The first pull was to 120 MPH coolant went up to 186 next pull was to 140 MPH 190 coolant temp. Now the last pull I had a good bit of room and did a pull to 160MPH . After all this my coolant temperature went up to 208 degrees and then came down quick to about 190. The recovery on this radiator is night and day compared to the CSF. Once I pulled over and for off the highway let the car sit for less than 5 minutes my coolant temperature went down to 177 .
I agree with you on this. To set the stage, I've never owned the CSF Radiator, therefore I can't make a comparison between the two. However, I too log my Z with Uprev, And I'm hard pressed to get Mishimoto coolant temps over 205 with many back-to-back 0-60 runs along with very spirited driving on remote roadways in my hometown. All this in 92 degree weather and still the water temp averages 201 and oil around 190-195. Mishimoto radiator performs very well. See my regression charts below, proof is in the pudding (as they say).

Having said that, anyone having temp issues with the Mishimoto or for that matter any radiator install, please read. MAKE SURE YOU PROPERLY FILL ANY NEW RADIATOR INSTALL BY RUNNING THE CAR WARM WITH THE HEAT BLOWING ON HIGH WHILE POURING ADDITIONAL COOLANT INTO THE ENGINE. DOING IT THIS WAY WILL REMOVE THE AIR BUBBLES WITHIN THE COOLANT. THEN AFTER 15 MINUTES TURN CAR OFF THEN BACK ON AFTER 10 MINUTES AND DO THE SAME UNTIL FANS COME ON. I HAVE READ MANY FORUM POSTS REGARDING TEMP RELATED ISSUES BECAUSE OF NOT PROPERLY FLUSHING THE COOLANT. Sorry for the bold caps, I just wanted to make sure forum members looking to replace their radiator see this important caveat.
