I'm strictly aircooled but I'm currently working with a low budget drag Bug club project using 1.9 wbx heads with the water jacket sealed. The heads are fitted to 1914cc Type1 barrels with Type1 studs to a modified wbx crankcase. Each head is to be cooled with a rad' and fan from a 1.0l Polo. We've mounted the rads side by side in the rear window opening. Air is ducted from the rear side window openings to the fans which blow up and through the rads. We are yet to source a pair of electric in-line water pumps which will hopefully initiate a flow through the head, up to the top of a rad' and out down back to the pump. Once the head tries to boil the coolant, fingers crossed a thermal syphon effect will accelerate the flow of the coolant, the pumps become redundant and the heat gets transfered. It's very experimental and we're hoping to be the first to keep the coolant in the system (and the core plugs in the heads). Pics still outlawed
Watch it steam down the 1/4 at Big Bang if it's ready
