So, now that we finally have confirmation on the style of cooler to be offered on the Z, I want to offer up some thoughts. There is going to be a lot of bickering on both sides before long I am sure, but based on my experience with the handful of cars I've owned, here are some thoughts.

The Oil-to-water cooler will probably NOT be sufficient for serious track use. On the other hand, guys that don't have much experience out there will probably find it perfectly suitable. We will almost certainly have water temps as the concern now, rather than oil temps. I am curious to see if Nissan adjusts limp mode, as hitting 280* oil temps on a water cooled system would generate huge problems....

On the other hand, it is absolutely excellent for most users. You get great daily-driveability, nice warm oil, and none of the (HUGE) risk that an air-cooled system generates. Apologies to those doing this, but it's absolutely an awful decision to run an air-cooled system without a pressure gauge. The risk of catastrophic engine failure from a fitting issue or a rock is huge, and definitely not worth it. The water-cooled system will only result in a coolant leak in the same situation--not really a big deal. Another nice perk is upgrading a radiator can help, and is not nearly as much a warranty concern as an air-to-oil cooler.
Water cooled systems are going to tend to be more consistent in controlling temps...which lets you keep the oil in the optimal range.

It remains to be seen what other changes have been made to the system-- I am interested to see for sure whether this system just taps straight into the old radiator setup, or if they have changed anything else...regardless, this marks a huge step forward for Z drivers. Truly a shame Nissan didn't pony up the extra $30 a unit to put this on from the start...would have been a lot better for everyone.

sorry didn't see your post.

780 for that?! :icon17: hahaha!

So the aftermarket coolers that everyone has now are air-to-oil coolers, correct?

:iagree: someone with an air cooled oil cooler mentioned something like his oil temp was steady at 180F on the street.

i'd like to be in 220 range (100C or higher) to rid moisture...

Yes

So if Nissan does adjust the limp mode, then would that make it more difficult to retrofit this oil to water cooler?

do we hear from people in the middle east (where this unit appears to be standard for their region) complaining about limp mode from high oil temp? :confused:

I haven't seen any of that crew tracking their cars

i can almost see some idiot putting heatsinks on his oil filter and call it an oil cooler. :icon17: does kalecoauto.com sell it?

Gonna do some math when I get back tonight.


Curious if anyone has any numbers for heat dissipation off the rad as it sits, or Max dissipation?

Z1 may have some data as they were testing the OEM rad v. the CSF rad to build some logs to promote the CSF rad, I never got the data.

I will get in touch and see what they've got.

why?

I'm thinking its cause you will be passing your coolant which is suppose to be cooling your engine threw a cooler that has 280 degree oil flowing in it.
