We've made easily over 630+whp on the 2860RS' (VG30DETT). The highest around 670 whp. This of course is done on race fuel. At a mere 12 psi on a VQ37 they can make 550+whp (with the right parts). On setups\turbos that are inefficient you'll see the boost go up but the power gains are minimal and start to drop off drastically, this is a good sign the turbo is pumping heat. Contributing factors are not only the turbo but the supporting modifications for example the piping diameter of the inlet, outlet, and exhaust piping as well as the VE of the engine.
