CSF Charge Air Cooler Manifold 2020+ Toyota GR Supra

Why Upgrade?

The Race X Manifold is designed for high level motorsports competition and racing applications. The limits of the Super Manifold (CSF #8200) 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 asked 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.

Design & Engineering

The massive amount of research and development that went into the Super Manifold paid dividends when developing the Race X Manifold. That combined with all of the real world testing performed by race teams and tuners, CSF had all the information needed to begin the process of designing this brand new manifold. The main goals when designing the new manifold were to increase air flow and cooling capacity. Using Computational Fluid Dynamics (CFD) software CSF's team of engineers worked tirelessly on producing a manifold that would meet the demands of the most serious competitive drivers while offering the most features possible.

Biggest/Best Core in the Industry

Once you get into that 1000hp+ range on the B58, most aftermarket manifolds have reached their limits in terms of flow and cooling capacity. To resolve both limitations, CSF increased the size of the core by 25% over the #8200. The larger core has 15 cooling rows (vs 12 rows on the CSF #8200) and keeps up with the air flow demand while also increasing the cooling capacity.

Dual or Single Pass

CSF specifically designed the front water end plate of the manifold to allow for a single pass setup or ice box setup. This -16 ORB bung found on the front water plate is the largest available on any aftermarket B58 manifold (competitor's unit uses a -12 fitting). CSF has teamed up with industry leading fitting and hose experts Brown and Miller (BRMS) to optimize the water flow out of the front plate. CSF recommends using the following BRMS fittings with a maximum fitting angle of 120 degrees.

• BRMS: AC-16-M3-120 (Black)
• BRMS: AC-16-M4-120 (Blue)

BRMS is recommended by CSF because there are no flow restrictions on their fittings and are highly regarded as the best in the motorsport industry.

Top Feed Port Injection with Included Fuel Rail

The CSF Manifold includes an extruded fuel rail which attaches to the outlet side of the manifold. The -8AN fuel rail comes with a -8AN internal hex plug fitting. This allows you to run a returnless fuel system or a full loop setup.

• Fuel rail aperture for each cylinder is an optimized 7mm opening for compatibility with most commonly used high performance injectors
• CSF recommends using Injector Dynamics (ID) injectors for the best performance – the most commonly used injector for this engine has been ID model #1050.34.14.14.6 (qty 6)
• Anodized CNC machined injector hats (qty 6) are included in the supplied hardware kit to accommodate short height injectors aka "shorties"

Individual Nitrous / Methanol Injector Ports

A 1/8 NPT port on each cylinder runner can be used for nitrous or methanol injection. The CSF manifold allows for maximum spray control and even spray distribution throughout the engine.

A nitrous system set-up specifically for the CSF manifold is available from industry leaders Nitrous Express through Titan Motorsports.

Expanded Vacuum and Parameter Pad

CSF has included a port pad into the machining of the tank on the manifold inlet side. The ports can be used to measure additional parameters or as an additional vacuum source. The Race X Manifold has two additional 1/4 NPT ports to go along with the standard three 1/8 NPT ports. Each port can be plugged with the included hardware kit if they are not used.

Easy Access to Spin-Off Oil Filter

CSF incorporated a recessed design towards the back of the manifold that allows easy access to the spin-off oil filter. This means you do not have to remove your manifold every time you want to change your oil.

Air Inlet Divider

The inclusion of an air divider welded into the inlet side tank of the manifold is another exclusive feature of the CSF manifold. With the length of the manifold, the engineers at VF Engineering wanted to make sure that the volume and velocity of air was consistent to all cylinders. The inlet has an air divider to ensure the best possible airflow and equal cooling performance to each cylinder. Airflow to the back of the manifold (cylinders four, five, and six) should be equal to the airflow to the front of the manifold (cylinders one, two, and three) for the best possible performance.

Breather Ports for Inlet/Outlet of Water Tanks

Two -4AN ports are located on the top of the back water plate. These ports can be used to measure inlet/outlet water temps as well as used as breather ports to help in the bleeding procedure. The hardware kit includes the -14AN hex plugs. Please follow OEM BMW/Toyota bleeding procedure which takes roughly 15 minutes to complete.

Slotted Mounting Tabs

Positioning the manifold in the engine bay is fairly straightforward. However, it can be a little frustrating to get the bolt holes on the intake side mounting tabs lined up perfectly. After doing a few test fittings CSF realized this could be resolved by slotting the mounting tabs. This allows the bolts to be installed before final positioning adjustments and makes installation a bit easier.
