How many seconds on a cold engine, with 20/50 oil in, should the average time be on a good 948 engine, (using an earlier split screen gauge) to begin to register pressure after the engine starts. Id be grateful to get a response.

i'd say on mine its around 2/3 seconds. it then sits at around 55psi when cold and drops to around 30psi when fully warmed up.
