Here is the Bad Boy LSA that is going into Lou's Change. It is a CTS-V spec GM crate motor. After mock up it will be sent to Lingenfelter Performance Engineering for them to work their magic on it. Heads, cam, porting, pulleys, tune, etc. are all part of the Lingenfelter plan. The goal is gobs of torque and over 700 reliable and trouble free horse power.
You will notice it has the CTS-V top hat on the supercharger.
We're hoping to go with the new ZL1 top hat because it has the intercooler lines coming out the front, an improved heat exchanger brick inside and a shape that improves air flow overall (according to the GM literature).
In addition, the intent of the Lou's Change concept is to include tributes to the ZL1 vs. than the CTS-V. Hopefully the ZL1 top hat is going to fit under the stock SS hood.
Here are GM pictures of the parts used in the CTS-V spec LSA motor and the ZL1 spec LSA motor. You can see the differences in the supercharger top hats.
The CTS-V has rear exiting intercooler lines and a profile that slopes down in front.
The ZL1 has front exiting intercooler lines and the profile does not slope towards the front.
The Detroit Speed headers were ordered to make sure everything would go together as a totally engineered and proven system with minimal surprises. Yes, they are expensive but look at the craftsmanship. They are works of art in my humble opinion.
