the base kit produces 12psi on a stock focus with a stock exhaust
the boost drops as you remove restriction in the exhaust but you do not loose power. boost is just a number to measure the amount of restriction in a system.
with a full exhaust you will see about 10-11psi but about 5-10hp and lb/ft more.
with our cams we are seeing about 9psi but 250fwhp...
the BBK is designed to put you at about 15-17psi depending on mods.
the addition of a ported head will further drop the boost but increase the flow and power.
The BBK is a single pully on a PW snout.
there is a shop in the US working on a multi-pully BBK but i'd be worried about the stress on the three bolts used to hold the pully on.
the BBK is sold as a "tuner" kit and does not come with tuning. howver PW has used the stock PW tune with the BBK, it is not the best choice.
we suggest propper tuning with the use of a BBK.... just becarefull who you use for the tuning.
Crower2s would probably be a bad choice because of the large amount of overlap.
we have cams specifically design for the PW kit and are offering them at a discounted price with the purchase of a kit. $850 retail and $650 if purchased at the same time as a kit.
with a full exhaust, our cams, FR head and the base kit, you would probably more than happy for a long time. long enough to save for a built motor and BBK! :)
hope that answers your questions, if not, ask some more!
