass prior to weight verification.  Passing the scales after a pass during elims results in DISQUALIFICATION FROM THAT CLASS**  
• **Forced Induction cars with Nitrous Systems installed will be treated as dual type power adder unless the bottle is removed and nitrous line is disconnected from Nitrous Solenoid.  NO EXCEPTIONS.**  This will be annotated on initial weigh in and enforced each round.  
• **Cars that do not make weight for their configuration during elims are DISQUALIFIED FROM THAT CLASS**
