I have the 84mm coming tomorrow to compare to the 7875. I'm curious if it truly will spool faster as they say and flow a decent amount more. Honestly if it just flows what a PT7675CEA does for less then half the price then I'll be happy.
I ordered the 84mm because the cast 78mm wheel didn't seem to keep up in the higher RPM's. Most I could get out of it was spike 26-27psi and then taper to 21psi above 6k RPM. It didn't have the top end charge the PTE7675 CEA did as that would hold 24-25PSI to 7k easily.

Restricted to what, about 850-900whp?

So I visited their website, and found a couple of things to be interesting. If they rate their turbos output at the crank, it definitely appears that they are sandbagging with the output numbers. They rate the 84mm turbo at 950.....but I'm using the 7876 and I'm making about 900 (crank) with a soft tuneup. I guess it's better to underrate...than to overrate. I also found it interesting that they are still using a .80ar compressor covet with the bigger wheel, seems they would have opened it up more to take advantage of the bigger wheel. Still seems to be a good value though. And found it even more interesting to see them using a Th350 in their test car....and running 9.0s.
