2 row or 3 row Alum Radiator - advantages?

[tonysmach]

Looking for comments from the TB members on 2 row (1 1/8" dia) vs. 3 row (3/4" dia) aluminum radiators. Any advantages between the two? Does one cool better than the other? Is one better for drag racing while the other is better for the street? Or does it not really matter.

do you know what the wall thickness of the tubes are? All things being equal I believe the larger tubes should dissipate more heat.

Not sure of wall thickness. So you think larger tubes, 2 row, will keep engine cooler than 3 row with smaller tubes?

I replaced my 15 year old 3 row with the latest 2 row & the TR runs cooler.

Any other thoughts?

Larger tubes have better flat-to-tube ratio so they should cool better (more flat area of the tube that is in contact with the fins).
