IPResearch EGR Valve Plug -- anybody ever used one?

Seems like it would be an easy to install product, would guarantee that no ERG gases are getting routed through the intake.
Quote:
IPR EGR valve bypass plug allows the EGR valve to be bypassed. This bypass plug allows the use of IPR's Extreme Duty EGR cooler or the OEM EGR Cooler in your 6.0 and blocking or bypassing the exhaust gas from entering the intake manifold which performs like a EGR delete while keeping all emission devices intact such as a EGR cooler. This is a solution for the weekend racer or sled puller to take advantage of a EGR delete while still ensuring that their vehicle is smog compliant.

The EGR valve can be easily swapped in and out by removing the 2 mounting bolts.

IPR EGR bypass plug is also a great diagnostic tool to test if your EGR valve may be defective by simply installing this bypass plug.

seems like a good idea but id be worried about the trapped gases in the egr cooler. seems to me that it would make the coolant pretty darn hot while its going through the egr cooler. i only say this cause usually the exhaust gases are moving through the cooler and heat transfer is pretty quick, but if its not moving id imagine it would heat soak...
someone PLEASE correct me if i am wrong!

With the plug, your dead heading the exhaust gas flow. Take a straw, hold your finger over one end, now try blowing thru the straw.

Well I understand that, but wouldn't it heat up the coolant even more since it's moving and exhaust flow is just dead headed? Coolant is still passing through the cooler...

I'm no expert, but I'd guess it'd actually heat the water up less. Like you said, the water is moving, the exhaust isn't. Meaning it's not bringing "new" heat in at a constant rate. Someone correct me if I'm wrong.

think of it like a 3 sided building and a cold windy day. Walk inside and instantly there is less wind (and windchill). Now open a door on one of the closed walls and it instantly becomes colder.

Basically the exhaust air in the EGR is trapped and stagnant, it will get hot via induction (being connected to the hot up pipe) but the hot air will no longer travel through the EGR.

Question as I read this thread.

The EGR cooler still has coolant flowing through it...well as long as it is not clogged. Correct. So you still have the coolant pulling heat out of the EGR cooler...but it is dead ended?

Two...it cant have more heat coming into it dead ended as the hot gasses passing through do not in and of themselves cool anything..they are supplying the heat. I understand it is a dead end and so if no external cooling jacket was there then you would have a serious issue with dead end heat build up...but again the coolant still passes through....right?

Also the comparison above is comparing cold air moving into a dead ended room with no external cooling. Rather the comparison would be hot air passing into a room with an external cooling jacket and so...does it do a better job keeping the exiting hot air cool as it exits...or does it overheat the room as once it is a dead end. There is two different applications in this comparison since the primary purpose of the coolant jacket is to cool the gasses as they exit correct...but they have been blocked. So...the coolant is now only really cooling the physical cooler itself...basically...am I correct?

It is like trying to take a hair dryer and blowing hot air into a soda bottle. Once the internal pressure of the bottle builds to a specific point the incoming air does not make it to the dead end it actually enters just a tad and is blown back out by the back pressure. Better yet..take an empty soda bottle and take a drag of a cigarette ( or a blunt if you like) and try and blow smoke in the bottle and see what happens..verses if you cut a hole at the other equal the size of the bottle mouth.

I am not trying to argue...rather just trying to get an accurate idea of what is going on with the EGR cooler dead ended.

So the only possible gain is by preventing hot gasses from EXITING the EGR cooler and going to...what...I forgot...thought it was the Turbo but I have not torn into mine and my 7.3 did not have the [email protected] attached.

The cooler still has to pull inductive heat from the cooler so there would be no gain from a coolant side...but probably not an issue to begin with.

I would have thought that if a $75.00 plug would do the same as a complete delete then most people would have gone that route?

I suppose the answer is from someone who runs a plug and what have they seen.
