I know there are a ton of comparison threads out there on these two turbos, but I have yet to find any direct dyno comparison charts out there, anyone have any good charts for an EVO x gsr on 93 octane pump? I know the BBK flows about 51 and the Green about 54, but i'm curious to see what kind of power bands they and the power under the curve.

If you got some good dyno graphs for these turbos on an evo x gsr running 93 pump, please post them!

the bbx for the evo 10 has a 60 mm (inducer) comp wheel while the 4g63 bbk full has a 53.5 mm inducer so the bbx is much more potent than the 4g63 bbk full. conversely, the comp wheel for the evo 10 green has a 52.5 mm dia comp just like the 4g63 green. so the bbx is better compared to a red or black for power. its a pretty cool turbo. scheides has some nice dyno data on it.
