Autosport has learned that a change in the homologation of the V8s built by KRE Race Engines, an increase in the rocking ratio from 1.60 to 1.65, has been approved by the Supercars Commission.
KRE is closely associated with Triple Eight and supplies engines for the team supported by Red Bull and its customer groups such as Team 18.
Brad Jones Racing also operates KRE Power for its four entries.
According to a Supercars spokesman, the change will bring the KRE engines in line with the Ford units used in the Mustangs and there will be no change to the maximum power limit.
“The 1.65 rocker that was made available to the Ford engine manufacturers was also made available to the GM engine manufacturers,” it said in a statement to Autosport.
“All motors still have to meet the maximum total output of the motor, regardless of which rocker is used.”
It is currently unclear when the updated KRE engine package will make its debut. Triple Eight confirmed that the change will only be made if the required parts for all KRE engines are available in the field.
Walkinshaw Racing is the other GM engine supplier in the field that powers the Commodores Walkinshaw Andretti United and Erebus Motorsport.
Based on this statement, WR would also be entitled to request the same change if it were able to do so without breaking the AEP.
The engine rules recently hit the news after Jordan Boys lost their first Super2 race win.
The WR built engine in its Image Racing Holden failed post race test due to cylinder heads not in accordance with the engine specification document.
WR countered that it had the blessing of supercars to mount the heads as a short-term solution to a shortage of inventory.
Supercars is reopening all Bathurst 1000 campsites
At Supercars, all eight campsites will be back in operation for this year’s Bathurst 1000.
The Aussie series confirmed that the entire range of campsites will be open for the October Classic for the first time since 2019.
The move came after camping facilities were completely closed for last year’s Great Race due to strict coronavirus protocols, while only four of the Mount Panorama 500 locations were open for the 2021 season opening in February.
It is also advised that subject to relevant outbreaks of the virus, the event could be back to near full capacity.
Sports stadiums around the country have recently started lowering capacity rules. Major football codes are now welcoming most viewers across the country at full capacity.
According to Supercars, starting in 2019, camping card holders will have access to a pre-sale starting next week before general sales begin on June 15th.
“Supercars is pleased to confirm that all eight campsites on Mount Panorama are open for the Repco Bathurst 1000 2021,” read a statement from the series.
“The Paddock, McPhillamy Park, Reid and Sulman, Max Cameron, The Chase, The Orchard, Enduro and The Motorhome will be operational for this year’s event from October 7th to 10th.
“For those who camped in 2019 and have either decided not to extend the 2020 event or receive a refund for the 2020 extension, they have the first right of refusal for Campsites at the 2021 event May 21 (11:59 p.m. AEST).
“All campsites that were not purchased during the renewal period will be sold to the public on Tuesday, June 15 at 2:00 p.m. CEST.”
Supercars began lifting the final restrictions on Mount Panorama 500, including opening the paddock to fans.
However, there were ongoing restrictions on the Sandown Round by order of the Victorian state government.
