REFLECTOR: One or Two oil coolers?

[steve korney]

""cruise altitude (8000 ft.)  I cruise at 155-160 kts, 2600 rpms, 8 GPH, 
LOP.  One cooler will do the job if installed correctly.""

Your not making a lot of horse power at that Ronnie... At 200 horse power I 
don't think it would work.... Some of us like to run full power and one 
cooler just won't cut it...


Best... Steve

I agree with Scott - one oil cooler is enough.

I got one cooler mounted up front.  Works great with my IO 360 200 HP.  Has 
for 330 hours.  As I have mentioned before, it can run hot if take off right 
after shutting down like picking up Young Eagles.

Also works great on those long taxi runs at Oshkosh and Sun-n-Fun.  320-330 
degrees is the norm on the ground and in cruise - I have my high oil temp 
alarm set at 360.  If it goes off, I lower the nose a bit, pull back on the 
power a bit, and we keep on climbing to cruise altitude (8000 ft.)  I cruise 
at 155-160 kts, 2600 rpms, 8 GPH, LOP.  One cooler will do the job if 
installed correctly.

There's only one cooler on most other airplanes - I don't know why the 
Velocity got stuck with two???

       I also have an engine compartment cooler in series with the nose 
cooler.

   Wow, You are in complete disagreement with me, apparently on both my 
suggestions regarding oil coolers,as you say one is good enough, yet you 
apparently have two. Hmmmm.
