The New “Super Manifold” for A90/91 Supra and BMW B58
CSF is proud to announce its most advanced cooling system to date – the new Charge-Air Cooler Manifold for A90/A91 Toyota Supra and BMW G-Series
(B58).
With well over 1,500 hours of design, prototype development, machining, and testing, CSF, along with partners VF Engineering (USA) and Custom Plenum Creations (Australia), has now brought a state-of-the-art CNC machined, high-performance Charge-Air Cooler Manifold to the B58 platform for Mk5 Supra and BMW models. This product solves what has been commonly known as a weak link of an otherwise impressive new engine platform.
With the larger and more efficient water-to-air intercooler performance, lower pressure drop across the system, included fuel rail, kit for top feed port injection, and several other industry-leading features, the CSF Super Manifold will allow B58 owners to maximize the performance of their vehicles and push the limits further than what has been previously possible with this new platform.
The OEM water-cooled charge air cooler intake manifold for the B58 engine is adequate in cars with little or no modifications, but starts to really show an apparent weakness in cars that have bolt-on modifications, turbo upgrades, increased fueling (such as port injection), and performance tuning. Also, 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), and then can cause “limp mode” once temperatures reach a certain threshold, as the vehicle’s ECU will cut power to protect the engine.
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, 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 bigger as power is increased in the vehicle
