…These Rules are subject to change at any time. If there is any question,
please check with the track officials for clarification. The current IHRA
Rule Book mandates specific safety requirements for vehicles participating
at all member tracks. Safety requirements specified in the current IHRA
Rule Book for a specific class or E.T. Bracket will be in effect during all
Little River Dragway race events and take precedence over information
contained here. Additionally, Little River Dragway representatives have the
right to disqualify an entry if, in their opinion, the vehicle presents a
potential risk for the driver, crew members, other racers, track personnel
or spectators. THE DECISION OF THE TRACK OFFICIALS IS FINAL.

ENGINE DIAPERS – All vehicles running slicks are required to utilize an engine diaper.

CONDUCT IN THE PITS – Speed limit in the pits is 10 MPH. No vehicle testing
of any type is allowed. NO BURN-OUTS in the pits are allowed. Bicycles,

TRACK POINTS PROGRAM – A racer must register at Tech in order to be
included in the points program. Points are acquired as follows: 25 “show
up” points (must take the tree in the 1st round), 10 points for each round
won. Racers that “buy back” receive no further points.

may be required per IHRA Class Regulations (See Applicable Class
Regulations)

TAILLIGHT – All vehicles in competition at any time the dragstrip’s
nighttime lights are turned on is required to have at least one working
taillight.

RACE VEHICLE BREAKAGE – In order to keep fluids off the racing surface,
racers experiencing problems with their vehicle during any pass are
requested to pull over to pull over to the edge of the racetrack and stop.

DOUBLE ENTRY – No Driver may compete twice in the same eliminator.

VEHICLE CHANGES – No Driver may change vehicles after the first round of
competition.

PASSENGERS – Passengers are not allowed in competition vehicles in any
paired pass. Every passenger pass is done at the Track Starters digression.
Pre-race contact with Track Starter Mandatory.

NON STARTING VEHICLES – In the event a racer at the head of the staging
lanes fails to start their vehicle when called, the racer will receive 60
seconds to crank as timed by the Track Starter while their competition is
held in the water box. A competition single run for the waiting racer will
be called by the Track Starter if the non starting vehicle fails to crank
within the allotted time.

COURTESY STAGING – Where both racers pre-stage FIRST before either
competitor stages is required in ALL Classes. If a racer fully stages
before their opponent pre-stages, the Track Starter will back that
competitor out of the lights completely and start the staging process
again. If the same competitor fully stages again before their opponent
pre-stages a disqualification will be called by the Track Starter.

DEEP STAGING – Where a racer rolls far enough into the staging beams to
turn out the pre-stage light is not allowed. The Track Starter will back
both competitors out of the lights completely and start the staging process
again. If the same competitor deep stages again a disqualification will be
called by the Track Starter.

STUTTER BOXES, TRACK LOCATORS (counters) & SIMILAR DEVICES – Are not
allowed. Use of such devices during any run will result in immediate
disqualification and expulsion from the event. Entry fees WILL NOT be

the PASSENGER SIDE DOOR WINDOW in 4″ to 8″ tall numerals before coming to
the Starting Line.

DIAL-IN – A racers dial-in number cannot be changed after the vehicle has
left the head of the Staging Lane. Each Competitor should check the dial-in
display board on the Starting Line for correctness. If by some reason the
dial-in shown on the display board is incorrect the racer should not stage
and instead bring the problem to the attention of the Track Starter. By the
act of staging, the competitor accepts the dial-in. No dispute or appeal is
allowed.

FIRST ROUND BYE RUNS – Will be determined by a playing card draw. Bye Runs
in following rounds will go to the racer with the best reaction time in the
previous round.

BREAK OUT DISQUALIFICATION – If a racer runs quicker than the dial-in the
track timing system will automatically disqualify the run, giving the win
to the other lane. If both racers run quicker than their dial-in, the racer
breaking out by the least amount will get the win.

CENTER LINE DISQUALIFICATION – The Track Starter will be in charge of any
disqualifications caused by racer crossing the center line of the track.
Any such calls must be made before the next pair stages.

EXCESSIVE BRAKING DISQUALIFICATION – A racer that applies the brakes on his
vehicle hard enough to cause any tire to skid at ANY point in ANY run may
be disqualified at the discretion of the Track Starter.

FIRST OR WORST DISQUALIFICATION – In case of dual infractions of the common
laws of drag racing during an elimination pass, what’s known as the “First
Or Worst” rule applies. In case of the same infraction such as a dual red
light, the first will be called and the competitor that jump started second
will remain in competition.
*Now if the right lane gets a red light but the left lane racer crossed
over the center line which was a worse infraction the racer that had gotten
the red light would have been declared the winner.
*Here is a list of worst in order.
#1 Crossing the center line in front of or along side of your opponent.
#2 red light.
#3 being found illegal.
#4 touching any boundary marker (center or outside).
#5 dropping any foreign matter in front of your opponent.
#6 any condition judged to be unsafe or unfair by event director.

spring which shall close throttle when released. Throttle control must be
operated manually by driver’s foot: electronics, pneumatics, hydraulics, or
any other device may in no way affect operation of the throttle. Throttle
stops, other than mechanical (i.e. a positive stop under throttle pedal)
prohibited. Must be mounted securely (wire ties prohibited).

