Walkinshaw TWG Racing\u2019s 1-3 finish was an emphatic way to shake-off lingering doubts over the reliability of the 2UR-GSE V8 engine.<\/p>\n
The Bend marked the second event following the rollout of a \u2018B-spec\u2019 aimed at ridding the engine of its valvetrain weakness.<\/p>\n
A long-awaited camshaft upgrade was introduced at Ipswich following extensive work between Walkinshaw and its UK-based engine partner Swindon Powertrains.<\/p>\n
Walkinshaw TWG team principal and Toyota project architect Carl Faux revealed to Speedcafe post-race that the Ryan Wood\/Jaxon Evans entry would not have finished had it still had an A-spec aboard.<\/p>\n
\u201cIt\u2019s great for Toyota, great for the team here,\u201d he said of the result.<\/p>\n
\u201cAll the hard work that\u2019s been put in over the last, I\u2019m not going to say over the last year, it\u2019s more than that culminating here.<\/p>\n
\u201cThe increased reliability of the valvetrain showed [on Sunday].<\/p>\n
\u201cWoody had a double downshift into Turn 1, a gearbox issue during the race, which pinged the engine.<\/p>\n
\u201cWe know that A-spec wouldn\u2019t have survived that, but B-spec has, so we\u2019re happy with that, and he could carry on.\u201d<\/p>\n
The B-spec motors were fitted to the cars on the Thursday of the Ipswich event following a rush to have them completed.<\/p>\n
An engine failure for Chaz Mostert on the Sunday of the Queensland round raised alarm bells, but turned out to be an unrelated problem that manifested itself as a bearing failure.<\/p>\n

According to Faux, there were no changes to the specifications of the engine following QR, and the four B-specs in service completed the whole of the race weekend at The Bend.<\/p>\n
Brad Jones Racing\u2019s Macauley Jones\/Jordan Boys entry had remained on the A-spec by choice in South Australia.<\/p>\n
The successful run at The Bend means there\u2019s currently no plan to do mid-weekend engine swaps at Bathurst.<\/p>\n
\u201cWe inspected all the B-specs on Saturday night and undertook the NDT (non-destructive testing) we do on them, and we were happy that they were able to continue,\u201d he said.<\/p>\n
\u201cWe\u2019ll do that inspection again [at Bathurst]. If there\u2019s anything that makes us think that we need to do preventative or precautionary, then we will.\u201d<\/p>\n
There were no precautions being taken in the wake of Sunday\u2019s victory, with Chaz Mostert\u2019s request to perform a post-race burnout approved by the boss himself \u2013 much to the driver\u2019s surprise.<\/p>\n
\u201cThe engine department will be upset with me because I said he could do a burnout\u2026\u201d Faux smiled.<\/p>\n
Faux is proud of the revised package but acknowledges there\u2019s no guarantees at Bathurst.<\/p>\n
\u201cWe had four engine failures across two cars when we were at Bathurst last time,\u201d he said. \u201cIf we do better than that this year, I\u2019ll be happy.\u201d<\/p>\n
Both of the team\u2019s Ford Mustangs were taken out of Great Race contention by engine trouble last year \u2013 Mostert stopping on track after dropping a cylinder and Wood forced to pit with a failed crank sensor.<\/p>\n
The Bathurst 1000 will be Faux\u2019s last event with the team, which he is electing to depart following a nine-year stint that has included two Great Race victories and the 2025 Supercars title.<\/p>\n
Sunday\u2019s result locked reigning champion Mostert into the Finals Series, while Wood is all-but assured of his place, pending a freakish set of circumstances playing out at Bathurst.<\/a><\/p>\n
