I already have a GT2871R with a 0.64 A/R V-Band turbine exhaust housing. The 0.86 would be too much for my setup, so I might try a 0.72. From the chart, can someone explain how the 0.64 vs the 0.72 housings compare and how it will react on the street?

The 0.72 seems like it might perform just a little bit better.

 

At 28psi youll be close to 15lbsmins per min. Unless 1bar equals is actually 0psi for charting purposes. I cant remember but it think that hows the one english guy explained it to me one time. If thats not the case, then at 28psi youll be close to just under 17.5lbs per min

 

Anybody else with a different angle on this?
