PERFORMANCE HEAT EXCHANGER, FITS TOYOTA GR SUPRA 3.0L, 2020+

The GR Supra is a showoff. This is not news. No one is going out to buy one of Toyota's most revered sports cars because they're looking for something sensible. Nope, they're looking for a shouty straight-six, all wrapped in a sleek, low-riding 2-seater body. They're likely looking to turn the A90 into their next mod-machine as well. If you've been following our R&D, you'll already know that our new heat exchanger design, on paper, is also quite the showoff. If you don't already know that aspect, make sure to head back to our last post, which outlines the new design features.

What we want to know now is, sure, our heat exchanger can talk the talk, but can it walk the walk? To find out, we arranged a torture test that allows us to record the air-to-water intercooler system's performance under the harshest conditions.

Our heat soak test is performed on our Dyna Pack system. The test consists of a series of 6 consecutive power-pulls

It's hard not to be a showoff behind the wheel of the A90 Supra, and we can't exactly blame you either. The car begs to be thrashed, and resisting the exhaust pops is futile. The namesake is one that demands attention (ISSAT A SUPRA?!), all wrapped up in a sleek, not exactly subtle body design. The fact is, the Supra is showy, and that's fine. We're just as eager to be just as showy with our new means of reducing the intercooler temperatures in the form of a performance heat exchanger. So, rather than getting existential about the Supra, let's just dive right in. Without further adieu (drumroll please), we'll let some of these photos speak for themselves.

The first and most apparent revision is full aluminum construction aimed at exponentially improving the durability of this heat exchanger. Focusing in on the core, we expanded the thickness of the core by 10mm, for an overall 42mm thick, single row core, equating in a 31% increase

The tag-team between BMW and Toyota that resurrected the Supra was a good sign that this platform would be well prepared to take on any challenge that the road had to offer. That is, in stock form, at least. We all know that the Supra is a tuner's dream, so plenty will inevitably see some means of increased power by way of a tune, turbo, or a combination of the two, where the stock heat exchanger just won't cut it. Luckily, our engineer, Jason, has already been on the case and has a plan for keeping the intercooler's coolant temperatures in check.

We start with the core since it does the heavy lifting. When it comes to any variation of a heat exchanger, bigger is typically better. At least the right amount of bigger is better. Optimizing the cooling capacity of a heat exchanger core means not making it too big; otherwise, efficiency is lost, and it becomes more of an obstruction to any other cooling components behind it.

Nothing shows progression in technology quite like integration. The means of creating one item that performs the function of four is the way of the future. Just take your mobile phone that you're likely reading this on. Fifteen years ago, it was just a phone designed for talking and texting, with some limited internet access, and now it's a computer in your pocket. Similarly, the intercooler inside of the B58's intake manifold is a pure form of integration in the name of performance. The marriage of these two components, though, means that the intercooler's heat exchanger is now the key to performance gains for the A90 Supra, and we here at Mishimoto are on the case.

Air-to-water isn't exactly brand new when it comes to intercooling. This method of exchanging charged air temperatures
