 ARTICLE I
PARTICIPANT QUALIFICATIONS AND KART SPECIFICATIONS

SECTION I -- JURISDICTION AND ADMINISTRATION

RULE 1 SCOPE OF THESE RULES

These rules of competition are the complete package for the 2011 race. All rules
contained herein will be strictly enforced at all times including, but not limited to,
practices, qualifications, and race. Every person or group of persons who undertake to
organize or participate in the Grand Prix shall sign an affidavit deeming that person is
acquainted with these rules and his participation shall constitute his acceptance of them.
In addition, honorable conduct and good sportsmanship of all participants is expected. By
entering the race and signing a hold-harmless form, the participants agree to abide by all
rules set forth in this rules packet. Every person must abide by the laws of the state of
Indiana and the rules of Purdue University.

RULE 2 DISCIPLINARY ACTIONS

Any unsafe or unsportsmanlike behavior or actions as determined by the
representatives of the Safety Committee may result in the disqualification of a driver,
kart, crew, and organization; or in the cancellation of the race. Any ejection from the race
track for any reason will result in a suspension for the next running day. This includes
being suspended for the race itself. Any violations of the University Regulations will be
subject to disciplinary procedures with the Office of the Dean of Students.

RULE 3 JURISDICTION OF THE GOVERNING BODIES

The Safety Committee will have authority to amend any of these rules at any
time. The technical inspectors will have authority to pronounce any engine or kart illegal
under these rules. Any matter not covered in these rules will be left to the discretion of
the Safety Committee. The Race Chairman is the final authority at the track.

RULE 4 TECHNICAL INSPECTION

All karts and supporting equipment must pass technical inspection before
participation in practice, qualifications, or the race. No changes may be made to the karts
supporting equipment after passing technical inspection except: paint or decals for Race
Day or repairs due to an accident. Passing technical inspection does not guarantee
compliance with these rules. A kart may be protested and/or disqualified because of
noncompliance with any rule in this package whether or not it has passed technical
inspection. Kart and driver set-up must not deviate significantly after passing technical
inspection to the point that it produces noncompliance. Karts must always comply with
the rules. An inspection may be performed before entering the track or after an accident
to ensure compliance with the rules. Each kart will be allowed a total of two scheduled
inspection times. If further inspections are required, a $75 fee will be assessed for each
additional inspection; this does not include re-inspection due to an accident. Any
changes made after a passing of technical inspection shall require a re-inspection

2011 Purdue Grand Prix Official Rules – 7 October, 2010

Information - Specifications - Procedures 3
and a $15 fee shall be assessed. The Safety Committee has the right to inspect any kart at
anytime for any reason. Refer to Article 1 Rule 4 for tech inspection procedures.

RULE 5 TEAR DOWN INSPECTION

The karts finishing in the first five positions at the end of the race shall submit to
a mandatory engine tear down. Any other impounded karts may be required to submit to
this tear down during the impoundment period. All crews shall be responsible for any
modifications found during tear down. Refusal of the crew chief to disassemble the kart
or engine shall result in immediate disqualification. If a kart should use a different
engine in the race than was used for qualifications, then the qualification engine shall be
brought to the tear down in addition to the race engine. During inspection of the engine,
only one member of the official crew and the driver of the kart being inspected may be
present with the inspector.

RULE 6 PENALTIES
Any person or organization violating these rules will be penalized. Penalties may
include lap penalties, suspension from the day's activities, fines, or disqualification. The
Chief Starter will have the authority to pronounce any penalty. If a penalty is assessed
during the course of the Main Feature or a Sprint Race, the crew chief of the penalized
kart will be notified immediately by the Pit Coordinator. The crew chief then has the
option to have his driver black flagged and inform the driver, or the crew chief can let the
driver continue to race.

RULE 7 CHIEF STARTER

The chief starter is the official starter for the Grand Prix. The chief starter is
responsible for all decisions during the race and is in charge of the race from the drop of
the green flag to the waving of the checkered flag.

