1.General Rules
Rules apply to all classes unless otherwise specified.
A. TRACK OFFICALS DECISION WILL BE FINAL. ANY
DISAGREEMENT ON THEIR DECISION ON ANY POINT OF
CONTROVERSY WILL RESULT IN DISQUALIFICATION FOR
THAT CLASS FOR THE DAY.
Comment: The track officials have the final say on what happens on
the track.
B. YOUR TRACTOR MUST MEET ALL SAFETY AND
SHIELDING REQUIREMENTS PRIOR TO HOOKING
OTHERWISE YOU WILL NOT BE ALLOWED TO COMPETE
AND THERE WILL BE NO REFUND OF ENTRY.
2.Track Operations:
A. Driver must put his tractor in a neutral position and be hand
pushed to the sled. Tractor must be shut down before chain will
be unhooked from tractor.
Comment: Flag men will enforce this rule for the safety of the track
help. See Rule 1.
B. No portion of the tractor shall interfere with the sled hitch during
pull.
Comment: Many times the starting line becomes torn up, which will
cause the front of the tractor to be lower than the rear tires. This may
cause an interference of the cross bar for the wheelie wheels. The
intent of the rule is not to interfere once the pull is underway.
See Rule 1.
C. Any portion of tractor touching boundary line during pull will
result in disqualification. This would be limited to the front or the
rear tires. There is no out of bounds once the tractor passes the
full pull mark. See Rule 1. The entire tractor must pass the full
pull mark.
D. Two attempts will be allowed to start sled except in pull-offs.
One attempt only in a pull-off.
Comment: An attempt is considered once the hook goes in the hitch
and driver physically tries to start the tractor in motion by revving up
the engine and attempting to release the clutch. See Rule 1.
E. The first puller can drop five places which mean he or she will
actually start in the 6th position or they can come back
immediately. If they do drop, they drop to the 6th position.
F. If a puller has a mechanical problem they have to drop back 6
positions (five more pull then they hook). If there are less than
five tractors remaining, they have until the end of the heat plus
five (5) minutes. If they are not able to hook within the allotted
time they will receive last place in that heat. THE PULLER CAN
NOT DROP TO ANOTHER HEAT - it would be unfair to the
others in those heats.
G. Driver will be disqualified if he or she delays contest.
Comment: A puller is expected to have their tractor running by the
time the sled gets back to the starting point, If the puller delays more
than 90 seconds he will have to drop as discussed in 2-F.
H. Pulling position will be determined by drawing. The drawing
should be done prior to the event for the heats.
I. Driver must remain seated during pull. Drivers must have at
least on hand on the steering wheel at all times.
J. Weight transfer sled will be used. Either self-propelled or pull
back. Must be a 3 foot chain with the hook point within 2 inches
or less of the ground. All slam bars on sleds must be
mechanically operated. No air, electrical or hydraulic slam
devices accepted. Recommend all sleds be a single axle
design. Tandem axle sleds tend to steer tractors once they are
turned and tractors are more likely to become uncontrollable
than with single axle sleds.
K. Tractors must be operated in a safe manner at all times
L. All weights must be safely secured to the tractor. Any excessive
or obvious loss of weights or components may be cause for
disqualification. The flagman must make the call during the pull.
Any disqualification for loss of weight or component must be
made during the pull. A pull is started when the sled starts to
move and is ended when the sled stops movement, even
though the tractor may still be under power.
M. Track officials have the right to restart the class anytime within
the first seven (7), either for full pulls or short tracking.
N. A tractor can only enter one time per class.
O. A tractor engine can only pull one time during the finals, cannot
be switched from one tractor to another ... AKA "The Black
Nichols Rule". A puller is able to put in a back up engine, but
not from another tractor pulling in the same finals.
3. SAFETY:
A. YOUR TRACTOR MUST MEET ALL SAFETY AND
SHIELDING REQUIREMENTS PRIOR TO HOOKING
OTHERWISE YOU WILL NOT BE ALLOWED TO COMPETE
AND THERE WILL BE NO REFUND OF ENTRY.
B. HELMETS AND FIRESUITS ARE MANDATORY IN ALL
CLASSES, MUST BE ZIPPED AND SECURED. Fire suits must

