PROGRAM
NHRA
announces Jr. Dragster program rules changes for 2008 - Dec 12, 2007
The 2008 NHRA O'Reilly Auto Parts Jr. Drag Racing league Rulebook,
which was scheduled to ship to all JDRL
members in December, includes several
changes from last year's edition. Following is a summary of notable
changes for
the 2008 season. As always, racers should read the new book from cover
to cover
to ensure
compliance with all rules.
Protective
Clothing
All JDRL drivers are required to wear a jacket and pants meeting SFI
Spec 3.2A/1 plus shoes, socks and gloves.
Nylon or nylon-type gloves and
socks are prohibited. Open-toe shoes are prohibited. As with all rules,
enforcement of these requirements will be strict, including at
the NHRA O'Reilly auto Parts
Jr. Drag Racing
League Eastern and Western Conference Finals. where all drivers
will be required to present their pants and
jackets at technical inspection.
Helmet Bars
During the off-season, there was some speculation about helmet bars
being added to roll cages in Jr. Dragsters.
Helmet bars will only be required on
cars where the driver's helmet may protrude through the upper roll-cage
members. When helmet are required, a 3/4-inch x .058-inch chromoly or
.083-inch mild steel
bar is required.
Such bars are permitted on all cars.
Driver
Compartment
In the lower portion of the roll cage, driver containment is also being
addressed: With the driver in the normal
driving position, the driver's lower
extremities, including the knees, must be below the top of the upper
framerail.
A steering
crossmember (3/4-inch x .058-inch chromoly or .083-inch mild steel)
must be
installed or a plate or
net must be installed across the upper framerails so as to
retain the driver's feet/legs in case of upset/incident.
Wings
Wings, if used, must be bolted to the frame structure, and wing
supports must attach to the framerails at least
12 inches behind the driver. Ball
lock pins and other quick-release fasteners are prohibited.
Clutch
Guard
The wording in the rulebook regarding clutch guards has been changed to
read in part: "Clutch cover/guard that
provides 180-degree coverage over the
top of the entire clutch plate, cover, hat, arms, springs, etc...
mandatory."
Clutch
Support
If the support bracket and bottom plate are built using a
.500-inch-thick material, it will be allowed to have a
pocket/cavity with a minimum thickness of bracket being .250-inch at
its thinnest point.
Buttons/Switches
The button on the cockpit that is not the mandatory cutoff can be used
for anything except a transbrake or
downtrack stutter. Timed
ignition-interruption devices (stutter boxes) or any action that causes
ignition
interruption
is prohibited.
Taillights
Taillights must be permanently mounted to the car in the manner that
batteries are also secure; tie wraps,
wire ties, hose clamps, etc. are prohibited.
Seat Belts
Where belts are wrapped around the frame members, they must be secured
from sliding along the axis of the
tube/frame member either by a tab or additional tubing.
Fuel System
A maximum limit of one fuel tank on Jr. Dragsters has been added, and
air filters must be properly mounted per
manufacturers' instructions.
Birth-Certificate
Requirement
Jr. drag racers sending in material for participant membership or those
renewing who have never sent in a birth
certificate may now include a notarized
copy of their birth certificate -- a copy taken off a copy machine in
the
presence of a notary --instead os an official government-certified
copy. For

Jr. Comp
In Jr. Comp. it is now required that all fuel lines be metallic,
steel-braided, or NHRA-accepted woven or
woven-pushlock. Also, an engine shield is mandatory between the engine

on the steering or may be operated through
use of a clutch pedal. If a clutch
pedal is used, a hand brake is mandatory.
Transmissions are permitted and may be shifted with a preset
rpm-activated electrical, mechanical, pneumatic,
or hydraulic device only. RPM-based automatic shifters may not have a
time delay incorporated into the
device.
Torque converter belt assembly units permitted in lieu of a
transmission.
As always, two rear-mounted disc brakes are mandatory, but now with a
total car weight of 1,000 pounds or less,
and a one-piece rear axle, a single
rotor may not be used with dual calipers. A hand brake is now
permitted.
If
used, it must be located inside the body or driver compartment.
Timed ignition-interuption devices (stutter boxes) are prohibited.
However, two-step devices are legal unto
themselves but are not allowed to be
altered or installed so as to function as a downtrack rpm controller.
