running 2.0 to 2.5 should be fine. That's what I have used to feed two HS-4s
on a high reving 1296 Spitfire.

Another elementary question:  What fuel pressure is the list using for the
original stock SU Carburetors for the TR-3/4 engine.  I know that this has
been
discussed before.

We recently mounted a fuel pressure gage under the hood between the
regulator
and carburetors.  Someone who I had worked with at Duquesne Light in the
70's
set my regulator, and I have been racing with this setting ever since.  I
plowed through both the red and the gray books and did not find any
recommended
fuel pressures.  Then an old article surfaced recommending 1.5 lbs. pressure
to
SU carburetors.

I am presently getting 2.2 lbs pressure to the carburetors.  Maybe a little
more pressure is required for racing.
