[Healeys] air ducting kit

[Richard Collins]

My vapor lock issue occurs for example at long stop lights in hot weather as expected to some extant, not while driving; but the other day when I stopped to refuel, the heatsink after turning off the engine caused the gauge to hit 200 which vapor locks me every time. So I push back, lift the lid and air the engine for 10-15 minutes and then it fires up. That usually attracts an audience which helps pass the time.   :-)
A pulley change on my car wouldn’t make a difference IMO.

 Somewhat relevant, I hope: Has anyone tried putting a smaller pulley on the water pump for more flow? Would that just make turbulence/cavitation in the pump and hose?

Hi Ira:

I am not familiar with the direction of air around the radiator in the BN4, however, the BJ8’s has deflectors built in to the frame in front of the radiator, but, not for the wind that drops down under the radiator.  So the introduction of the shovel from the frame to the radiator produces a hurricane velocity up and through the radiator on the BJ8. That alone should be sufficient to cool water.  But it does not move the water very fast through the engine back to the radiator, especially under low rpms.  So I have introduced an electric water pump (Aussie idea, as it does get hot down under) to keep the flow of water through the radiator to the engine through the water pump and back to the radiator.  it adds 150 liter per minute to the trickle produced by the mechanical pump.  I fact one of the listeners commented that he could turn off the fan and just keep the water pump operating on highway speeds. It was easy to install using existing hoses cut in half going from the bottom of the radiator up to the inlet on the engine, and 2 x 1/8th diameter holes in the thermostat to allow the water to flow during engine warm up.

After a run, I keep both the fan/EWP operating for a few min after the engine shut down which helps to reduce flashing of the hot water.  And, I have a large radiator overflow container to absorb boil over.

Why do you think most cars and trucks have electric fans, overflow containers, and some have an electric water pump.  21st century technology verses our 20th century.  They even have AC power steering etc. systems as standard equipment.

Best regards,

Bob Begani

I have not had my grille in my BN4 for a long time and it has become an identifying feature of my car. I have a grille, I just have had various reasons to not instal it. I like the Rally grill look and have been looking at the Cape International kits to accomplish the look. Plus anything that directs more air through the Rad cores is good .
So has anyone done this or another kit?
