TRACK TECH INSPECTION
GENERAL (602 CRATE ENGINE and OPEN ENGINE)
ted tech inspections are for the purpose of satisfying Chapman’s Can Am Motorsports Park
Officials only, and are in no way performed to prove anything to anyone else, including fellow competitors. If a
competing team is suspicious of a fellow competitor, this is what the protest procedure is intended for.
MIX OF OPEN AND 602 CRATE ENGINES FOR INSPECTION, most usually there are a mix of OPEN and
602 Crate engines in the top 5. Obviously, having different rules to go by, they may require separate inspection
ONE PERSON ALLOWED IN TECH AREA, only driver will be allowed in tech area, driver must remain with
car until otherwise instructed by official(s), a designated number of crew members will be allowed by tech
officials IF and WHEN needed, as decided by officials.
HOOD OPENING, car hood cannot be opened/removed until allowed by tech official.
THOROUGH INSPECTION, take warning, always be prepared for a thorough inspection of your car! This
could be in the form of a complete engine tear down! Failure to submit to any such demanded inspection will
result in severe penalties. Car and or driver can be demanded any such inspection upon arriving on Chapman’s
Can Am Motorsports Park premises. Before and or after any event, any position, including DNF & DNS.
Everything on car including driver must pass safety, as well as competition rules. Furthermore, in the event that
any car and or driver has been competing with a rule infraction in the past, regardless of the infraction or the
length of time will have no involvement with the tech decision if found not in compliance to these rules
concerning any tech inspection or protest situation.
INSPECTION ISSUE, in a track tech inspection situation if an issue should occur with obtaining utilizable
results, whether resulting from tool failure or any other non-intentional means, the inspection may be
terminated. Tech official will render the deciding factor in such an issue.
ANTI TAMPER SEALED AREA, no inspection will be done on any part/component within anti tamper sealed
REFUSE A TECH INSPECTION, driver only can refuse a tech inspection and will forfeit the affected event
money and points as well as ALL points accumulated at the affected track.
REGULAR CAR, n
ot being the driver’s regular car has no re
lationship to the procedure and or outcome
regarding any tech inspection. As the driver you are responsible for the car you are driving to be conforming to
Verbal and or physical action directed toward officials or other racers will not be tolerated. The driver is and
will be held accountable for any and all actions of his crew/owner, whether or not associated with car will be
determined by officials. Any such issues arise, driver/car will be subjected to loosing Tech Area privileges. In
the event of this the driver and car would be disqualified from the effected event, will lose all money and points
earned in the effected event. Further discretionary action may be imposed.
Questions/input will be addressed as possible by the officials.
Always remember, the need to report to tech area suggests a high degree of accomplishment. Finish off earning
your way to tech by being professional when you get there. If someone is badgering you, just remember, they
are upset because you did it better than them.
602 CRATE ENGINE ONLY
DYNO TECH INSPECTION POLICIES AND PROCEDURES:
SEALED AREAS, no inspections will be done within anti tamper seal areas.
RANDOM SELECTED, throughout the season race teams will be randomly selected for a dyno inspection. Try
not to look at this as being harassed or singled out. If you conform to the rules you have no reason to be
concerned or get upset about. Something to always remember, the need to report to tech area suggests a high
degree of accomplishment.
PULLING ENGINE, the team will be told to pull their finishing position engine. Engine pulling action must
begin as soon team is notified, and engine must be in the possession of Chapman’s Can Am Motorsports Park
within 1 hour.
REFUSE DYNO INSPECTION, driver only can refuse the dyno test inspection. Refusing the dyno test
inspection will result in the same penalties as found illegal, in the found illegal penalties section below.
FOUND ILLEGAL PENALTIES, any engine found to be illegal. The engine will be returned after the dyno test
and immediately be classified as OPEN engine status, and from then on not be allowed Crate engine
classification. Furthermore, engine must then conform to all OPEN engine specific rules.
Any tech inspection result on any specific car/driver and deemed legal or illegal will not affirm the car/driver
100% conforming with or against the rules as others may interpret it. Opinions are twisted to how each
individual is affected by the decision. Therefore, if a specific car/driver is deemed legal or illegal, then

decision. Any and all inspections offer no guarantee that anyone else may agree with the inspection decision.
Disagreeing with any judgment will have no effect on the decision.
