what about this is it bs?
the intake get INCREDIBLY dirty including the entire supercharger and everything else. I don't see how this doesnt hurt performance
1337, the EGR doesn't normally add AIR. It'* exhaust gasses that don't burn. AIR is combustible. That'* why it amounts to a vacuum leak and upsets AFR.
Also keep in mind the mild coating of EGR/PCV film on your rotors and case can actually have the effect of increasing the efficiency of the supercharger slightly.
ZZP sells the EGR kit primarily for the intercooled cars so the intercooler core doesn't get plugged up. A short burst of water injection would clean that right up though.
In a nutshell, exhaust gasses aren't combustible. That'* why they're used. Air is.
