I recently bought a '69 Porsche 911T targa. This car has a 2.0 litre
six with a compression ratio of 8.6:1, and 110 hp (S versions have 160
hp and 10:1 compression). Now, this is a little more than an MGB, and a
little larger engine (but lower compression). The interesting thing is
that even the 110 hp car has 2 triple (40 mm) throat webers - i.e. 6
carbs. When I compare to the MG's 2 carbs of 1 1/2" (about 40mm) I have
to think the Porsche is at least a little overcarburated. I wonder how
much more effective three SU's with a special intake manifold would be
than the webers - of course I know it would take a lot of needle
selection etc, but the idea is interesting. I don't really plan to do
it, just dreaming.
Any thoughts??
