Interested in purchasing our 2008-2014 Subaru WRX Top-Mount Intercooler? Check out more details on our product page linked below!
Nothing sets off a Subaru engine bay like a nice beefy top-mount intercooler. Not only does a big TMIC look great, but it is also instrumental for keeping AITs low and your EJ happy. For those seeking low AITs on a stock to mild build, an efficient top-mount setup is the way to go to avoid inheriting the pressure drop and lag from a front-mount intercooler. Not only this, but the TMIC prevents any road (or off-road) debris from damaging your heat exchanger. This is key for those who are involved in any rally, off-road, or rallycross events.
If you keep up with any of our social media outlets, you are likely aware that Mishimoto has been working to develop a TMIC for the 2008-2014 WRX. We are very active within the Subaru enthusiast community,

Finally, we made it to our day of testing! We had previously confirmed fitment and made a few minor adjustments to some external end-tank features to improve coolant flow and ease of installation. A member of E90post was kind enough to lend us his vehicle for this round of testing. This 2007 sedan was equipped with a manual transmission, JB4 software and an intake. This vehicle would be ideal for collecting testing data, we have found that the "Average" E9X owner has similar modifications.

Interested in purchasing our BRZ induction hose? Check out our product page for more information!
Thanks for returning for the second portion of this build! As mentioned in the previous post, our team was prepared to conduct extensive testing on this induction hose. Our main goal with testing was to determine the particular combination of components that would provide the most power output. Power output collection would be via our Dynojet. Each combination of components received an average output based on three consecutive runs all completed on the same day with essentially similar conditions. The variations of testing are below.
- Resonator and noise amplifier both installed
- Resonator plugged with noise amplifier installed
- Resonator attached with noise amplifier disabled
- Resonator and noise amplifier

The BRZ/FR-S is one of the hottest cars to hit the track in the past few years, and the Mishimoto engineers decided to do what they do best: cool it down. Naturally, we would be developing a performance aluminum radiator and silicone hose kit. Additionally we ended up with a killer direct-fit oil cooler kit, some very slick oil caps, and a low-temperature thermostat. As you may have seen in our other build-log, we are also developing a performance cold air intake, which we estimate will provide a nice increase in power and really bring out some of the engine tones being baffled by the factory system. This article is not about the full intake system we have planned. It's about the silicone induction hose we developed in the mix with all the products

We know you've been dying to know how we finish up creating a cold-air intake, and today is the day you can breathe a sigh of relief. We are finally at the last stage of R&D! After constructing a final prototype we were prepared to test fitment and ensure that power output and AFR readings remained unchanged. Check out our final prototype components!

Daily-driven test vehicle, 2013 FR-S
With all our prototypes ready to rock and our vehicle at hand, it was time for testing day. Our team set to work strapping the vehicle down to the dyno and prepared to make some baseline runs on the stock setup. Luckily, we caught a day where the weather was agreeable and the vehicle was free of snow and salt.

Interested in purchasing this E46 radiator? Check out our product page for more information!
Now that we have a prototype E46 radiator, what should we do with it? Test it of course! The data for this entire build is based around radiator testing. Check out the report from our lead engineer.
BMW E46 M3 Radiator Testing
Test Vehicle Modifications: Supercharged, intercooler, methanol injection, full exhaust. Professionally tuned @550 whp on pump gas.
Cooling System Upgrades: 13-row oil cooler for supercharger located behind the kidney grilles. Front-mount intercooler (FMIC) located in the front air dam. Upgraded clutch fan that spins faster than stock clutch fan.
Additional notes: 100% pure distilled water was used for all tests. Stock radiator was in good condition

How do you go about redesigning a radiator to make it perfect for track use? After coming to the realization that our existing E46 M3 aluminum radiator was not performing as we would like for track-specific vehicles, our team determined it was time to take action. Our original product was designed some time ago, and our processes, material use, and overall attention to detail have significantly improved since then.
These days Mishimoto is spending huge amounts of time in R&D to develop effective and efficient cooling
