Um I dont get it...
Why do people with EGRs block them, and people with out EGR's put them on?

I think the mileage suffers because of not using the recycled air, and the pressure of the exhaust, so your intake works that much harder.

EGR stands for Exhaust Gas Recirculation. So what do you think it does? It recirculates exhaust through the engine. Is exhaust clean...no. The exhaust makes the blower, intake manifold, etc... in the engine dirty. So if you block it off none of that will be dirty anymore. We removed it on the GTP to keep the intercooler clean because according to Zooomer with the EGR connected the Intercooler core needs to be cleaned every 10,000 miles, without the EGR connected it only needs to be cleaned every 50-100,000 miles. A HUGE difference. So basically you take it off to keep the engine clean.

Because what does you exhaust have left in it...a little bit of fuel. When the exhaust is recirculated the engine can use the little amount of fuel it didn't use before over again, so you would get better gas mileage, not much better but a little bit. We didn't notice a loss in gas mileage at all in the GTP for some reason, if anything we noticed a gain. I wouldn't worry too much about it.

i think that air also has water in it from the incomplete combustion reaction, wouldnt that about negate the fuel left over?

Recently installed my ZZP EGR Bypass kit. All it is a 1/4" thidk square of aluminum with a drilled and tapped hole for the original bolt.
Now my intake will stay cool and clean. :banana: http://www.cardomain.com/memberpage/383040/5

Oh.... no codes were set and the SES light has not come on. :lol:
I can feel the power.... :headbang:
I'm not worried at all about burnt exhaust valves......burn baby burn.. :bouncingflame:
I disconnected the EGR in all my other cars and haven't had any trouble over 30 years.
