With the addition of my 2270 I'm now pushing oil temps toward 230 on an 80 degree day. I am not surprised, but wanted to run it for a bit just to make sure an external oil cooler is truly necessary.
I think it is truly necessary. I've researched and planned this some, but I'm still looking for sanity check, comments, and answers where appropriate. You'll notice I'm trying to stick with Setrab for most of this under the assumption that the pieces should work together. 1. This will be rear-mount cooler: Setrab Series 1 19-row w/Fan. It looks compact, has the fan, and was recommended to me. It will be mounted somewhere under trunk / over gearbox, probably passenger side. 2. Sandwich plate adapter. I've considered going with CFR's system, but I'll probably stick with the sandwich plate route at this point. Which sandwich plate? I assume it needs to be low-profile to avoid interference with cross-bar, but these things run from $26 to over $200 depending, I guess, whether or not they have thermostat. I was thinking of going with this one: 3/4 x 16 1-inch Sandwich Plate 3. Oil line fittings. I guess I need 2 for the sandwich adapter plate and 2 for the cooler itself. From a planning standpoint should I assume straight, 45 or 90 degree angled, particularly for clearance purposes off the adapter? 4. Oil lines. Going with steel braided, and I was thinking about 10 feet of AN8. Any advantage/disadvantage to AN8 versus AN10?. I'm going to get the Koul Tool oil line tool to help fabricate these. 5. Thermostat fan switch - was planning on the Setrab 190 degree thermostat switch. 6. Then I guess I need to go fused or relay on the power. Need to research that a bit more. 7. Am I missing anything or any other gotchas before I start ordering stuff? As always, thanks for advice and help. Adding an external cooler obviously makes everything a bit more complex and crowded underneath. I guess I should have stuck with the original 1.7L I had years ago. NOT!

Greg, that's pretty clever running it through Microsquirt. I like that.
The only comment I can offer is that my thermo switch is on the outlet side of the oil cooler. In theory the fan won't come on if the cooler is doing its job without the fan. We'll see how that works. |

The only comment I can offer is that my thermo switch is on the outlet side of the oil cooler. Yup, so is mine. And yet I'm still seeing 215F (I was seeing 235-240 before shrouding and a fan.) If you decide you'd like to log oil temps and use the Microsquirt to control the fan, let me know. It's really not that difficult or expensive; I have $85 in the sensor and inline fitting, and if you're already using a relay then it's a simple wiring and config job. The advantage for me to do it this way was the ability to log (and real-time view) the temperature data, plus easy adjustment of the fan on/offrange if I chose to change it. Plus, I already have the Microsquirt! May as well use the damned thing. |
