Re: Engine cooling next step after 3rd rad. larger oil cooler or deep sump
There are two ways to reduce the oil temps, first is a GT3 oil/water exchanger. This exchanger doubles the capacity of the oil being cooled within the exchanger. LN also sells their own brand of oil/water exchanger for your car. This reduces you oil temps about 10 degrees, not a big reduction but useful.
The second is the LN option of a deeper sump that is intended to help cool the oil as well as add more volume. Check out the LN web site for details. djm68, who runs a R Cayman, says this deep sump reduced his oil temperature 15 degrees using same ambient temperatures before and after install.
Lastly, regarding Mobil 1 0W-40, please use the FS brand, not the european brand. Look up the web site RAT/540 and check where these two Mobil 1 oils end up as far as oil temperature thermal breakdown, and load carring capacity/film strength. Mobil 1 FS 0W-40 came in #6 in load carring/film strength and very good in thermal breakdown starting at 280 degrees F. You can buy this oil on line for cheap so change it often while tracking your car.
