CSF NEW CSF Gen 1 B58 Charge Air Cooler Manifold 8300 8300B 8300C

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.

Disclaimer:

CSF pressure tests each #8300 manifold at 60-70 PSI for a period of 2-3 minutes during the Quality Control and Inspection process. The CSF manifold is not designed to operate above 60 PSI. Any users who chose to operate their vehicle with the CSF manifold over 60 PSI does so at their own risk. Operation at these pressure levels will void the CSF Limited 2 Year Warranty.
