ok, revised results!
I dont know what's going on with Ropers graph, maybe the cams need sorting but i'd expect more than that from a GTX. Sonny's is still mightily impressive spooling but Colin has a huge powerband compared to the rest of us which will translate well in the real world i should imagine.

TD05 - DannyGTI
