Borne Off-Road Snorkel R&D Thread

[importfighter01]

@Mishimoto just curious.. if one wanted to purchase just the plumping, but not the snorkel, any chance of that happening? I've been toying with testing the idea of converting the factory fender vent into an actual intake point.

This would save me a lot of time on redneck engineering a bunch of pipe myself.

If you install these (https://www.americantrucks.com/air-...SB4teVygtJDd0ZKR-YgaAisyEALw_wcB&gclsrc=aw.ds)

and then create a fender airbox feed like this (https://www.ranger5g.com/forum/threads/fender-air-box-feed.11074/#post-212824)

then you accomplish the same thing and have access to more fresh air than the Mishimoto pipe in the inner fender since the inner fender can pull air from the opening at the front of the fender liner as well as via the Air Designs fender vent. Has worked well for me ?

I did the install over the weekend, overall I'm pleased! Considering the price and being an imported kit the fit and finish is good, quality of the parts is good too.

The difficulty of the install isn't too hard if you are mechanically inclined (Don't be scared go for it!). Just a heads up if you plan to rivet the mounting plate to the fender take EXTRA caution with the pop rivet gun (scratched my fender ) but luckily the snorkel hides it and my truck already has some marks here and there from different trails/outings (I mean without battle scars do you really offroad? ) This kit is well thought out and gives you everything you need to make the proper cuts. You'll need some basic hand tools, a 4" hole-saw bit, cordless power drill, and a mill file to clean up the cuts. The snorkel mimics the T5 Diesel look very well, Thanks Mishimoto.

Pros:
Looks great (Style points)
Fun noises from the intake epically under boost (Recirc valve sounds nice and the turbo spool)
MPGs shot up a bit (no rubber airbox plug installed/dual intakes)
Elevated intake level

Cons:
Whistling noise at highway speed (turn your radio up a tad)
Rivets for fender mounting plate wouldn't get tight enough, so I ended up using small low profile SS button head Allen bolts with lock nuts to secure mounting plate.

I was able to fix the heavy whistling noise.

The intake head has some weird cuts in it that go way higher than necessary where the band clamp attaches it to the downtube on the outside of the truck.

To fix the noise just insulate those holes and the noise is gone. I used some black vinyl tape, im sure some light silicone would work too.

Those weird cuts are rain drains. Blocking them may lead to water in the air box. Depending on which air box you are using, it may or may not be a concern.

Got my pre-filter today. If you plan to get one becareful with the rivets.....

Does the pre filter get pretty close to the roof line?
how much clearance is there?

Good to know. Whistling would drive me nuts. This is in my garage, waiting to be installed. Have you tried rotating the cap a little one way or the other to see if that affects whistling?

Thank you, good to know that's what their for! Luckily there's never rain in my area but 3x a year.
I am going to experiment with just blocking the front one with tape later and see if the whistling goes away if so I'll run it with 1 of the 4 openings blocked, the whistling is annoying!

The Whistling is from these "Rain drains" a member just mentioned rotating the head wont change it.

I wonder if the Beehive on that red truck whistles?

I didn't know if a slight alteration in the wind direction over the rain drains would make a difference.

Is that a Sy-Klone pre-filter?

In case anyone is following the whistling, I covered just the front water drain with some felt tape and road tested it quieted the noise to almost nothing.

If you are running the factory air box, it has a water drain at the bottom, so any water that might run down the snorkel will drain out of the air box. Taping the snorkel head rain drains shouldn't be a problem with the factory air box.

The Mishimoto CAI air box does not have a drain. On my previous build, I drilled a drain hole into the air box, then had a thumb screw I would install when I had a proper water crossing.

Just my $0.02, not recommending anyone do the same without due research.

Yes it is.

 

[Colo_Ranger]

Yes it is.

what's the purpose of that, over the one that came with the snorkel?
