I am getting ready to install a 3800 sc in my 85 fiero and I noticed the carbon build up in my Super charger and was thinking about removing the EGR. I was wondering what the pro's and Con's are to doing it and how you do it.

Thanks

Pros? There really are none except the less carbon intake

Cons? MPG, emissions

How? block the passage on the LIM and exhaust manifold, have it tuned and deleted from computer.

Just keep in mind you'll still get carbon from the pcv system, so it won't eliminate the carbon entirely. And properly tuning out the egr is more complex than just turning off the codes, fuel and timing will need adjusted to compensate for the increase in available oxygen while cruising. Egr on gas engines isn't used except for while cruising. (Diesels are a different story, egr is constantly in use, even during cold start idling to assist in warm up.)

Are you sure that the carbon you are seeing isn't the teflon coating on the supercharger rotors?
