Started to siamese the intake: This is without smoothing it out with the large flap wheel

Will need a dremel tool to clean up some of the ridge in between

Nice.

The are the IHs that were machined to 36mm a few mm into the port, well I found out why they did not use them, the walls are thinner by about 1.5mm and so 36mm all the way through is not very easy....but the will do just fine siaimaesed.

Stil need clean up and take ridges down:

Now then try getting a 36.5 mm ball go all the way thru or 37mm go halfway,my own IH/plenum are this way.

I do 36mm ball go all the way thru.
Like you said they start to get thin.

Pete,

Does this mean that you must kill all of us now that we know this?

Lee,does the alumiweld work?

Dom,no i won't have to kill everyone for this info just saying what i have done to my own intake, have not lost low end at least nothing that shows up on Dyno sheet or seat of the pants.

The Alumiweld works if you can keep the parent metal at the required 730 degrees, which I had a hard time with. First one did not work, second one worked well, but I could have used more practice, first time I used it.

Aluminweld, bonds to the parent metal it is not integrated into to as with a weld. It however is very solid......key is how clean the parent metal is too, stainless brush and some acetone need to be used.....I probably could have taken more time in cleaning.
