  • Air Cleaner for TBI

    Basically, are there any compelling arguments for running an open air cleaner element vs. a closed one on a TBI set up?

    The winter temps where I live are what most of y'all (Washington & Idaho, & other parts North) call summer. I'm currently running an open element filter on my carb and have seen open elements used on a few TBI's in the area. My Scout is just old enough that it is not subject to smog checks and the accompanying visual inspection.

    Hood clearance is also a concern. My Scout has a 1 inch body lift and a 2 1/4 inch element just barely fits.

    I have only seen two scouts with FI and both had been installed by Bill. Did not see Bills with hood up but I think (pretty sure) the other one which belongs to a member of Bills same club was running one of those million mile washable filters (k&n?). Lots of those being sold for the other fuely engines, so I say go for it. In my part of the world I can't see one being of any benefit to me as 90 percent of or streets and roads are dirt. We almost need some form of aspirator setup on our farm vehicles it's so bad!! Good luck!!!

      I am installing a stock round air filter from a 1988 chevy truck on mine. It looks like I will have to notch a little bit by the water housing. It also points straight to the passenger fender where the washer bottle is, I will move the washer body forward and run a hose to the fender with a hole cut exactly where the washer bottle was.
      I'll take some pictures when I get there...

        Mark,

        Are you notching to clear the water housing or to make room for spark plug wires?

        I was looking at an air cleaner with an offset base to give me more room for the plug wires. I think it was originally designed for a Camaro with TBI to give disty clearance. My wires are currently kinda smushed (technical term) between the air cleaner base and the water housing.

        I'll be looking for the pics when you get yours set up.

        Binderman,

        10-4 on the aspirator. We've got some areas around here where the roads are too fine to call sand. We call the stuff "moon dust". A K&N with an outer or pre-filter works well with carbs. On my old sand rails we even added a few layers of stockings over the filters. Pretty bad when you have to ask the wife for old pantyhose to keep the dirt out of your engine. But, it worked. I just didn't know if the TBI system would be picky about the air cleaner, heat risers, etc...

          I use 3 different ones right now.

          10 in round, chrome
          stock TBI cut to clear and make open style.
          And the cone, cold air style sold on ebay for the chevy truck TBI. $37.

          All 3 work.
          depends on what you are looking for.

            snadracr,
            I have to get the TBI mounted on the adapter so I get an accurate measurement. It looks like it would have to be notched a little for thermostat housing right where the plug wires go. Another option for me and those that have a body lift is to use two or three air cleaner spacer that comes with the-TBI air cleaner, or make one? Shouldn't be long had some family medical issue's pop up this year, but that's life...

              Thanks y'all.

              I just wanted to make sure the TBI wasn't finicky about needing a closed system with heat tubes and such.

              Just found out I'm heading out on TDY soon so I'll have to put the FI project on hold. By the time I get back It'll be too hot to work on it unless I can convince the wife that we need to put a window a/c unit in the garage.

                One thing they are finicky about probably won't affect you is the throttle body likes to ice up on cold humid days. Thats why I (in Idaho) am using the heat riser and stock air cleaner.

                When I lived down there I had a swamp cooler in the shop...


                Whats TDY ?

                  I've have a swamp cooler in the shop for the last 2 years. I had to service it 2 to 3 times a season and it didn't do diddly during the hottest parts of the summer except spit out hard water droplets on everything within range. Darn near ruined my vise.

                  As I'm sure you recall, cold and humid is not a problem here. The only ice we see is in the freezer and the beer cooler. We did get a morning frost this winter; first time in the 6 years we've been back out here.

                    I had a small line from the water softener on the house to the shop swamp cooler.
                    It still got some buildup but you could hose it off...
