Mishimoto E46 M3 fan and fan-mount system This project was progressing toward the end of testing our electric fan setup for the E46 M3, which is shown below. However, we ended up taking a different route for this project. At this point, we still wanted to test the impact of our airflaps during speed driving. After a lengthy test, we were pleased with the results. We recorded inlet and outlet temperatures to see how quickly and effectively our fan setup reduced temperatures. We positioned the vehicle on the dyno, adjusted the fan controller, and kept an eye on the gauges. Our goal with this particular testing was to ensure that our fan could control and properly regulate idle temperatures for an extended time. Next, we installed the Mishimoto prototype along with our temperature sensors for data collection. To get started, we began removing the stock setup. Once we had a working prototype, we decided to perform some idle testing to see how well our single electric fan would perform on a mostly stock E36 M3. This unit is a traditional aluminum fan shroud with air flaps to improve core airflow at speed. When we left off last time we were exploring our first prototype design. Keeping The E36 Cool, Part 2: Second Prototype Last, we have mounted our fan controller to the driver’s upper corner, which allows the fan activation temperature to be adjusted to the owner’s liking.Ĭheck back with us next time for testing of this first prototype, and a look at our second idea! Additionally, we are designing an aluminum counterpart that will also function with our shroud (and the stock shroud). Our shroud is being designed to function with the stock unit. Next, we have incorporated a stock overflow bottle mount on the passenger side of the shroud. If our tolerances are too tight, this could mean big problems for your new electric fan setup. Bushings for the E36 engine and transmission mount can wear and cause significant movement of the engine. This provides greater clearance between the engine pulley systems. First, the fan has been offset to the driver side of the radiator. Check out a few images from the Solidworks design software.Ī few things to note on this design. So next, we created a 3D model depicting our plans for this shroud. Testing seemed positive on the bench (off the vehicle), but we also wanted to test this system on the road. We also set up one of our intercooler dyno fans, which achieves 30–40 mph wind speeds, to see the effect on the flap movement and airflow through the core. Check out a few shots during some basic bench testing. When closed, the fan can then take full advantage of the shroud and its ability to pull air through the radiator. For years we have been developing and releasing functional and effective aluminum shrouds, but once in a while we like to try something new to see if a positive impact is made on the end product.įor our first test we installed some air flaps on our shroud to allow airflow at driving speeds and then close when the fan is operating at a stop. Check out the process we took to bring you guys a slick fan setup!īefore even starting our design, we wanted to explore a few new features that could be included with our fan shroud. Swapping your antiquated mechanical setup for an efficient electric system is a great way to improve reliability, and even free up some power on your vehicle. To reduce vehicle downtime and expense, it would be wise to replace this component before failure occurs. That said, a fan failure can get quite ugly with shrapnel tossed around the engine bay, often damaging other components. The stock fan setup is certainly efficient in keeping your straight six cool. The mechanical fan is next on our list to be addressed. So far we have a few remedies – an aluminum radiator and a silicone coolant hose kit. ![]() ![]() This includes anything made of plastic within the system. Keeping the E36 Cool, Part 1: Initial Fan Shroud DesignĬooling systems on older BMW models have been recognized as a frequent failure point requiring regular replacement to avoid catastrophic failure. ![]() ![]() Check out our progress and testing on our blog, or posted within this thread. As noted in several other threads, we have been working through several design processes to bring you an awesome new electric fan conversion kit for the E36.
