Looking forward to seeing some customer cars pimping these blowers soon! They definitely steal the show when at a cruise-in with the hood popped.
The 78mm t-body inlet starts to choke at around 520 rwhp. When Ed offers the 90mm inlet option, it should be good for almost 600 rwhp and the case size becomes the limiting factor. I've had two similar setups, with both T-bodies.
348ci LS6, 9:5 CR, ported LS6 heads, 230/230 114 cam - 505 rwhp @ 9 psi boost
366ci LS2, stock CR, stock LS6 heads, 230/230 114 cam - 550 rwhp @ 5 psi boost
The additional cubes helped some, but I'm convinced that a 90mm t-body on the first combo would have made closer to 600 rwhp. It pretty much stalled at 505 no matter what we did. I would have also just left the CR in the 10.0 to 10.5 range on the first combo, if I were to do it again. Both cars had 1-3/4 longtubes with offroad exhausts.
Here is a video of how the 2nd combo runs:

The first combo was in my '69 Camaro, it ran 10s on a pro-touring suspension.
