Ever heard of ram air ect....

Has any one ever seen or heard of ram air or a cold air intake that really gets air from outside of the engine bay (not through the hole in the fender). I want to try something like this but I'm worried about water, slush, ect. that might make it through the filter.

I've seen the headlight removed, but I can't really do that because I drive it everyday, do they use filters when they do that?

I'm thinking maybe removing a fog light and rigging up something through a flat filter and maybe the stock airbox.

What do you think?

99 2500 dodge cummins, HTS auto trans, quadzilla/edge ez, edge stage 2 nozzles, HX40,special X pump, big line kit, custom dual filter intake, custom exhaust, holley blue, adjustable boost elbow, new intercooler boots, t/c lock up switch, suncoast t/c, leveling kit, new 285 bfg's, all the gauges.

I've wondered about removing the right battery and some how funneling some air from up front to the filter. Never acted on those thoughts yet.

I was thinking of moving the batter to the back side of the fender and moving the filter up where the battery was like on the duramax's then it draws the cooler air better??

From my studying of IAT temps...

Ok lets look at my BHAF setup...
http://mopar.mopar1973man.com/2002%2.../bhaf/bhaf.htm

Regardless of what ever I done to help cool the intake air it response the same. My IAT temps are always +40*F over outside temp. So if it 30*F outside my IAT temps will be 70*F at highway speeds.

Less boost the warmer the IAT temps become. This is because of less air flow the head temp effect the temp of the sensor. So in town my IAT temps could 40-80*F above outside temps.

Just something to consider for spending money on cold air systems...:shrug:

just run one battery. i took the passenger side battery off like 6 months ago. even on cold mornings (like high 20* without being plugged in) it starts fine (i have the optima yellow top battery), and i have all the extra room. im planing on putting the K&N right behind the headlight. should work good. another thing i thought about was getting a airbox and running one of the A/C vents into it (a ture cold air intake) but i havnt figerd out how it would work when you wanted heat:shrug: i might be doing some exparamenting with that idea not sure if its worth it though?

The only way your going to know if your setup works is to measure the offset of the IAT sensor temp compared to outside air temp.

When someone can reduce the IAT sensor temp below +40*F offset then I be listening... :

just don't put a tube from the airbox down to the bumper.... a guy in the truck club I used to be in from Nevada had this, in Havasu he went through a decent mud puddle and hydrolocked his engine....

I wasn't there as 2 hours before this my trans blew up... but saw the video.

Oh, trans blew cause I had gotten a transmission flush 2 days prior, not cause of what I was doing... 45mph on pavement.....

A tube from the cowling to the air box is much safer...

Uhm.......... Your almost sounding like it can't be done. I'm kind of taking that as a challenge.

The only reason I say it can't be done is watching IAT sensor temps from start up. The IAT sensor matches coolant temp which matches outside temp.

So as the coolant warm it tend to warm the manifold and increase the manifold temps too. So the IAT follows coolant temp a bit too. So no matter how cold it seem to get out here the IAT always seems to follow the +40*F rule... But with winter fronts in its a +50*F rule now...

So basically the outside temp is 20*F and then IAT temp would be 70*F... Which isn't bad...
