I just finished an egr block on my 04 6.0. I only did it after blowing 3 coolers in 3 years, primarily because I pull a heavy travel trailer up steep grades. I also added an edge plantinum juice with attitude. What the egr block really did, in addition to increasing initial throttle response, is to run cooler, like 200 to 300 degrees cooler so that when I added the juice I could run at higher levels and operated below the 1200 degree max on the exhaust manifolds. I have heard my coolant boiling inside the egr cooler after pulling up a steep grade. Never again! But note, on 03-07 6.0's the cooler is under the intake manifold on the passenger side. Everything on top of the engine comes off and the best way to reinstall is to attache the cooler to manifold outside of the engine and put it back in as one unit. Say what you want about EGR coolers. On 6.0's they dont work! Block it off. You wont regret it and neither will your pocket book.

 

I'm with you on this one...

had one in today when the boost was hitting 28-29 psi due to sticking turbo the egr valve would open to get rid of the excess boost....

although i did have one in last month that with the egr valve open 100% DC my MGP was still over 27 but she ran like a rapped ape till i put in the new maf sensor....

 

I would delete it. Even on all my gas motors the first to be removed is EGR stuff. Exhaust has no place in the intake in my opinion. The only problem with an egr delete would be whats called EPA mode. It fixes the turbo vanes due to lack of egr gases in the manifold. Nothing a little custom tuning cant fix though.

And to dieselpuller, Id toss the edge and get you some custom tunes, especially if you have an auto. Custom tunes run cooler and the same or more power with safer cylinder pressures. Also edge does a horrible of retuning the trans, if at all, itll burn an auto up real quick.

 

Could you explain this to me?

I have never heard of an EGR as over boost protection, or any limit on boost for that matter. Are these fords running a VGT or wastegate?

Is the boost and exhaust back pressure that close?

 

Your correct. The pressure in the intake can push the egr valve open. Its not commanded open when it happens. Thats why if you do a poor mans block and put a freeze plug in the back of the egr cooler and get a tune to shut off the egr valve it can still open. Thats why its best to weld the egr valve shut if you do it like that.

 

I can see how they can say its overboost protection, but i dont it see flowing enough to make a huge difference.

 

I'm not saying id never delete the egr on my own vehicle my kit is on it's way, redstroker said it best in not wanting wasted dirty air going into the intake, i also have a set of gauges and know how to drive my truck and know what is in its safe limits but i am not about to do this to one of my customers vehicles who has no idea how to change the oil at the recommended intervals let alone keep an eye on his boost gauge...

upon acceleration once you hit max boost and let off the go pedal you get the flutter of the valve opening up to try to lower the boost in the intake. seems to me that it flows enough to get that job done to me IMO

the 6.0 runs a VGT type turbo.

the boost and back pressure are not as close as you may think you can easily hit 50-60 psi in the exhaust system while your stock intake or even heads are not going to withstand that kind of pressure..... at least i dont think so.......

 

Once....

 

Maybe I am not thinking right now, but if you have less back pressure than boost (and the computer has the turbo fully open for min boost), the turbo for the most part won't have the energy need to compress the air to start with and the problem would negate itself. ??? If you are at WOT the exhaust pressure will be up there and then you would be hard pressed to have more boost than exhaust, meaning the EGR would send exhaust in as opposed to air out.

This is interesting. I honestly am fascinated at this concept. I just haven't ever dealt with anything like that on the heavy duty side. Do you have engine protection on these? Where the computer will shut you down if it doesn't like what it sees?

 

Your drive pressures will never be less then boost pressure. You can get close to equal by running twins.
