For the ARC fins, which are, after all, only stuck on, the key is surely the heat conductive adhesive -- any old regular 3M trim adhesive tape would presumably not work very well.

hahaha, yah, i saw that it's by the real ARC. so how many of the 10x9cm or watnot sized fins did you mount on your oil pan?

I think 2-3. You can get some shears and snip the fins and the adhesive pads to fit tight spaces. I might try and add a few more segments of fin on my next oil change -- can't recall if I have any open space left. I'll try to get a pic next time too.

You can definitely fit at least two on the diff -- a cheap-o alternative to the Nismo finned cover. Not as flashy, but same principal

By an engineering standpoint as long as you have a good conductive paste between the oil pan and the fins this would actually work quite well. No different than an electrical heat sink.

I should also point out that before my trip in the mountians I had the plastic undershroud off the car and it would run down in the 180s that way. I might pull it back off to see if there is a correlation between running with it off and cooler temps. I would imagine there would be significantly more airflow around the engine with it removed.

I thought about adding a vent to the undershroud (and I believe there is a modshack DIY for that on here), but I don't remember what the final verdict was on what other effects occur -- poorer MPG by being a bit less slippery to air under the car or changing how air flows over the radiator, for example.

I think it remains an open question without further testing...

The only ill-effect I noticed was that the front bumper wasn't as rigid as it was before. Next time I change my oil ill leave it off again just to observe the oil temps.

It's a shame that our cars cant operate normally at the same oil temps as other modern performance or everyday cars. embarassing even. but there isn't much we can do aside from prolonging our enjoyment by investing in oil to air oil coolers.

I've had my belly shield off for a while before and to be honest, if there was a difference it wasn't noticeable. The front bumper is definitely not as rigidly held in place but i've gone for months with no shield and i spend a fair amount of time on motorways. Ever since i realised i could do any oil change just by popping the rear screws off the shield and folding it back, i havent removed the shield except when it had to come off.

Thanks for the heads up about the stick on heatsinks. You can buy Arctic Silver thermal compound adhesive from computer parts shops. It's an epoxy type glue. You can also buy the adhesive pads from some computer parts suppliers but i haven't seen any that would hold up to the elements. Speaking of which, computer heatsinks are really cheap.

How many Toyota Camrys or Honda Civics come with an oil temp gauge? These cars can and do overheat their oil when driving under severe conditions (city driving, spirited driving, etc). The only difference is they don't know they are doing it, ignorance is bliss.

Please don't start gluing computer heatsinks to the car.

why they put an oil cooler in an altima.... because racecar!

350z had the same one. Why not the 370z? Because Nissan cost cutting.

you can blame the government for raping japan for the unfair yen exchange rate at the time...

For anyone who wanted to see the ugly but functional use of the ARC coolfins...

I also have two stuck on my diff cover

njobe89 · 06-06-2014, 11:42 AM

highest mine has got in traffic was about 240-245 once.. usually it's about 180-200 mark. i always watch it thinking something is going to happen -_-

Jordo! Good demonstration of how the undertray does not need to be removed for an oil change! I only discovered this at my last oil change & it saves many minutes messing around with the million screws and the flappy cover.

I had the sudden severe throttle lag thing again tonight. It felt like the CVTC system was stuck in the high rpm mode so below 4000rpm there was a very flaccid response. Foot to the floor in 1st got me nowhere quick but once about 3-4k the motor came to life although not as healthily as it does normally. i had to restart the motor to remedy the problem.

Prior to changing to Nulon oil, it felt like the CVTC system was stuck in the low RPM mode so above 4k felt reeeeeally flat. Like as if a piece of wood was wedged under the pedal.

Anyway, my 25 row Setrab core has arrived and i will be putting together a custom oil cooler set up as the commercially made kits all won't fit my car due to my ram air scoops
