Ok, from what I can tell, the 911/996 radiators are 340x358x34mm --> 13.3x14.1x1.3" and the center radiator is 24x4.6x1.6". Anyone able to confirm these two? Again, just looking for rough estimates like 13x14x1 and 24x5x1.5...
PVX build has 2 radiators that are 9x16 x2-3? with fans and does well. He doesnt even have a center radiator and does ok without it, but the custom rad's are pricey.
The motorcycle radiators look too small to use and am now leaning towards mini cooper radiators - 10x10x1.6" along with a center radiator which would replicate the 996 for a fraction of the price with fans. They are literally like $90 w/fans or $50 without. They come in a thicker 3 core as well for cheap:
