The turbo(s) are different but it will give me some actual data to run through some calcs with.
It starts to build boost at 2500 rpm and hits 20 psi at 4000 rpm. The turbos have a .63 exh. housing and i run 1 3/4 primary pipe.

LOL Am i having too much fun with this or do the rest of you guys do that too?
