I would check out the GT3 997 oil/water exchanger and a 3rd radiator. A LN deep sump should take about 10 degrees out of the total. The GT3 oil/water exchanger will take out another 10 degrees. This info is on P9 from a year ago. Use your google search engine to find the link on P9. You may have some fitment issues with the GT3 exchanger as its taller than your OEM one, but keep in mind its capacity is more than triple your oem one. Call LN for more info.

It looks like oil temps are slightly high, but routinely I see temps above 230 even 240 during hard driving in a race. Strangely, I've had issues with the MAF cutting power. At the same time, temps seem to rise and give the illusion that the power cut is due to something with engine / oil temps. Does the power seem to come back above around 3,800 RPM? If so, you might have a bad MAF sensor causing the issue. When it happens, there is NO power down low.
