Water in intake tract.

[gmustangt]

On the Pro Rmk, the OEM plastic airbox has a drain in the bottom , as well highs and lows to prevent water from entering the motor.

On the turbos thats gone.

I find the oem intake vents aren't 100% water tight , and water makes it way in there. Engine heat rising and melting the snow.

Running an additional Fire & Ice intake which sits horizontal and does not help water intrusion , IMO.

What are people doing to prevent water from getting through the stock intakes and in the motor?

Shouldn't an "air compressor" have a water drain on it??

lol yes , but does your airline have a drain on it...

 

[mountainhorse]

Nope... just the tank...

Just pulled a intake off a sled in hood deep powder today- and sitting in the shop there was the "scary" puddles of water sitting in the intake track.... Might just make a drain with a flapper, at least I can create a lower containtment point for the H2O and "pinch" the flapper to exit any residual ..

I think most people would be surprised how much water can get in there.
Maybe they all do it and the motors are fine with it.

Your going to put a drain on the positive pressure side?

I agree. I think this is a problem as well. I've put a lot of thought into it, just haven't come up with a great solution yet

Perfect solution would be a custom formed bellmouth "snorkeled" in to the hood plenum with a prefilter on it.

Other than the bellmouth part I feel like that could be doable. Possibly a perforated 6"-8" tube section with prefilter over it might be more easily doable.

It will be located on the C/F lowest poin

If there is that much water sitting in your intake track that's means lots made it into your motor. Doesn't that worry you? Maybe it's a non issue? All I can envision is that snow/water washing the oil film off the intake side of the piston/cylinder.

Considering it will pool at the lowest point , my concern is bottem end bearings.

There's gotta be snow dust making it in in some cases as well.

I made up this prototype intake with some scrap mild steel pieces I had laying around the shop. You get the idea. I had been kicking around the idea of doing this for awhile & this thread finally made me do it. We'll see how it works. If it works good I'll make a "pretty" version out of aluminum.

 

[gmustangt]

Is that 3" , does it fit?

I dont recall there being much room in there.

Yes to both questions

But I also have the SLP intake in the top, that probably helps a little

There have been a multitude of smart people that have felt the premature ring wear we have been seeing in the 2011 and later CFI-2's is due to water intrusion from the stock airbox...

 

[gmustangt]

Going to double side tape the perimeter of all the intakes, hopefully close all the little gaps and keep 95% of it out.

Free water injection, extra power all day

I had to seal the entire mating lip from Sliber turbo carbon fiber intake to eliminate any more water from coming into the air intake - also low point drain should help.
I don't think condensation is where it is coming from- as others we have pulled off are dry as a bone.
