Evolution Racewerks - Competition Series Front Mount Intercooler Kit - BMW E89 Z4 sDrive35i
The wait is over. With over a year of development and testing on a stable of test cars in different racing conditions, we're proud to introduce our new Competition Series Front Mount Intercooler (FMIC), the ultimate intercooler solution for your M135 and M235i!
- Large 20"x5.5"x6" (26.5"x5.5"x6" with end tanks) High Density Bar & Plate Construction Intercooler Core
- Cast end tanks for improved durability and internal flow characteristics.
- Mirror polished finish on intercooler assembly and piping.
- Optional Type III Hard Black Anodizing (for stealth) finish on intercooler, end tanks and all piping. Hard anodizing helps improve durability of intercooler fins against damage from road debris (rocks).
- Complete all aluminum intercooler piping, replaces all OEM rubber hoses with hard piping for improved throttle response and faster boost spool up.
- Impoved intercooler inlet and outlet pipes for better flow characteristics.
- Intercooler piping features beaded ends, silicone "hump" hoses and T-bolt clamps to prevent intercooler piping from coming off from boost.
- Maintains ALL factory components.
- Includes all hardware needed to install.
- Developed under the harsh conditions of racing on our 135i Race Car (same engine as Z4).
- Limited Lifetime Warranty.
Independent testing (by customers and shops) throughout the years have shown that time and time again, our intercooler cores have outperformed our competitors. We've even had competing companies utilize our intercoolers for competition instead of their own! The independent test data below shows that our FMIC is so efficient in cooling that it has cooled intake air temperatures (IAT) to almost ambient (outside) temperatures. We also did extensive testing on the proper size to use to effectively cool the hot charged air as well as fight off heatsoak (when the intercooler cannot transfer heat away faster that the heating building up from the hot intake air). Heatsoaking is not an issue at all as shown by the consistency of the IAT staying in the same temperature range throughout the WHOLE RPM powerband. Also, our FMIC recovers so quickly after a full throttle pull that once you shift, it recovers completely. This is why pull after pull, our FMIC does not heatsoak. Beat on it all day long and the IATs will consistently stay the same. Our Competition FMIC is just what it is called, designed for competition. Other brand intercoolers may be adequate for short period pulls like the 1/4 mile (with hours between runs to cool down). Our intercoolers are designed to withstand the rigors of harsh racing conditions like road racing where you are at full throttle for long periods of time, sometimes behind other cars blocking direct airflow needed to cool down your intercooler. With countless test and competition laps around our local racetracks in 100+ degree weather, heatsoak is not a problem on our 135i Time Attack race car. With it's size and ability to support over 600hp, it is most likely the "last intercooler you will ever buy".
One of the most overlooked aspect of intercooler design is the intercooler end tank and piping. Having shorter and less bends on the intercooler piping will promote better internal flow. This helps in reducing turbo lag, increase throttle response and faster boost spool ups. An intercooler end tank must be designed to channel and distribute air coming in from the inlet efficiently throughout the intercooler core. Our end tanks are designed to promote smooth internal air flow. The cast end tanks allow us to have nice smooth radius on the inner edges of the end tank, causing less turbulence.
One of the first things we noticed when we started development of our Competition Series FMIC for the F Series Chassis cars is that there is much more space behind the bumper cover compared to the older E Series Chassis cars. Without any major space restrictions, we chose to move the intercooler forward from the factory location. This allowed us to have an intercooler with more frontal surface area and more direct airflow without having to sacrifice internal airflow with an odd shaped end tank. Our test data on this design showed improvements in both IATs and ability to fight off heatsoak. Another added benefit of moving the intercooler forward is that now, intercooler sits more aggressively behind the center bumper cover.
The Competition Series FMIC comes standard with a brushed finish. We also offer and stock our intercooler applications with a polish finish or our Type III Hard Black Anodizing for the guys that want the stealthy look. With the Type III Hard Anodized FMIC, it is very hard to tell there is a FMIC on the car. Most of our customers with the Type III Hard Anodized FMIC comment that unless you know there is a FMIC on the car, nobody notices it. Another added benefit of the Type III Hard Anodizing is that it makes the intercooler fins harder and stronger, which makes it less prone to getting bent/damaged from road debris like rocks etc... We opted for the Type III Hard Anodizing over the Type II color anodizing which is only asthetics for this purpose only (even though it cost us considerably more to anodize Type III than Type II). We started using the Type III Hard Anodized Black finish on our rally car customer's FMIC's years ago. Rally cars go through tremendous amounts of abuse and it was quite common to take hits on the intercooler from debris on the course. In fact after 1 event, we would often see a large portion of the intercooler fins bent (killing efficiency) and fixing them was after each event was quite tedious. After the Type III Hard Anodizing, we notice a big difference as there was considerably less damage. Even after hits and even accidents, the FMIC could take more abuse than before. Testing has shown no noticeable ill-effect from the Type III Hard Anodizing on performance (regular spray paint etc... has shown ill-effects on performance). Eventually, we started utilizing the same Type III Hard Anodize Black on our street cars and now on our FMIC applications.
