Oil cooler tech
Is that measured on the pre or post cooler part of the sandwich?
|
It would have to be pre, because the post cooler route goes through the filter and then into the block through the central pipe.
250 pre-cooler is nothing to worry about. |

Depending on the design of the plate, and its orientation, it's possible to take a measurement either pre or post-cooler. This one, for instance, has ports on both sides: https://www.miataturbo.net/attachmen...ine=1441934897 |

Yep, that's like mine and why I asked.

Mine is just a sandwich plate. Just for gauges/spacing.<br />
<br /><br />What temp should I be worried? <br />Rotella T6 |

I'd start thinking of pulling off or doing cool down laps at like 240... running a boosted Miata with no oil cooler is kind of asking for trouble.
<br /><br /> <br />I have a 25 row setrab. <br />I was refering to where the temp was taken. |
Oh. I'm assuming that temp is before the oil cooler so then that means I have no clue for your scenario.

Oil temp question.<br />
<br /><br />At the track today, I'm seeing 250 indicated in my sandwich plate. I know 250 is getting hot when its in the pan but my sensor is in the plate. What temp should I start doing cool down laps? Given the fact that many of them shut it down around 270, I would think beating on it all the time near say 250 is probably a bad idea. If you did it, I'd swap the oil afterwards. |
Isn't oil at the filter 10-20* hotter than the oan?
|
The question remains, is this oil temp prior to the oil cooler? If yes, and the oil is then being dropped to 220-230 in the cooler then it is in the acceptable operating range for T6 synthetic on the track. I would back off at about 260-265F. Racers often run higher in the heat of battle if they must, but they rebuild engines more often.
It typically gets slightly more difficult to get hotter as the temp increases (unless you have real shortcomings in the cooling system) because as the difference between ambient and the oil temp continues to grow the cooler actually cools a little better, all things considered. Don't cook your engine. |
Is pre cooler.
<br />I will be changing the oil and sending a bit to Blackstone. |

I read online that the "normal" spot to measure oil temps is in the oil pan sump, so that's where I put my sensor. I wonder where the germans put theirs? I'll look for it on my mercedes next time I change the oil. |
I would think the hottest oil would be coming from the bottom sides of the pistons and the oil control rings since that's where the fire is.

<p>Wouldn't the best place for a temp sensor to be post cooler, so you know the actual temp of the oil going into your bearings?</p><p>Then you can look at the properties of your oil and see when you should shut down.</p><p>I also have the issue of not trusting my oil temp gauge, because my coolant gauge wasn't exact out of the box.</p><p>Oh well. Good thing its a 1.6</p>

iMO you are correct, but then you take that hot oil and compress it, compressing anything makes it hotter.

<p>But why do I care how hot the oil that just cooled my bearings is? Don't I want to know how hot the oil that is about to cool my bearings is?</p>

Oil will get a bit warmer when pumped due to friction, but that's pretty low (low friction is, after all, the main point to having oil). I suspect it doesn't really matter all that much where you measure it. Personally I change the oil before every track day, because the cost just isn't significant compared to everything else. --Ian |
