3inch plenums
Found these 3inch plenums on a 7.3L in the junkyard.
Any benefit to using 3 inchers when I build my intercooler setup?
Sorry for the big pictures, not sure how to make them smaller....

I don't know much but if you use them you have to get a bigger turbo. Our inlets are 2 1/2 inch or maybe its there 2 3/8's. They went to 3" in the SD but I've 'heard' that the SD turbo's aren't as good? They don't have anything to do with the intercooler.

I put 3 on mine. Not a good idea with the stock charger. Im trying to figure out how to make the outlet for the turbo and an intake y that isn't gonna hit each other. At the moment I mod the stock y pipe to work with them.

Glenn, you take an OBS wheel and shove it into the SD turbo. All good then with no lag. They sell that as a Wicked Wheel.

Grabbed those 3 inch plenums from the yard today. Gonna build my own intake Y for a intercooler setup.
Got an intake Y (intercooled style) off a larger international that had the 3inch plenums, the only problem is the inlet of the Y comes in from the top, not the side like we need. So I'm gonna try to cut it off and Tig a 90 on it.
This will probably be a PITA, so I'll just try it from 3 inch exhaust tubing.
I'll get Pics tomorrow.

Now, I'm not planning on using this aluminum intake, but it shows what came off the engine from the yard.
What is the SIZE of the turbo outlet? I'm looking for a V-band piece I can weld onto, to start the intercooler. Is it 2 3/8" or 2.5 inch?
