[QUOTE="Stangra, post: 16593034, member: 193061"] I'm not sure you can expect to see the same percentage of increase in flow. [i]If[/i] the pump capacity is undermatched to the rest of the system plumbing then doubling up will make an improvement, but at some point it's no longer the main weakness and gains from doubling up or using a higher capacity pump will not be as dramatic. The pump/s are still trying to move that coolant through the limited size of the hoses and restrictions at the I/C ports. Opening up to 1" or 1.25" hose and I/C ports will make a [i]huge[/i] difference though. You can see in the link below that even D.O.B's big POWA pump only produces 10 gpm with .75" hose & fittings, but same pump moves 30 gmp when opened up to 1.25" plumbing.
