I am running dual DCOE's on my Alpine (well, at least I was, and will be
again). My car is a left hand drive. Dave won't need to worry about the
master cylinder interfering since he has a right hand drive car. For
everyone else, I solved it by buying a shorter MC from Pegasus Racing
supply. It's the same diameter inside as the early Alpines. So, like
them, I'm not running the servo.
As to linkeage, I am running a cable linkeage. It was extremely easy to
set up and I am very happy with how it works - with none of that slop that
the mechanical ones have, or develop. Let me know if you are interested in
a description of what I did.
As to the brace, with my manifold, there is interference. I simply took
mine off. I have meant to, and still mean to, have one built to put back
on. But, I haven't done it yet. The whole reason they were put there was
because the PROTOTYPE Alpines suffered a front end shaking that they hoped
to eliminate. I can honestly say that I have noticed NO front end shake
without it - and I have driven many types of hard, rough, bouncy and smooth
roads. In fact, my car runs firmer and smoother than it ever did before
(but I did redo the entire front end).
There are four different brace set ups that I've seen. The factory race
car Alpines for Le Mans (the ones with the Kamm tail rear end) simply had a
bent bar that went around the carbs - using the stock mounting points.
I've seen someone who cut out the stock mounting point on the firewall and
moved it over to the right. I've also seen someone who built a plate that
mounted to the stock mounting point and then spread to the right against
the firewall to which the brace was welded. Then I've seen someone who
left the brace as is, but trimmed the ram horn down to clear. When I get
to it, I'm doing the factory Le Mans style. I know that basically
eliminates the strength of the straight rod. But, as I said, I have not
noticed any of the symptoms that gave rise to them adding it in the first
place.
Aside from the lack of shaking, I should point out that some racing
organizations might have rules that would put you into a different class
because of the modification (not to mention the Webers).
I have the VW Derrington type intake manifold. The molds for this manifold
were sold to TWM ("The Weber Man") in Goleta, California. My manifold was
one of the last ones he made before he lost the manifold mold. A number of
folks got together and he made up a new mold. I think he will still make
them in batches of 6 or more.
I don't know about the new mold, but the stock H120 manifold narrowed the
intake from wide at the carb to small at the head. This was done to
improve throttle response at the lower end. I opened mine up and am very
happy with the throttle response.
