Regarding this subject the term =E2=80=98shovel=E2=80=9D is generally used =
to describe a =E2=80=9Ccoal shovel=E2=80=9D shaped scoop to intercept the a=
ir stream forcing air into something. =20
The two pieces on a 100, especially the flat bottom panel, are there to dir=
ect air coming through the grille to the radiator core and minimize the air=
from redirecting under the radiator/chassis. The later cars use the two s=
ide splash panels that attempts to control the air flow to the radiator wit=
h out the lower flat panel used on the 100.=20
The shovel scoop as shown in Simons photo actually scoops the air from bene=
ath the front of the car and forces it up towards the rad core. At speed th=
is would potentially increase the air flow through the core. Sounds good b=
ut in most cases the air flow and the cooling ability of the stock setup on=
our cars is adequate at speed.=20
This once again gets back to the fact that most of our cooling problems are=
while idling when the stock fans produce very little cubic feet of air flo=
w. Increase the stock fans to 2000 RPM and the fan is now producing more CF=
M than most of the smaller (12 Inch diameter or so) electric fans on the ma=
rket. I ran the numbers a year or two ago and do not remember the exact num=
bers as that sheet of paper has been lost in my sea of Healey info. I may =
have posted that info to the list back then but that source also did not pr=
oduce any results.=20
Hope everyone is having a fun day=E2=80=A6.we are about to get, in the next=
few days, the first dusting of snow for the season. That is if you trust t=
he weather folks.
