Well with the oil cooler and Nismo thermostat installed i had heat issues for the first time this weekend. My car is NA , and never had issues till this past weekend. First time attack session my needle was at 7/8 when i took the flag after 3 laps, second session my needle was just as 3/4 when i took the flag. Past weekend on that track have been hotter , and my temp never went past 1//2.

Well i have 2 guages laying around in the garage, time for a pod and mounting. I guess an oil temp guage and water temp will be great. Just need the adapters to run them.

Possibly, when I opened the oil cap I could see the smoke coming out through the valve cover, could it be oil burning producing white smoke? No one I've been to the track with has ever noticed smoke coming out of my exhaust though, just from the engine. The oil was fresh and coolant had been changed recently ![dunno](https://my350z.com/forum/images/smilies/dunno.gif)

I also forgot , my cats are installed, the first time i have ever run with cats on the track. They can cause extra heat , don't really know how much.
Anyone know?

Wow, white smoke out of the valve cover seems to mean you are probably overheating your oil and burning it off. Check the oil, its probably broken down and not doing a good job of lubricating. If I'm right you probably got really lucky you stopped when you did. I can't imagine that would happen below 300 F (oil temp).

Picked up the car yesterday from Driving Ambition here in Sac.
GTM oil cooler is now installed and ready for track duty! It will have its first real test at Thunderhill on Oct 16.
An interesting tidbit... I was talking Oil w/ Shad Huntley @ Driving Ambition. He was telling me that they've done Used Oil Analysis's (sp.) coming out of their psuedo famous red NSX that won SCCA Pro SP class this season. He was telling me they run Motul exclusively in the car now. It naturally runs at a lower temperature (good for our Zs) and is the only oil they've tried that doesn't completely breakdown. I was surprised to learn the Redline Oil they were using was completely breaking down under race conditions and leading to problems with heat and gumming up passages.
I think I'll be running Motul from now on too.

By chance are the sponsored by Motul? I ran the oil from all of my racecars over the years through regular analysis and never got a report back that the oil had "broken down." The additive package eventually goes away and the oil itself usually becomes contaminated with fuel and other combustion byproducts but it doesn't become something other then oil.
FYI... I've used Castrol, Mobil 1, Redline, Motul, Swepco, and Silkolene in 1/2 hour, 3 hour, and 6 hour races. None have ever turned into gum, sludge, clogged passages, or contributed to an oil related failure.

You cannot compare oil analysis from one type of engine to another. The result of the test is driven by alot of things - not all of which are properties of the oil itself. Instead, they are more the results of the interaction between that engine and that oil. In other words, if an engine builder uses bearing brand A, and sets his engine with a particular set of tolerances, then that oil is going to exhibit some properties after a test that another brand of engine using that same oil may not show. If one car is forced induction and another is not , again, that can show up in the test results. The point of the oil analysis is to try a sample of stuff from a bunch of brands, one one engine, change them at the same intervals using the same filter, take those results, and find what oil your particular engine gets along best with. Taking someone else's word for it when they don't even have your engine, is like buying a Buick because Tiger does their commercials.
Motul makes fine oil - hell we sell it and I've used it myself on some cars that we own. But beta is right - I'd love to see an example of an oil that did "break down" (I'm not sure what that means either), on that particular car as well.

I notice that the GTM, Stillen and other kits I've seen use -8AN fittings and hoses. I was going to piece together a kit using -10AN fittings and hoses just to be on the safe side.
-Could the -8AN sizing be contributing to the increase in oil pressures people are seeing?
-Is piecing together a kit with -10AN fittings an overkill?

As far as I can tell, everyone there at DA is straight shooters. They are just trying to do what is best for their race car and passing along the info to their customers. I can tell you that their UOA's come from Blackstone Labs. I've ordered a kit from their for myself just for curiousity sake.
