I think the most I have seen was 15psi on a 347.I dont recall the pully size but if you want to go tha high I would go with a D1sc.because it seems to me it would be less taxing on the s/c.
That is very true. A D1 is just getting to be in the sweet spot at 15 psi where as a P1 is running out of breath at the same point.

How much boost the blower can produce depends on many variables, so it is hard to predict how much boost you are going to see.
* Cubic inch. The larger the engine the less boost it will make with a P-1SC.
* Headers and exhaust. A better flowing system will produce less boost, requires a smaller pulley to regain the loss in boost. Ultimately though, more power will be gained.
* Camshaft and heads. A camshaft with some overlap will leak out some boost through the valves. Better flowing heads react a lot like a better flowing exhaust system.
* Altitude. Elevation plays a big part in how much boost is produced. Those people living in the higher elevations have to spin the blower harder to see boost.
* Condition of engine. An engine with real good sealing rings will ultimately produce more boost than one with worn rings.
* Rpm. An engine that is spun up higher in the rpm range will normally produce more boost.
