Speedmaster Introduces Chevy Gen V LT1 Downdraft EFI Intake Manifold System

Speedmaster® is set to unveil one of the company’s latest groundbreaking engine products at the 2023 SEMA Show – the Chevy Gen V LT1 Downdraft 8 Stack EFI Intake Manifold System. The completely polished manifold system will be entered into this year’s New Products Award competition as one of 30 new products from Speedmaster. 

This system is more than a visual nod to the classic Weber-designed induction. Designed to elevate performance, Speedmaster’s intake manifold system marries vintage manifold aesthetics with contemporary EFI functionality. Designed for quick throttle response through tight air/fuel ratio control, the Chevy Gen V LT1 EFI Intake Manifold delivers aesthetics and improved performance in one package.

Key Product Features:

  • Aesthetics & Function: Combines the classic look of Weber induction with modern EFI precision.
  • Versatile Performance: Designed for an LS3 engine block and operates seamlessly from idle to 7,000 RPM.
  • Precision Engineered: CNC machined from heat-treated 601 cast aluminum, ensuring durability and performance.
  • Optimal Drivability: Features a fully indexable eccentric cable pulley on the bell crank, striking the perfect balance between slow speed and full throttle.

Speedmaster’s unique linkage set innovatively integrates throttle stops, idle controls, lever arms, and a joiner/balancer, all fine-tuned with a single screw adjustment for perfect synchronization.

For performance enthusiasts, this product not only symbolizes a return to iconic car culture while introducing a level of fine-tuning previously unattainable with traditional systems.

With a U.S. MSRP of $2,450.00, the Chevy Gen V LT1 Downdraft EFI Intake Manifold System is a game-changer in the realm of fuel-injected intake manifolds in terms of budget, appearance, and function. 

To discover more about the Chevy Gen V LT1 Downdraft EFI Intake Manifold, visit Speedmaster at one of two locations at the 2023 SEMA Show. Speedmaster’s outside booth is located at #81020 in the Silver Lot. The location inside is in Racing and Performance in the Central Hall, booth #22753.
