Are you kidding me???? Automakers don't tune their cars around how they think people drive them? Have you never heard of the sports car segment?my oil cooler is 1/3rd the size/capacity of the oem cooler and with zero airflow going to it (why? because I do not want to overcool it)
I am also making almost double stock non rs boost levels (16+ with little taper like most).
I also have so much random crap in front of my HE and radiator it doesn't get much airflow either.
People drive their car however they like and if someone drives it harder good for them, but the manufactures are not designing the car with the intent of it being driving how I do I can guarantee that. I have stress tested the car plenty was my entire point, but then I also referenced a thread of several other individuals having over cooling issues. So not just my personal account, and then the following post in this thread another user essentially repeated my sentiments with his personal account.
My car was stock at one point, and several stages there after, It did not start out with every mod on day one... However I have had oil and coolant temps monitored since day one with my scangauge and then later JB4. Obviously FBO + JB4 at +7psi map 6 (with little taper) is going to generate a lot more heat over stock, any car car would though. However stock is a different story.
I said 70F+ (not 70F tops) which is still substantially higher than the average temperature year round in any state. Obviously I've seen much higher temps than just 70F hence the + at the end.
but again heat soak in the intercooler system is entirely different than oil and coolant temps. Which this entire thing has been about oil temps and oil weights.
What relevance does heat exchanger temps have to do? you think even high 150F (much higher than I've sever seen) intercooler fluid temps are heat soaking warmer 190F oil temps? how is something colder warming up something hotter?
I never argued anything about the intercooler/heat exchanger not heat soaking. How is that related to the oil temps though... which is the entire context of this argument/discussion?
Heat exchanger/intercooler is a different completely unrelated story that has little to nothing to do with oil temps, or oil weights.
Sure obviously the heat exchanger has heat soak 100% agreed, but has nothing to do with oil though.
So I have no idea why you brought up heat exchanger heat soak in the first place.
The oil and coolant temps in this car run on the colder side. period. the end.
Cars are designed with the understanding of how customers treat them and is 100% taken into consideration during the design phase.
You don't build a class leading twin turbo 6 Cylinder engine with massive tuning potential, put it in a sports car chassis and then expect everyone to putt around like old people.
An Oil cooler 1/3 the size of your own when the 2017 Premium and Lux models didn't get one according to InfinitiParts??? And even if the site is wrong (Which is possible) It also flies in the face of all logic for Infiniti to include a oil cooler if these oil temps really don't run that hot it would simply be adding cost/complexity to install a cooler of that size if one that is 1/3 the size/capacity was capable of getting the job done!
Infiniti would have instead used a smaller one or dropped it all-together and probably recommended 5W30 as the base oil because it would have had similar viscosity
and run at slightly higher temperatures to achieve the same efficiency.
Yes you said 70F+..... Which means the range could be anywhere from 71F to 9,000F, you also said " I do this on a frequent basis even in 70F+ weather. " which
in the context of the sentence would imply 70F is a notably higher temperature then what you usually deal with and because I'm pretty sure you don't drive on
the surface of the Sun.
If your going to throw around numbers at least be clear what range your operating within, and while yes this thread in general has been about oil weights we have never been talking about oil temps specifically but in broader terms... So if the VR30 needs to pull power in order to compensate for higher temperatures it BY DEFEINTION RUNS HOT because whatever
cooling system is responsible for it isn't able to compensate.
That is why I continue to bring up the Heat Exchangers it is the single biggest limiting factor in the VR30 cooling system. The longevity and how a car performs
is determined by more than just the oil temperature.
