Thanks guys... Brilliant inflow of information... :thumbsup: I guess I should make it 85 - 95 then. My radiator is small so I thought of using a remake one and try to get same area as the radiator for KR 42 (out of which the 7K came out). It is a twin row and i approximated it to count twice the area (I heard that it will not be doubled as the second row will not get same temperature difference as the first row). I cannot fit the same radiator as the KR 42 so I am fixing this. Hope I am doing right and anything to share, advice is welcome.. :paperbag:
KR 42 - 678 (w) X 452 (h) X 1 (rows) = 306,456 mm2
Project - 540 (w) X 360 (h) X 2 (rows) = 388,800 mm2
