My old Altima registered 130 back in 2010 when I went to Death Valley in July (BAD IDEA) Well, we were more stopping by it since it was on our way to Vegas, but man was it scorching. On the plus side, I don't remember seeing any cops out there so if you hit it up in the cooler months could be a good time.

I would love to but there seems to be a problem with inspections here in Mass that are able to detect Uprev tuned cars even if they dont have stuff/mods that would fail on them:shakes head: I posted it here and got totally slammed by people thinking I had some agenda and nothing could be further from the truth.
Oh well I guess I will just wait, and so much for 1 click above 220....

how about an oil cooler? that's not really a performance mod, more of a safety/mechanical maintenance accessory

i suppose a oil cooler is a performance mod cause you can run your engine a lot harder in the same conditions.

ive not seen my oil temp go up that high. 225F is about where i max out even with spirited driving. but my area only goes up to about 95F max..

is it possible to run an inside cab switch to be able to turn the fans on and off and still let the car turn on the fans with a switch hooked up ? i know a guy that did this to an eclipse and it worked great.thoughts ?

Please tell me that's because you have an oil cooler installed. Because mine goes up to 260 on a couple choice backroads here in 80 degree weather and it's reached 270 on the Tail of the Dragon.

210 is the highest it ever got (stock oil cooler on 2012). thats in 98 degree temps and normal / spirited driving. guess it works, but when its that high it is slightly noticable. the low end power loss i mean. it usually runs at a steady 190

oil cooler is definitely in my z's future.87 here today.got on it form second.took it to 130 which was rather quick getting there.oil temp went from 210 to about 230-235.i didnt notice any power loss though so idk bout that.oil cooler is a must on this car unless you are going to drive it like grandpa lol.

take the long rear weather stripping off. snap-off the plastic bracket in the middle that covers the windshield wiper. screw in a oil pan cooler underneath the plastic shroud. Doing this I'm now commonly at 210 cruising on the highway instead of 220 and it also take longer for the engine oil to reach 210F. I'm betting that removing the engine cover will help with cooling. A couple free tweaks that do provide better cooling for free - the oil pan cooler is a trailer side vent that costs 10 bucks. credit given to Modshack and his DIY. Also a Uprev tune will help out a bit but I also find it takes slightly longer for the car to warm up now - could be the test pipes not holding heat like the stock cats though. Of course an oil cooler is the better albeit pricier solution.

*there is still some weather stripping in front of the battery and brake fluid covers to insulate NVH for the hood and since the flow is exiting at the rear of the engine bay it shouldn't have negative affects on aero.*

^i learned this stuff with my other car.the day i brought it home is was hot out.i immediately removed the engine cover(insulates heat which equals no good in the summer) ,rubber underneath the hood(air definitely gets there now) and the rear rubber,did tb bypasses and i have removed the splash shield that would normally cover the oil pan.i tried running without the middle section you described and removing it slowed down the heat escape from the bottom splash shield it seemed.

1 line over 220, and it is 100° f outside..... I have had my car coming up on the 260° f line when it was sub 50° s outside so you ain't even close. But at 100° f ambient outside it wouldn't take long to get to the 260° f line fast.

So you where about 240, Invest in a oil cooler, He wont get UPREV( Long story) so the fan mod is out, But both very well worth it, I saw nothing over 185 last week in the 100-103 heat. I have both oil cooler and the UPREV fan mod. :)

just relax......... it is happen when cars heatsoak

TIP; make sure the front of your radiator is clean and not full of bugs.last night i was taking the fang vents out and noticed my radiator was pretty much covered in bugs.so as soon as i was done with the fang vents,i took it to a car wash and sprayed the rad off with a pressure washer keeping adequate distance from the fins to avoid damage.

today is 87 here and after the car was fully warmed then sat for 15 minutes.i took it for a good hard spirited drive on the back roads going to redline a couple of times and then maintained shift points from 4-5k.surprisingly my oil temp did not go past 207 which before this it would get to 220 pretty quickly.so fang vents removed,clean radiator is working pretty good. :happydance:

Yesterday here it was 107 here in DFW....ughhh I drove the Z to work and midway through my commute it felt much more guttless (oil temp never rose above 200) when I punched it to get on the freeway, later that eve I drove the Max to Nordstrom. After a while it felt guttless to, Vq's just hate heat.


An old article from Oct 09 R/T Observed:

An observation we made over the week was the VQ's sensitivity to temperature. Engines prefer cool weather, but the VQ absolutely detests hot days.
