The P-1SC and the D-1SC both use the same housing. The internals of the D-1SC are designed to handle more boost than what the P-1SC can produce. If you have both of these blowers producing say, 8 psi, the D-1SC would end up having a larger pulley on the head unit, as it doesn't have to be spun as fast to produce the boost. In theory the P-1SC should start producing boost a little sooner than the D-1SC in the rpm band, but I really can't tell a difference between the two.
Many people start out with the P-1Sc as they feel that adding the supercharger is all they are ever going to do with their vehicle. Power is contagious, and once most of us get a feel for it, we end up wanting more. 8 psi is about all I recommend on the stock bottom end of an LS engine, adding forged rods and pistons to these engines gives you the ability to up the boost into the 14 to 16 psi range. The P-1SC isn't going to get you there, especially if you add more cubes, cam and heads.

Thanks,for the info,really want to just keep it rather simple on my wifes 2000 NHRA Trans Am daily driver.I'm putting Kooks LTH's, GMMG catback,and a Walbro 255 (if I can ever figure out how the pumps fuel line goes over the double nipple fitting,tight ain't the word ! ) I'm contemplating the Procharger route so she won't have the hassle of filling bottles.Will the 7-8 psi put these cars in the 11 second range?

Bob okay so I've been looking around and called a few friends with blowers and decided that im going with a ATI Procharger and only plan on running 8psi but in a couple of months going to forge my motor and run 15-17 psi should i upgrade to the F1-A? Also how much benefit would the new intercooler have?

Our internally stock LT1 Formula has an ATI ProCharger P-1SC, and it runs 11.32 at 118 mph. The stock LT1 engines don't produce near the horsepower that a stock LS1 engine does, and this also applies when it has forced induction added to it. We will be removing the a.c., going to a manual steering rack, lightweight brakes, and some other mods in an effort to eliminate weight in this car to get it into the 10's. We have all the parts, just not enough time!

I've just installed the Walbro 255 direct fit, if I install a Procharger and limit the boost to 7.5 what size injectors will I need and whose do you recommend ?Will the stock inline fuel filter suffice ?

EPP is located in Columbia City, IN.
The D1SC, and the F1-A are very different Superchargers. The F1 is pretty much a full race supercharger. If you run very low boost on the F1 I suppose you'll get the same HP numbers as with a D1, however the F1 is capable of much more boost/power.
The price in the units aren't that much different, and Bob will get you the best price on either. It's more the money required to be invested in good internals that costs so much. If you are planning on skimping on spending a bit of money (trust me on this one, you are looking at a good $10,000+ just in the motor to do it right) for the motor, then I would stay with the D1, and run LOW boost if you want to last. An intercooler will help, but even so, 6-9#'s can do some damage to a stock bottom end LT1 or LS1 motor even if it is setup properly. Most guys running 6-9#'s usually only last about 25,000 miles at best with well tuned stock bottom ends.
If you are planning on running a fully forged setup with a low CR, then I would just say go with the F1, and run whatever boost fits your HP desire.

Siemens 60lb fuel injectors are what I recommend.
A clean stock fuel filter works just fine. Bob

With a F-series blower vs a d1sc you will notice more midrange power on the F-series.

Rods, pistons, and ARP head studs are all you need. The stock crank is good for 900 to 1000 hp.

These two cars are several examples of cars we have built by replacing the rods and pistons.
