After 3 years of development, they re finally ready. Introducing Evolution Racewerks Competition Series Twin Oil Cooler System that solved the dreaded limp mode!
The 135i/335i comes from the factory with a small oil cooler with a core size of 8.75"x4.75"x1" (222mmx121mmx26mm) which comes out to 41 cubic inches of core. The Competition Series Twin Oil Cooler system features two Huge identical oil coolers 11"x8"x2" (280mmx203mmx51mm) with a core size of 9"x8"x2" (229mmx203mmx51mm) each. Each oil cooler comes out to 144 cubic inches which is 3.5 times larger than the factory unit each! Since there are two oil coolers, you have a combined 288 cubic inches of oil cooler core, over 700% more core than the factory oil cooler. Through 3 years of development and testing, Evolution Racewerks Competition Series Oil Cooler has kept Evolution Racewerks Time Attack 135i from seeing the dreaded limp mode issue due to oil temperatures. Regardless of conditions (ambient temperatures and track lay out), Evolution Racewerks have never exceeded 259F! This is in 110F+ track temperatures and wide open throttle pulls all the way to 6 gear (160+ mph). Through test cars used in Evolution Racewerks beta testing program, Evolution Racewerks are getting independently gathered, unbiased data showing the same exact thing.
Each Competition Series Twin Oil Cooler mounts to its own box enclosure. Louvers on the backside of the box enclosure ensures airflow through the oil coolers while protecting the oil cooler from road debris, especially debris kicked up from the front tires. During initial testing, Evolution Racewerks box enclosure had a big window (open hole) in the back for airflow. However, throughout the race season, it took so much abuse from rocks, tire and other debris kicked up from the front tires that Evolution Racewerks had to replace the oil coolers on Evolution Racewerks Time Attack 135i. Thus, instead of a big hole for airflow to flow through, Evolution Racewerks used louvers instead to protect the back side of the oil coolers. This effectively solved the issue without any affect on performance. Oil temperatures as well as oil temperature deltas stayed the same.
