Upper Intake/EGR question
With all the talk about the intake spacers and lowering the intake air charge why is no one doing anything about the real heat source??? After a afternoon drive I did a little temp checking. The center of the plumn and was in the 140~150 range, at the TB it was around 130~140, the good old Eaton was around 160~170. And the upper plumn right at the EGR was well over 200
The EGR valve itself was over 220! This heat ended up moving throughout the whole plumn, and probably down into the blower just as much. At the very least I would think you would want to make a spacer to prevent as much of the heat as possible. If not remove it; which brings me to my main question; who has, and what are the in's and out's of removing the EGR other than it thoughs a code?

The EGR system is there to reduce NOX or oxides of nitrogen. this is done by LOWERING combustion chamber temperatures by recirculating spent exhaust gasses into the combustion process. adding already burnt (inert) exhaust gasses into the combustion chamber allows less room for fuel (air/gas). This "reduces the amount of burning in the cylinder" and therefore a smaller fire equals a cooler fire. the cooler combustion chamber temps produce less NOX.
the main drawbacks of removing or dissabling the system would be:
A. it's illegal
B. you are creating more airborne pollution
the main advantages? really none that I can see. The EGR valve is inoperative at idle and during WOT, so it doesn't affect acceleration or horsepower that I can see.
however, the idea of a phenolic spacer is somewhat interesting as this "could" keep some heat from the egr valve housing and egr tube from transfering over to the intake plenum itself.
the idea is interesting, but I seriously doubt that the amount of heat reduced would translate into any real hp/tq gains.
just my .02.

computer chip to use more boost and which isn't carb certified = illegal in CA
Long tube exhaust = illegal
