Index Form



ClassCar Eliminator
Formulated Class Index Format

AmericanDRAGCAR 's class index program is ClassCar Eliminator  where  racers are assigned Formulated Indexes based on the technical data provided on their tech sheet that they fill out and turn in during a weigh-in process prior to qualifying.

After qualifying in an "all run" field, racers are laddered in order of quickest to slowest relative to their formulated indexes.

During eliminations racers are handicapped off of their formulated indexes which do not change for the remainder of the race and no penalties are levied for run-unders of any degree.

This is truly all-out class index drag racing.

The DRAGCAR  indexing formula is an equation which takes into account basic engine specifications to establish the power producing capabilities. This becomes factored into the weight of the vehicle and converted into an on-track performance index standard referred to as the Formulated Index.

        The base indexing factors are:

1: Total Vehicle Weight (with the driver)
2: Total Cubic Inch Engine Displacement
3: Actual Intake Valve Head Diameter
4: Gross Intake Valve Lift (@ zero valve lash)
5: Carburetor/Injection Throttle Bore Size
6: Number of Bores (2 barrel, 4 barrel, etc.)
7: Method of Induction (NA, "Blown", N2O, etc.)
8: Type of Fuel being Used (Gasoline/Methanol)

Due to the complexity of this formula having a number of "if" equations, racers wishing to know their indexes before entering into a race must submit an index request form to have their index and minimum weights E-mailed back to them. There is no limit to the number of index requests permitted.

   ClassCar Eliminator Race Format

Upon entering into an  AmericanDRAGCAR ClassCar Eliminator  event, racers receive a tech sheet which must be filled out accurately and completely before proceeding to tech inspections and weigh-in.  Racers will then be assigned a class of competition according to the extent of the vehicle's modifications with a formulated index derived from the racers technical data.  Racers will be notified at this time of their minimum allowable weight for their class and will be afforded the opportunity to adjust their vehicle weight in order to bump up or down a class if so desired.

Qualifying sessions will start off by giving racers a minimum of two rounds of qualifying to establish the field's qualifying order based on performances against their respective indexes.  The quickest run of the qualifying rounds for each racer will become that racer's official qualifying time.  The elapsed time furthest under any competitors respective index will become the Number 1 qualifying time and Numbers 2 on down will be in descending order correspondingly.

Racers will then be placed on a competition ladder for first round pairings.

       Odd numbered qualifiers (1-31) will be placed on the left side of the ladder in descending order and even numbered qualifiers (2-32) will be placed on the right side of the ladder in descending order.
       All first round losers are automatically entered into
SportComp Eliminator  which re-indexes racers on an adjusted index according to their actual performance.

ClassCar Eliminator  competitions will utilize a 4 tenths/5 tenths split Pro tree.

        Delay boxes are permitted.

        All safety guidelines enforced by the hosting facility must be followed.


ClassCar Eliminator
Outline and Rules

Category:  These Eliminators  are run very similar to conventional Competition Eliminators in other popular drag racing venues.

Indexes:  Vehicles are assigned their Formulated Index according to the specifics provided on the tech sheets and qualify against these indexes.

Tech Sheets:  Tech sheets must be fully and accurately completed before proceeding to tech inspection. Racers unable to provide full and accurate technical specifications required will only be eligible to enter SportComp Eliminator.

Scaling:  Racers must scale during tech inspection as well as after each Qualifying Round and Winning Elimination Round.

Changing Classes:  Upon weigh-in during tech, racers will be informed of their class, index, and minimum allowable weight for that class at the classification time and will be afforded the opportunity to adjust their weight in order to move up or down a class.  Moving up or down a class after qualifying has finished will not be permitted.

Tree:  This category uses a 4 tenths full countdown tree.

Deep Staging:  Deep staging is permitted.

Courtesy Staging:  Courtesy staging is not enforced.

Racers must adhere to class lane assignments and class qualifying schedules. Racers will not be permitted to randomly qualify outside of their class qualifying sessions. In instances where a racer has missed all of their qualifying sessions, they will be afforded one qualifying run after all scheduled class qualifying sessions have been completed.

