Victorian V8 Supercars teams believe Triple Eight Race Engineering used a rival team to secretly collect data for its powerhouse Brisbane outfit in a masterstroke that has ruined the Winton home-track advantage.
Teams that test at Winton Raceway, including Prodrive Racing Australia (PRA) and the Holden Racing Team (HRT), were expected to dominate at the north-east Victorian track this weekend with two track test days allowing them to get an early read on the resurfaced track.
But Triple Eight owner Rolland Dane robbed them of a potentially race winning advantage by sending Jamie Whincup and his engineer into enemy territory last month to drive Lee Holdsworth's Victorian-based car under the guise of helping the satellite team, owned by Charlie Schwerkolt.
Triple Eight is based in Queensland and tests at the Queensland Raceway.
"No we won't have any advantage," said a Triple Eight rival.
