What kind of oil are you using? If you are where it is cold (below 40`), most standard oil will run up to 90# of oil pressure, cold. I used to race a BMW/Chevron and the oil pressure relief valve would stick (100+) and the oil filter would expand and start to leak. I do not feel the L6 turbo pump will put out more than 90#. Once you get a little temp in your oil it will start to thin out and your pressure will run at 50-55#. Just keep it under 3000 when you first take off and it will be just fine. Your seals really do not have any oil pressure on them; Only crankcase pressure. I run Mobil 1 because of the lower viscosity charactoristics. If high cold pressure is a concern you may want to convert to a synthetic. (If the car has been rebuilt within the last 8-10 years)
