I have used the billet 170 pump on 754 HP motors with sucsess and it is a great piece, but no way would I run motor and nitrous of it. Nitrous fuel pressure is so important, unless I have a monster pump like a A1000 I will never run a single fuel system. Personally, I have had good sucsess using the old noisey Holley Blue pump on the nitrous side. I like te fact you know it is on before you push the button.
There are fail safes, pressure switches, that will not allow the nitrous to come on without proper pressure. I have never hurt a motor on nitrous yet, and never run any of that stuff, just 2 gauges, nitrous and nitrous fuel pressure..
