OK Jack,
Since you now seem be the target of choice for carburetor/manifold queries,
permit me to pose one more.
As you know my racing M.O. has always been subject to a certain amount of,
well let's say, unconventional motivation. Art-form, discomfort, and
self-induced complexity seem to have all crept into my program. With respect
to carburetion, 6 years ago I bought a pair of 2" SUs. They were clean and
shiny and cost only $100. More importantly, I liked the authoritative scale
of them on the engine rather than those ugly little Strombergs (which always
started easier and ran flawlessly).
My cam and compression ratio are relatively mild and the motor makes only
125 hp @ 5500 rpms (and that's my shift point).
So here's my question: what would you speculate I give up in hp and torque
because of my compromise in carburetion?
My argument for using the larger bore is that the piston will only rise to
whatever level it requires to suck in the air it needs. That is to say if
the cfm is satisfied with the piston open 80% of the way then everything is
copasetic. You buy that?
Now don't laugh at my ignorance. I wouldn't laugh at you if you didn't know
what the magnetic compass does at 7000 ft directly above the magnetic North
Pole, inverted and at positive G's, would I?
