Thread: Egr w/fsic

I have a full size phenolic intercooler and the egr works just fine. had the supercharger off multiple times with no buildup on the intercooler. a properly functioning egr will support higher gas mileage.

I'm curious as to how it will support higher fuel mileage.

The EGR recirculates spend exhaust gases back into the intake...there's a little unburned fuel in there...so that gets reburned. There's no/very low O2 in the exhaust...that cools combustion temps. Is it a dramatic fuel mileage thing? Nope. Does it do its job? Yup.

Eh, maybe by some minuscule amount perhaps, but can't imagine it would be noticeable really. I do know how the system is designed to work, I have a background as a GM technician for 8 years. What part of NC are you at Sven?
