The steady, albeit slow, march of progress continues on the Impossible Evo X. The car is nearly ready for a baseline track experience, but as the car was optioned with the sensitive dual-clutch SST transmission, I must take all reasonable precautions to keep it alive. Today we’re doing it by dramatically increasing the car’s cooling capacity and thermal rejection ability!
Starting with engine cooling
First things first, I wanted to upgrade the radiator due to the Dodson transmission sump. Why? Because of the sump, the OEM radiator cooling circuit is not only tied into the engine but the transmission as well. This means the radiator has to reject more heat than it was originally designed for. There are plenty of great options, but one company stood out to me. Not only did they offer an upgraded radiator, but silicone hoses AND a trick oil cooler setup as well. I liked the idea of working with one company’s parts rather than piecemealing together a system, so I used contact of mine to put me in touch with Mishimoto. Did anyone else feel that? It’s the harsh glare of elites as they look down their noses upon me.
Yes, I’ve heard all the negative things about Mishimoto products in the past, but putting my hands on some of their more recent offerings and talking with a few competitors that use their products, I figured it was worth revisiting. In full transparency, Mishimoto provided me with a radiator, oil coolers, hoses, and coolant to give my honest review on MotoIQ.
