Jab-thusiasts,
=C2-
I have one of the original "old style" oil cooler s on my 3300 and a JabUSA
3300 FWF kit installed on my Zenith CH601XLB. =C2-Many of you have been ki
nd in giving me advice about my CHT's, I added "Eybrow" sccops to my cowl an
d magically I =C2-have improved my CHT temps to just under 300 F on these
85F days. =C2-My goal is to attempt to lower things a bit more if possible
.
=C2-
My next battle that seems to be looming is now Oil Temps. =C2-I seem to be
running at 220 to 235F =C2-in cruise. =C2-Yes, I'm very aware of too hi
gh =C2-oil level and high oil temps. =C2-Curiously before I did my B mod
s I used to run from 190F to 215F and I am curious to why I'm running hotter
than usual. =C2-Any suggestions on getting temps down?
=C2-
In looking at my old style oil cooler and the large NACA vent that supplies
it with air, nothing is different from when I installed it, except I added a
scoop under the cooler that meets with the bottom lip of the NACA vent.
=C2-If I run without the vent scoop my oil temps head for 245F+, =C2-the
only other thing that is different is that I covered the 2 holes on the old
style RAM air ducts that are supposed to spill air over the top of the engi
ne block.
=C2-
Anyways, that's where I am at with 288 hours on my airframe and powerplant I
would love to just go flying with out having to worry about temps, I think
the Australian Manufacturers could do a tad bit better in getting thing dial
ed in and functioning as "advertised." Also, =C2-It should be interesting
once I get my Europa in the air with the "newer" style 3300 engine and new
=C2-style oil cooler and see what I get, probably an apples to oranges com
parison.
=C2-

Jeff,
I would be looking at increasing the exit opening or making the lip a bit
more prominent. Maybe you are damming up the incoming air because it can't
all get through the radiator and baffles
