2002 3500 Cold Air Intake, Cheap And It Works
 

Bought a used box, modified it with a 4" alu pipe conection, piped it to front. In front have a trimmed 4 x 8 funnel, so it fits next to intercooler.
Batteries is side box under bed
will see if i can up the rest of the pic's

here are the rest.

ok first question why? you turbo does all the sucking of air if you start to force it it it will become turbulent and will eventually result in a loss of fuel milage, it happened on my budies truck, basically it will be working against itself. the tubine pulls in air then with that that will be forcing air against the turbine blades causing them to intern slow down

some dyno results ive seen beg to differ

i can see what 94cummins is taking about..

on a dyno your not forcing the air in. your just giving the intake easy access to fresher/cooler air.

also all the tubing is corrugated it's a bit restrictive... probably no enough to make any substantial difference

I been toying with the idea of moving the batteries to the tool box in the bed to make more workin room under the hood and moving the air intake up to the front of the truck so the air comes in right off the front of the truck and is basically a straight shot into the turbo area.

Look at the some of the drag racers and pullers, they take the headlight out and stick the filter up there to helping forceing air up there cant be all bad.

they have way larger turbos taking in way more air the out little hx35's hy35 h1c's etc..
alot of those rig are race only.

I'm talking about the Duramax trucks. I know allot around here that run like that on stock chargers.

i bought one of these thought i would mount it over the top of the intake.

but now i'm having second thoughts

Have been looking at pic's of all the fancy cool air boxes, ice boxes, where there is a shield between turbo and air filter, come on guy's what is wrong with fresh cool air available for engine??? Know it is not that pretty, since I am the only one looking under the hood, no big deal.
Was not intenden to ram it in, since i usualy don't go faster than 80 mph.

i think this is a great idea, he is not necessarily forcing the air in, but more-so giving it a much cooler intake air temp, witch infact could in the long run, lower egt's and produce better fuel mileage.

I would disagree with the forcing of air arguement. IF that was the case, my Scotty II wouldn't drop my EGT's by over 150F... (It gets "forced" air from the cowl.) Truth is with the paper element filter still in there, you won't be over-feeding the turbo. I bet you still would see -5" H2O draw on the filter at highway speed.

If you are concerned about turbulence, get a TAGIII....

I agree completely. With any filter being between the ram air, and the turbo intake air, it's going to straighten out before the turbo. If this works exceptionally well, you could also ditch the "high performance" air filter (k&n, amsoil, and such) and go back to a stocker, that way the ram air will be sitting in the air box waiting on being sucked through by the turbo.

Seems like an excellent idea!!
Good Job. :U:

I don't think he's trying to make a ram air, it looks more like he is just making the location it draws the air from further away from the heat of the engine

My thinking is, getting cold fresh air from the front, before it is heated by engine and turbo, was not trying to make it ram-forced, just air available for turbo without creating a vacuum in air box.
Remember turbo creates a lot more pressure, than ram air will ever do at 80 mph.

u dont get better milage from cold air to an extent as u do with hot air, cold air molocules are small and tight hot air molocules are big , heating your air youll loose perfore but burn more fuel cooling it youll gain performance and burn less of the fuel in the cylinder
