["Mairs, James" <jmairs@cabletron.com>]

The IC on my Callaway Turbo GTi is VERY similar too the one in Stott's 4KTQ.
I am not sure about yours Stott, but the backside of my 'scoop' has a thin,
opening, large enough for small stones and dirt to bounce up and back out
the back side of the IC, rather than going up and into the IC core.  But
small enough I would 'imagine' to direct a majority of the air flow upwards.
I am sure you are loosing some airflow, but most of it should go towards
"least resistance" right?  And loosing small stones, dirt, bugs out a hole
in back seems better to me if you are driving this car everyday...

Just my ½ cent...

		For those who were at Mt. Washington this year, and happened
to be looking
		at the underside of cars, that is exactly how the
intercooler is on my
		Callaway.   Albeit, it is smaller than in the image in the
link Mark
		provided.  But it is located in the lower right corner of
the car(below and
		in front of the airbox, behind the lower valence and skirt),
with the
		airflow gathered by a scoop and passing up through it.

		The biggest problem I would one have to watch out for would
be the pressure
		drop across such a large intercooler, and the size of turbo
required to keep
		pushing enough air through it.

item...

		I picked up a copy of Corky Bell's book on turbocharging,
and in the book
		there is a picture of an intercooler mounted UNDER the
engine lengthwise
		across the engine bay.  The thought here is that you could
mount a truly
		HUGE intercooler in this space (I took a quick look under
the 4k, and this
		appears to be feasable with some clever bracketry).
Naturaly, it is best
		to weld some sort of an air scoop to the bottom of the IC to
provide
		enough air flow, but I would think that the slightly reduced
airflow from
		this mounting configuration would be gained in sheer square
footage?  Any
		of the physics pros out there on the list care to comment?
