I am having this nagging feeling that the intake tracts on my injected
(Lucas mechanical PI) Triumph 2.5 are too short.
It is a pretty conventional injection style arrangement, with a long
cylinder-shaped common plenum chamber with six equal tracts consisting of
a trumpet, a piece of rubber tube, a throttle body plus the inlet port of
course.

Surely, there must exist a formula for estimating a suitable length?
My own totally home spun theories about this would suggest 50 cm at 5000
RPM, but I guess that is probably way off.
