So what would the downfall of mounting the airbox the way Ranger Shad did?

The large opening in the bottom would be less restrictive and the ease of changing filters etc would be great! BUT, does the system need restriction?

would attaching the airbox to the snorkel offer too much restriction?

would the open bottom have too much intake throat?

Just brainstorming. I am at the point in my install to make the choice of which way to go!

Dave

I dont know about the system needing restriction. I would
think as little restriction as possible is the goal. The only
problem I see with shads airfiter install is the filter getting
soaked from rainwater/snow. I don't know how much
water is forced into that vent when were driving. I have
mine pointed town with no issues and it supplies enough
air for the boosted version. Send him an email and see if
he has had any issues. I am sure he would have had
trouble by now if it was going to get wet. It does make
for a clean looking install. Also don't be afraid to
trim your bulkhead to make the intake hose fit. I fought
it the first time till I just got brave and trimmed away. I'll
never put a stock motor into my van again anyways.

Thanks Bill.
I just know from past experiences that some intake/exhaust systems like a little back preasure etc. But when I think about it, that was mostly with carb. model motors... an electronic fuel injection system should monitor and account for any of that!?!

I think if that airbox is slightly suspended, you shouldn't have a real problem with moisture. He has it pretty well isolated from the engine, and as far as moisture from the outside, I don't think you would get that much more than if you had the snorkel feeding the motor.

Do you have a 2wd or Syncro? how did you connect your snorkel? did you omit that plastic elbo in the bottom and connect the flex pip to it? or did you trim and morph the elbo down a bit and make the connection?

as far as the bulkhead, is that in reference to the airbox install? and which bulkhead are you talking about? the firewall, or the area above the wheel well/pocket behind the tail light?

and I agree, don't think I will ever have a van that I drive with a VW boxer in it again. Plenty of better options out there! I want miles of smiles... that means not looking down at guages ever 6 tenths of a mile! Wink

The factory snorkel has a drip point at the bottom so any moisture
can drip out. It's not huge hole so your probley right that much
doesnt get in there. My box is just drilled on the bottom
I left enough plastic to act as legs to keep a space below it.
I just had it shoved into the space behind the light. It stays well
and is easy to pull out and service. I do know that Brady did some
work on it when they had it in their shop last winter but I
think that was just to clean up where I uses duct tape on one
corner cause I didn't remove enough for the box to fit the first
time. I always meant to go back and weld it up but forgot.

I have a 2wd and started with a new crate motor. Went with the
HC oil pan from the start as I likes it's construction. I also have
the dual starter option for nothing more than the novelty of it.
I do notice the Honda starter turn the motor over faster.
The bulkhead I am talking about is the firewall just in front
of the engine that used to have the crappy plastic fuel
fitting bolted onto it that was known to fail. You will
route the big black intake hose from the throttle body over
to the airbox under it. I trimmed this panel up so it was easier
to run that hose under. Not really needed but I feel it also opens
things up a bit. Help get some of the heat out of there.
I think I have pictures of my set up before the turbo install. It's
all different now. Plus the fans on my drivers side for the intercooler
keep the engine cover temps down as a positive side effect.
I'll look for pictures.
Just remember if you ever have any questions that Jim and Brady
WANT you to call them. It not only helps them fine tune their
product but they have seen just about everything with the number
of installs on the books.

Dave,
Keep us posted on what you here back from Bostig or if you try out this airbox mounting strategy. It does seem to make a little more sense than the chopping and bending that Bostig recommends, but I also suspect they have their motives.
