EVOLUTION RACEWERKS | Sport & Race Series Oil Coolers
This oil cooler upgrade kit was thoroughly designed and tested after 3 years of development under the harsh conditions of our competition/time attack 135i and completely solves the dreaded limp mode on our cars. 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, our Competition Series Oil Cooler has kept our Time Attack 135i from seeing the dreaded limp mode issue due to oil temperatures. Regardless of conditions (ambient temperatures and track lay out), we 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 our beta testing program, we 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. Also, traditional oil lines would typically be routed so that the oil gets split to each of the oil coolers (each oil cooler handling 50% of the oil) due to ease of building the system and lower costs. Our Competition Series Twin Oil Cooler System however are setup in a "sequential" configuration. What this means is that oil travels from one cooler to the other thereby 100% of the oil goes through both oil coolers. Our testing have shown significant increases in efficiency and performance running a "sequential" configuration. Our new CNC machined oil filter housing adapter (included in the kit) makes this possible. Key Features:
Here are the results of some independent testing done by our customers: Independent Test 1 (Buttonwillow Raceway) Independent Test 2 (Laguna Seca Raceway) Kit Options: When the oil cooler box enclosures are used in conjunction with our optional ducting shroud kits, the oil cooler box enclosure actually seals and forces all the airflow captured by the ducting shrouds through the oil cooler cores. Improves the oil cooler's effectiveness and efficiency. The ducting shroud kits are available in aluminum or carbon fiber. These are model and bumper specific so make sure you order the correct shroud kit. We have both sport and race (dual) versions available. For additional information on our oil cooler kits as well as pricing, please shoot me a pm and I will be more than glad to take care of you  |
