I have a keystone ram air hood (twin scoop) I have my air filter set up directly infront of my throtle body and a hole cut in the hood to provide air to the filter. My problem is rain, what would be the best method for providing air to the motor when it is raining? I have the 05 truck fans and I was thinking of plumbing something from the bottom. Any ideas?

 

i made a setup on my 04. i used 4" aluminum duct pipe and ran it from the opening in the front fascia to the bottom of the filter element. sorry kinda hard to explain. try to get pics. didn't notice any gains. no problem w/rain, just bugs & dirt. got to clean filter more often.

 

Stylin concepts sells a micro filter cover. It may help.

 

My friend has the same hood only the functional one and keystones answer to the water was to drill 2 holes at the back of the plumbing they built into the hood before it made a turn toward the stock intake location. I'll look for a pic for you.

this the hood???

I dont have a pic of the underside of the hood but about 3/4's up the underside the scoop stops and gets routed at an angle towards the stock airbox location. Where the scoop stops there are two holes drilled that supposedly the water will drain instead of getting fed into the intake. From the sound of how you have your hood cut other than the filter sock, or a shield to deflect the water which would make the ram air kind of pointless, I cant think of anything.

 

it would work really well. Make a scoop on the side where the air goes in behind the light. Then connect the tube to it with an enclosed cone!

the only thing is my filter sits in the scoops. I have set my air filter up like the ls1 cars

 

I think your best bet would to modify or steal the design from the cars and make your own box. Your talking about the SLP airbox or lid right? If you pick one of those up I'm sure you'll be able to modify it to fit your needs and avoid sucking in water.

 

On my sandrail I just have a K&N prefilter (nylon), this does a very good of keeping water out of the carburetors, but this is water being splashed up from the wheels and has time to dry before getting wet again.

 

I have to figure something out. My filter is a oval style K&N filter so I will have to build a box.
