if youre intent on running it dry... go ahead.. but like others have mentioned.. why? if its a working part.. why break it? i understand you have a replacement part for it.
also why is it noisier when you put fluid in? what kind of fluid is it? they topped my car off with regular clear PS fluid once and the system made a crapload of noise.. i had to flush it and put regular ol red atf in it to get it quiet again.. also if theres air in the system (ie you let it run dry then refill it quickly) it will make noise.
either way, good luck.. but i dont understand the point...
