Like he said its an easy upgrade if you have some welding skills. I used 1/4 in plate, 3in exaust tubing, and a stock gasket and its held over 60 lbs. If I remember right you can make it out of 4in wide strap, and just grind out the area where the valecovers sit, and use your stock intake as a pattern for the bolt holes. Here is a couple pics...sorry there not that close of a shot.....:beer:

That is a Motocraft (Ford) "3G" case internally regulated alternator. I've had it rebuilt to produce 200 amps at 1600rpm. I'll get a true reading of the output once I got it on the test stand.
I was thinking it was a 3G but wasn't sure. Is it the Taurus style, Mustang style or other?
I would also like 200 amps capability!

Here is another solution using 3" tube, no aftercooler.
Yours looks exactly like mine. I bored out the hole to accept 3" thinwall aluminum, and tigged it in place. I needed it bigger for the 3" piping required by the powerstroke intercooler.

Think of it this way. Try blowing in a paper towel tube. OK, now try blowing in a megaphone. There about the same size where your mouth would be, but Which one is easier to blow in???

Yes but would the added volume of the larger tube cause loss of lbs and/or intake velocity? I guess if you have enough turbo it would help fill air/air aftercooler? Do you have before/after boost readings? I may have to break out the Big Chief and crayons for this one. I have the JWAC so wont help me any.
Just wondering, Carl

yea, your gunna lose some psi but you will be able to flow more cfm, thus get more air in the motor.

Would larger intercooler and intake piping increase "turbo lag"? I'm thinking the increased volume of the larger intercooler and intake piping will take longer to pressurize. Thus, a delay before the engine will see increased boost and air flow.

Yes, a little bit, but it usually isn't very noticeable unless it is a fast acceleration type application, like a drag car.