Qualifying:  Qualifying order is established according to the quickest in relation to respective indexes. Qualifying ties will be awarded to that having the higher MPH recorded.

Laddering:  Racers will be laddered according to the ClassCar Eliminator  laddering system.

Eliminations:  Eliminations are run with handicapped starts based off of the Formulated Indexes with the first to cross the finish line being the winner regardless of ET. Except in special circumstances, racers will not be in jeopardy of being re-indexed by running any amount under their ClassCar Eliminator  Formulated Indexes.

Bye-runs:  Bye-runs and competition singles will only require that the racer be present with their vehicle in the staging lanes during the running of their Eliminator. Vehicles must be in race ready condition with no work being performed on them during this time. Racers do have the option of running out their bye run.

Re-runs:  Re-run requests which are not at the order of the tower or AmericanDRAGCAR  will only be granted if both competitors involved agree and both are present to make the request to the race director.


DRAGCAR Protest Procedures

Post Inspections:  While DRAGCAR  does not currently mandate post race teardowns on a regular basis, reasonable suspicion inspections and racer initiated protest procedures may be executed.

Protests:  Any racer (car owner or driver) wishing to do so may initiate a protest of any other racer competing in their category provided that the racer being protested is in fact running further under their respective index than the racer wishing to initiate the protest.

There are two levels of vehicle inspections:
        A Primary "Level 1" Inspection consists of a visual inspection, scale weight, fuel check, throttle bore measurement, gross intake valve lift, and engine displacement pumping.
        A Full "Level 2" Inspection will also include removing one head for actual intake valve, bore, and stroke measurements.

The fees for initiating a racer protest are as follows:
        Level 1 - $200
        Level 2 - $400
Note: 100 percent of the racer protest fee goes back to the protesting racer only if the protested racer is found to be incorrectly classified.

Level 1 protested racers proving to be accurately classified shall be awarded with $150 of the levied protest fee.
Level 2 protested racers proving to be accurately classified shall be awarded $350 of the levied protest fee.

Refusal:  Any racer refusing to comply with the protest inspection will forfeit all season qualifying and race points accumulated as well as 66 percent of all monies awarded at the event of the protest filing, and the protesting racer shall be refunded the full protest fee.

Compliance:  In the event that the protested racer's vehicle is found to be correct as claimed on their technical data sheet, that racer shall receive the full protest fee as compensation for parts and labor.  Said racer's protested vehicle shall also be exempt from any future protests for a period of 6 consecutive months so long as his/her under index performance does not exceed that of any single quickest run during the event at the time of protest by over 1/2 of one percent of that racer's current index.

        Example: Protested racer's index during the event at which he/she was protested was 11.10 and their best posted E.T. during the event was 10.697.

11.10 - 10.697 = Under Index Performance .403
11.10 x .005 = .0555 (round this to .056)
.403 + .056 = .459
11.10 - .459 = 10.641

Exemption:  This protested vehicle is exempt from protests unless it's under index performance exceeds .459 seconds, meaning that if while still running on an 11.10 index at a subsequent event during this 6 month period and it runs as quick as 10.641, no racer initiated protests will be executed on this vehicle.
        The 1/2 of one percent padding is merely to account for changes in atmospheric conditions that may lead to better performances at later events.

        NOTE: Considerable atmospheric conditional changes will be taken into consideration in any event that this may have had an impact on performances being better than those allowed for in the protest policies stated here.

Non-Compliance:  In the event that the protested racer is found to be racing an incorrectly claimed vehicle, that racer shall forfeit all qualifying and race points awarded at the event in which the protest took place as well as 33 percent of all monies awarded at this event.  Their vehicle index will be corrected according to the inspection data and their under index performance will be established based on the corrected index.  This racer's vehicle will now be exempt from any future protests for a period of 6 months as long as their under index performance does not exceed that of any single quickest run during the event at the time of protest by over 1/2 of one percent of that racer's current true found index.  The racer initiating the protest will be refunded the full protest fee in this instance as well.
