Actually, Steve,  I do have a bit = less area=20 for the core inlets.  I decreased the inlet area =  from my=20 original 48 sq inches total for the two coolant cores to 28 sq inches = for an=20 approx 40% decrease in area.  That worked OK but at WOT the temps = would=20 approach 200F, so I plan on opening it back up to around 38 sq=20 inches.

Ed,
