What brand fan is this using?

Benefit would be space - usually need slim fans for turbo installs. I don't think it would benefit someone NA with a stock rad.

They say it in their first post that they are using their own fans.

@Mishimoto any updates to share?

Correct this is for the front mounted Turbo guys. Its already been proven at the track the stock cooling for coolant is fine. Just need an oil cooler for track duty.

As noted by xxscaxx, a slim profile will be the primary benefit of this product. Cooling performance will be similar to the stock shroud setup.

August, faster that I thought. Whenever the pre-sale starts, sign me up! I also realize August is an estimate. I am going to wait to install my radiator until I get the new shroud.

Thanks Max! We should have a more concrete date once our final prototype has been tested.

We are utilizing two of our 12" electric fans. Check back next time for a look at the fans mounted to our shroud! We will also be constructing the overflow tank mounting points in the next portion of this R&D series.

Thanks for chiming in!

Not at the moment John! We should have an update within the next 1-2 weeks regarding the overflow tank accommodations.

I already have your Mishi radiator installed on my FR-S... so hoping that when this product is shrinkwrapped for sale.. that the install will not require taking the radiator out. Am I wishing for too much? Thoughts?

Thanks for picking up our radiator! Radiator removal is not required to install this fan shroud setup. Coolant will not have to be drained. You should be just fine! Additionally, we will be putting together a video installation guide highlighting the process.

Thanks for the interest!

Project update! Check it out below.

Keeping The Twins Cool! Mishimoto’s BRZ/FR-S Plug-N-Play Fan Shroud R&D, Part 2: Prototype Completion

We’re back for some more fan shroud fabrication! The last portion of this series highlighted the beginning stages of initial shroud design. The BRZ/FR-S uses a fairly unique overflow tank that mounts directly to the factory fan shroud. This is our first target for part two of product design.

Overflow Tank Mount Fabrication

This tank has two upper mounting points which use a bolt which passes through the tank material and into threads on the shroud. We utilized round stock aluminum which was cut to the proper length, drilled, and tapped for the appropriate factory bolt. These were then welded to the shroud in a position that would place the tank in the exact location as when on the stock shroud.


Welding overflow tank mounting points

The lower mounting point for the tank accepts a peg which is located on the base of the overflow tank. This peg slides into a hole to secure the tank, providing three locations for support of the tank. We fabricated our bracket and welded it to the shroud. We now had our mounts complete!

We then bolted the stock overflow tank in place!

We then mocked up our electric fan on the shroud. As noted previously, we are using two of our 12” electric slim fans to cool the FA20.

Prototype Installed

Now that fabrication was complete, we bolted our fans to the shroud and dropped it into place within the engine bay of our test vehicle.

The overflow tank is positioned quite nice with our shroud.

The hose also mates up properly with the factory coolant fill neck.

Fan Shroud Testing!

Next on our to-do list was to determine the cooling ability of our fan setup. We needed to ensure this system produced similar airflow to the stock fan setup and therefore equivalent cooling during idle conditions.

To check both the stock shroud and our prototype, we installed our in-line sensor adapters in both the upper and lower radiator hoses.

These were then installed on the vehicle to capture pre-radiator and post-radiator coolant temperatures.

We then ran each setup at idle for an extensive time period in order to verify our design. Temperatures were monitored and observed with each shroud system.


Testing Mishmoto prototype fan shroud

After evaluating the data, our prototype unit performed admirably. With the dual 12” slim fans, we were able to hit our performance targets in terms of fluid temperature regulation. We have no doubts that this setup will efficiently control idle temperatures in any environment. This is the last verification needed for this project, and we are now prepared to launch the manufacturing process for our BRZ fan shroud kit.

Discounted Pre-Sale

As with many of our new projects, we are preparing to offer a discounted pre-sale for those interested in picking up one of our kits. Keep an eye on this thread for more details!

Thanks for reading!

Great looking stuff

Since I had started my build way before your radiator was out I have a koyo rad installed as that was all that was available at the time.

What are the chances that this shroud will work with the koyo rad??

If so interested in the pre sales info
