Billet Specialties displayed its new line of LT supercharger lids at the 2024 PRI event. This new lid is designed to enhance both the aesthetics and performance of LT4-equipped vehicles. Scott Sandoval, Product Manager for Billet Specialties, highlighted the company’s focus on addressing the needs of modern muscle car enthusiasts.

“If you have a ’69 Camaro, you really don’t want your supercharger lid to say Corvette,” Sandoval explained, emphasizing the importance of vehicle-specific branding. Beyond aesthetics, the new lids offer a tangible performance boost of up to eight rear-wheel horsepower.

Dyno testing showed rear-wheel horsepower gains of up to an additional eight horsepower. Dyno results are available online.

The new LT supercharger lids come in two distinct versions, catering to different styles and preferences. The newer version, currently unnamed but referred to as the “new lid,” offers a clean, modern look. It is available in both raw and black anodized finishes, providing options for various engine bay aesthetics.

This version utilizes standard stainless fasteners with a Torx button-head and features 6061-T6 billet aluminum construction for durability and style. It also includes features like anodized black or raw machined finishes and Torx-head stainless fasteners. The lid utilizes the OE gasket for easy installation and replacement.

For enthusiasts seeking a more classic appearance, Billet Specialties offers another lid design. This version is designed to complement other LT accessories offered by the company, particularly their valve covers that are designed to clean up the engine compartment by concealing the engine’s ignition coils.

The development of these new lids stemmed from extensive research aimed at improving existing offerings in the market. With an emphasis on both form and function, Billet Specialties ensured that the lids not only look great but also deliver a measurable performance improvement.

The new LT supercharger lids debut generated huge interest among attendees. With a combination of enhanced aesthetics, proven performance gains, and two distinct styles, Billet Specialties‘ new LT supercharger lids are to become a popular choice for owners seeking to upgrade their LT4-powered vehicles.
