The air pump costs maybe 2 hp at most, it is there to add air to the exhaust
to complete combustion, if you are hard set to remove it remove the cross
over tube on the back of the heads and plug the holes, Go to you local ford
dealer and ask for thermactor plugs.
The egr is actually an onboard octane booster, by removing it you may have
to retard the timing to get rid of ignition ping which will cost you power.
If your egr valve and thermo switch is working properly they will not cost
one HP and at wide open throttle it stays closed and no exhaust
recirculates. The big killers of performance were the lowering of
compression ratio and cam changes. You must also remember that the
distributor is calibrated for use with and egr and it will not run right
with out one. You can change the curve in the distributor but that is more
work.
If the engine is in good shape it will not pump carbon into the intake. If
it does then there is another problem.
