Claiming to know three people with blown engines from track use personally, 900BRZ states that they were all meticulous owners who use the correct oil and do not mistreat their cars. Instead of just taking their word for the supposed issues, the YouTuber sought concrete data-driven evidence to see if these cars have an inherent flaw.
With the help of oil pressure sensors in two locations and an Aim Solo2 data logger, the group of enthusiasts was able to track oil pressures in realtime on track. Instead of relying on a single car, they benchmarked a 2022 BRZ against a 2022 GR86 and a 2017 BRZ with the Performance Package, using multiple drivers in back-to-back testing around Thunderhill Raceway Park. Notably, the 2022 GR86 has had RTV sealant cleared from the oil pan.
Traditionally, oil pressure has a strong correlation with engine revs, as high engine speeds mean a greater need for proper lubrication. However, the group discovered a significant dip in oil pressure at high RPM and under wide-open throttle (WOT).
