Add Emissions-Legal Horsepower to Your LS Engine

You can add 30 to 47 emissions-legal horsepower to your Gen III or Gen IV by swapping the stock camshaft for a COMP Cams FSL Series Camshaft. The 50-state legal (CARB E.O. #D-279-13) camshafts require no valve spring updates or tuning required. Horsepower doesn’t get much easier.
How to Add up to 850 Horsepower to Your LS Engine

Adding 850 horsepower to your 1998-2014 GM LS is as easy as ordering a FAST Supercharger and Cam Power Package. The Power Packages are based on an Edelbrock TVS supercharger with an integral dual-pass intercooler and a COMP Cams Low Shock Technology (LST) hydraulic roller camshaft with a supercharger-friendly profile. FAST even includes matched valve springs and two supercharger pulleys—one for tuning and street performance and a smaller one for running on race gas or E85 at the track.
