Engine tweaks coming for the Holden supercar team

Autosport has learned that a change in the homologation of the V8 built on the KRE race engine, an increase in the rocker ratio from 1.60 to 1.65, has been approved by the Supercar Commission.

KRE works closely with Triple Eight to provide engines for Red Bull-backed teams and customer teams such as Team 18.

Brad Jones Racing also runs KRE power in four entries.

According to a supercar spokesperson, this change causes the KRE motor to match the Ford unit used in the Mustang, with no change to the maximum power limit.

“The 1.65 locker now available to Ford Engine Builder is now available to GM Engine Builder,” read the statement provided to Autosport.

“All engines must still comply with maximum total engine power, regardless of which rocker is applied.”

It is currently unknown when the updated KRE engine package will debut. Triple Eight has confirmed that changes will only be made if the required parts are available on all KRE engines in the field.

Walkinshaw Racing is another GM engine supplier in the field, powering Walkinshaw Andretti United and Erebus Motorsport Commodores.

Based on that statement, WR is also eligible to apply for the same changes if possible without breaking AEP.

Engine rules have recently been in the news after the Jordan Boys were stripped of their first Super 2 race win.

His Image Racing Holden WR motor failed a post-race check due to a cylinder head that didn’t match the engine specs.

WR argued that it had the blessing that supercars would fit in the head as a short-term solution to inventory shortages.

Supercar reopens all Bathurst 1000 campgrounds

The supercar will back up and operate all eight campgrounds for this year’s Bathurst 1000.

The Australian series has confirmed that the complete suite of campsites will open for the October Classic for the first time since 2019.

The move follows the complete closure of the Great Race camp facility last year due to the strict coronavirus protocol, but only four sites opened at the Mount Panorama 500 in February, which opened in the 2021 season.

It also suggests that the event may return to near full capacity, subject to the outbreak of the associated virus.

Currently, the surrounding sports stadiums are beginning to abolish the capacity rule, and major soccer codes are now welcoming most capacity spectators in the country.

According to the supercar, campsite ticket holders from 2019 will have access to pre-sale starting next week before general sale on June 15th.

“The supercar is happy to see that all eight campgrounds will open at Mount Panorama for the 2021 Repco Bathurst 1000,” read a statement in the series.

“Paddock, McPhilamie Park, Reed and Sulman, Max Cameron, Chase, Orchard, Enduro and Motorhomes will be running for this year’s event from October 7th to 10th.

“People who camp in 2019 and choose not to renew at the 2020 event or receive a refund for the 2020 renewal will be eligible for the next Tuesday, April 20th (2pm AEST) to Friday 2021. You have the right to refuse the campsite first at the event of the year. May 21st (11:59 pm AEST).

“Campgrounds not purchased during the renewal period will be open to the public at 2:00 pm AEST on Tuesday, June 15th.”

Supercars have begun to lift the last restrictions, such as opening the paddock to fans at Mount Panorama 500.

However, at the direction of the Victoria State Government, the Sundown Round had protracted restrictions. Engine tweaks coming for the Holden supercar team
