OK Gang! Put yer thinkin' caps on and step inside.

Any idea how to get that charge air pipe pointing straight ahead? My original plan was to unbolt the air inlet horn [nomenclature?] from the top of the grid heater and spin it 90 degrees, but noooooo... it's not a symmetrical bolt pattern! I cannot put a 90 on it and point it straight down either, because the throttle cable is in the way down below. Do they make an air inlet hown that points straight ahead? Does anyone have a better suggestion to offer up?



Here's another pic from the front with the doghouse cover closed, just to show how tight the space is we're dealing with:

*sigh* Would've been MUCH easier to do this with a non-intercooled engine.

looks to me like a cut and reweld with maybe a new flange base. do you have aluminum welding capability?



the big concern would be, if you face it forward, will you be able to access the 2 front bolts? or would you have to notch the inlet??

maybe you could aim it straight up and let the inlet flex tube take it to the front.



just a couple of ideas

I like the sound of that idea! I've been looking at rubber 90s to plumb parts of this anyways.



I guess I'll pull it back off and take it to a shop next week.

Now THIS is what I'm traying to accomplish! Sort of.

Anybody happen to know that part # for that horn?

From looking at the photo, how about a 1. 5" to 2" spacer between the inlet and the grid heater. This will raise the inlet high enough so you can rotate it 180º. It will then be pointing the the passenger side, now all you need to do, is to attach a 90º elbow to get it pointing to the front.



Just an idea, but it looks like it would work.

you might check with banks this is the horn for 89-90 non entercooled eng to add their intercooler #ad

It looks like you have 3918530. You can enlarge the holes with a file or bur the minimum amount to mount it sideways. I don't have the part number for one facing forward, sorry.

 

[Paychk]

A lot of the time the basic P/N is cast into the piece, have you looked closely at the forward facing inlet?

 

[dremelts]

If you have machine shop access maybe you could make a spacer about 3/4" thick that has counterbored holes to mount it to the manifold and then a set of tapped holes that would allow you to bolt the air inlet on at 90 deg.

Thinking outside the box....

What would prevent him from making this spacer out of strong/thick plastic?



Plastic/wood has been used for years as a spacer between carbs/intake manifolds.....

HEAT! The grid heaters on a cold day can stay on as long as 2 minutes.



IAT can be over 200* during the summer.



Wood will dry out and crack on the outside, and the inside will shed.



Plastic even if it does not melt will get deformed.



I would go with ceramic before wood or plastic. Best bet would to hit a machine shop to make a custom aluminum intake if you can not fine the right parts. Even 3" SS exhaust pipe welded on a custom 3/4" plate.

spacer

you might try "phenolic", it would be heat resistant, and is workable to your specs.

I made a carb spacer 1" thick, out of this material cause i did'nt want to spend the money for the aluminum one. this might be the ticket you are looking for.

Yeah, but that also equals a little extra soot out the tailpipe... . and a nice burnt wood smell to compliment the fragrant diesel exhaust! :-laf



Bah! Who needs grid heaters?! Darn, lousy intake restrictions... .

OK, then use mesquite. At least add a little flavor.

 

[Forrest Nearing]

a good hardwood should actually work well, but I'd just take it off, take it to a welding shop, and hand the guy a $20 and have him cut/rotate/weld it.

Well, pretty good suggestions everyone. But I took 83 crew cabs advice and decided to give Banks a call yesterday. Lo and behold, they were willing to sell that piece seperately from the rest of the kit! Price was $79-something. Doesn't sound much more than a similar Cummins part would've cost. Should be here sometime next week.



BTW, I'm going with a Ford Powerstroke intercooler in this thing(best fit dimension-wise out of anything I've seen so far).
