I maade 436rwhp and 901tq with a 60mm HX40 and my EGTs were about 1200 post turbo(probably 14-1450 pre) so I would say 450 hp is the reasonable max, maybe a toasty 500, but thats going to REALLY shorten its life. HX40's are already handicapped with the small shaft that is prone to snapping the first time you bark the turbo hard.
