Good range of ideas.

General thoughts are increase air flow by putting more in, bonnet open, ducting etc and getting more put, side vents, bonnet gutter etc. Tj101 had success lower temperatures jist by removing the bonnet drip line on a car.

Improving air exiting at the rear of the engine bay seems a good way forward.

Can anyone find those Empire mesh puma rear bulge grills? I can't dind them now. Cheers
