I didn't really mean the extreme rear edge, just in back of his air box
somewhere. Depending on where that is, your point is valid -- it may or may
not work. The center of the bonnet is usually a low pressure zone, due to
the Bernoulli effect (explaining the tendency of B bonnets to pop open
suddenly at speed).

That's certainly true, although in this case he already has at least one
<g>. I had another idea... he says he was using a 14" base plate. That's a
pretty big air cleaner. MY 4.5L V8 (not in an MG) uses an 11" air cleaner.
If he just reduced the diameter of his air box arrangement, it would allow
more ambient air flow around the carb area.
I kind of doubt he can squeeze any more cold air ducting in there than he
already has -- the problem seems to be restricted space.
