Cooling issue on highway
Just got my new build back on the road. 6.4 swap into a dart. Breakdown is 3 row aluminum radiator. Custom fan shroud with pass throughs installed on all four corners. 180 stat. Holley efi turns on the fan at 190 and off at 185. Spall 16” single fan. Cruising around town 35mpr under it cools down within a matter of seconds. Sitting at a light cools down within seconds. Get on the freeway car will jump up to 195 and stay there.. fan is on at this point till 185 but it won’t go down from 193/195. I’ve read that the fan will cause a blockage at certain speeds.. so I did the pass throughs.. didn’t change it. Not sure what way to go next. Manually turn off the fan via switch on the freeway or make an air dam on the bottom to scoot up air? Fan blades are about 3/4 away from radiator core. Thoughts? Thanks
