The appropriately titled “Boost” family of camshafts from Howards Cams is perfect for your boosted Gen III/IV LS-series 3-bolt engines. And there isn’t a form of boost that isn’t covered: supercharged, turbocharged, and even nitrous oxide. These camshafts promise improved performance and dependability since they are designed with specific requirements for boost.
The Boost line of camshafts are available as just camshafts, or packaged with a set of lifters.
Howards Cams’ “Boost” series offers more than just a single cam to match these power adders. Instead, numerous camshaft options are available for each boosted LS application. This thorough methodology guarantees that an appropriate camshaft is accessible, regardless of the details of your build.
Turbocharged
The camshafts for turbocharged LS engines are made to maximize the efficiency of the turbo system. In a turbocharged application, a few different concerns come into play compared to a supercharged engine. One issue is the inherent restriction of exhaust flow caused by the exhaust turbine. Because of this “blockage” in the exhaust path, exhaust scavenging becomes essential in the design of the exhaust lobe. This is done to ensure that the turbocharger and the airflow within the cylinder can function to their full potential.
Supercharged
The Boost camshafts in supercharged LS engines help control the constant high-pressure environment that the superchargers produce. The cam profiles are engineered to sustain optimal valve control at elevated cylinder pressures, enhancing power delivery and combustion efficiency. This design improves overall drivability and smoother power curves, especially at high boost levels. In a supercharged application, you want to get the exhaust out as quickly and efficiently as possible. The goal is to lessen any pumping losses brought on by the increased volume of spent gasses in the cylinder that are attempting to exit the cylinder. By adding duration on the exhaust side, you essentially hold the door open for those gases to exit a bit longer.
Nitrous
With superchargers and NOS systems sharing similar features in the cylinders, the Boost camshafts for supercharged engines can be used in both applications. Howards Cams 190385-15 is a perfect example. With a lift of .612 /.638, a duration at .050 of 224 /234, and a centerline of 111, you get a cam best suited for a supercharged or a nitrous application, perfect for a street/strip build.
These hydraulic roller camshafts are offered in various profiles, from mild to wild. These units are precision-ground from race-quality cores, in-house, on dedicated cam-grinding machines. Each Howards Cams hydraulic roller camshaft is manufactured to the highest quality standards. Howards Cams has produced camshafts specifically suited to meet your performance goals.
