LMP Supercharger Expansion Tank

The LMP Cadillac CT5-V Blackwing Expansion Tank (LMPBWET) is engineered to address the critical need for intercooler temperature management on high-demand LT4 platforms, especially during aggressive street driving, drag racing, or track use. Designed and manufactured in-house by Late Model Performance, this expansion tank significantly increases cooling system capacity by adding approximately 2 gallons of coolant volume. This increased coolant volume directly translates to improved thermal stability and a greater resistance to heat soak. For owners of the 2022-2026 Cadillac CT5-V Blackwing, the LMPBWET helps maintain more consistent performance from the supercharged LT4 engine by better managing heat buildup, particularly in tuned or modified applications. The kit includes all necessary hoses and fittings for a complete setup. This expansion tank is an ideal complement to other cooling upgrades, such as the LMP Blackwing Heat Exchanger, for enthusiasts seeking to maximize intercooler efficiency. The system is built in the USA by Late Model Performance.
