Why do i see alot of people getting the D and just run between 5-8PSI or even 10 since the P gets the same level of boost at lower RPM and keep it that way through the power band longer. Both will reach 30PSI and 32 for the D right? But from what i read, the P gives boost before the D right? Wouldn't the P-1SC be better for a heads/cam car or all bore 382CID car both with lower C/R because u wont be needing more than 14-16PSI right?

The D1SC is the best choice for any HCI car, stroker motor or all bore motor. The P1SC doesnt have the room to grow like the D1SC plus the boost capabilities of the D1SC are awesome.

The reason is that last year I ran the 3.2 pulley on my p-1sc and it made 7 psi. now I am running the 3.2 pulley on the d-1 and it makes 12 psi. so in reality you can run like a 3.8 pulley and get like 5-7 psi on the d1 and it wont be as tough on your motor. also the d1 flows 1400 cfm compared to only 1200 for the p-1

The D1-SC Has A Helicut Impellar With Curved Blades Versus The P1-SC Has An Cheaper Impellar With Straight Cut Blades. The D1-SC Is A Better Choice For The LS-1 Especialy If You Ever Plan On Doing Any Other Mods. The Curved Impeller Pulls Air In Faster Which Means The Boost Will Come On A Little More Agressively Plus Its Efficency Is Better. This Means That The Horse Power Per Pound Of Boost Will Be Higher Than The P1-SC, On A Higher Horse Power Motor. Although You Can Order A P1-SCH (The H Means It Will Come with The Same Type Of Impeller That The D1-SC Has). The Other Advantage In The D1-SC Is That It Will Give You More Room To Grow As Your Modifications Increase. (D1-SC 1400CFM, P1-SC 1200CFM) Almost All The LS-1 Cars We Do At My Shop Are With The D1-SC Except Those Who Are Needing An EPA Number.

Pretty interesting. If I go boost then it is the D1.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Not to make things more complicated but the P1SCH also has a helical cut impeller.

Jason at Golden West Performance has been telling people all along that the D-1SC is the way to go if you are willing to pay the extra three bills. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
