Drilling a hole in the air filter canister for OBA

[alia176]

Dudes,

Are any of you getting the fresh air supply from the oem air filter round canister for your on board air compressor? If so, I'd like to hear about some elegant solutions. I know, I can simply drill a hole and stick my 3/8" hose and slather some sealant around it but I'm looking for a better solution. If you have pics that'd be great too.

Thanks.

Ali

I know nothing about OBA but if you want filtered air for the compressor wouldn't it be easier just put a fuel filter or some other small filter on the end of the hose?

I too would opt for a filter for the OBA as opposed to tapping into (modifying) the factory air cleaner housing. I don't have any really technical reason for this other than to keep the OBA installation simpler and modular as opposed to being integral to other systems...

By tapping into the oem filter housing, you're getting fresh, cool air for the air compressor. Otherwise, you're just compressing hot air from under the hood. Also, the oem canister helps with the "sucking" sound of the air comp.

This is assuming the vehicle is moving while you are running the compressor, right?

The air comp runs anytime as needed; vehicle moving or stationery.

To get filtered air, you'll have to go from the center of the cylinder, either straight underneath or straight on top. On top would look a little too cluttlered, so I'd look for an elbow joint or something you can thread into a drilled hole on the underside of the canister by the dust can.

This is assuming it will fit down there.

How big is the air inlet hose the compressor uses? Regardless, there's got to be an elbow fitting you can find somewhere that will work, the question is if it will fit under the canister.

It will only be cooler air if you have a snorkel.

I'll have to look into Ryan's idea - less clutter is nice. I'd like to make the hose as large as the inlet to the compressor, which is currently at 1/2" NPT.

seems like it would be easier and better to run the compressor hose up into the quarter panel (where the air filter gets its cold air) and then install an inline filter. You could go in at the antenna motor mounting hole. Try an outboard or lawnmower shop for a small air filter. One idea is one of those marine water/fuel separator filters for outboards that are the size of an oil filter and would mount easily on the fender or firewall. If you can find an air filter element to fit in one you would be goood to go.

alia i want a write up of that compressor set up when ur done. did u weld up a braket for it? then use a super cherger pully or whats the details??

If you're going to CM '05, you'll be able to see it in person

I didn't use the supercharger pulley because it'd cost more than the entire project put together

Shure am. Easy, just swap on an F aircleaner.

You could slather some JB weld pretty thick in one spot, drill and tap with pipe thread. Screw in a barbed fitting, and you're done. Would look clean from the outside.

For a "better" solution I would drill and tap a thick small square piece of steel and have it welded to the bottom of the air canister. Could epoxy it as well.

I like this solution A LOT. This way, a simple NPT plug can be used when the hose is removed for what ever reason. Thanks dude.
