Is the location of the injector in the throttle body (ie relative to the inlet port/valve) significant? Every factory individual throttle body that i've seen has the injector on the top of the TB, pointing toward the back of the inlet valve. I'm looking at adding FI (Speedy of course) to a Suzuki GS1100 (air cooled 4 cylinder from the early 80s), replacing the four carbs with a TB from a late 90's Suzuki GSXR750. Ignoring for a minute the considerable amount of work just to make it fit, when this manifold is installed on the GSXR, the injectors are on the underside, pointing more or less to the top of the port. As I have to make adapters to go between the head and the TB I can mount it either way up. I am sure Suzuki knew what they were doing when they built the GSXR engine, but, can anyone suggest if there is an advantage over the more conventional orientation?
