But if you dont plan on tracking, a 19 or 25 row should be fine. maybe a 25 row with a thermostatic plate since your down in TX.

I'd love to get one as well. I want to track the car maybe once or twice a year, which is minimal but I live in Southwest FL and I have Stillen G3. I'm thinking a 25 row.....

HOWEVER........many 370z owners downshift and/or shift at a high RPM hiting 4-5k almost every shift ( I dont know why but its gonna kill the engine). If you're planning on shifting under 4k and not downshift, I can guarantee you YOU DO NOT NEED OIL COOLER.

If you're one of those obnoxious driver (always having your engine in high RPM, downshifting for no reason), then get the oil cooler

And of course install a oil cooler if you're gonna plan on tracking your car.

If I do not intend on bringing my 370z to the track should I still invest in an oil cooler?

I intend on buying headers, high flow cats , intake, cat back and a tune for the car over the next year. SHould I budget an oil cooler too?

GM used to put a plate/fin style oil cooler in the Z06. They no-longer do. The ZR1 doesn't have one, either.

Oil coolers cause problems on the street. Now GM has an oil-cooler that uses the coolant to regulate oil temp. It lives by the oil-pan and has no fins, etc. It simply moves the coolant and oil near each other to keep them roughly the same temp.

A lot of Z06 owners from previous years are only hitting 135-155* on the highway oil-temp. My car runs 185-200* on the highway, depending on ambient temp.

So MUCH BETTER for the car.

I would suggest you take a note from GM who REMOVED an oil-cooler like the one you want to install and developed a different one that won't cause as much issue.

Ok, let me put this more on your level.

Plate cooler gets oil too cold.
Manufacturer got rid of plate system and spent time/money to develop a cooler that would not make oil cold.
If oil not too hot, don't make oil too cold because of imagined problem.
Learn from big corporation. When big company spend money, usually viewed as a necessity.

Better?

220+ degree oil temps in a Z is not healthy for an engine, IMO. From an engineering standpoint it might be fine. Either way, I DONT GIVE A F*** about GMs experiences with oil coolers on Vettes.

This is because the ECM response to the A/C on by turning on the hi-speed cooling fans. It moves more air in the engine bay/through the radiator which cools the coolant which in turn will lower oil temps a bit.

I simply posted that little-known information as a way of showing you how much issue a plate-style cooler can cause that a corporation as large as GM, after implementing it on a car for half a decade, would spend the time and money to get rid of it. That's all.

You can of course install a thermostat or buy a plate cooler with a thermostat in it, but the point remains that you are doing this because in your mind 220* oil temps are too hot.

So your suggestion is for us to not use oil coolers because GM doesn't, and come up with a custom system similar to what GM uses. Great, we'll get right on that.

Right, you didnt exactly say "design a better system" you just said "dont run a system that has some drawbracks, even though there is no alternative."

220 oil temp is safe yes, but i easily saw 240+ on the street here in NY. While the temperatures wont damage the engine, they certainly resulted in noticeable performance loss, not to mention the fact that the oil itself will thin out and wear down faster at those temperatures.

Originally Posted by Dark Sarcasm (Post 1079703)

maybe, but installing an oil cooler to keep temps at 200 is fine also



no, its not incedental, you placed GM into this thread as if no one should use oil coolers b/c of GMs crap.



^ NOW THAT ^ would be a great post that brings a good technical point to the thread. And yet it had nothing to do with Corvette ********.



ok

Oil gets well over 300* in the engine at certain points in its cycle. 240* in the pan isn't going to kill it. Yes, it will break down a touch faster, but with a good oil that shouldn't be an issue. It's well within the oil's designed operating parameters.

On the flip side, if you put a cooler in there, during the rest of your normal driving the oil might well be 150-170* and not protect nearly as well as it is thicker, has more resistance to flow, hurts fuel economy, and is not up to it's designed operating point.

There is a reason GM went to the trouble of preventing their cars from running around with mid 100* oil-temps.

You can turn this into a brand-war all you want. I really don't care. I provided you with a real-world example of a manufacturer changing production 5-years in, and spending money to do it. You want to make it a pissing contest? Have at it. Everyone else can take the point as it was meant.



THAT is who my post was aimed at. The OP.

If you track your Z, by all means, I think it should have an oil-cooler. One with a bypass and thermostat.

If you don't track it, and aren't hitting limp mode, don't get one.

My posts in this thread have been about people who want an oil-cooler "just because they think...". Not people who actually tap the limp-mode.

-------

As to GM and their engineers, there is a reason Ferrari and a lot of others pay GM royalties for the technologies they have developed. Say whatever you want, but Nissan had to rent their engine technology from Ford. Ferrari gets their active suspension from GM, and lots of others barrow from elsewhere.

Your "follow GM" solution holds no value here, GM did not just remove the cooler, they designed the engine in a way to keep oil temps inline. For those of us that dont want our oil temperatures in a range where it affects performance and breaks down oil faster, all we can do is run oil coolers with a thermostatic plate.
