1 cooler, no, AEL22770 - B&C or equivalent, ASA No Hassle preheater, no.Installing a YIO-O360-A1B6 on a 7A. Couple oil questions:
One or two oil coolers? Why and how installed?
Oil cooler shutter?
90° oil filter adapter? What model?
Oil pre-heater? If yes, model?
Dehumidifier?
Thanks guys!
why 2 coolers?
Angle valve engines tend to need more oil cooler, but generous finning makes CHT control easier. Parallel valve engines typically don't have piston squirters, so oil temperature runs cooler, but less finning makes CHT more challenging.
Your A1B6 is an angle valve? You definitely don't need two coolers, just a single large one mounted on the firewall, or on the engine mount.
I'm easily cooling a 390 angle valve with an SW/Meggit 10611, roughly the same size and performance as an Airflow 2006X.
Thanks Dan,
That makes sense, especially since Vans sends a small cooler with their firewall forward kit.
I have an advantage in that a friend in the hangar is building a 14 and it looks to be a very similar setup so visualizing things is fairly easy. His mount has the oil cooler attachment points built in. My original engine had the cooler attached to the back of the engine. Thoughts on how I make that transition?
My previous engine also had a shutter which was useful in bringing up temps in winter. Is it your opinion that is unnecessary?
Which is typically fine with a parallel valve, the engine for which the airplane was designed.
See below. Mine is mounted on a plate which hangs on the motor mount, and is ducted to an exit bell. Quite a few builders mount to the firewall with a plenum box. You can buy the RV-10 plenum or build something, depending on what size cooler you want to use.
For an angle valve, generally not necessary. However, I live in the South, and often forget about the arctic regions found north of the Mason Dixon
.
There *IS* a performance difference between oil cooler mfg.