RULE 8 PROTESTS
Protests between karts shall be submitted to the Race Chairman in writing
accompanied by a $50 protest fee and shall clearly state the subject or action protested.
The protest fee will be returned if the protest is found to be accurate; otherwise it will be
awarded to the Purdue Grand Prix Foundation. Protests must be filed on protest forms
which will be provided in the Race Fact Packs within one hour of the completion of the
race. A crew wishing to protest concerning a sprint race must submit the protest within
five minutes of the completion of that race. The Race Committee will give adequate
notice to all concerned parties of any hearing of any protest before its decision will be
binding, subject only to appeal as provided herein. Rules cannot be protested, only
appealed.

RULE 9 IMPOUNDMENT
All karts involved in a protest will be impounded until final action of the Safety
Committee.

2011 Purdue Grand Prix Official Rules – 7 October, 2010

Information - Specifications - Procedures 4
RULE 10 SCORING PROTESTS
These protests must be in writing on the proper form, and specify exactly what the
protest is. Also, they must be turned in no later than one hour after the posting of the
official results, which will be at 12:00 the Monday after the race. Any protest must be
accompanied by a $50 fee, which will be refunded if the protest is upheld, and received
by Grand Prix by 1:00pm.

RULE 11 APPEALS
Any competitor may appeal any penalty or decision pronounced upon him under
these rules, but the penalty or decision shall remain in effect until the appeal is heard by
the Safety Committee. Appeals shall be submitted to the Race Chairman in writing
accompanied by a $100 appeal fee within 24 hours of the rendering of the decision and
will include a copy of the original protest and reasons for the appeal. The Safety
Committee may confirm, reduce, or waive the original decision, and the appeal fee will
be returned if the decision is reduced or waived. The decision of the Safety Committee is
final.

RULE 4 ROOKIE DRIVERS
All drivers who have not participated in a previous Grand Prix are required to
attend the walk through, and rookie practice. Failure to attend these events will prohibit
the driver from participating in any Grand Prix race activities. If the driver cannot attend
these events then he/she must notify Race Committee prior to the scheduled events.
RULE 5 RELEASES
All race participants shall have a signed hold harmless/release agreement on file
with the Grand Prix Foundation before a pass will be issued to them. Participants under
18 must have the agreement notarized by the signature of a parent or guardian. Only
authorized representatives of the Safety and Security Department will be admitted to the
infield area without a pass. Signing of these releases also indicates a participant
understands and agrees to abide by all rules in this packet.

RULE 6 PIT PASSES

Pit passes, in the form of a picture I.D. badge, will be issued to the crews upon
passing technical inspection. All drivers and crew members must have pit passes and
their Purdue I.D. readily available to any Grand Prix official. Pit passes are not valid
outside of the pit area. Crews must sign up for picture time the day the kart is entered.
The I.D. badges will be provided at no charge if the entire crew has their picture taken
together. A fee of $5 will be assessed for each badge if the crew does not attend the
photographing session together. A lost pit pass will require a $15 replacement fee.

RULE 7 NON-MEMBERS IN THE PITS

If any person is in the pits who is not an official member of a crew, and that crew
is aware of his presence, that kart and crew will be disqualified from further participation
in Grand Prix for that year. The race chairman, pit coordinator, and safety committee
shall have complete discretion.

RULE 8 CREW SIZE

A crew is to consist of a driver, crew chief, track-worker and four crew
members. The maximum size of any kart crew, including driver, crew chief, track-
worker and crew members shall be limited to seven persons. No person may be a
member of more than one crew. A track-worker must be present and able to work
every practice that their team participates in. If no track-worker is provided a member
of the crew will act as the track-worker for that day.

RULE 10 ROLE OF THE CREW CHIEF

The crew chief is the official spokesman of the crew. No one other than the crew
chief shall handle a situation with the safety officials or the race committee.
He is responsible for all actions which these rules may require him to do, including
securing written approval for material substitutions, and innovative designs and signing
the crew score sheet within the allotted time of one hour following the end of the race.

RULE 11 CREW CHANGES

The roster of crew members may be changed by the crew chief at the Grand Prix
office only. All crew changes must be made on the Official Crew Change Form, provided

2011 Purdue Grand Prix Official Rules – 7 October, 2010

Information - Specifications - Procedures 6
by the Grand Prix Foundation. After March 3, 2011 no crew changes will be approved.
Only six pit passes will be issued to a kart at any one time. Illegal transfer of passes is
grounds for revocation of that pass. A $15 fee and the crew identification badge of the
retired crew member must accompany each individual crew change after March 3, 2010.

