Mishimoto radiator track review

Hey everyone-

Since overheating seems to be a constant problem with the Focus ST on the track, I just wanted to give everyone a heads up on what I experienced the other day at High Plains Raceway with the new aluminum Mishimoto radiator installed.

My car is a 2016, completely stock engine (no intake, tune, intercooler, exhaust, etc). I have removed the AGS system and still use the stock shrouds, but that's about it. Morning temps were only in the 60's, with later temps approaching 80, so not really that hot with very low humidity (Colorado). I don't have any data logging, just keeping a keen eye on the temp gauge as the laps went on.

Basically, the car still got extremely hot, even with the new radiator and the heater on full blast. It took longer for the car to get to the 260-270 degree range, but still got there within 10min of hard driving. On a plus side while cooling down, the engine did drop it's temperature much quicker than the stock setup and the car never went into limp-mode. I'll most likely try an oil cooler next, along with maybe trying a session with and without the shroud.

I'm not sure if this radiator is worth the cost. On a completely stock car with low heat and humidity, I was seriously hoping for lower engine temperatures. Definitely feels like a letdown considering the cost of the radiator. The quest for cooler engine temps continues!

No change in the exterior look. If you didn't know it was there you'd never know it was there.
Do you have your grill shaved? This won't do as much without that opened us as instead of being blocked by the crash bar, it will be blocked by the solid part of the grill.

I have done all of this and more. It works great. I can hammer up a mountain pass and water and oil temps do not go past 200 now.
What were before temps?
