Triple Eight has replaced the Dick Johnson Racing-owned Motorsport Powertrains as the marque\u2019s engine supplier as part of the Red Bull-backed team\u2019s switch from General Motors.<\/p>\n
Minor changes to the 5.4-litre Coyote V8 have been implemented ahead of this weekend\u2019s season-opener in Sydney, but it\u2019s only the beginning as the Brisbane squad applies its trademark attention to detail.<\/p>\n
Team manager Mark Dutton told Speedcafe it\u2019s reliability and not the tightly-controlled performance aspects of the engine that are the main focus after various failures last year.<\/p>\n
\u201cThe drivers thought the base package was pretty good from the first time the drove it, so it\u2019s not miles away, but the reliability is a big focus for us,\u201d Dutton told Speedcafe.<\/p>\n
\u201cWe\u2019re in the understanding phase, really, and the testing phase, because everything\u2019s quite a long lead time to actually invoke change and know that you can prove something specifically cracks and things like that.<\/p>\n
\u201cThere\u2019s a few little tidy ups we\u2019ve done. They\u2019re not power gains, because you can\u2019t, there\u2019s the cap to control power, so you\u2019re not trying to change the power at all.<\/p>\n
\u201cBut there\u2019s just some tidy ups that you can do when you come in with fresh eyes, as we have.\u201d<\/p>\n
Will Brown fastest, slow start for Toyotas at Sydney test<\/a><\/p>\n<\/p>\n Triple Eight\u2019s new engine shop built within its existing Banyo headquarters has so far churned out eight new engines and undertaken half-life rebuilds on five more.<\/p>\n Minor upgrades such as shifting the orientation of the throttle body have been applied to existing engines at Sydney Motorsport Park by Triple Eight engine shop staff.<\/p>\n \u201cLittle things like that don\u2019t give you any more power, but it should give you a bit more balanced airflow through the manifold and things like that,\u201d said Dutton. \u201cThey\u2019re tidy ups.\u201d<\/p>\n Dutton is unsure when further upgrades will be ready to roll out, noting the lengthy process of analysis, testing and homologation that must take place.<\/p>\n A particular focus is understood to be on the crankshaft, on which cracking has been reported despite a last-minute emergency supplier change ahead of the 2024 Bathurst 1000.<\/p>\n \u201cWe\u2019re just starting the process of measuring, trying to understand, trying to put numbers to things so that you can make decisions based on those numbers,\u201d Dutton said.<\/p>\n \u201cYou can have all logic in the world and apply really good science and engineering, but if it\u2019s a factor that is unrelated to that, a chassis side factor, for example, you can tune up the engine side of things and still have the issue because it\u2019s coming from the chassis.<\/p>\n \u201cSo it\u2019s quite different to know for sure what the problem is, but we\u2019re going to give it a red hot crack.\u201d<\/p>\n Broc Feeney\u2019s #88 Red Bull Ampol Racing Ford Mustang at Bathurst..<\/p>\n![\"Broc](\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/02\/Bathurst12Hour-Supercars-027-copy.jpg\")
