Can any1 tell me what effect the size of the restrictor washer in the pump has on water pressure. I have open loop on my PX and currently it has the water going straight to the IC which is showing signs of swelling I dont want to T the feed line like the stock setup as I like having more water going thru the cooler for lower intake temps.

So if I get a restrictor from a RXP think its bit smaller will that help or isit better to make the restrictor larger???