C. All tractors are required to have a switch that will kill engine and
fuel pump in case of chain or hitch breakage. The switch will be
located within range of six (6") either side of center of back of
tractor with a minimum of a 1.5" circle.
Comment: Make sure it has an adequate size ring in order to ease
connecting to sled.
D. All tractors must be equipped with a dead man throttle.

flywheel and clutch assemblies must be covered 360 degrees
with 1/8" steel or 3/16" aluminum and be securely fastened to
the frame or engine.
L. Engine Dampers must meet requirements of SFI Spec 18.1 is
required. A bolt is required to secure damper to crank.
FLYWHEELS and STARTER PULLEYS must be of billet steel
or aluminum (no cast or stamped steel pulleys). No welded on

pulley from coming off crankshaft.
M. All tractors to be equipped with workable brakes.
N. Fenders: Fenders must extend a minimum of 4" in width and
must cover the front of tire to its furthest point forward. It is
recommended that the foot step be connected to front of fender

for safety and health reasons at any time.

5.Fuel:
A. All tractors in all classes are to run Methanol (unless otherwise
specified), with no additives. There are two U.S. Federal
Grades. Grade A and AA. Either grade is permitted to use.
Pullers should ensure that the methanol they purchase meets
federal standards of purity. Methanol is tested at all
events by various chemical analyses as considered appropriate
Fuel Tech personnel. Deviation from the standards
listed below in the fuel sample will result in disqualification.
Methanol is a hygroscopic substance and readily absorbs
moisture from the air, which rapidly renders methanol illegal as
a fuel for use in NQS pulling. Pullers are cautioned to keep
methanol containers tightly sealed at all times to minimize the
absorption of water.
B. Specification for Pure Methanol:
Parameter Grade A Grade AA
Methanol Content, wt%, min 99.85% 99.85%
Acetone & Aldehydes, ppm, max 30 30
Acetone, ppm, max 20 20

â–Ş Appearance: Colorless-clear
â–Ş Carbonizable impurities
C. Diesel fueled tractors must run diesel only with a dielectric
value of no greater than 4.9 or less than 2.2. The dielectric
meter shall use Cyclohexane to establish the zero reference
point in determining all diesel fuel dielectric constant values.
The use of additives containing oxygen, such as nitro methane,
propylene oxide, dioaxane, MTBE, alcohol (methanol), or
nitrous oxide is prohibited. These additives, and others of the
oxygen-bearing family, will significantly change the dielectric
values of diesel fuel.
D. Gas: must be either VP C-12 or VP C-15 unless otherwise
noted. No oxygenated fuels allowed.
E. Fuel Injection is allowed in Super Stock, Nitro 30 Cubes in Lite
Pro. Unlimited and Open Super Stock Classes (non-dieselfueled engines).

6.Tear Down and Illegal Vehicles
A. All top money winners will have their engines checked for
legality. Teching will include, but not limited to the engine.
Remember, if you don't want the NQS tech official to see parts
of your engine that is not involved with the tear down process,
cover it up. Any person who refuses to be inspected for
eligibility by routine check of money winners shall not be
allowed to enter and/or pull in the class in question until legality
is checked. See Rule 1.
B. Protest of a competitor’s vehicle must be filed in writing to a
track official within 15 minutes of conclusion of class. A
$400.00 cash protest fee must be submitted at that time. Tear
down of protested vehicle must be done by a qualified tech
official with the proper testing equipment. Only the tech person
and the owner of the protested vehicle are allowed to be
present at the time of the tear down. If the vehicle is found to
be illegal the protest fee will be returned. If the vehicle is legal
the protested vehicle owner will receive the fee. Illegal vehicles
will be disqualified for all pertaining classes entered for that
event.
C. Tech Officials can overrule any misprints in these rules.
