it all depends on how much power you're running, or more importantly your fuel requirements.
get it on the rollers and see if it can cope.
mine did fine on my zvh for a bit till i upgraded injectors to 630cc ones and whacked the boost up to 23psi, so i changed to a 979 pump just in case before i did the later, only flows 165litres per min or something like that, but better than the 4wd cossie pump which only did 130litres per hour.
