So You know that EGR Spacer on EFI's? Well with the EGR disconnected those coolant passages just go to waste. I'm wonderin if it would do any good(probably will) But if it could do too much bad to run it's own little intercooler system so it's like an air cooler? Cold air is good right? but could to cold a air for the motor cause some issues?
Don't think there's enough volume to really do anything and the air is probably moving too fast to cool
well i know the original point of the coolant passages was to get the car to warm faster. like the old tube comin off the manifold to the air box. And to keep it running at the same temp as the motor for the best A/F mixture. But I guess I'll give it a try and see what happens. unless someone tells me i can potentally blow myself up. or worse. blow my new motor up.
the surface area is too small to cool the amount of air that will be going through there. the egr has temps over 400 degrees. that why ford cools it. if you put some sort of coolant through its going to be ambiant air temp wich is what your sucking in anyways. and if you use ice water you will be at 32 degrees for only about the 1st inch of the the intake track. the intake runners are 18" if i remember correctly and then plunum volume is huge between the runners and the egr spacer.
So what would just taking it off do? I know intake spacers, putting some on and taking some off changes powerbands and adds power sometimes? I don't know if shorter intake track what that would do.
just put a nitrous port on it' If you make changes without getting it tuned it's kinda silly. Especially a huge change like removing the EGR system.
On the efi 5.0's just unpluging the back line to the egr will set a code 33 and the ecu will disable the egr system and use fuel and timing maps without the egr.
SO this could also be leading to the poor mileage because without the O2 sensors in the right spot in doesn't have the right fuel map? Makes sense...
