I also was in the college mode in 1958 and bought my first new car a =
1958 MGA in April of that year so thought I must have seen the article =
after that rather than 2 years before it, because I did build a nice =
little box for the MGA. There was a left over part of it still around =
for a while, so I=E2=80=99ll look hard for what=E2=80=99s left so can =
give you the dimensions.=20
I can tell you this..It was a bought Radio Shack aluminum chassis box, =
with an aluminum backing plate made for closing up the air box. The =
backing plate screwed on to the box from the open or fender side away =
from the motor to close things up for pressure retention. The chassis =
itself was cut with the holes to allow it=E2=80=99s installation on to =
the carburettor air intake side instead of air cleaners, then the cover =
backing plate was installed with sheet metal screws and a small bit of =
sealant.
The carb fuel overflow pipes were routed into the airbox and sealed with =
tubing bulkhead fittings to equalize the air pressure on top of the =
float chamber to avoid the float being pushed up by the positive air =
pressure into the floatchamber bottom and shutting back fuel flow. =
Pretty sure I got this idea from someone else, so guessing I saw it in a =
mag too. My box looked a lot like the one found on the old LeMans =
A.Healey 100-4 motor from the factory.
I think the biggest gain came from routing cooler air to the carbs =
rather then some slight positive air pressure increase at 70 mph or =
above.
