Eek! So which is it to be? Is it the impeller (cold side) or the
turbine (hot side) that carries the variable vanes? Some say the cold,
some say the hot. I have found only one site dealing with these babies,
but haven't found the time to go through it yet. Perhaps I should.

While at it, I have another question to throw out onto the list:

	What is the best method of control for the variable vanes?
	I hear a lot of these units have vacumm actuated controls,
	you can spot the VATN by a diaphragm housing around the cold
	side, but are there electronically controlled and actuated
	units out there? Just thinking along the lines of something
	far fetched such as a CIS to EFI conversion that takes into
	account the use of a VATN. :) *sheepish silly grin*
