Righto - have been thinking about getting a scoop to try and cool things down at least a bit with the turbo. Spoke to FRP at Kippa Ring today, and he advised me away from the bonnet scoop - he does a fair bit of off roading, and has a sponsored comp truck also. He reckons he's seen a great deal more improvement from installing "gills" as per below. Essentially allows the heat the escape when not moving, but when driving, the force of air flow over the top of them actually "drags" the hot air out, removes the air pocket inside and lets more airflow through the grill also as a result (meaning cooler engine etc also). Sort of solves the whole 'mount a scoop forwards or backwards debate also - in the shot below, the fins face backwards, so don't "swallow" water as such on creek crossings, but allow air to actually flow past the vents as speed causing the dragging effect).

These were cheaper than the scoop so certainly didn't push me down a path of going something different to line his own pockets, which seems bloody good of him.

They are scheduled to go on Monday of next week, so I will update on the result post that. Fingers crossed!!!!
