One point missed there Daniel...
on a single DCOE 45 (yes two barrels - two carbs in one)
very few people will run anything larger than a 38mm choke (1.49")
You'll simply never get the venturi velocity up into a usual speed range.
The HS6 is a 1.75" (44.45mm) but the velocity is held higher
do to the variability of the venturi size (constant depression)

John,
I have just been to your web page and your car does like pretty neat. I am
interested in your carb choice because only the other day I was wondering why
on earth no-one runs a pair of 1.75" SUs. In David Vizard's early Mini book
he lists this as a combination that can be used. Also while there may be
those that consider a pair of 1.75" SUs over the top, in fact size for size
there isn't a whole lot of difference between them and a 45DCOE (in fact 1mm
per throttle plate) so they certainly should work.
However, your comments below have thrown me a little. You say you are
running a pair of HIF44 carbs but the photo on your web page shows a pair of
HS (6s) carbs and in the text you say you are using HS6s - did you upgrade
the car since the photo/text was produced?

Depending on the cam, etc., it could be a good single unit. I'm running two
of these on my 1380 with 286 cam, head, 1.5 rollers, etc. It's the best
dual
setup I've ever run, but it is still dual.
