How to you run the lines from the sandwich adaptor? Do they go under
the motor - kind'a exposed, or did you route them some other way?
------------------------------------
Metal lines being exposed isn't a problem. I plan to use about 1 foot of
rubber coming off the adapter plate, to copper / or steel lines forward
to the cooler area and another 1 foot of rubber to go to the cooler
connections. The cooler will go up beside the frame in the inside next to
the heater 4" duct. (had it there before). This area does not get splash
from the wheels in wet weather and judging from the dirt in the area,
remains pretty much dirt free.
I'd like to avoid fans and such. The cooler is in a decent air flow area
that can have improved air flow with just a metal flap to direct the air
flow over the cooler.
I've never experienced overheating except at highway speeds where the air
flow would be very good.
This cooler is the size of your computer keyboard and that's a lot of
surface area when you consider seven passes approximately 2" x 23". That
is about three times the size of the stock type IV cooler that I intend
to leave until the new cooler has proven itself. The larger cooler and
lines will add about a quart to the oil capacity which in itself would be
a help.
Its real nice to get the installation done right the first time with no
oil leaks.
I was hoping to find someone that had specifically used this RX7 cooler
with the thermostat feature. Since the RX7 is a rotary engine it has a
requirement for large oil flow to accommodate the high RPMs it turns.
This is just a test project for me and I'm not going to be married to
anything I do here. The Westy underside looks like a vast open wasteland
until you try to find a good place for the oil cooler.
I like your idea of placing the cooler above the tranny but airflow is a
problem at that location but like I said with this big cooler the ambient
air temperature may be sufficient to cool as much as is required.
