Inline Booster Pump - Stewart's inline booster pump is intended for vehicles that experience overheating problems in low RPM situations. Since mechanical water pump speed is directly linked to engine speed, overheating becomes a major problem in situations such as parades, cruises, and stop-and-go traffic. The inline booster pump solves this problem by working in conjunction with the mechanical pump to create constant added flow to the engine block; the pump has been proven to increase flow by more than 300% at idle!

These pumps are currently being used by NHRA Pro Stock Champion Warren Johnson and Kurt Johnson by Dart Industries, and Jim Yates — as well as road racing American Lemans and SCCA World Challenge.
