John - Per your instructions, I tried using a simple welding regulator
on my NO2 cylinder to drop the pressure to 40psi coupled into the
connector I have on the throttle body on my 2.1L.  At R&D Engines, in
Rossville, GA, it DOES increase rear-wheel HP on their dyno from 82hp up
to 142hp.  On the road, where I notice the greatest difference is is
hill-climbing, which was my main concern.  I can tell you that the temp
gauge climbs about an 1/8 inch going up our local mountain's 1.2 mile 6%
grade at 75mph, where I struggled to make 55mph (in THIRD gear) before!

Appreciate the suggestion.  I just can't see the advantage in spending
$500+ for the commercially available NO2 systems.  This NO2 injection
business might just be an attractive alternative to all this talk of
engine swapping!
