The Bosch 1150 LPH PCA pump continues to be the baseline standard pump used in many liquid to air intercooler systems in both OEM and aftermarket applications. In the ZL1 system it flowed 3.6 gallons per minute (GPMP). This is the same pump used in the 2009-2013 Cadillac CTSV, Cadillac STSV, Cadillac XLRV, 1999-2004 Ford Lightning, Ford GT500 and many other OEM applications. It is also the pump used in Magnuson, Edelbrock, Whipple and many other aftermarket supercharger kits. It is fairly compact, very reliable and has low current draw. It performs fairly well against an outlet restriction but doesn't flow as well as some of the newer, higher output pumps that are available. This same pump has existed for well over 10 years without any major design changes.
