Subject: [Healeys] Curved or Straight
Hello
Once again I am about to investigate the engine cooling of the Healey Dunca=
n. Nothing highly unusual with it in that it=E2=80=99s a Riley 2.4 litre en=
gine and unpressurised.
Part of the process is to replace the existing Kenlowe electric fan with a =
more modern unit. The Kenlow sits over an inch from the radiator surface wh=
ile a modern unit should only be a few millimetres. Of course it was never =
fitted with an electric fan when new, but it=E2=80=99s simply not coping wi=
th the warmer Australian climate.
I will be doing all sorts of wonderful things like removing the cylinder he=
ad to replace the cooling tube between number two and three combustion cham=
ber, refurbishing the radiator, rodding the block etc etc.
The question that=E2=80=99s on my mind concerns whether to install an elect=
ric fan with curved or straight blades. Australian manufacturer Davies Crai=
g says that straight blades are best, but they would say that as that=E2=80=
=99s what they make.
Anyone undertaken any research as to what=E2=80=99s the most efficient?
