Air intake help.
Hi everyone,
I was wondering if my 94 F250 factory turbo would benefit from the ram air set up like Dave has on his. It seems that the air is pulled in between the hood and top of the grill on mine. Has a K&N filter also.

The short answer is YES.
At 3300 RPM the engine uses 423 cubic feet of air a minute before you add the turbo boost requirements.
At the same RPM you are looking at somewhere between 700 and 800 CFM with 10 pounds of boost.
Now figure out how many square inches the stock snorkel over the battery is, and then picture 1,209,600 cubic inches of air trying to get through that hole every minute.
That is using 700 CFM as the base number.

Yepper, it makes a big difference. I just uploaded pictures of mine to my gallery. I have a a high flow factory replacement filter from AFE. It cost like $55. I used a dremel to cut away as much of the Radiator support as I thought I could get by with (conservative). Since the grill blocks the opening on our trucks, I drilled a series of 1/4" holes in the grill to allow more cool air(don't know how much that helped but I think it looks cool). Oh yeah the 4" tube from the air box is just a dryer tube cost about $7.
I have been thinking about removing the air box and installing a HUGE air filter and tube to do even better, but space is hard to come by under my hood.
