I cant decide if I should put a second pump in my loop while installing these nozzles. I played around with the flow charts some, and still cant decide if getting more operating pressure would be beneficial or not. So here's what I got...D5 pump pushing through a Fuzion, EK G80 block, MCW30, and 2 EK Mosfet blocks. Add in 2 PA rads and 2 restrictive looking elbows to this mess. I'm kinda thinking more pressure for more 'squirt' might be a good idea here, so whatcha guys think...I have room for a second D5, should I or not? Are you guys with fairly loaded up loops finding the 1-2C gains those on CPU only loops are getting with the nozzles?
