General Rules of the Modern Street Hemi Shootout

General Rules and Procedures


All Race Cars competing in the heads up classes must make a minimum of one qualifying run during race day in order to compete in the elimination rounds. If a racer fails to make a complete run down the track, but does break the start beam, they will qualify in the last position for the class. It will be the track and managing MSHS staff’s discretion as to the number of qualifying runs on race day.

Tree Type

ALL classes will qualify and compete on a .500 PRO TREE except Super Pro, Heavyweight and Outlaw Classes which are .400 PRO TREE.

Elimination Rounds

Pairings will be based on a Pro Ladder (Links: Proladder3-8Proladder9-16-1Proladder17-24). Heads-up classes will be laddered beginning with round one of eliminations. Qualifying slot will be based on ET for all heads-up classes. Identical ET will be laddered based on MPH. All cars that qualify below the Indexed ET are placed at the bottom of the ladder; larger breakout at the bottom.

The Bracket class will begin eliminations pairing up cars randomly, based on how racers proceed to and line up in staging lanes. Once the bracket class is down to 16 or fewer cars, the field of cars will be paired based on a PRO Ladder. Pairing will be based on reaction times during the previous round of eliminations.

Heavyweight Class will be randomly paired using poker chip draws each round!

For classes larger than 24 cars, the first round will be random pairing with the #1 qualifier receiving a bye if there is one.  A Pro Ladder will be used for the second round and on.

If a class has fewer than 4 cars, the finals will be best 2 out of 3. 

Lane choice

Heads-up first round lane choice goes to the higher qualifier in the pairing. Round two and subsequent rounds, lane choice goes to the car with the quicker ET.

Bracket lane choice will be based on reaction times during the previous round of eliminations and should be discussed by the paired racers.


Courtesy staging will be in effect during all elimination rounds.
If a driver inadvertently lights both Pre-Stage and Stage bulbs, it is up to the starter to back out and re-stage the cars, DO NOT BACK OUT UNLESS TOLD TO DO SO.

Deep staging disqualifies a racer from any and all best reaction time awards.

Break Downs

If a racer’s car is NOT capable of moving forward in the competition rounds, they must notify MSHS or track staff timely so that there are no racing delays.

Should a vehicle break down on the track, move over immediately towards the outside of the lane to prevent track delays.

Safety Rules

NHRA safety rules are in effect at all events and it is up to the track personnel to handle all safety rule infractions and or complaints. Track rules must be adhered to by all racers.**


Non-compliance to the MSHS rules will not be tolerated and will earn a disqualification from ALL competition. Disqualification does not entitle a racer to a refund of any entry fees.**

Break Out

Any vehicle running quicker than the Index ET reference in a class is a break out loss.

Safe Racing

All racers should run their car at its full capabilities. Unsafe driving techniques such as hard braking at the top end to avoid a break out will be reviewed and can result in disqualification at the discretion of track officials and/or MSHS staff.
