Done some mods today to help with cooling.

First image is the coolant pipe that runs right under the air filter housing, that prewarms the air before it goes to the throttle body. I've wrapped it in exhaust wrap to reduce the temp. Also which can't really be seen in the image is I've replaced the throttle body gasket with one that reduces heat transfer from the intake manifold. The old one was some form of aluminium material that had a checkered texture which was flaking away, so the throttle biddy got a good clean.

This shows a piece of thick neoprene that aive put either side of the radiator from inside the cowl, to help channel more air through the radiator.

This last image isn't really a cooling mod, but I've lined the inner of the bonnet where it meets the bonnet rapes to reduce rubbing if the paint. It nicely seals the bonnet at the front and back so I don't mind getting a hose on it without fear of flodding the engine bay.
