please help me find my bung
 

I've been searching for an aluminum bung to have welded onto my Greddy elbow in order to relocate the IAT sensor. I've searched Google, McMaster.com, boltdepot.com, this forum, etc but haven't come up with a source. It's M10 x 1.25.

Anyone got any ideas?

I'm aware that people have tapped the elbow but the machine shops I've taken it to won't touch it due to the thin aluminum.

You could drill and tap the hole yourself. Or, you could get an NPT bung, weld it on and then get a metric to NPT adapter.

lol at the title.....find my bung...hahaha

sorry, i know im no help :)

You could just run a hole straight thru and use a thru-threaded adapter.

Drill and tap is the easiest and cheapest way. Just do not over tighten it. It just needs to sit in there.

if you want a propwer looking bung Any machine shop worth a crap should be able to turn you up one and weld it on for a resonable price

I'm surprised something like this is so difficult to find... I'd be in the same situation if I wanted to have a bung welded onto my IC's outlet pipe.

Thanks for the suggestions guys.

Ok, so I'm a sissy. Once I got the courage to drill the elbow I realized that I had a good 3/16" of meat to work with. Practiced on some flat aluminum stock and then had no trouble tapping the elbow.

Drill and tap FTW!

That was going to be my post.... the elbow isn't thin by any stretch of the imagination. In some spots around the flange the casting if ~1/4" thick. When I was cutting the flange off, I was really surprised @ how thick it was. Had to bust out the ole 4.5" grinder with the cut0off wheel as the air-one wasn't "cutting" it. I would use some type of pipe-dope though.