FRAME BALLAST: Must be secured to frame with a minimum of one 3/8 bolt per
5 pounds. Hose clamps / ties wraps/ etc may not be used to attach ballast
to the entry. No ballast may be installed on the vehicle higher than the
top of the rear tires.

CATCH CANS: and lines must be securely fastened.

DEFLECTOR PLATE: A deflector plate of a minimum 1/16″ aluminum must be
installed between roll cage and engine extending from lower frame rail to
the top and width of driver’s helmet. Carbon fiber prohibited.

GROUND CLEARANCE: Minimum three (3) inches front of car to 12 inches behind
centerline of front axle. (2) inches for remainder of car.

ROLL CAGE: Mandatory five-point roll cage. Upper frame rails-minimum 1 1/8″
diameter by .083. Diagonals-minimum 3/4″ by .083″. Uprights in driver’s
compartment must be spaced 20″ or less. Must conform to standard dragster
configuration as outlined elsewhere in this guide. Mild steel chassis
prohibited in the Master classification. Note: cm may be used in place of
.083 ms.

SHEET METAL: Driver compartment interior must be aluminum, steel or
fiberglass. Magnesium prohibited.

STEERING: All components must have a positive through-bolt or welded
connection. All rod ends must be of aircraft quality or better, and they
must have a bolt through with lock nut or drilled and cotter keyed.
Steering must also have washers on bolts to keep rod ends from pulling
through. Minimum spindle diameter is 1/2″.

WHEELBASE: Dragsters Minimum 90″. Maximum 150″ on long side. Maximum 2″
wheel base variations from left to right. Funny Cars 70″ to 95″, Roadsters
65″ to 95, (2″ variation maximum).

INTERIOR SEAT: Properly braced and supported seat constructed of aluminum
or fiberglass mandatory.

UPHOLSTERY: Optional.

RESTARTS: After initial start-up, one chance will be given to restart the
car within a reasonable time at the starter’s discretion. The crew person
should keep the starter close by in case it’s needed. Push starting any
vehicle is prohibited.

STAGING: Once an entry reaches the front of the staging lanes for a run, it
must be prepared to fire and race. In order to be a legitimate race winner,
the competitor must start and self stage the vehicle under applied power.
This rule also applies to single runs. All competitors will be given
reasonable time to re-fire their entry, provided it is not prestaged. The
amount of reasonable time is determined by the starter. Crew members are
prohibited from touching the vehicle after it is pre-staged. Crew members
touching the vehicle once it is pre-staged will be disqualified.

STAGING: “Auto Start” will be used in all classes at all IHRA events. Once
both cars are pre-staged and the first car fully stages, the second car has
a predetermined amount of time to stage before the tree is automatically
activated. This predetermined amount of time is referred to as “Time Out”.
If the second car fails to stage before the system “Times Out”, it will be
given a red light. If either car rolls deep after “Auto Start” has been
activated, the competitor accepts the deep staging and will not be pulled
back. “Courtesy Staging” is mandatory at all Junior events in all
categories. If a competitor unintentionally lights both bulbs before the
opponent stages, the starter will pull the vehicle back and allow to
re-stage. This is considered a “pull back” and will only be permitted one
time. The starter has full control and is the only one who may pull back
car whether it is pre-staged, staged or overstaged.

DEEP STAGING: Is allowed but not guaranteed. The auto start system will be
activated when both cars are pre-staged, so if you are staging deep you
should do it in a timely fashion. Crew member may assist the entry in the
pre-staging of the vehicle. Once the entry is pre-staged, crew members must
be behind the vehicle and out of both competitors view. Pull Backs in the
case of over staging are permitted one time if time permits. If the auto
start system cycles during the pull back, the run will stand.

THE FINAL STAGING MOTION, USING APPLIED POWER, MUST BE IN A FORWARD MOTION
GOING FROM PRE-STAGE TO STAGE.

SUPPORT GROUP COMMUNICATIONS: 2-way communication of any kind is
prohibited. The use of any handheld portable device such as an MP3 players
or iPod is also prohibited on race track or any time the competitor is
seated in the vehicle.

COMPUTERS: Prohibited. See General Regulations for specific information.

DELAY BOXES: Prohibited.

DATA RECORDERS: Permitted. May be utilized to record engine RPM, cylinder
head and exhaust temperature. No sensor of any type may be used on the
front wheels or spindles. All data recorders and related components
including switches, push buttons and wires must be located outside of the
driver’s compartment and isolated from the drivers view. Data recorders may
only be activated by a crew member and must be done before the entry Pre
Stages. The units may not display any information to the driver or remote
location. A tachometer that incorporates download capabilities is
classified as a data recorder. (See General Regulations: Data
Recorders/Electronic Devices for specific information.)

GAUGES: Engine and Cylinder head temperature gauges are permitted. A
tachometer meeting specific guidelines is also permitted. (See General
Regulations: Data Recorders/Electronic Devices for specific information).

STAGING DEVICES: Mechanical, hydraulic, electric or pneumatic staging
systems prohibited
