We have done several that way years ago. Now we use the B6 oil filter stud which is short enough to not require a spacer.

 

I prefer to leave it in for any car driven on the street - it does a good job of bringing the oil up to temp more quickly, and with the cooler in place, the oil rarely runs more than 20*F higher than the coolant temp, so it's not putting much heat back into the cooling system at operating temp.

For track cars, you can delete with the B6 filter stud.

 

I used a glowshift sandwich plate + setrab plate on my car. I removed the stud and simply cut it at the right lenght. Simple!





Just with the sandwich plate.

 

This needs to happen

 

Wait wasnt there an issue with the fittings on the mocal plate clearing the block if you used the 1.6 nipple?

 

IIRC there's one orientation it fits in, but it was pretty inconvenient for the way I wanted to route my cooler lines.

No ****. I've been sitting here waiting for someone to tell me where to send a check.

 

I'll just leave this right here:

In the event you are looking for the shorter B6 oil filter stud, Mazda's PN is B630-10-319. They call it a "Joint".

 

I'd like to put out a call for data. Ideally, someone will be able to measure oil temps pre and post cooler. But, this requires two gauges. Failing that, any data on post-cooler oil temps (before re-entering the engine) would be good. The goal here is to get a feel for exactly what kind of delta-t we are seeing through an oil cooler in our cars.

Please include
a) usage conditions (track, autocross, texas mile, etc)
b) ambient temps
c) oil temp(s). If only post-cooler oil is being measured, please include an estimate of oil temps pre-cooler for that car under similar conditions, if known.
d) oil cooler in question, and how it is ducted (or plumbed, if oil<->water)

 

When I get all my datalogging setup I'll do it. Wanna buy me an extra sensor and adapter

 

No bitch I gave you springs!

 

Very true, I'll try and figure out how to get a post cooler temp. I bet if I teed off the pressure sensor I could do it.

Would this work:

Pre cooler temp in sandwich plate underneath mocal plate.
Post cooler temp in pressure sender port?

 

By pressure sender port you are referring to the stock one? I don't have the miata oil flow path memorized, let me look around.

Edit:

Hmm, I don't know. According to this diagram, it looks to me like by the time the oil gets from the filter to the oil pressure port, it may have equalized to whatever the block temperature is at that point. Iron transfers heat good.

 

Yes stock one. I believe that is filtered oil, and my cheapo sandwich plate is pre filter.

 

(Sandwich Plate Temp - Oil Pressure Port Temp) is the delta T we're after.

You could also do (Oil Pan Temp - Oil Pressure Port Temp), but I would expect that to be a lower number.

 

Yeah, I can do that one. Don't have a pan temp sensor. Need to get the right T adapter. I think andrew just released one.

 

Do you need to borrow a Sharpie?

 

I will do something like this on the oil system on a track day this summer and post it

 

Just realized that my temp sensor won't fit in an adapter because of how long the tip is. Need to figure out another way to do it.
