Just got my custom radiators, all copper/brass for durability rather than lightness!! (and cost!)
Mockup:
2 core Charge Cooler Rad:
3 core Engine Coolant Rad:
The charge cooler rad fixes to the main rad with the fans bolted onto a mounting flange on the front of the main rad. The flaps that are on the main rad are also to fit the cowling to guide the flow from the front grill openings
Got some fibreglass arriving later so will make the cowling out of that
