I would go with the DS1C, you can make the 550 or so on the stock bottom with less boost and when you go forged you can up the boost to make more. I went with the DS1C to start with, but then I went with a forged bottom and nothing but fun

If your going to forge the bottom and are ultimately looking for some extreme performance the F1 series is the way to go. If your SURE you won't want more than 550rwhp...then save the $$$ and get the P1....one thing to remember...many FI projects started out with "I'll be happy with 550rwhp." and like myself pushed it to 850.

So I started with 750 rwhp, I guess the next step is to get with Arun and join the 1000+ rwhp for my next increase

I just recently finished the install on mine and the shop had the 4.xx pulley on it and it was producing too much boost (12+psi)not good for stock bottom end... then they ordered the 5 inch (I believe) and it brought the boost down to a managable psi 7-10 yes for some reason it climbs as the rpms raise but it doesnt hit 10 until way high in the rpms...so for a stock bottom end with a D1 you would need a 5 inch or slightly bigger to obtain what your looking for I ended up with 560/500

Your choices in the Procharger line are the P1sc, the D1sc and their F series blowers. The folks who are steering you toward the D1sc are giving you good advice. It's worth having the larger 8 rib pulley (less belt slip issues) and greater ability to expand if your desires change in the future.
My story is fairly typical. I started with the D1sc and 8 lbs of boost. I'm now running a forged bottom, meth and 15 lbs. of boost. HP is addictive.
PS. As for the F series blowers, those are great if you plan to run 13+ lbs of boost. They have a higher step up ratio and can run larger sc pulleys. Sounds like your not there (yet). Of those, I'm told the F1a or c would be the logical choices. The F1r is typically for 16+ lbs boost applications and takes more hp to turn.
Good luck.
