Because of the additional modifications, including cylinder heads and a camshaft, the manufacturer’s tuning software wasn’t sufficient for this project. A custom tune was created at Stenod Performance and the Corvette delivered 508 hp and 439 ft-lbs of torque at the rear wheels through an automatic transmission. This was on a Mustang dyno that typically […]

This chapter offers in-depth looks at the two basic types of bolt-on supercharger systems: Roots/ screw-type compressors that replace the intake manifold and centrifugal systems that mount to the engine’s front accessory-drive system. Both systems are typical in that they are delivered with all of the components and hardware required for installation, including fuel-system upgrades […]

This chapter discusses peripheral modifications that are commonly performed to support them, including fuel system upgrades, spark plug selection and the process known as “pinning” the crankshaft and balancer. For the most part, the factory cooling system on LS-powered vehicles is sufficient to support bolt-on power adders. In fact, at low speeds and part-throttle conditions, […]

Swiss engineer Dr. Alfred Buchi is credited with developing the first exhaust-driven turbocharger, sometime around 1912. By 1915, he published a proposal for employing a turbocharger on a diesel engine, but the idea was mostly ignored for the next few years. The first real world applications were in aviation, where turbochargers helped aircraft engines build […]

Superchargers come in many different shapes and sizes, but they are related by a common attribute: They generate boost pressure via an engine-driven mechanism. Typically, superchargers are driven by a belt connected to the crankshaft.   This tech tip is from the full book, HOW TO SUPERCHARGE & TURBOCHARGE GM LS-SERIES ENGINES. For a comprehensive […]

In general terms, and assuming everything else is equal, an internal combustion engine with larger displacement flows more air than a smaller-displacement engine. The engine with the greater airflow makes more power.   This tech tip is from the full book, HOW TO SUPERCHARGE & TURBOCHARGE GM LS-SERIES ENGINES. For a comprehensive guide on this […]
