Sergio Dimarmo asks:
"What's the big tadoo about these manifolds and carbs? Is this a better
setup than the standard Stromberg carbs? What are the
advantages/dis-advantages of switching?"
If you have to ask (1) we can't tell you and (2) we'd have to kill you if
we did.
Quite simply, Webers are known by some as the *ultimate* in
carburation for high performance, as most racing cars of the 60's were
powered by Webers, especially anything Italian, and including the Alpines
that raced at Le Mans (and won the Index of Efficiency mind you). That
being said, there are some who would rather have the more modern and
efficient injection (case in point, Jarrid), there are some who prefer
Delloratos, and there are some who prefer stock. There are three
disadvantages (1) cost, (2) not legal in most states, especially if there
are smog requirements, and (3) getting the right jetting can be difficult,
especially since it depends upon altitude, moisture, barometer, time of
day, pull of the moon, etc, and if the carbs are too big for your engine,
you are worse off, for each Weber (of "dual Webers") is really two
separate carbs physically attached to each other giving you one carb per
each cylinder.
I am running dual Webers, with a special high flow head and matched cam
(each by Holbay). The car runs great, gobs of power, and the RPMs just
keep going up and up with more and more power. It is still giving plenty
of power at 6000 rpm and wants to keep going, but I have not spun it
faster. The only one drawback I have encountered is that with the
higher power at the high end, it loses some at the very low end and needs
more rpm to pull from a stop. But who is stopping!. (You will need
Jarrid's injection to get the power at both ends).
So there you have it. Prepare to die (or at least empty your bank
account).
