can you guys give me the low down on the differences in application between a P1sc and D1sc.
what strengths and weaknesses can i expect between the two when bolted onto an ls1.

ive ot a full bolt on 99 camaro and recently got a great deal on a p1sc headunit and id like to get 550rwhp with 317 heads and a blower cam using this headunit. can i do it or do i need to send it to procharger and have them upgrade it to a d1?

from what i have learned while looking into procharger's, both will be able to do the same to an extent, but most people go ahead and just get the d1 since u can get more out of it.

P1 will easily get you to 550

As has been posted, the P-1SC can easily get you to 550 rwhp. The P-1SC usually comes in the smaller 6 rib configuration, which is more prone to belt slippage than the D-1SC. Besides having a narrower belt, the 6 rib kit comes with a 6.0 dia crank blower pulley, where the eight rib kit comes with a larger 7.65 dia crank blower pulley. The larger 7.65 crank pulley means you don't have to use as small of a pulley on the blower to make the same amount of boost as you would with the smaller 6.0 crank pulley. A larger pulley on the blower means you would have better belt wrap which gives you less problems with belt slippage.

The P-1SC kit also come standard with thinner 3.5 inch twin intercoolers. The D-1SC kit as of 2005 or so, comes with thicker 4.5 inch twin intercoolers.

If you are looking to only make 7 or 8 psi of boost, the 6 rib kit will work just fine as long as you keep the blower belt tight. I used one for several years at 7 psi of boost without any problems. Bob

ok man i ran my old P1 for about a year and this is the thing with boost, you will alsways want more, so if you have the money just go ahead and send it in to have it up graded, but have the $$ to get everything else done that goes with it, you will need to build the cat to support the blower not the other way around, fuel, rear end, trans, motor. All of it comes into play and if you dont have this stuff then you will more then likey brake a lot of stuff and that keeps you car down for a bit, theses are thing i did not know when i first got started and is something i try and tell all the "new" guys to FI it cost a LOT but is worth it in the end.

my car is already a pretty nasty full bolt on car with ported heads and mean cam so all the other upgrades have already been done ( rear end, trans, suspension,etc.).

i bought just the headunit with no pulley attached and no piping or IC so i will be piecing it together, can i put the larger 8 rib and 7.65" pulleys from the D1sc on it?

thanks for the help guys

then you need to get a D-1

I'd def. go ahead and get the D1SC. There will always be room to grow unless you just want 700+hp right off the bat lol.

The P-1SC and the D-1SC both use the same housing, so yes, everything that works on the D-1Sc also works on the P-1SC.

Not to thread hijack, but how much would it cost to upgrade from the P1SC to D1SC if you were to send it in?

Approx $1300.00. Bob

part of my original question is what are the differences between the two? and what i mean is, does one make power sooner then the other or does one stop making power at a certain rpm; what are the limiting factors between the two.

what is the max i can take the p1sc to?

id like to know in order to help me decide on the cam i want to use. if the SC'er doesnt start to make power till 3000rpm knowing that i can spec out a cam that will get me off the line pretty well until the supercharger kicks in. or whatever the case may be.

Some of you guys need to read the thread before replying.. He already has a P1! He is wanting to know the differences. And I'm gonna tell you a different answer than everyone else too. Stay with the P1. I got 630rwhp out of my old forged 346 with stock truck heads and a speed inc SC2 blower cam. Do a little searching here and you can find nice threads like these to help you out on finding answers to your questions. https://ls1tech.com/forums/forced-in...rocharger.html

Once you have met your goal (which is EASILY attainable with a P1) don't mess around on wasting money on "just" stepping up to a D1. By that time, I bet you will be ready to stop playing around and step up to an F1!

for that money I agree with Chevychad. when your ready to step up sell the P1 and buy an F1
