Part #: 8400C

The Race X Manifold is designed for high level motorsports competition and racing applications. The limits of the current Super Manifold are very high and more than enough for many enthusiasts, tuners, and racers. However, those looking to push their Gen 2 B58s to the maximum have been asking for more. Race X features a 25% larger core, additional parameter ports, and an optimized water flow system. The manifold can be used in either dual or single pass configurations and features a new front port that has been optimized for ice box setups. This is the most versatile and largest manifold available on the market and has been race tested on some of the fastest B58 powered drag cars in the world.

Features:

  • Utilizes a High Performance, Motorsports-Grade Bar/Plate Air-to-Water Intercooler Core - 25% larger than the standard Gen-2 B58 Super Manifold (CSF#8200) - 15 Rows of Water Cooling vs. CSF #8200 12 Rows and OEM 6 Rows
  • Core can be setup for dual or single pass: The -16 ORB bung on front water end plate can be used to adjust the flow configuration to single-pass and/or to be used with an ice-box setup. Includes CNC machined plug for dual-pass configuration
  • Designed in SolidWorks Using Computational Fluid Dynamics (CFD)
  • Integrated Air Divider in Inlet Tank Evenly Distributes Airflow Throughout the Core
