Mustangs to run 80mm throttle body from Sydney

Supercars has approved a Ford engine tweak which will come into effect at this weekend’s Beaurepaires Sydney SuperNight.

New Ford and Chevrolet engines were introduced to the Repco Supercars Championship with the introduction of Gen3 in 2023.

The new engines are of single rather than individual throttle body configuration.

Following the NTI Townsville 500, Ford’s Homologation Team, Dick Johnson Racing, tested with a new 80mm throttle body.

Following testing, results have been verified, with a change to the Ford Engine Specification Document (ESD) approved for Sydney.

It comes after aerodynamic tweaks were approved ahead of Townsville for the Ford Mustang.

"Supercars can confirm that the Ford Homologation Team requested an Engine Specification Document (ESD) change to use an 80mm throttle body," a Supercars spokesperson said.

"This has now been tested, verified, both on and off track, and is now approved for introduction for the Beaurepaires Sydney SuperNight.”

Supercars will hit the track for the first time on Saturday at Sydney Motorsport Park.

The Eastern Creek venue will host the very first night race of the Gen3 Ford vs Chevrolet era on Saturday night.

Coca-Cola Chevrolet Camaro driver Will Brown leads teammate Brodie Kostecki by seven points, with Red Bull Ampol Racing’s Broc Feeney 26 points down in third, defending Supercars Champion and Feeney’s teammate Shane van Gisbergen is fourth, 72 points behind Brown.
