If you own a 2009-15 Cadillac CTS-V or an LSA swapped vehicle, chances are at some point you will want more power. An easy way to accomplish this task on any supercharged engine is to simply crank up the boost. While this process sounds simple enough, you might cause yourself some headaches if the proper measures are not taken with the factory CTS-V supercharger.
The CTS-V OEM brick, housed inside the blower, is designed to handle a stock boost level of 8psi, which means that if you change the pulleys to increase boost, you jeopardize the brick’s integrity. As you increase boost levels on an LSA supercharger, two things happen. The factory brick is exposed to more pressure naturally, as well as a higher thermal load. These two conditions will cause the coolant end tanks to cave in and can lead to even higher air temperatures and internal or external coolant leaks.
Lingenfelter Performance Engineering (LPE) now has a solution to this problem with its reinforced intercooler brick. The reinforced brick allows CTS-V owners to increase boost levels without the worry of failure. These units are new GM take out cores that have 6061 aluminum end plates, which are welded on the ends of the brick.
The company states, “Our Reinforced Intercooler Brick delivers a product that is substantially stronger than OEM Factory standards, enabling the use of increased boost levels thought aftermarket pulley combinations. The factory GM intercooler “brick” was designed to handle stock boost levels (8 psi), so with increased boost levels that are produced with aftermarket pulley combinations, it can break down the integrity of the factory brick. Lingenfelter Performance Engineering offers this reinforced brick to address the weakness of the OEM design.”
