Default P1sc-D1sc swap ???

Does anyone know if they use the same cases?

Wondering if I could send my p1sc to ATI and have them swap in a D1sc impeller? Or do I just have to buy a d1sc head unit.

Does anybody have prices to upgrade?

Anyone have flow comparisons between the two? Flow vs impeller speed.

They use the same case. The only difference is that the D1SC uses a bigger exducer.

The last time I checked it was like $1000 to have them upgrade a P1SC to a D1SC.

I think the D1SC will flow about 2psi more at the same speed over the P1SC.

Is the exducer the part closest to the impeller on the discharge side, or closest to the the discharge tube itself? (hope that makes sense)

We have a comparison between the P-1SC and the D-1SC in the LS1 Supercharger section of the site (it doesn't cut/paste to good here). We get $979. for the upgrade while it's about $1100. through ATI. The turn around time is usually aboyt 7-10 days depending on how they are doing with production.
