How many 350z guys can you show me that made the swap to a C38R-112? I know of one and he gained 5psi with the same belt setup and harsh charge piping. He was running a pulley setup that was initially designed around an 81 and not a 112. They designed their kits with looking stock before performance so they had to smash a small intercooler inbetween the factory crash bar and the radiator shroud so it is undersized for these newer power levels....etc..

Actually, the terrible bends were part of the stage 1 kit, I had the original and it was a terrible design. The move away from that into a straighter pipe and the filter under the exhaust manifold was the compromise so higher boost to be reached. Not sure who has had a melted filter or intake issues but curious on that one, been running the 1.5 kit with the straighter pipe for many years with intake temps 5-8 above ambient in Texas summer with no issues.
Just like this forum I keep an eye on the 350z side and read up on all the builds I can find, not saying they were magical numbers made, just that the 350z guys got into the C38R already.
I never said you were producing this for high numbers, that was directed at another user here. I am happy to see another shot with a supercharger with the Rotrex because I think it provides the best power band for our car and real gains. The original response was with someone saying the 370z has not seen a Rotrex tested on this car, which it has for many builds with high success. Just as you said, in the early 2010 days 500whp was crazy high so the early SC folks hit 400-450whp and stopped and very few went after the high numbers until you brought a real kit (Stillen with A2A) to market.
