So when the statement 'baffled sump' is used, it could actually be a stock sump that has had baffles welded into it?
Most usually are mate, althoigh the J's is bigger capacity than say the spoon one which is just stock with the baffles added.
You will find that you will be required to supply your old sump as a core exchange after you have recieved the new one, any decent fab shop should be able to put some baffles in for you
So am I right in thinking, on that pic, the drain plug is top left, the dipstick would touch down at bottom left and the hole in the baffle in the middle is to allow the oil pump to fit/operate?

Dry sumping is expensive, can be tricky to set up - but does release more power because the crank does not go through oil when it rotates. It also adds weight
Its not needed for road use, or even some competition use as long as the oil level is maintained.
My 348 has a dry sump. Must be for bar bragging then.
CC - yes to your comments.. the basic sump already has some kind of baffle around the pump..
I thought the bigger benefit of a dry system was that the car can be lowered further without the bottom of the engine hitting the ground - and the weight of the oil and sump could be placed closer to the centre of the car as ballast.
As far as I can remember all Ferraris are dry sumped. Its just the way Ferrari work, the engineering in their engines is simply superb. You can brag about the dry sump, the forged crank, pistons, the valve head shape, the cams ground from blanks & the list goes on.
Porsche also dry sump most of their cars. They have some tricky procedures for level checking (oil hot, engine running).
A dry sump does allow you to sit the engine lower down in the chassis - that can help the handling, a lot if you have a heavy engine block. You tend to fit the oil tank where you can though... dry sumping does add weight. The pumps are heavier because they do more work, you have the tank and the pipework. I took the dry sump kit off the Escort Rally car because its overkill & too damn heavy.
On the race cars we stopped using dry sumps, firstly because of the cost & secondly because they are a pain in the wotsits to set up properly - get the levels wrong or the scavenge rates out & you loose the engine....
