Off the back of the controversy, Brad Jones gives insight into the size, location and role of the restrictors in his team’s latest YouTube video, above.
Triple Eight on Tuesday uncovered that it had a 49mm restrictor fitted to Brown’s car, rather than the stipulated 50mm.
Supercars said the 49mm restrictor was supplied solely for the purpose of running the car’s pre-season launch in Geelong and was never intended for race use.
The category had to have more Ford restrictors produced ahead of the opening round this year to accommodate the increased number of Mustangs in the field.
Supercars’ restrictors are typically colour coded to avoid confusion over sizes.
Jones showed off the 52mm anodised orange restrictor used in the Toyota and suggested a lack of colouring may have played a role in the Triple Eight saga.
“The Ford is anodised red and is a 50mm,” he said.
“The mix-up I think with Triple Eight is that some of the ones, because there’s more Fords in the series this year, early on weren’t anodised.”
Multiple sizes of Ford restrictor are in existence following changes to the specification of the Coyote V8 since Gen3 debuted.
Regardless, Jones said his team checks each restrictor when it is delivered by Supercars.
“When we get these, they’re made by Supercars, so they machine them up, they anodise them and they give them to you,” he said.
“They turn up here at BJR, we measure every single one and then we put them into the system.”
