more air

i just finally got my body lift installed the other day and while i was under the hood i was looking at the intake the PO had rigged up. it looks almost like a factory scoop from a gasser ran over on top of the battery and then part of the underside of the hood is cut away along with part of the bug shield. where would be a better place to pick up a ram a from? i know hypermax has the cowl kit but i dont think im up for cutting into the cab like that. are there any points that air is forced into the fenders i could run say a 4' pipe to?

thanks in advance,
keith

That scoop over the top of the battery was stock on the 93 - 94 trucks, not sure when it was first used stock.

Ram air from the grill area works well.

But you do have to unhook it when driving in snow.

Unless you live in an area where it never rains, the path from the ram air to the intake should be uphill to keep water out of the engine.

Is there a rule of thumb on an angle that will keep H2O out of the engine. I ask since I am looking at modifying mine in a few weeks...

I use a ram air duct from behind the grill,(cut open slightly), deflects air up behind the light, plastic cut out to a larger duct under the hood, works well, no rain or snow issues. Click my name, view gallery, "lots of suck no blow"

No rule of thumb, just logic on my part.

Water runs downhill and folows the path of least resistance.
However a pump is required to make it run uphill.

The reason I say this is it does not take much fluid inside a cylinder to hydrolock the engine since piston to head clearances are so close.
Cranking an engine over with fluid in the cylinder can damage pistons, rods, cranks or head bolts.

There is no need to add the possibility of engine damage from something that is so easy to prevent.

The only time a low intake opening would be bad would be while driving through water that was deeper then the scoop was high.

I have found a light powdery snow will go up the intake and cover the filter with a layer of ice, which will then choke the air off.
But I also plow snow, so I may be out there driving in a snow storm for a couple days at a time.
The blade also has a lot of the light powdery stuff blow over the top of the blade, so that may make it worse for me than most people will ever see unless they also plow snow.
