It's out of spec. .

I've run a single 044 pump with system pressure at 80 PSI (5.44 bar) and dyno'd considerably in excess of 300 RWHP - I don't think that's your starting problem, although this may indicate adjustment required or an issue. It should start even with a dead pump in a dual pump setup.

I then tested the Cold pressure and got 2.3 bar compared to the 1.8-2.2 bar it's suppose to be according to the previous thread(1978 no start).

So what do you guys think about these numbers?
Slightly high (lean). Shouldn't make it die once its running.
'77 S with '78 930 power and a few other things.
