a few data points tracking E90 335i n54 6MT sedan in ~80F ambient on Pacific Raceways:
- I run ancient JB3 in map3, sometimes 92 octane, sometimes 93 (by adding 2 gallons of 100 octane)
- My peak straight speeds are ~120-130 mph, not going after records there since I run stock sport package brake disks with carbotech x10 pads
- my oil temps peak at 280F without loss of performance (knock on wood)
- oil temps seem to be the same with stock 15 years old oil cooler AND upgraded CSF cooler (surprise for me..)
- no idea on coolant temps so far
- comparable peak temps on stock car vs bolt ons (DPs, 7" FMIC, hot side piping and charge pipe) on the same JB3 tune
- I can speculate (no data to prove) that ~5 seconds improvement in lap time resulted in about 10F increase in peak oil temps, at least from ~270F to 280F, or it could be warmer/wetter/drier days
PS: hope knocking on wood helps
