2nd Gen Non-Engine/Transmission Functional hood scoop for diesel

[jmateer]

I have a 1997 W3500 Dodge Ram Duallie. I have been thinking about adding a functional hood scoop that feeds cold air directly to the top of the VOLANT air box. My questions are;

1) Has anyone done anything like this already?

2) What happens when it is raining/snowing and you are forcing water into the air box?

3) Does anyone know of a company that makes hoods with functional scoops & duct work for a diesel?



I have been searching the internet and am coming up empty with anyone that has done this with a diesel engine.



Thanks in advance for all that may offer their expertise.

came across this site while looking around. At the bottom of the page they say they have scoop hoods in developement for 1994-2001 Rams. May be worth a call.



Dodge Ram Air Hoods * Dodge Cowl Hoods * Dodge Fiberglass Hoods * Moore Fiberglass Hoods and Performance Products



Hope this helps

I have a Reverse Cowl Hood, it takes air off the windshield. Sure rain gets in but for seven years no problems. Had same hood on my 96 V10

Hello Monkeyman: How well does the reverse cowl work? The engine still has to suck the air in unlike a front mounted scoop where the air is being forced into the air box. I would think at speed there would be a great deal more air available with front scoop.



Thanks for your reply.



P. S. I am surprised that more people are not thinking of this or have done it.

I have not done this YET! I had the same concerns as you (rain /snow) I was going to take one of the non-working add on hood scoops and make it work so the air will come in and go to the air box with some home made ducting.

The cowl area at the bottom of the windshield is a high pressure area at speed. Same principle why the air box mods work so well with the hole cut into the cowl area of the firewall with a tube ducted into the airbox. No reason you couldn't do this to an aftermarket box as well.

OK, so it looks like a cowl induction system will work just as well as a scoop. Since I am trying to get my head around this... What about my original question about water/ snow melt etc getting sucked / blown into the air box and possibly into the intake? Would this not cause some serious issues? How do you get around this? Do you use something as simple as drain holes in the bottom of the airbox?



Thanks

If you had a air cleaner like the good old days in the middle, a front scoop would work great. Like above the air gets sucked and pushed in close to your air intake. I have a Scotty ll which uses hole in fire wall to capture air off winshield. Plus hood scoops are pretty much worthless at low speed! I also do not get insects etc inside my engine compartment.
