Thanks. Since my cruise vacuum is 15" and I want to use small main jets, I'll need the PV to kick in sooner than usual as I get on the throttle.
The car is already accelerating briskly from 3000 rpm at 10" (and at 40% throttle where the secondaries start to open, there is still 6").

9.5 might be a little high (I run an 8.5 in the old 800 carb). But unless I can get a sufficiently lean highway cruise by dialing in the main air bleeds, (which will require reducing the main jets too), I don't think the 5.5 PV that's in there now will open soon enough.

Anyhow I have to get the overrich 3000 rpm cruise sorted before I worry about more enrichment for WOT
