Just curious as to what pullies you are running and where you are seeing 12psi with your YS. I'm not seeing 12 until about 5600 with my 8"/3.33" pullies. I'm thinking about going with the 3.15" s/c pulley to bring up my boost down low a little quicker. Thanks.

Just asking, why not consider going to the 3" pulley like the one that comes with the renegade kit. I bet that will work for you as well. Would give you numbers but it will be a while yet before I have mine together.

That's true. I could try that and just shift at 6000 or lower until I get a real block. Right now I seeing about 12psi@5600. I wonder how much more the 3" pulley will make?
I run a 6.75" crank and 2.75 or 3" blower pulley. I don't see 12 psi until 5500 or so. I shift at 6100, and go through the traps at about 6400-6500. I can't remember what the blower pulley is, but it is the renegade kit that came with the 8" crank pulley and was supposed to make 22 psi.