RULE 12 RELIEF DRIVERS

Crew members who are eligible, (according to Article I Section II, Rule 1) may
act as relief drivers for their crew during the race, at the discretion of the race chairman.
The crew chief must inform the pit coordinator when a driver change is made during
practices or during the race. Relief Drivers will be marked with a highly visible “X” on
the back of their helmet.

RULE 13 SPONSORS
Recognizing the high cost associated with fielding an entry and wishing to
encourage the involvement of area businesses in Grand Prix, the Grand Prix Foundation
endorses the recruitment of commercial sponsors for individual entries. Kart crews
interested in recruiting their own sponsors must clear their sponsors through Grand Prix
before entering into any agreement. Any information given to the Grand Prix Foundation
before recruiting a sponsor will be held in confidence. No team can be sponsored by
any organization or business associated with alcohol or tobacco, or things of a
sexual or denigrating nature. This rule includes businesses that are bars, or the bar is
not set apart separately from a family area. The race chairman has final say on any
discrepancies with the rule.

RULE 14 ELECTRONIC DEVICES

Electronic devices are not permitted in the pit area or on the track. If a crew
member, crew chief, or driver is caught using an electronic device in these restricted
areas, this will result in a Black Flag for their respective kart and disqualification for that
day as well as the next running day. The only exception to this will be approved radio
communication with the driver.

SECTION III -- WEIGHT MINIMUM RULE

RULE 1 OFFICIAL WEIGHT LIMIT

Weight for kart and driver to meet: 350 pounds.
RULE 2 ADDITION OF WEIGHT
All non-structural weights added to meet minimum kart/driver weight
requirements must be bolted securely to the kart. Bolts of minimum 5/16" diameter must
be used to secure weights and these bolts must be cotter-keyed. Mounting of weights to
nerf bars is prohibited. No plastic containers holding water or metal pellets are allowed.
Filling the frame structure with metal pellets is also prohibited: if caught filling frame
tubing with metal pellets your kart and team will be disqualified. The safety attachment
point of the weights and the manner in which the weights are attached has to pass the
safety officials inspection. If the attachment of the weights does not pass the officials

2011 Purdue Grand Prix Official Rules – 7 October, 2010

Information - Specifications - Procedures 7
inspection, then the kart and crew will not be allowed to participate until all safety areas
concerning the weights are met.

RULE 3 WEIGH IN PROCEDURE

-Each kart and driver will be weighed at tech inspection to give the crew an idea
of how much weight to add.
-On the first day of practice of each week the kart and driver will be able to
weigh in to make sure weight minimums are being met. Weight minimums must be
met for the last week of practice.
-On qualification day the kart and driver will be weighed. If the weight is not met
then the kart will not be allowed into the pits until weight is met.
-After a checkered flag is taken in qualifications the kart and the driver will be
weighed again as part of the inspection procedure after each checkered flag qualification
run. If the kart and driver do not meet the weight minimum, then your qualification run
will not count but it will count as a checkered flag taken.
-On race day, all karts will be inspected as usual as you enter the race. You will
not be forced to be weighed in as you enter the pits but the scales will be available to
check your weight if you need to. At the conclusion of the race, the top 5 karts and
drivers will be weighed before being loaded into the trucks to be taken to technical
inspection. If any of the top five finishers do not meet the weight minimum at the
conclusion of the race, then they will be disqualified and they will lose their finishing
positions.

SECTION IV – SAFETY EQUIPMENT

RULE 1 AVAILABILITY OF SAFETY EQUIPMENT

All safety equipment to be used shall be brought to inspection and shall also be
available for re inspection at any time.

RULE 2 HELMETS
Helmets must be full faced, a minimum of Snell 2005 approved, and not older

extinguishers must be on hand when the kart is being started. Carbon Dioxide and/or
Halon extinguishers are preferred.
A fine of $5 will be assessed each time any team needs its fire extinguisher
resealed after qualifications.

