The A90/91 Toyota Supra is no doubt the hottest tuner car currently – both in terms of popularity in the performance aftermarket industry, as well as the amount of heat the car generates with increased power or when being pushed hard on the track or dragstrip.

As the world leader in BMW performance cooling, CSF has taken the lead in introducing a full-line of competition-grade cooling products and complete packages for the B58 engine (found in the Toyota Supra and many BMW G-Series models).

CSF has already released its most popular Front Mount Heat Exchanger for the B58 Charge-Air Cooling System, highly regarded as the go-to option in the industry to reduce intake air temperatures (IATs) and proven on the world’s fastest Supras.

As more vehicles start to become raced in competitive motorsports, the glaring overheating issues that plague this platform have become even more apparent. CSF has answered the call with the release of new High-Performance Auxiliary (Side) Radiators as well as a world exclusive Dual-Core ZF 8HP Transmission Oil Cooler.

Our full suite of high-performance coolers can now also be purchased as a complete package to solve cooling issues no matter the environment, and more importantly, help racers stay on the track longer and compete at higher levels, without cool-down laps or falling into “limp-mode.”

Don’t be fooled by other high-performance aftermarket options that utilize the OEM plastic rock guard. The OEM rock guard’s vertical channel design is specifically designed to only work with the tube spacing found on the OEM core. When the OEM rock guard is installed on an aftermarket radiator, it actually blocks a significant amount of surface area, detrimental to the intended performance. During CSF’s own R&D phase, CSF analyzed both the OEM and other aftermarket offerings and decided to take the extra step, redesigning the included rock guard to allow maximum flow to the radiator core, but still offering ample protection from small rocks and road debris – all proven on CSF’s in-house wind tunnel.

CSF’s new Auxiliary Radiator fits both the left and right side of the vehicle as a drop-in fit, requiring no modifications to install. Featuring CNC machined mounting brackets and OEM style “Quick Connect” inlet/outlet connections for a true plug-and-play installation that does not interfere with aftermarket performance aero modifications.

High-Performance Transmission Oil Cooler (CSF #8183)

CSF is the world leader in BMW transmission cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies. An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions – from road racing to the drag strip. During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use. CSF has the answer with our industry-leading transmission cooler for the A90/91 Supra and BMW G-Series’ ZF 8HP transmission. Installed in the world’s fastest A90 Supra  – Titan Motorsports Drag Race Supra (first and only Supra to reach the 8s in the 1/4 mile).

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.

CSF’s Creates the Missing Link to Maximum B58 Performance

The newer 2^nd 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.

World-leading Supra specialist and CSF R&D partner, Titan Motorsports, putting the new manifold to the test, along with the full range of CSF Cooling products for the MK5 Supra (5-Piece Ultimate-Spec Cooling Package).

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.

Local R&D partner and contender for both BimmerChallenge and the TRD Time Attack Series, Studio RSR, has been working with CSF and testing the new manifold off and on the track.

Reputable automotive website and performance part testing specialist, MotoIQ, was on site to witness and assist in organizing the testing to validate the accuracy of the claims made by CSF on the improvements and benefits of the upgraded manifold. The results were published independently by MotoIQ and are now available on their website – read the article here for more specific details on the increased performance of the CSF B58 upgraded intake manifold.
