E. TIMING, PENALTY, AND TEARDOWN RULES<\/p>\n\n\n\n

E1. Timing will begin as designated for each car whether or not the car is on the starting line. Starting times can be adjusted at the timer\u2019s discretion. If the timers recognize a beneficial savings in time, a lagging car may be sent out ahead of its designated time. Usually this will be discussed with the Directors ahead of time. Time will start for this car when it leaves the starting line.<\/p>\n\n\n\n

E2. * Each car will come to a complete stop before starting at the timer\u2019s direction.<\/p>\n\n\n\n

E3. Removal of head or pan while at stop (not under time) or on tour day, if tour day occurs during the endurance run, will impose a time penalty of 1 hour. Report this infraction to the directors immediately. Removal of head or pan under time must be reported to the directors at the first opportunity for replacement of seal.<\/p>\n\n\n\n

E4. Changing the carburetor imposes a time penalty of 15 minutes. Report the infraction to a director immediately. Replacement carburetor must meet the requirements stated in the Inspection Rules.<\/p>\n\n\n\n

E5. Disabled cars will receive slow time for each leg not completed.  Cars trailered on the last day are not eligible for prize money or trophies.<\/p>\n\n\n\n

E6. Replacement of complete engine is cause for disqualification.<\/p>\n\n\n\n

E7. All Directors are expected to attend the teardown. The top car will be torn down immediately following the last flag. Additional teardowns will be put to a vote of the Board of Directors. Directors will discuss and vote to accept or reject items of question.<\/p>\n\n\n\n

E8. The first-place car will be torn down by a panel of five inspectors. The driver in the top position at teardown cannot be an inspector, but the next five place drivers are required to be inspectors for teardown. If the first-place car is disqualified, the next place lower will be inspected, until a car has been found qualified. All inspectors must vote.  Any driver has the right to consult with an inspector on any issues concerning the cars.  The five teardown inspectors have final say in what is brought to the vote of the drivers.   <\/p>\n\n\n\n

E9. The Tear-Down Manual<\/a> is a supplement to printed Rules. If there is conflict then the printed Rules will take precedence.
