If the engine is ruled legal, the money will go to the torn down car for gaskets, etc. If the car is found to be illegal the money goes back to the one who filed the tear down and the illegal car looses all points,. awards and any records set for race date. Tracks themselves may tear down any car at any time for the same fee. Refusal of a tear down will result in the same penalties as being illegal all tear downs must be conducted indoors and be completed two hours after leaving pit area. If the car does not show it will be ruled as a refusal, and therefore illegal. In the case of a two day event, tear downs will only be conducted on the second day after the main event. Any drivers in the feature race can tear down any other driver of the feature race. There will be no backing out of a tear down by the challenging driver, if he or she backs out of a tear down, the $100 fee is forfeit and that driver will lose all points, awards and any records he or she won or set that weekend. If found illegal one tear down or refusal to be checked will result in a suspension for two race dates from date of infraction as well as loss of all track points year to date. All illegal parts become the property of the club and the illegal car will be fined $500. All illegal parts will become club property and will be auctioned off at season end.
