Egr?

[SC Grizz]

Okay, so I've got a couple thousand miles on WVO now and all is well. So now I am thinking long term and have some questions/concerns about the EGR and the effects of wvo on that system.

Are you guys disabling the EGR valve?
What is the best way of disabling it?
Is there anyone who has a lot of miles on wvo without a disabled EGR?

As info, I'm running a 2006 6.0.

The way i deal with this - and i beilieve it to be the easiest - get the SCT Xcal3 tunner. Contact Innovative Diesel and talk to Eric. He has high marks for his custom written tunes. Decide what tunes you want and ask him to write them to disable the EGR function.
Kill two birds with one stone - get more power/fuel milage while disabling the EGR.
You wont believe t he power the SCT will unleash in your 6.0...easily get 425 - 450 HP just with a tune. I runa tun called Street Looney as my daily driver and its awsome on power, smokes like a train when i want it too and increases my fuel milage 3-4 mpg.

Clay do you have studs in your truck? Seems like I've asked you that before, but couldn't remember. 425-450 HP is pretty hot...wow.

Don't know anything about the EGR thing. Can you guys tell me a little more about why you disable the system? If I'm not really all that interested in performance changes, will my 7.3 continue to run OK on WVO for lots of miles just the way it is? Thanks - Patrick

No i do not and my custome tunner knew this so he wrote my tunes so i wouldnt get too high boost pressure which would compromise the head bolts.
My boost never goes over 27...it should be safe to about 30-32.
Yes, my truck is pretty hot for just a tune and exhaust. I do have the Zoodad mod but stock intake. I haven't run it on the track or dyno yet but i would imagine i will see a low 14 second 1/4 mile....maybe a high 13...not bad for an 8k lb dually in my opinion.

EGR was only and issue with the 6.0s...don't think the 7.3s have an EGR valve.

Thanks Clay. - Patrick

You would have a factory freak if you ran anywhere near 13s with that truck on stock turbo and injectors.

My tune makes a lot of power too... but in reality my truck probably went from running 17-18 second 1/4 mile times to 15-16 sec times.

Take it to the track, then throw some more money at it.

Then in that case i have seen alot of factory freaks.
i don't think 13s is a reality but 14.5 is....seen it before with an SCT, exhaust, zoodad, etc.
Maybe you just need practice launching

Ouch... I have a slow 7.3... on 40" tires...

Sounds like I need to pony up the cash and do that....along with gauges and exhaust too. Now I just need to find the cash.

Back on topic...

So does running WVO have any more severe effects on EGR operation than #2 would? Gunk it up faster?

Thanks!

Jack, I think anything would be slow on 40" tires...haha!

The 7.3s are much more expensive to pull big HP out of and the 40" tires will cost you an easy extra 2-3 second i would guess.
I have 4:10 gears, auto tranny, stock tire size so i can literally roast them till they pop if i have an extra grand for a new set. Don't get me wrong, my truck isn't fast compared to alot who have larger turbos, injectors, big oil...etc. But its fast enough for me.

sorry for the hijack
The consensus of all 6.0 owners (most of them running #2 diesel) is that the EGR needs to be gone...period. I had issues with mine before i started using vegi. Replaced it for like 350 bucks. no more problems with it over next 2 years but then i got my SCT tunner last Dec. and i shut it down so it can't stick open.

Keep in mind that tuning just shuts the EGR down. Blocking it off is another step you can take to avoid problems. I have heard that it is unlikely but you can still have issues even with it blocked off (rupturing or something). It seems the only true way to remedy yourself of EGR issues is to delete it completely. When I had my arp studs done (under warranty:chuckles they also replaced the EGR, blocked it off and replaced the oil cooler. I had to drive a few hours to have that work done but hard to beat for $100 deductible. My local dealer said what problems when I inquired as to head gasket issues on the 6.0

Thats a heck of a deal!!!

There are nice videos on youtube of a guy comparing the 7.3 to the 6.0 and he said that most of the problems on the 6.0 are EGR related. I highly recommend watching that entire series, there are 6 parts. He covers everything regarding the EGR from a #2 perspective.

If you kill it with a programmer, you shouldn't run into any problems. Isn't the EGR primarily for NOx emissions? Doesn't VO produce significantly less NOx than #2?
