On cold air:  Bruce is correct (and I'll second the "hunh"), that cold air is
your friend.  The problem becums that cold air usually means a corresponding
reduction in boost pressure, especially when in the big leagues (20+psi).
 Air density is more important than air pressure, however, not all of that is
addressable by the IC alone.  Addressing the heat before the IC is just as
important.  Stock k26 turbos are hardly efficient dense air chargers.  An
efficient charger makes the IC have to do less work.  Charge air temps
increase as ambient air is pressurized, the IC cools by a percentage the
INCREASE in charge air temp over ambient.  Increasing the efficiency of the
pump, reduces the temp increase in charge air, hence decreases the work the
IC has to do.  If one does some calculations of this, an IC will have the
best effect on a highly efficient fan.

Secondly:  A wide range of single pass IC's are available, from 300Zt to 944T
to T-bird SC (your welcome graydon) to 91 200tq's....  Getting them to fit is
a problem, getting one more efficient than a Spearco is the second one.
 There are several "types" of "radiator" configurations of IC's, the
production cars tend to use the "less" efficient type than can be spec'd to
Spearco.  Lots of q heads have a plethora of IC's from other cars, getting
them to fit is a major job.  Compromising the "structure" of the chassis is
most often needed, whether this compromise is with stronger materials or not
(you can always hire Bruce for your defense).  Putting a better IC than the
factory equipped is a great idea, getting it to fit is always a problem.
 Making the stock 44 IC a single pass (ala 91 200tq) is probably the best
compromise next to the spearco.  Why?  Cuz it fits in the exact stock
location for air flow, and is a massive improvement over the 2 pass most 44
chassis cars have, btdt.  A major undertaking in fabrication for "another" to
fit, but hardly rocket science exercise.  And not a revolution, IC's, just
efficient at the job they do, or more so. Revolution -  would indicate a
grand change from the accepted practice of manufacture and theory.  Given the
effect of cooling charge air, is this really revolutionary Bruce?

What is, beats 2B at any venue, except my building.  One can see 2B for years
here.
