Description

All the Features You Need to Push the Limits

CSF has had tremendous success with its Gen 2 B58 “Super Manifold” for G-Chassis BMW and Supra with over 450 units sold and counting (CSF #8200/8200B/8200C). Due to its industry leading design and proven performance, CSF has received countless requests to engineer its “Super Manifold” for the Gen 1 B58 F-Chassis BMW platform. Finally, the wait is over for Gen 1 B58 customers! The “Super Manifold” is now available for your BMW. You no longer have to settle for a lower quality product.

The Gen 1 B58 Charge-Air-Cooler Manifold has all the same features and specs as the lasted version of the CSF Gen 2 manifold. This also includes some additional improvements for a better fit and finish over the competition. You can read about the development of the CSF Gen 2 B58 “Super Manifold” in our original press release.

Why Upgrade?

With the Gen 1 B58 powered BMWs getting a little bit older, more tuners and enthusiasts are picking them for competition. This has greatly increased the demand for more motorsports grade products for more power and reliability. Many vehicles are pushing well over 600 horsepower and needing additional fuel and cooling to reach their power goals. The CSF “Super Manifold” is the all in one solution for proven performance and the largest feature set in the industry.

The OEM charge-air-cooler manifold for the B58 engine is adequate in cars with little or no modifications. However, it starts to really its weaknesses in cars that have bolt-on modifications, turbo upgrades, increased fueling (such as port injection), and performance tuning. In addition, the OEM intercooler system has been known to suffer from heat soak in demanding racing conditions such as time attack, endurance racing, drag racing, and drifting, as well as spirited driving on the street. This can cause the car to pull timing out of the engine due to high intake air temperatures (IATs). This can send the car into “limp mode” once temperatures reach a certain threshold. In high boost applications the OEM manifold is also prone to failing at the crimp on gasket joining of the core and tanks.

Design & Engineering

In development of the Charge-Air-Cooler Manifold for the Gen 2 B58, CSF conducted extensive testing on the dyno with R&D partner VF Engineering. This consisted of over 50 dyno runs on the same car, on the same day, in relatively hot ambient conditions (~90°F) comparing the performance of the CSF Charge-Air Cooler Manifold to the OEM. Both the CSF and OEM cooler went through roughly 25 back-to-back dyno pulls every 30 seconds to measure the performance of the car overtime, resistance to heat soak, recovery time, and the effect on the turbo system duty cycle. You can read all about the testing procedures and results on MotoIQ‘s website – read the article here. This in-depth and through testing sets CSF apart from the competition.

Summary of Testing

• Faster recovery of intake air temperatures
• ~30°F reduction of intake air temperatures (IAT’s) compared to OEM
• Less pressure drop compared to OEM core
  • Puts less stress on the turbo system, allowing more boost to be made at higher targets
• Avoided going into limp mode after prolonged demanding conditions, simulating motorsports use
• On a stage 2 car with bolt-on upgrades, making ~400whp (with no port injection), comparing dyno run 19 between CSF and OEM, an increase of ~26whp and 11wtq were achieved
  • The performance increase and delta between CSF and OEM will be larger as power is increased in the vehicle

Proven Design & Results

Because the CSF #8300 is the same overall design as the CSF #8200 with some small design adjustments to fit the Gen 1 B58, there is no question that it will perform. The Gen 2 B58 “Super Manifold” (CSF #8200) has been real world tested and proven in some of the most extreme motorsport competitions around the world. It has stood up to the rigors of the Pikes Peak International Hill Climb, Global Time Attack competitions, and Texas 2K drag racing, just to name a few. In addition, it has also been dyno proven on many vehicles pushing over 1000 whp. While there are countless features and details to show just how superior the CSF Manifold is, real world examples speak louder than words.

Studio RSR’s Supra

Studio RSR has spent a lot of time racing behind the wheel of their A90 Supra. Their initial focus was on time attack events like Global Time Attack. However, in 2023 they decided to take on one of the most difficult races in motorsports, the Pikes Peak International Hill Climb (PPICH). The car performed amazingly and the full 6-Piece CSF Cooling Package kept the car cool in the most demanding conditions.

• GTA Super Lap Battle – COTA 2022
• 1st Place – GTA Street Class 2022

Titan Motorsports’ Supra

One of the biggest names in Supra drag racing, Titan Motorsports has been a major player in the inline 6 world for years. They regularly compete in some of the biggest drag racing competitions in the US and know a thing or two about making a fast car. Their Supra is pushing over 1000 whp and has a personal best time of 8.18 seconds in the quarter mile.

CSF vs the competition and OEM

CSF isn’t the first company to offer a Charge-Air-Cooler Manifold for the Gen 1 B58. However, CSF is bringing the most sophisticated design and largest feature set to the market. Add that to the years of experience and a proven track record with the Gen 2 B58 Manifold, and you get the best possible product for your vehicle.

Not all cores are created equal. CSF uses a motorsports grade Bar/Plate Air-to-Water core that is double the capacity (100% larger) of the OEM core. In addition, it also uses 12 cooling rows compared to the 6 rows of the OEM. Two of our competitors both use the same core that is only 70% larger than OEM with an unpublished number of cooling rows.

O-Rings, Gaskets, and Thermal Spacer

Each intake runner on the CSF manifold is machined for the OEM O-Rings with the factory style “teeth” to secure them (exclusive feature). This keeps the O-Rings from falling out during prep and installation. This feature makes installation far less frustrating.

Additionally, the Thermal Rejection Competition Spacer acts as a gasket between the cylinder head and the manifold. The precision machining and production of the spacer creates a perfect seal on top of the insulation properties. Our competitor’s phenolic spacer does not meet the same standard forcing them to use aftermarket O-Rings in addition to the factory ones to create a positive seal between the manifold, spacer, and cylinder head.

Oil Filter Recess

CSF’s competitors also incorporated a recessed design towards the back of the manifold that allows easy access to the spin-off oil filter. However, CSF is the only company to account for the airflow issues caused by this recess. CSF Engineers designed and tested a counter balanced protrusion using SolidWorks CFD software. This protrusion sits above the recess to offset the airflow tabulations. This feature ensures smooth air delivery into the rear of the core for the best possible cooling.
