If you’re looking for horsepower/torque levels from your SS Sedan beyond what can be achieved naturally-aspirated, then look no further than our Positive-Displacement supercharged performance packages! Our positive-displacement supercharged packages start with just the install of a basic Whipple 2.9L supercharger system with our recommended cooling and fuel system upgrades to support the added power. We also offer more power and sound with a longtube header system on the Stage 2 package. If you’re still looking for more performance, our Stage 3 package adds in a performance camshaft kit upgrade, as well as a set of CNC ported cylinder heads with upgraded lifters and head studs in Stage 4. For our die-hard racers, or those who want to produce a higher power level than the LS3 bottom-end can provide, our Stage 5 package includes a dyno-tested 416ci stroker engine combinaton from LME using a forged rotating assembly and E85 flex fuel system for a maximum power potential! All of our performance packages are 100% customizable to meet anyone’s exact needs, so make sure to contact our sales team to see what other upgrades may be available to help in achieving your goals.
