Setrab Oil Cooler Question

[Doug Eves]

Hello hohocc , didn't see a part # but tou can see the size and # of rows it has. Oil lines go directly to it from the rear of the motor so I can't see where any loads would introduced to it which is good. The thing is light and cools my engine oil so I feel it is better than the big heavy ones. Around 900 hrs and no problems to report.

Thanks Doug, appreciate your time getting a couple of shots of it. Good info to have when I'm into the firewall forward end.
Thanks.

Mine is the SET-110 which is a 10 row cooler, 3" wide. That one looks like a 13 row which would be the SET-113.

Matt, your earlier comments after a couple of flights suggested your cooler may be on the small side. Have you found any change after running the engine for a few hours? Have you operated in warmer weather yet? Does your engine have the piston oil squirters?
Thanks!

I was planning on using a Setrab Proline 115mm matrix 10 row for my RV-4 with an injected IO-320. Probably baffle mount. I have read through all the threads about Setrab/Mocal etc coolers and initially was alarmed about failures. However, as you can see from the link below, the burst pressure for the Proline coolers is 37 bar (about 550PSI!). Nobody seems to be concerned that what looks like a little cooler doesn't get the oil cool enough. I'm wondering about a 7 row cooler?

I had a 10 row on my IO-320. After installing EI, it could not keep the oil under 230 at altitude. I believe a 13 row may have been enough, but went to a more traditional cooler.

Wanted to post an update to this thread:
Since putting about 15 hours on the engine over the last few months my oil temps have gone down as the engine has broken in. However, spring is here and the ambient temps have come up so the oil temps I'm seeing are still about 190 - 210 in cruise. Again, this is using the 10 row Setrab cooler. CHTs are good. I'm going to check all my baffling, make sure it is all well sealed with no leaks and fly a few more hours. If things don't improve I may try a 13 row.
