Clutch and Rear Diff Upgrade Experience - ZR-1 Net Registry Forums

secondchance · 09-02-2016

Saturday, leaving fair ground, it was about 95 degrees and bumper to bumper traffic pretty much all the way to I-81 intersection. With AC on full blast, hottest my car got was 213. For what it's worth, I have one 1/8" hole drilled on the thermostat flange. This thermostat mod dropped coolant temp by about 10 degrees at highway speed when I was running OEM radiator.
