Default expected machine shop costs [superram mod]

I want to have some extra aluminum welded to the interior of the plenum (the outer 8 most bolts, 4 on each side) to provide a little more clamping force and help prevent stripping of the threads. I also want to do the same process for the inner 8 bolts, but have the runner flange welded/tapped instead so the bolts go in from inside the plenum. I would then cross-drill those bolts to accept a retaining wire or small cotter pin to prevent them from loosening out into the plenum and being eaten. I think others have done this, but what should I expect as far as machine shop costs are?

I plan on looking around but would like a good starting point for the minor welding/drilling of the bolt holes. I would even tap them myself once they were drilled properly (and to avoid potential confusion...)

Why don't you just stud the plenum ?

I'm using 1 1/4 inch long 1/4-28 x 1/4-20 auveco studs on all 16 of the plenum holes and 1/4-20 kep nuts from below. Easy to install and no stripping.

I posted a few pictures about a month ago, if you run a search.

some welding on the plenum should be pretty cheap (less than $50 I would think)

Probably expensive if you let them do most of the work. But its very time consuming on your part. Depends on which route you wanna go
