The American GT Challenge Series was founded by competitor Woodson Duncan in 2004. The inaugural season consisted of seven events. The championship went down to the wire, with Puerto Rico’s Edison Lluch and Charlie Webster from Canada tied entering the final weekend. Lluch retired in the final race, which allowed Webster to secure the title.

The American Road Racing Association (AGT) Regulations are designed to ensure the orderly conduct of road racing events. The series is still a work in progress to have a preferred package based around a 358 cu.in. 12:1 compression motor. This will be instituted over time, allowing teams to compete with other engine combinations.

All Purpose built, tube frame chassis, V8 and V6, push rod, carbureted engine, composite bodied, replicas of series produced American touring or grand touring cars conforming to 2003 SCCA GT-1, 2003 Grand Am GTS or 2003 Trans-Am specifications and meeting the AGT adjusted weight minimums and wing heights are eligible to compete. Cars from other series will be considered. GT-1 cars must present their logbook showing technical and safety conformance or annual tech inspection sticker.

Vehicle weight is determined by engine displacement, cylinder head modifications, wheel width, and diameter. However, all cars must have a minimum ground clearance of 2 inches when measured, ready to race without the driver or fuel.

The hosting track will supply fuel. All AGT entrants must compete on Goodyear Racing Tires, the Official Tire of the American GT Challenge.

Race formats are either:

  • Multiple heats with a minimum length of 25-minutes, or
  • A single contest that is 50-minutes long

Championship points are awarded based on the number of competitors a driver beats.

Each marque, Ford, GM, and Chrysler will be awarded one point for a win and one point for a pole. The marque with the highest number of points at the end of the season will be declared the Manufacturers Champion.

Round three of the 2005 American GT Challenge Series was held at Mosport International Raceway. Drivers would compete in a thirty-minute qualifying and feature race around the ten-turn 2.459-mile road course.

The event only drew seven entries.

The opening lap for Sunday morning’s contest at Mosport International Raceway. Leading the field of American GT Challenge competitors is the pole-sitter, Joey Scarallo, driving the No. 06 Toyo Tires / ROH Wheels Chevrolet Corvette. Trailing Scarallo is the other front-row starter, Edison Lluch, in the No. 73 El Tuque / Don Q sponsored Chevrolet Corvette. Behind the leaders in the No. 95 CJ Webster of Canada Chevrolet Corvette is the third-place starter, Charlie Webster.
Former open-wheel competitor Joey Scarallo entered the American GT Challenge round at Mosport International Raceway with two years of SCCA Trans Am experience. The last time the Trans Am series raced at Mosport, Scarallo finished seventh. He put his track knowledge to good use and qualified on the pole. Despite pressure from Edison Lluch, Scarallo won race one. On Sunday afternoon, he collected his second flag-to-flag victory of the weekend.
Woodson Duncan is the founder of the American GT Challenge Series. Duncan competes in the No. 29 Sky Blue Racing Ford Mustang. He obtained his grand touring experience in the Grand-Am and Trans-Am series. Duncan was fourth fastest in qualifying for Sunday morning’s contest. Unfortunately, he was disqualified from the race. Duncan started at the back of the grid for the finale. Problems for Charlie Webster and Edison Lluch allowed him to finish second.
The favourite this weekend was local competitor Charlie Webster. Webster piloted his familiar No. 95 CJ Webster of Canada Chevrolet Corvette. He entered this year’s series as the inaugural American GT Challenge champion. Webster was gridded third for the weekend’s first contest. He could not maintain the pace set by the leaders, Joey Scarallo and Edison Lluch and finished third. In the afternoon, Webster earned another third-place result.
Last year, Edison Lluch battled Charlie Webster for the title and finished second. To redeem himself, Lluch won the opening round of 2005 at Carolina Motorsports Park. The No. 73 El Tuque / Don Q Chevrolet Corvette driver qualified second for Sunday morning’s contest at Mosport. He challenged the eventual winner, Joey Scarallo, but slowed down due to a power steering issue and finished second. A flat tire in race two resulted in a fourth-place finish.
