At this SCCA Time Trial event in our 2023 BRZ shop car, Amy put in 4 solid sessions and netted her bast lap in session 3 here, when it was 98F ambient and 127F track temps.
At this event we had just added a CSF aluminum radiator, but otherwise it was a completely stock drivetrain. MCS remote doubles and 18x10" wheels / 265mm Yokohama A052 tires, and Amy was driving all 4 sessions solo, while Terry drove his car in his sessions - for the first time, no sharing! It was a very hot day and eventually got up to 107F, so the 4th sessions times were not an improvement.
Amy set her Personal Best in this car for this track, and as you will see she did it going 3 wide out of Big Bend, lifting throttle and almost dropping two wheels in the dirt. A couple of competitors ahead of her did not have... the best situational awareness and that cost her some time here - she might have won her class if she didn't have to lift right before the finish line. She took another 2 laps but the tires got too hot, the car slowed down, and she came into the pits.
This video is also the first time we have utilized CAN data (the stock BRZ data) and external sensors (AEM oil pressure gauge) and overlaid that over the Garmin Catalyst video/data. We worked on this format and will go back and merge data from 2 previous events the same way.
We did this AEM oil pressure gauge to show if the factory FA24 engine has some sort of terminal oil pressure issue. From this video.... not really seeing that. Yes, the oil pressure drops as it gets hot (we saw a peak of 253F oil temps and will move from 5W30 to 5W40 Motul 8100 before the next event, and likely to an oil cooler after that) and you can see this at the top left "oil pressure vs time" chart, as well as the peak hi/low pressures for each corner just underneath.
Soon we will stitch together several video clips with this AEM oil pressure data and see if any patterns emerge. Stay tuned! #ShareTheData
