Nick here from Mishimoto! I just wanted to kick this thread off to let you know we've been working on a performance radiator for the C7 platform! If you're unfamiliar with our brand, we are a performance company based in Delaware, and focused on keeping things cool, and spent some time last year beefing up the cooling system on the C6 Corvettes
Our presale is quickly approaching, so we wanted to make sure that we caught you guys up on what's been going on here at the Mishimoto R&D facility. So, in the weeks leading up, you'll be getting the condensed version of our development process starting with the review of the stock radiator system.
The C6 might have gone out with an LS9-powered bang, but the C7 came in with a thunderous boom. Corvettes, no matter the generation, all seem to have their own timeless look, slightly updating the visuals from each iteration. The C7, however, molted its skin and entered into the market with a much more futuristic look. The current gen is still round where it counts, which includes the track-focused aerodynamics built into the body with enough pronounced body lines to give this American Muscle hero an Italian supercar look. And we haven’t even got to the Z06 yet.
Looks aren’t the only aspect of this Corvette that carried the C7 into the 21st century. Chevrolet introduced the LT series, their newest line of small block V8s, under the hood. The new heart of this metal creature features direct injection, coupled with high-compression for an efficiency-packed 6.2L producing 455 hp and 460 tq. The mighty roar this thing releases is even louder when combined with the 1.7L Eaton supercharger strapped to the intake manifold in the track-focused Z06. With the LT4 taking the place of the once monstrous 7.0L LS7, this Z06 is even more savage than before—almost too much for most to handle.
I'm sure you guys are already privy to the fact that these Corvettes, even in their 'track-focused' modes couldn't stand up to the heat that the LT1 and LT4 produced in some cases. It's no wonder since the stock radiators measured in at barely an inch thick, with only another fraction of an inch when it came to the screaming supercharged Z06. Unlike the C6, the C7's cooling system isn't pulling double, or triple duty by cooling the oil or transmission, but even still the coolant still can get to dangerous levels with this stock unit.
Luckily, we're already on the case, and our engineering team has a plan for the C7's new design which I'll be dropping here next week! Make sure to head to our Engineering Blog for the full review on the stock system!
Feel free to shoot over any questions you might have!
Part two of our performance radiator development coming at you! For the full look at our plans for the C7's radiator design, make sure you head over to our Engineering Blog!
Our design process starts with our engineer makings some models with the help of our Faro Design Scan Arm. He'll make a digital model of not only the stock components, but also the general area to keep reference of how much space we actually have to expand into.
From there, we're able to create a physical manifestation of the digital design by way of our array of 3D printers and the steady hand of our in-house fabricator. With the skeleton of our design fabricated up, we now have a 1:1 scale model of the design to ensure proper fitment before we even start the manufacturing process.
For a look at the full fitment prototype, and a glimpse at the final product, make sure you head over to our Engineering Blog.
Here it is in the flesh...well, metal, our Performance radiator for the C7 Z06 and Stingrays:
This new take on the C7's cooling system is sporting a 2", 2-row core with a more efficient fin design that should give the Corvette the temperature reduction that it so desperately needs on the track, and the street in some cases. The core might be the star of the show, but there is a fully loaded supporting cast that also helps with this radiator's performance. For instance, in order to squeeze more rows into the core design while fitting into the limited space that is the nose of the Corvette, we flipped our header plate. This allowed for even more core volume, plus just giving a sleek look to the radiator.
For more info on our radiator's design, make sure that you head over to our Engineering Blog! Keep you eyes peeled since we'll have our info on how this radiator performs, along with a discounted presale coming at the end of the week
As always, feel free to shoot any comments, questions, or concerns my way!
It's the end of the week, and as promised, I have the final piece to our C7 radiator development hot of the presses for you! As always, makes sure that you head over to the Engineering Blog to get the full scoop
This time around, it's the Z06's turn to sing, and that LT4 has some serious pipes! For our testing we wanted to simulate both street and track driving, so we performed two different tests in order to encompass these driving conditions. Our first round of testing was a steady-state load test. For this test our engineer let the 'Vette get up to operating temperature, then held the vehicle at 4000 RPM for 30 seconds. The load test simulates heavy long term driving as well as comparing the efficiency of our radiator over the stock unit under steady load and heavy stress. Our second test was designed to simulate varying engine speeds with our heat soak test. To complete this stage of testing, our donor Z06 was put through 4 back to back runs at different engine speeds to show how effective our radiator is at dissipating heat with the water pump running at varying pressures.
For a look at how well our radiator performed over the stock unit, make sure to head on over to our Engineering Blog for our testing results!
Also, this radiator is now available on presale, along with fresh new silicone hoses. Make sure to get in on the special Presale pricing before it's gone!
