For the sake of engine bay access, as well as minor weight reduction, I'm about to delete my smog system.
This is on a Ford 5.0L. The plan is to cap off any vacuum lines, plug the hole in the back of each cylinder head, plug the tube on the H-pipe, close off the egr hole on the egr spacer in the intake system, then finally use an egr eliminator in the connector to remove the CEL. Unfortunately there will be a constant code saying the egr is closed, but at least the CEL will be off.
I had a few questions, though.
I've heard that because there is no more inert exhaust gas entering the intake system and as a result not entering the combustion chamber, the combustion chamber temperatures will rise as there will be more oxygen in the cylinders. This only happens during casual driving as the egr is designed to close at WOT. Does anyone have an idea of how much this will make combustion temperatures rise? My car is exempt from emissions, but will the higher emission levels due to higher combustion chamber temps affect performance?
I know the basics about this, but I'd love to know what exactly will happen and how it will exactly affect driveability. This car is basically a toy that I drive to work on nice days, so it doesn't need to be too practical.
