[QUOTE="Catmonkey, post: 16041343, member: 124025"] The CWA 50 is rated at a max free flow rate of 30 LPM, which is just under 8 gal./min. The free flow rates are somewhat irrelevant, since all coolant systems are going to have some level of restriction and some volume of coolant it has to push. The Pierburg is said to flow 6.3 gpm at 8.7 psi. I pointed out these two graphs from the Linginfelter forum in my write up that are a lot more telling that free flow rates. The first chart is the actual volume Lingenfelter measured based on varying pressures of several different pumps. Here is that data graphed. [ATTACH]1525008[/ATTACH] Now what follows is the actual flow rates in a ZL1 Camaro employing these different pumps. Is the ZL1 intercooler system more restrictive than the GT500, I sort of doubt it based on the i.d. of the tubing in the GT500. It takes the McDaddy pump like the BW to increase the flow rate by a signifciant margin. The Pierburg has similar flow ratings to the ZL1 pump. Here are the results.