RULE 6 DRIVER RESTRAINT SYSTEMS

A driver restraint system is required on all karts. A driver restraint system consists
of lap and shoulder belts. All belts must be securely fastened to the main frame or to a
fixed bracket system. No belts or belt supports may be attached to the roll cage, nerf bars,
or bumpers. Commercial restraint system mounting hardware is recommended. U-bolts
are not allowed to attach the seat belts to the frame. The shoulder harness bracket system
shall be designed so that a load applied in any direction will not result in any movement
of the shoulder harness bracket. Shoulder harness straps/belts must be positively retained
to any harness support. For example a metal rod with cotter keys on both end so that
straps do not fall off of shoulders. Mounting brackets should be installed at an angle that
is compatible with the direction of pull on the webbing under full load. A minimum
specification for bolts and washers to attach the driver restraint system hardware is Grade
8. Under no circumstances are bolts inserted through belt webbing acceptable for
mounting. Belt webbing may be required to be replaced if the webbing shows signs of
wear, tear, and age. Belts with webbing inspection date of more than three years may not
be acceptable. SFI rated belts and harnesses are also strongly recommended. Belts that
exceed three year tested date may be sent in to SFI for re-evaluation. Safety belts are
required to have a width of at least three inches (3”). In all cases, documented
instructions from the manufacturer on the proper installation of the driver restraint
systems shall be presented at technical inspection if a significant deviation for these rules
exists. Proper fit is at the discretion of the safety and race officials. See the diagram in
the back of the rule packet for further clarification.
All karts must be equipped with commercially made arm restraints, which do not
allow the drivers arms to extend beyond the roll cage. The arm restraints should be worn
according to the manufacturer’s recommendations. They should also be a different color
than the driver’s suit.

or cage. The fuel tank must be mechanically secured in such a way that if the connector
between the tank and the fuel line is breached the tank will remain in position.
Fuel tanks must incorporate either a check-valve or an approved vent relief cap
into the vent system. This means the fuel fill cap must be positively sealed so the fuel
tank is vented to the atmosphere through the check valve or vent relief cap. The venting
mechanism must be installed in a safe manner as determined by the technical inspectors.
No silicon rubber will be permitted and hose barbs should be silver soldered to the vent
cap. Venting mechanism must not allow free flow of gasoline in the event of a rollover.
Any check valve or vent relief cap not properly functioning will result in immediate
expulsion from the event in which that kart is participating.

RULE 12 EXCHANGEABLE FUEL TANKS

Exchangeable fuel tanks are fuel tanks that can be removed and replaced with an
exact duplicate. Elasticized fasteners will not be allowed to secure fuel tanks. These
tanks must meet Article I Section V, Rule 11. The design and the final product must be
approved by the technical inspectors before being used but technical approval of the tank
in no way indicates approval of the volume. Only one fuel tank will be permitted on a
kart during the race.

positions at the beginning of the order. This order of draw will be the official and final
order of qualifying.

RULE 2 WARM-UP PRACTICES

On Qualification Saturday, the track will be open for one-half hour practice at
11:20 a.m. The odd numbered karts will be allowed to warm-up during the first 15 min.
period and the even numbered karts will be allowed to warm-up during the second 15
min. Period. Any kart participating in the wrong warm-up group will be subject to
penalization. When warm-up is completed, all karts will proceed to the pits to await
further instructions.
RULE 3 DRIVERS
One individual driver can qualify only one kart and must drive that kart. If a
driver different from the qualifying driver drives the kart on Race Day, that kart will be
eliminated from the starting field. If, for some very unusual and unforeseen reason the
qualifying driver is unable to drive the kart on Race Day, the Race Chairman must be
notified and he/she will decide if the reason is acceptable. If acceptable, the kart may be
placed at the back of the starting field.

RULE 4 QUALIFYING PROCEDURES

When the track is open for qualifying, four teams will be brought to pit out. After
a representative from Grand Prix speaks to the four drivers, they will have seven minutes
for qualifying. During these seven minutes the qualifying teams are able to enter and exit
pits as needed.
During each qualify run, time will be kept for every lap via computer. In the
event that the computers fail, that qualifying run will stop and the four teams on the track
will get another seven minute session. At the end of the seven minute session the
computer will stop. Drivers will be allowed to finish the lap that they are on when time is
up. Qualifications will only occur if all teams are able to attempt in one day. In the
event of poor weather on qualification Saturday we will hold qualifications on the next
day, Sunday. In the event of poor weather on Saturday and Sunday, half of the field will

2011 Purdue Grand Prix Official Rules – 7 October, 2010

Information - Specifications - Procedures 22
qualify on Monday night of Grand Prix week and the second half of the field will qualify
on Tuesday of Grand Prix week.

