Feroza has too much intake pipe-work!!!!

Cheers JD,
This is supposed to be just a "town" 4by with a bit of an option for a jaunt here and there. No room for a fridge (unless I fold up one of the rear seats). I have an old (original type) ARB compressor sitting in the shed and would like to mount it somewhere. The bloody thing has 220,000klm on it so it's well outa warranty!! haha
Anyway, I just hate to see wasted space under the bonnet.
Cheers

The ducting does serve a purpose. It forms a "column" of air in the intake that allows for more inertia of the air to fill the cylinders at low revs. If you remove it you will remove a lot of the low end torque of the engine.

The principle is not dissimilar to blowing across the top of a small and a large bottle, the larger one not only makes more noise but is of a lower pitch. The lower that resonant frequency is of the inlet manifold, the better the torque of the engine will be at low revs, but at the marginal expense of the top end power number (not really relevant to 4WDs anyway, and only by a couple of percent usually).

Same principles apply to the exhaust, that's why really big, short exhausts don't always give an improvement in drivability over a stock or slightly above stock size in urban driving. Lengthening the exhaust runners increases the low speed scavanging (emptying) of the cylinders(the "reverse" of what is happening in the inlet manifold), this being the principle behind extractors as compared with the cast iron OE exhaust manifold.

Thanks Gary, interesting stuff.

Your a sick puppy Barb Hahahahaha
Hi how ya going, havent caught up for a while, looking forward to a couple drinks when we hit KI
