See this is where I'm at, I'm running a 7875 w/ a M6 and am trying to figure out where to go from here when I max out the 7875.
I'd like to go with a Borg or clone of some kind but wanna keep the fast spool for street shenanigans.
What were the specs on the S484 your buddy was using with his manual?

I wanted to know, do you guys consider this quick spooling? I’m cruising in third, punch it, downshifts to second.......

I think a lot of it is in the tune as to how they spool with a manual, some people do it right and others have laggy turds.

They need to marry that 84mm compressor side with the PTE clone 88's 83mm/.96 t4 turbine. It would sell like crazy as a 84/83 as the 83mm t4.96 turbine housing is much larger than the "normal" .96 t4 for some reason.
