For it's size
this is the lightest radiator we've built, coming in well under a kg.
The core is a single row 29mm thick.
The top tank is shaped for minimum water
capacity, but maximum even dispersion across the core. That's the reason
for the peak in the tank - like our Hot Chilli intercooler tanks.
The 16" fan turned out to be overkill & weights
far more than the radiator.
This is the water inlet/outlet block we made
for belt clearance.
