I had those 595 that were 265 wide and I'd spin them up easy in second gear with 285 rwkw when running the Gtr in rear wheel drive..
Like stated before it has more to do with the power delivery, I had nismo gt lemans turbos that were plain bearing and would lag then come on hard, where as my mates -9 turbos with 280 rwkw doesn't feel as violent comin onto boost
In the wet I could spin all 4 265 down the highway in second
