[T3] Old Type IIIs

[Dave Hall]

Most of the side-draft carbed Type 3s were 1500cc, though later ones sold
into poorer markets were on 1600 engines.

Factory quoted fuel consumption was about the same as the high compression
twin carb 1500S and 10% better than quoted for later 1600 twin carb, but I
don't know how comparable those figures would really be - there was a lot of
movement of standards for quoting fuel consumption around that time.
Typically it was at 1/2 load at 3/4 of top speed, which penalised a faster
car anyway, but later urban cycles and mixed highways were included.  

Independent motor industry testing over many 1000s of miles in 1961 on a
Notch got 30.1mpg Imp (about 24mpg US) compared with 29.5mpg Imp (about
23.6mpg US) on a '69 FI Fastback, so there really is little difference.
That's pretty typical, and corrected for mileometer inaccuracies.   What an
individual gets depends so much on local conditions, driving techniques etc,
and even individual differences in the vehicle, it's hard to be confident of
exceptional figures, though the longer the test runs, the less the variables
affect it.  Even my modern diesel VWs vary by almost 10% from summer to
winter, but I couldn't say that shorter journeys and colder weather wouldn't
explain most of that.

What is the performance like on the original side draft carb? I have never
even known anybody (personally) still running that setup, but have always
been curious.
