So here is the graph rerun with your new pulley info. The 928 mactches much closer at the higher rpms now. I would also guess that your more direct design and shorter piping helps get 3 psi early on. Love to see other logs of 'standard' setups.
I also added in 2 different pulley on my blower. Good example of how pulley size is irrelevant when making boost. You have to spin the impeller at a certain speed to get X amount of boost, regardless of pulley. Just depends on how early you want the boost.
Another interesting note is that even with a smaller pulley, you still do not gain more boost in the low rpms. Differences only show up at 4000+ engine rpms. Again, not surprising based on centrifugal design.

I have never taken off the volute on an actual 350z Vortech kit so I am unable to tell you how long it would take to do this on your car for example.
It will fit any car with a Sc-Trim or S-Trim. Not the Si though
In regards to alot of work. It was a bunch of work but it was a blast to make and design. I don't feel that I have limited my peak power yet on my car since the power never started to fall off like you see in high rpm's. The biggest benefit is that I have a ridiculous amount of belt traction which is the limiting factor on the Vortech kits.
8ribs+belt driving just supercharger+tensioner+200+ degrees belt contact= no slip!
Not to mention a better impeller and the fact that my crank pulley is larger that the stock one means I can run a larger pulley and get way more boost than normal.
I can also still install an air/water intercooler with ease that could support way more horsepower!

Other Info before from Quamen said it would only work with the V-1

any news on this? i wouldn't mind giving this impeller, high strength bearings, and a boost limiters a shot.
I want more down low! Stupid v8 muscle cars are killing me off the line!

No news from me since I now switched to a custom ST. Other than that it is what it is. A great option for those looking for minimal down time (as in hours) with results that would place you somewhere in between the capabilities of an Si trim and a T-trim. It gives you more boost at lower boost levels and even more boost at higher boost levels.
