Based on this chart I can't see any reason to get the oil temperature gauge over 195 F. and wouldn't want to see a gauge temp of 230. |
Good luck finding a car that only has an oil temp of 194 during 20 min at full pace on track ! In the real world I was able to limit my oil temps to the 240's even on hot 80 plus southern humidity conditions making 500plus hp with a 34 row setrab oil cooler. With the proper oil that is acceptable and my 40k track miles confirms that . Bearings in stock form are too narrow on the S54 and you will have wear at any temp , even on the street . That's why I went with the Lang racing widened bearing setup after my vibration damper failed and I was tearing down to look for bearing wear anyway .
