Hey guys, really can appreciate the tips.

I got a 2005 with the Vortech S/C. The air intake/filter is in behind the driver side bumper/in front of front tire inner fender liner.

This is my only car, and I've driven in the rain in the past, but been experiencing some hurricane weather.

I don't have the stock plastic underpanel, it wasn't with the car when I bought it. I am looking to get one of these, do you guys thing that will make a big impact?

Any other suggestions, tips, or anything, would really appreciate the help.

Get rid of the intake that goes down there and get a filter that goes on the blower in rainy weather.... Problem solved

 

I did mine out the front, for the very same reason.

pic 1 is with stock Vortech Intercooler.

pic 2 is with Large Intercooler.

 

i ran mine behind the front tire for 2 years with zero issue. your misfire is coincidential, as any meth kit will spray WAYYY more water thru your system than anything that could possibly make its way thru your HOTT blower, intercooler, and all the cold piping. Its just not possible.

 

Ya, the amount of moisture that will come through that oil based filter is almost none. Chances are rain is getting into an electrical connection somewhere causing a misfire. I would check the passenger side where the main harness enters the car. It's notorious for letting water in and it gets down into the ecu.

 

mushroom style filter kit in the engine compartment. problem cloved.

 

It's not the water. People use 1000cc water injection systems with no trouble. There is probably more moisture in that fuel just from sitting in the tanks than comes through an oil based filter.

 

when your spraying meth its being injected post maf. water coming through the cone goes over the maf and wigs it out. i had this issue in really rainy conditions with my twins aswell with the location they sat in with the gtm kit

 

But you are trying to imagine the small amount of water vapor pushing past a hydrophobic filter media soaked in a hydrophobic substance (oil). It just won't happen. I've driven with my air filter 2" off the ground for 3 years now through rain and snow with not a single issue. On top of that thousands of drag cars spray water pre-turbo as well as quite a few aircraft which is well before the maf. Raj even tested it on his car with no issues.

I'm telling you, it's not water through the filter. It's probably the same thing that happened with my old honda. Every time it rained water would get into the harness somewhere and short something out causing a misfire. If water vapor got through an oil filter then that would cause problems on every single ram air hood vehicle on the market and that's just not the case.

 

no it was definetly the water, none of my harness was exposed and the car was only a year old so i doubht it was a corroded connector that only presented itself in the rain. also when i would get home and pull the maf out it was visually wet and i would have to blow it out with maf cleaner and let it sit for a little before i put it back in.

 

Water condensation on your MAF was not from the filter. As coincidental as it may have been its not possible.

In high humidity, water in the air will condense. it is not rain coming thru the filter, past SUPER hot turbos or superchargers.

 

can only tell you what has happened and i doubt its humid in 30-40 degree temps when its raining. in his case maybe its not the same issue but on mine im convinced it was the rain. only happened in the rain and there was never any moisture in there any other time i checked the maf

 

The colder the air the more likely water is to condense. That's why dew forms as temperatures drop at night.

Along with that when it's raining that means the air is fully saturated aka 100% humidity. Your maf and intake piping was acting just like a pop can in humid weather allowing condensation to form.

Maf wires are extremely hot when the car is running so it should cause any water to hit it to evaporate anyways. Again to my example of the millions of cars on the market with factory ram air systems that go straight into the maf.

 

it would only stumble when boosting in the rain if i stayed in vaccum no issues, i checked this a couple time because i was curious, pulled the maf after some driving in vaccum and was dry as could be inside. boosted after the filter had already gotten wet in the rain and it would instantly stumble and run like dick until i parked and pulled the maf and dried it

 

Sure it wasn't the reduced airflow from a saturated filter? It would restrict flow if it is completely saturated in water.

It just doesn't seem like water should be getting through a hydrophobic filter media. Every trans am and camaro with ram air would have problems if that was the case because the maf is only about 10" after the filter directly open to the front of the vehicle.

 

could have been but it doesnt explain the water, my filters were xposed right above the ground in front of the front tires with no fender liners

 

Weird, mine is exactly 2" off the ground under the car (midmount turbo) and I drove it daily for 3 years that way through rain and snow with no issues. I'm not saying water wouldn't cause the misfire but it just seems odd to me that 10's of thousands of ram air intakes (oem) never have rain issues.

 

I think it could have to do with the filter being placed in front of the tire so the water is getting thrown on it and I had the jp type n bumper so the filter was exposed via the opening in the bumper from the front aswell. Think it was just getting to saturated

 

Ah, tire flinging water would probably provide a lot of water. You need to saturate that bioch in some oil then to repel the water! Water beads off of mine like a baby seal

 

I would have it I kept it, I got rid of it after loosing a headgasket and having some other issues. Got a zr1 now >
