The 4.385 stage 2 on the d1 makes 15. 4.75 made 12.

The math on the 5" says almost 12, but in practice I've seen about 10psi at stock redline, maybe a touch more5.00 pulley on stage 2 kit. Procharger said it's supposed to make 12lbs but heard it only makes around 10.
So with cat deletes 4.385 should do 14 I'm guessing5.00 pulley on stage 2 kit. Procharger said it's supposed to make 12lbs but heard it only makes around 10.
3.4 is the smallest Procharger makes for the D1SC?
Lol

Weirdest thing. This afternoon, since I was putting in my stainless clutch line, I went about hacking up my JLT oil catch can and with new hose and fittings plumbed a custom PCV route for my D1SC setup. Instead of using the two PCV inlets to the intake tube like the instructions (like I had) I ran the PCV from the passenger side behind the engine to the driver side PCV. Just before the driver side PCV, I put a 5/8" tee and dropped it down towards the strut tower, where I tied in the 3/8" vacuum line from the y splitter behind the engine. I then ran the single 5/8" PCV line from there to the oil catch can (with new 5/8" barbs on both sides) as a single inlet to the intake tube fitting before the blower inlet.Understood. Im keeping the ID1000s, I was told there would be a 30% restocking fee if I return them, even unopened and I pay for shipping. :tsk: Hopefully the Lund tune is decent enough to get me by or limp my car home from install. If its bad, Ill just get a local shop to do the real tuning on dyno.
Maybe I'm doing my math wrong, then. Isn't the stage 2 kit an 8" dedicated 8-rib crank pulley for the blower?http://www.928motorsports.com/services/selectingpulley.php
On the stage II it looks as though 4.0" is as far as you can go within impeller speed limit of 62K. 4.0 gets you 61.5K impeller speed. However there are guys who have over driven them to 110%.
