Well the water pump has sorted the cooling issue. I've removed the thermostat and made a big washer so that it doesn't leak. I had to turn the rd around to get the stock outlets where I needed. By the time the clocks read 50 deg the rad is hot. Winning! The pump is of the Davies Craig flavour and I highly recommend it to anyone looking to boost cooling potential at low rpm. I'll make a proper bracket for it shortly. here are some photos.
