Jack, Many years ago I had the same idea on my BJ8 as to increase the air
flow through the left hand fresh air duct too. I noticed that the right hand
side heater blower housing could have the motor assembled on either side of
the housing. So I took a heater blower from a junked Healey at a wrecking
yard and reversed the assembly of the motor and housing so I could mount the
blower on the left hand inner fender in a mirror image of the right side. I
found that the blower cage turned in the wrong direction to eject the air out
of the outlet in an efficient manner, so I opened up the motor housing and
reversed the wiring to the field windings and was able to reverse the
direction of the motor rotation too. Then I had the problem of the hose on
the left side of the car being larger in diameter than the one on the heater
side. I made shims out of aluminum strips and built up the diameter of the
hose conections on the blower housing and firewall connection so I could used
the same original hose. I used a toggle switch on an accessory switch panel
to control it. I don't remember the size of the hose or the inner diameter of
the hose connection at the firewall. I do remember a mention of some one on
the list mounting a small fan in the inlet at the firewall to boost the air
flow and there were pictures, but can't find it in the archives. Maybe you
can give it a try or someone on the list will remember.

Subject: [Healeys] Air Intake Assembly Diameter
On the driver's side of my BT7 is a flexible tube that is supposed to being
ir into the cockpit by ram action.
Can anyone of those privileged to use their cars year round tell me what the
nside diameter of the air intake assembly (on page R43 of the parts
anual) that the tube is connected to?
There are a number of round 12V fans available from electronic surplus
ouses and if I can find the right one I want to try to improve the air
low when stopped.
Thanks,
Jack
