Showing no outright speed in the six practice sessions in the lead up to Sunday’s ‘Great Race’ which included an engine change, Red Bull Holden Racing Team are still yet to find answers to the broken valve in the engine.
The Whincup/Dumbrell suffered a loss in power on lap 119, running 13th, was looking set to a big points day when series leader McLaughlin had his on engine failure on lap 74.
The team already confirmed that car #88 engine failure was due to a broken valve the cause the car to run on seven cylinders but they want to find out how it happened to a brand new engine.
They did the engine on Saturday afternoon in their quest to fix the speed issues in the lead up to the race and an engine change was a key part in ensuring full reliability and performance from the engine.
“We had a couple of things that weren’t making sense on car #88 and we wanted to eliminate the possibility of it being the engine,” Cauchi said.
“We thought we’d change to the spare engine, which was a fresh engine so that there was no compromise from a reliability point of view.”
“So the engine change on Saturday didn’t compromise us in terms of the failure we saw on Sunday but it was something we did in trying to sort out some other issues going on with the car.”
“At the moment, we haven’t pulled the engine apart, but from what we’ve seen it looks like a valve has broken.”
“One cylinder wasn’t working so ultimately that was the end of our Bathurst campaign. We weren’t really expecting to see a valve issue so that came as a bit of a surprise.”
Even though Red Bull Holden Racing Team calls the Bathurst 1000 result for car 88, a blow to their championship campaign but they vow to keep pushing until the end to ensure the championship trophy remains in Brisbane.
“It’s disappointing we weren’t there, in the end, to fight it out for a potential win,” he said.
“It obviously has pretty massive championship implications with Bathurst being 300 points so there’s potential to gain or lose a huge amount of points, and unfortunately, we lost a huge amount of points.”
“We went into the race 84 points behind a car and now we’re 91 points behind a different car.”
“It doesn’t matter which car it is, we’re still behind, so we’ve got to work hard and fight hard to the very last race of the championship.
“The top three cars could win the championship but you just don’t know – there are probably others that could pop in as well so it’s certainly on for everyone.”
