Dennis was/is somewhat correct. The fuel flow, as measured on a flow bench, was
greater in the Strombergs (pre-emissions) than the SU HS-6's. This was
researched and checked out when a certain vintage race TR4 switched from
Strombergs to SU's and had less straight line top speed, and was running higher
than desired exhaust gas temperatures at wide open throttle. No amount of
richening would cure this in the SU's. Finally, the racer (Uncle Jack) drilled
out the jets in the SU's to a slight oversize, and the problem was solved. BTW,
when running Strombergs, many racers resorted to SU needles and made shims to
hold them in place, as there were so many more tuning options with the SU
needles than were available for the Strombergs.
