Z33ART V-Mount SC+ 928M Billet Impeller=414whp
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
pretty sure the v1 and v2 housing are the exact same. v1 ust uses straight cut gears while the v2s use helical.
Si is an impeller trim so that has nothing to do with whether or not the 928+ impeller will fit.

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.