RULE 5 EXAMINATION
All karts, which accept their runs, must apply the brakes of the kart and securely
lock both rear tires before reaching the pits. Any kart failing the brake test will be subject
to re inspection. All karts must also submit to a short examination so that a fuel sample
may be taken. Karts are also required to demonstrate that the kill switch of the karts
works at inspections. TEAMS WHO FAIL THE KILL SWITCH INSPECTION
WILL HAVE THEIR QUALIFICATION LAP TIMES REMOVED. These karts
will have to have their kill switch inspected again before sprint races and will be
positioned behind karts that recorded times at qualifications during the sprint races.
Those karts, which take the pole position and the second position, may not re-enter the
pits until they are bumped off by another kart. Any qualifying engine may be subject to
tear down. The top two engines will submit to a mandatory engine tear down
immediately following the first day of qualifications. The top two karts from the sprint
races will be inspected after each sprint race.

RULE 6 NUMBER OF ATTEMPTS

Each team will be allowed one (1) seven (7) minute session for qualification.

RULE 7 OFFICIAL QUALIFYING TIME

The official qualifying time will be the fastest single lap time that the driver posts
during his/her qualifying session. In the case of two karts qualifying with the same time,
the kart which posts that time first will be placed ahead of the other kart.

RULE 8 QUALIFYING POSITIONS

After all teams have had the chance to qualify, the fastest kart and driver will be
awarded the pole. The next fastest twenty-six (26) teams will be in the main event in the
order of their time. The remaining teams that did not make the main event will be split
up into three heat races to take place before the main event on race day. The top two
finishers from each heat race will be added to the end of the starting lineup for the main
event. In order to be qualified for the sprint races the teams must complete one full lap
during their qualifying session.
In the event of poor weather and we are unable to qualify on Saturday or Sunday,
the fastest (13) thirteen karts will be in the inside row of the starting grid that qualify on
Monday. The fastest (13) thirteen karts that qualify on Tuesday will be in the outside
row of the starting grid. The rest of the karts that failed to qualify will be in the sprint
races as stated above.

RULE 9 LEAVING THE PITS

Once a kart has attempted their qualifying run, the kart is free to leave but cannot
reenter the track on that day. The top two karts will be held until the end of the day by
the race committee. Once a kart enters the pits on Race Day it may not leave. Doing so
disqualifies the kart. Karts cannot leave the pits after sprint races even if they do not
make the main event.

 SECTION III – Helmet Information

What are the differences between the SA, M and K standards?

SA Standard was designed for auto racing while M Standard was for
motorcycling and other motorsports. There are three major differences between
them:

1. SA standard requires flammability test while the M standard does not;

2. SA standard allows narrower visual field than M standard (Some SA
helmets may not be street legal);
3. SA standard has rollbar impact test while M standard does not.
4. The K standards are very similar to the SA standards, however the K
standards omit the requirements for flame retardency. 

Why replace the helmet every five years?

The five year replacement recommendation is based on a consensus by both the
helmet manufacturers and the Snell Foundation. Glues, resins and other
materials used in helmet production over time can affect liner materials. Hair
oils, body fluids and cosmetics, as well as normal "wear and tear" all contribute to
helmet degradation. Petroleum based products present in cleaners, paints, fuels
and other commonly encountered materials may also degrade materials used in
many helmets possibly degrading performance. Additionally, experience indicates
there will be a noticeable improvement in the protective characteristic of helmets
over a five year period due to advances in materials, designs, production methods
and the standards. Thus, the recommendation for five year helmet replacement is
a judgment call stemming from a prudent safety philosophy.

Where is the Snell label located?

There are two forms of the Snell serialized label.  The most common is the
adhesive label, but there is also a cloth type for the M, SA and RS standards. The
adhesive label, or decal is usually affixed somewhere on the inside of the helmet. 
If it is not readily visible, check underneath the flaps of the comfort padding. The
cloth type labels a generally sewn onto the chin strap and folded over.  If a
thorough search fails to turn up a decal then your helmet is not part of the Snell
certification program and does not have the confidence of the Foundation.
