why wouldn't they come close? they will go well past the 1k mark. mine now makes 750rwhp on pump gas, twin 61mm turbos, 14.5 psi, 10.5 a/f, 10 degree timing... lets just say theres more power to be had! my car has a VERY modified version of turbohorsepowers twin turbo kit. turbohorsepower ended up making 1200rwhp with twin 61's at 28psi on one of their customers cars and already my car is making more power psi for psi.
trust me, twin 61's are the way to go. plety of power to be had!
as a note, turbohorspower made just under the 1k mark with twin 57's.
