I understand, I just slightly digressed, I think last nights Stella hadnt completely left my system.
Presumably the TDIs (turbo) suck in a lot more air than the V8s?
if I blip the throttle whilst standing next to the air intake with the bonnet open there is an induction noise as it sucks in but nothing too major at all (plus if its only just entering the bulkhead would the dash muffle the noise a bit?).
Also I know what your saying about smell in the cabin, when I stall/turn off my engine there is the smell of LPG coming from the air box, wouldnt want that in the cabin.
Finally your point on it not ending up looking very sleeper like, I appreciate what your saying and I think the trick would be knowing when to stop (thats why I had question marks with the light guards/chequer plate etc) The front bumper would look almost completely standard, the rear would be something like this:
Land Rover Discovery 1 300tdi HD Steel Rear Bumper - DA5647 | eBay which is almost identical to the factory one only the plastic corner caps have been made out of metal and are now part of the bumper. All the underbody protection would be painted matt black to match the underseal, And the hi lift (not that I own one) would be mounted horizontally onto the inside of the rear door (or somewhere else internally if it didnt fit), the winch would also be discreetly hidden.
TBH I dont go in water deep enough or travel on dusty roads enough to actually need a snorkel it was the 5 pints that suddenly made that random thought spring into my mind.
