TRANSPORTATION

ENGINES: Participants are responsible for coordinating and funding their engine transportation to and from the Engine Masters Challenge dyno sites. At the conclusion of the initial dyno competition, PRIMEDIA will (at PRIMEDIA's expense) seal, crate and ship the 10 top engines to the final dyno competition site in Southern California. At the conclusion of the final dyno competition, the 10 finalists will be responsible for coordinating and funding their own engine transportation from the final dyno site to their home location.

PARTICIPANTS: Participants are responsible for their own transportation, lodging and food expenses that may be incurred while attending the Engine Masters Challenge dyno events.

DYNO SITES:

  • Assigned dyno times are actual "start-up" times. Contestants and/or their engines must arrive at least three hours prior to their assigned dyno time to ensure that all engines are properly prepared and loaded on the dyno. Contestants with early morning dyno times should deliver their engines on the previous afternoon to ensure that we maintain our published schedule.
  • Contestants who are not planning to be present during their dyno session should contact Michael Simpson immediately to make proper arrangements for their engine.
  • Contestants are not required to be present during the entire four days of competition.
  • Primedia will post the latest performance rankings as each dyno session is completed.
  • Contestants that are qualified for the Finals may not remove their engine from the dyno facility.
  • Contestants that fail to qualify for the Finals or are bumped out of qualification may remove their engine from the dyno facility at that time.
  • The Final Dyno Competition will be held on October 30th, 31st, and November 1st at the Westech facility in Southern California.

DYNO PULLS

Engine performance rankings will be determined using SuperFlow WinDyn software calculating all data, both torque and horsepower, under the curves then averaged together. Each sample will range from a minimum RPM of 2,500 to maximum RPM of 6,500. Tuning and/or mechanical adjustments on the engine are acceptable prior to the engine being connected to the dyno, tuning and/or mechanical adjustments will not be allowed after the engine has been connected to the dyno. The two highest performing engines from each of the three dyno locations will be selected to compete in the Final Dyno Competition event, in addition to the 4 highest performing engines not previously selected. A total of 10 engines will compete in the Final Dyno Competition.

RULES ENFORCEMENT

TEARDOWNS: PRIMEDIA reserves the right to tear down any engine for a rules enforcement inspection. PRIMEDIA personnel will conduct and supervise all teardowns. All winning engines will be torn down for rules enforcement inspection and contingency sponsor verification. Any participant found to be in violation of the rules or refusing to comply with an inspection request will be disqualified from the contest. It is the responsibility each Engine Masters Challenge contestant to verify the legality of any questionable part or component they have selected to use on their engine prior to the dyno competition.
