Re: Warping Plate (help)

Try mounting the flange with all eight bolts onto a piece of plate steel.
Torque it down good and tight without gasket of course. Start with each
tube and get a partner to heat as you bend, markoff, and watch for kinking.
Washing the heat all around in little doses seems to do me well. If it's too
far gone I'd just rebuild it from scratch if need be. Being such a critical
part thing about it. It might not pass tech on some tracks... Think if it
leaked and caused a lean condition at 8000 rpm if that turbo lags..That
engine is toast... Better off safe than sorry.

All the best,

its not that simple if the tube exiting the flange makes a real sharp
turn, aka "cheating the cut".

You could duplicate a manifold flange in heavy plate. That would allow
you
to have the tube protrude. Another way would to stack extra flanges as I
mentioned. If you can at least do most of the welding before unbolting
it
will help.
Another idea is to bolt it to an old cylinder head. You could also
bolt
left and right manifolds face to face with spacer plates if it was a V8.
Our little problem at work is solved for the future flanges by using
dogs and wedges to clamp two flanges together then let the welding forces
on
the two weldments fight each other.
Does the flange have to welded to the tubing on both sides??? It
sounds
like overkill to me. If your tubes are 1/16th thick you only need a
1/8th
fillet weld on one side to be strong enough.

yes, but if i bolt it down to another slab of steel how then do i weld
inside the flange exhaust holes if a piece of pipe is sticking out? the
tube must go inside the flange holes and welded around the inside of
the flange hole. i guess i'll need to go real slow. i will also not lay
a bead outside, i'll opt for some corner wedges to help support the
pipe to the flange.
