RV-10 Airflow 2007X Oil Cooler

Has anyone installed the airflow oil cooler and can provide a comparison with vans supplied oil cooler? I recently flew out of a high altitude airport and had to reduce my VS to to 100/min in order to remain around 220 on my oil temp.

It is possible that my recently Vernatherm replacement has gone bad. I am in the process of checking all the boxes including the possibility of viscosity valve installation..

If you do not have a comparison, can you comment on the oil cooler performance?

Thank you.
 
Not enough information to vote on replacing the oil cooler, Venatherm or both.

I assume you are using the Van’s Fire Wall Forward kit Niagara 13 row cooler. I note that Van’s now uses the AirFlow Systems 13 row 2006X cooler for the RV-14. I don’t know for fact but I assume this shift was to address high oil temp issues with the IO-390 engines. I ran the AirFlow cooler on my first RV-10 and have a new one sitting on the shelf for the new RV-10 build. I never had an oil temperature problem with this cooler.

This is what I said in a related thread about the AS 2007X cooler in my 10.

WTB - TCW Tech servos and oil cooler butterfly valve

About to need/buy a couple of servos for my RV10 heater valves and oil cooler and I thought I’d check here to see if anyone has one laying around they’re not going to use. Also need the TCW tech oil cooler butterfly valve. What do you have laying around??? Zach

I don’t have a direct real world comparison in the same airframe but here is a chart that I modified to add various data points to in order to compare. You may find it helpful.

The 1649 and 1718 are Stewart Warners - oil flow rate in brackets.

I don't recall if it is a 13 row. I had the original and then I installed what was supposed to a more "efficient' cooler and saw zero improvement. Thanks for the comments.
