Hey Guys!
We’re back with some exciting new stuff to keep your FK8 running cool. This time it’s our secondary race radiator kit to give the CTR’s cooling system the help it needs!
“But wait, why not just design a new radiator?” A good question and one I’d expect you guys to ask. Radiators are in fact our expertise. The K20C1 with its front mounted turbo setup sits pretty far up in the engine bay and squeezes together the cooling stack, which ultimately limits the room we would have to improve on the heat exchanger. Even if we played with fin densities and bumped out the thickness of the core, we would expect cooling results similar to those from the stock system. With that, we decided to get creative.
I’ve mentioned plenty of times before the lengths that Honda went to with the aerodynamics. We’re looking to use that to our advantage with this additional radiator. Since the driver-side brake duct was already occupied by our oil cooler, we had to look elsewhere for a mounting location. That hood scoop isn’t there just for looks. It works in conjunction with the undertray to pull air behind the engine and out under the car, both in the name of aerodynamics and to help pull heat from the engine bay.
Knowing this, our engineer, Dan, mounted one of our small radiators directly in the path of this airflow to pull even more heat from the already overworked cooling system. Given the extra heat exchanger’s location, we tapped into the heater core’s return line. This way, some extra heat can be pulled off the coolant stream without sacrificing creature comforts like keeping you warm in the winter. Our road testing indicated that there’s a positive effect from installing this kit, but we wanted intensify the testing circumstances and couldn’t mimic real world aerodynamic conditions when we tried on the dyno. Getting a full test has been tricky.
@JLOracing and his team at USR have been a huge help and have in the past used some of their track time to thrash about in the deep south’s heat while equipped with our products. However, with their engine undergoing an overhaul and the weather getting a little too brisk for proper testing, we’ve missed that opportunity this season. Regardless, we want to share what we’ve had up our sleeve for the last few months, since this project has experienced some new developments and is moving right along.
As always, feel free to shoot me any questions, comments, or concerns you might have!
