I am looking to buy a new aluminium radiator this spring. I looked at the champion radiators and they have some options. I'm looking at: 2 row 1" tubes 3 row 4 row I have a 2300cfm electric fan with the standard 22" radiator and a shroud I set it so that it keeps it around 180 degrees. Driving and getting airflow is not a problem at all but in the hot summer in traffic, the temp creeps up more than I'd like. Now I'm wondering which of the radiator options allow my fan to pull more air through and which setup would be best to keep it cooler at idle. I have read a lot of articles which would say that 4 row makes it run hotter cause it's more restrictive and 2 row with 1"tubes has the best efficiency. What about 3 row? Which radiator would be the best option? I have a 360cui with some unknown upgrades but it doesn't seem to be close to 300hp.
