…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

All vehicles running slicks are required to utilize an engine diaper belly pans.

CONDUCT IN THE PITS – Speed limit in the pits is 10 MPH. No vehicle testing

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.

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

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

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

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).

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.


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.


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
