Would you happen to know what sustained gee's are on your fast laps? Or have an export (vbo if possible) of the data? Not sure if you've come across this thread where we have been discussing oil pressure drops during cornering, but your car would be a great candidate since it's on much higher grip tires than other cars that have posted data. Even more so since you are doing and plan to continue to do UOA. |
FYI, I use 818GT BT GPS transponder - the only one I've used that doesn't mess up this data.
Took a look at data on BRZ and C7 Z06.
Top is BRZ, bottom is Z06. I presume the most important corners where you might have this issue is long sweepers where the engine doesn't get to recover from it in a long time, so that would be the carousel at this local track. Corvette is pretty consistent, topping around 1.39G, while BRZ is a bit more wavy (when graph is at same scale), topping at 1.27G or so.
Top is BRZ, bottom is Z06. This is where BRZ peaked at around 1.6G. C7 also peaks at around 1.60-1.65G actually, but it was at a different corner. I think I probably slided the rear of the BRZ, and it generated that high G for a short instance when the rear finally 'settled' : ) The average Gs look similar.
Going back to your question, I think the Gs that we should care about is at 1.4G or so in my experience, at least at this track. Focus on long sweepers, and the engines are usually more vulnerable in one direction as well (left sweeper like GM V8s, or right sweepers, or both?). EDIT: just checked on that thread, and looks like there were issues at quick sweepers? Himm perhaps we should put in a baffle (if pickup is having hard time sucking oil). That's probably oil sloshing around in the pan, and not necessarily tied as much to high Gs in a way..
