First track experience today ! Some good, some really bad

Hey guys...

Thanks for clearing up my confusion on the oil cooler... makes sense that I was looking at the power steering cooler... glad it is there ! I blew up 2 power steering pumps on my boxster, so that's one less thing to worry about !

Also, thanks for the tip on the nismo oil cooler... I'll definitely look into that! May also be possible to build a better one with other parts - I'll let everyone know once I get that figured out. I'll prob skip the LSD cooler - figure I'll drive it till it dies then look for a mech LSD.

Appreciate the tip on the tires too, but I'm actually going to put them in storage and get a set of Enkeis + toyo R888s.

Regarding local shops... yes... my car will be the test mule for Vivid racing... they are doing intake + pulleys + exhaust under Agency Power... I'll start a separate thread on that with pics once it is underway... it'll be several weeks before I update... I'm also planning to do some other mods...

Another good shop for those in Phoenix is SRD... talked with their owner, Chet, at the track today and he's definitely interested in working on 370s, and has done some pretty cool 350 race car conversions in the past

So, going back to my original post... I'd still really like to get some confirmation about the root cause of my issues... am I right that it was the computer stepping in to keep the engine cool ? do you think the right way to address it is by adding an oil cooler ? THANKS

Hey Welcome to the forums. I think you're the first member to take their 370Z to the track in the US. Congrats.

Your problem is well known by the 370Z Tuners. Mines 370Z in Fuji Racetrack suffered the same problem! Here are more info on the Mine's 370Z

Mine's MotorSports 370Z (fairlady Z) hits Fuji Racetrack 12.08.08

Then here's another thread where Namir said that G37 is suffering from the same oil heating issues. Basically once the oil temp goes above 135C, engine cuts down RPMs to protect and prevent any damage to engine.

First potential problem?

Solution? you need to put an oil cooler in so that you can drive the car LONGER without oil temp going up. This doesn't solve the problem but it'll allow you a much longer track time before heating the oil to 135C
