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).
All the Features You Need to Push the Limits
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 newer 2nd gen B58 engine, found in the Mk5 Supra, has already been proven to be an incredible platform for performance enthusiasts – taking the performance and motorsports industry by storm in just a couple of years since its release. In a short amount of time, performance enthusiasts have already started to more than double the stock engine output – now pushing through 700whp, 800whp, and looking into the elusive 4 digit 1,000whp mark.
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.
CSF conducted extensive testing on the dyno with R&D partner VF Engineering to ensure performance improvements before going into production with the new manifold. We performed 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.
- 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
On the outlet tank, each cylinder runner has a 1/8th NPT port which can be used for nitrous or methanol injection (a popular power modification on the B58 engine). 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 will be coming soon from industry leaders Nitrous Express.
A handful of cars at TX2K had blown their engines due to the way their nitrous systems were plugged into their vehicles. With the OEM plastic manifold, a single spray system is most commonly used as threading into plastic to insert an injector node is already very difficult to install properly. The single fogger system, more often than not, will create unequal distribution of spray in the engine, either giving some cylinders too much or too little spray. This will increase the chance of severely damaging the engine.
