Exterior wise, they're both the same but the D1SC headunit flows 200cfm more than the P1SC headunit...

internally, i believe the d1sc impellar is longer which makes it flow more. for $200 more for the d1sc, its well worth it

Is there an upgrade path from the P-1SC to the D-1SC?

Yes, you can send in your P-1SC blower and have it upgraded into a D-1SC, but it cost approx $1,400.00. Bob

good to know. I will consider this down the line for my P1.

The P1SC is legal in every state and the D1SC is not in California or something like that.

I am already starting to max a P1SC out on a stock motor. Buy the upgrade when you buy it the first time. Learn from my mistake. Mine will cost me $1400 down the road when I build a new motor....

I am pushing 5.25# with the stock 6 rib crank pulley and a 3.4" blower pulley. Started making 3# with a 4.10, got 5.1# with a 3.7, and then did a LS6 intake, TR blower cam, and 3.4" pulley, and got 5.25. Did alright powerwise (458/329), so it is flowing well, but I will max the blower rpmwise before I ever see 10# I will bet......

Here is a visual on the difference between the two.

Hm, doesn't look like there's too much work involved in getting the upgrade done and it makes $1400 seem a bit steep.

Ah well, the P1 is good for now

A better option would be to sell the P1SC, and buy a used D1SC. You would probably only pay $500 out of your pocket.

yea $1400 seams steep for 200cfm

But $200 for 200 cfm is a bargain! Get the D1 from the get go!!!!

When I order mine, I'll make sure to do it right the first time and buy the D1sc. I know the hp bug will get me and I'll end up maxing out the P1sc, so I'll fork over the extra 200 to save in the long run.

I wish I knew that beforehand - already have the P1

I hear you there I'm stepping up to a F1 here in a few days .

Skip the D1SC and go straight to the F1A

I would like to get a F1A now but it's kind of a hassle to sell my D1SC head unit.

The F-1A has a 5.40/1 step up ratio, where the P-1SC and the D-1SC have a 4.10/1 ratio. A larger pulley for the head unit would have to be made to allow an F-1A to keep the boost down on a stock bottom end. I have one customer who had a 5.50 pulley made for his GTO, which kept his boost at 7 pounds. The GTO kit has a 7.0 crank pulley though, where the LS1 F Body kits have a 7.65 crank pulley. What this means is that on an F Body you would need an even larger blower pulley made to keep the boost down. Bob
