Timeline firms for Supercars transient dyno test

SUPERCARS is set to embark on another American voyage prior to this year’s Repco Bathurst 1000.

V8 Sleuth understands that the pieces are in place for what is shaping up to be an August trip to complete long-awaited transient dyno testing.

It’s hoped that such an expedition will put to bed any engine parity qualms, much like the off-season Windshear wind tunnel visit has done on the aero front.

There have been various factors which have delayed the official booking of a transient dyno test date, including an initial plan to upgrade and use a Melbourne facility before deciding in favour of heading to the AVL headquarters in Michigan.

Supercars general manager of motorsport Tim Edwards had furthermore indicated the need to refine both the Ford 5.4-litre and Chevrolet 5.7-litre units before starting the costly and complex process.

“What we’re trying to do is make sure that when we go, we have got all of the tools that we need and we’re totally ready,” Edwards said earlier this month on the Motorsport News Podcast.

“When there’s still bits of map adjustments and things like that going on, you want to make sure that you have got the engines as close as you can using the tools that we’ve already got at our disposal.

“What we don’t want to do is fly over to America and hop on an AVL dyno and start doing what I’d argue is some of the basics.”

Accordingly, there has been semi-regular engine testing which has often related to mapping.

The latest example was a Supercars-supervised program run on a Red Bull Ampol Camaro (raced last year by Broc Feeney) today at Queensland Raceway, which was seen to be a final chance to lock in software specifications.

Ford is said to have made strides with its Coyote since Dick Johnson Racing-owned Motorsport Powertrains took the reins of the Blue Oval’s Supercars engine efforts in the off-season.

Parity has been a non-topic at the past three Supercars rounds, although there were still some question marks around comparative engine performance at altitude during the season-opening Bathurst 500.

That makes it all the more important that the American transient dyno testing is completed prior to the category’s return to Mount Panorama for the Great Race in October.
