+1000 hrs flight on this with no problems. Mine are mounted low and toward the outside of the firewall, inside a custom heat shield with a cooling tube. Klaus has no problem with hot side installs if done right. Out of real estate so Lightspeed is staying put. If I have to go remote, I will try to fit a 13 row but not the Show Planes route. Lycoming states 245 max continuous and normal continuous of 185-210……my existing 7 row is getting the job done but I would like to stay at 200 or less at all but the most extreme conditions.ġ3 row wont fit on baffle, and if it did would probably overwhelm my reinforcing structure and lead to more cracks. Got up to 220 when flying at 90 kts on very long approach on a very hot day into Osh last summer. Climbing on a hot engine, fast/extended climbs, slow flight on hot days are the only problem. I have squirters which is why I have max CHTs of only 300 at economy cruise. No matter what, if I replace my 7 row with an 8, 9 or 10 row, all of which have more area, all of which may fit on the baffle, and I remove my shutter, I should get some improvement and some is all I need.
#Airflow performance oil cooler series
What makes you think the SW are more efficient than the Aero Classic HE (High Efficiency) series? Do you have some data? I will probably go with an Airflow Performance X series if I can as their data shows superior performance. Normal cracks early on but reinforced and no problems since. Put some thermocouples on them for temperature reading.Īctually have over 1500 hrs on my baffle mounted cooler. You might be surprised how hot those LS electronics are getting. Your EI boxes see that heat and get hot, especially after shutdown and heat soak. The engine and exhaust pipes are radiating and convective HEAT. I would not disregard the remove oil cooler idea.Īs far as light-speed EI boxes can you move them to the cool side of the firewall? Even without out oil cooler, the area under the cow is hot hot hot. Get one or mock it up and see if it will fit. I have no idea if you can mount a monster 13 row cooler on your baffle. What are your CHT's when your oil is 220? The engine you have I think has piston oil squinters. Tell them what you have.Īlso you can increase your cowl exit air. I could have my story wrong but there is some truth to it. If you are going from an original SW to Classic you may find it not cooling as well. "Classic" makes a fine cooler but they don't have as much cooling area as original SW coolers. Keep in mind original Stewart Warner oil coolers (no longer made by SW) are more efficient than new ones. Do try and keep temps as low as possible with shallow climb, step climb. Suggest Aeroshell 100/80 (or W100/W80) and change every 50 hours or 3-4 months (regardless of hours) which ever comes first. So always not a fan of this mounting, my bias.Ģ20F is hot but at the limit.
With oil cooler weight (cooler, hoses, oil in cooler and hoses) weight on the baffle in my experience will result in cracks at some point.
#Airflow performance oil cooler free
Hate to nay say about baffle mounted oil coolers, because you have 800 hours trouble free structurally.
