Lingenfelter 2009-2014 CTS-V High Capacity Intercooler Fan Kit
DECATUR, Ind. – Lingenfelter Performance Engineering announces the availability of a high capacity aluminum intercooler heat 
exchanger and twin electric fan kit for the 2009 – 2014 Cadillac CTS-V (part #L320030709). The kit replaces the factory intercooler and is designed to provide improved intercooler fluid cooling.
“Our intercooler improves airflow to the engine radiator and reduces fluid temperatures, which, in turn, improves engine cooling and increases horsepower,” said Mike Copeland, vice president and general manager, Lingenfelter Performance Engineering. “The high capacity heat exchanger can be used with the stock or higher output intercooler fluid pumps.”
Maximizing the fluid cooling capacity, the intercooler features an innovative front-to-back, double pass design. The large size provides increased fluid capacity, and a larger cross section provides room for two, heavy-duty 11-inch Spal temperature controlled, two-speed fan assemblies.
“An optional fan and intercooler pump manual override kit (part #L300180000, sold separately] allows the user to manually override the fans and intercooler pump. Beneficial to drag racers, the override allows the intercooler pump and fans to be used to cool the intercooler between runs,” said Copeland.
Lingenfelter TBRC-001 Temperature Based Relay Controller
The Lingenfelter high capacity Cadillac CTS-V kit includes the TBRC-001 control module (part #L460220000) which is designed to control two relays based on temperature sensor readings. This module independently activates the relays for the twin fans and the intercooler fluid pump. Thus, the fans are only on when needed, providing quieter operation.
The TBRC-001 can also be used to activate intercooler water spray based on air temperature or alcohol injection based on intercooler temperature.
The included wiring harness has provisions for optional manual relay override controller with time delay. This allows intercooler coolant to circulate and run the fans after shut down to help reduce supercharger temperatures in between runs.
