Help!
You guys have helped in the past, so here I am again.
2004 305/555 4:10's 6 speed
285/70/17 Cooper STT's
MBRP exhaust
Scotty Air III intake
Edge EZ set on level 3

Haulmark 27' trailer approx 7000 lbs.

Egt's will hit 1300 on any basic hill

What box is out there that has the same basic hp/torque 60hp 200tq that I can actually use with the above mods. I just returned from Cooke City Montana and basically I spent the entire time watching my pre turbo Egt's. I want usable towing power! Anyone with high altitude mountainous mod experance?

Please do not just tell me to use the lower levels, I know this will help, however I would like to maintain the higher power levels. Any box recomendations?

THanks in advance

 

I'm kinda curious as to whether it's making as much boost as it should. Got a boost gauge? What kind of max boost numbers do you see?

 

As your temps increased did you raise your rpms to allow more air to cool the turbo?
I have not towed with my EZ yet but I will not tow above level 1 and I'm towing more weight
than you (10K lbs total family, gear, 5er loaded with 40 gal of fresh water) Just now installing
my gauges (today) so I dont know what my egt's have been yet.
I've heard dropping a gear to raise rpms allows more flow to cool. Do you have a boost elbow
installed with your Edge EZ ?

 

have you done a better intake and exhuast system?

 

I do not have a boost gauge, I have not installed the boost elbow for the EZ as it seems from what I have read on here that it may be detremental to the turbo. 4:10's are the problem with grabbing a lower gear, at 70-75 you are turning to many r's to hit 5th.
Thanks

 

Boxes with timing advance will help from what I've seen on here. Specifically the Banks six gun and the Edge Juice/TST. The edge and juice do not add pressure. But - you can stack your current ede box with them if you would like to hot rod. If a timing box doesnt help, and you are keeping the revs up and not lugging the engine then you will have to look at moving more air. Exhaust, air box modifictions, better turbo are the next steps.

 

This may sound bad, and I'm not trying to offend you. But, what I'm about to point out is hard to take w/o being offended. So, with the warning done...You're towing on level three, and insist on doing that. Yet, you have no boost gauge, which is one of the most basic monitoring devices out there. Furthermore, you have not installed the one device (boost elbow) that comes with your box that's intended to cool egt's. The way I see it, the basic problem is not technical-it's in your approach. Again, I'm not trying to insult you. I'm NOT calling you stupid, I just think you're approaching this all wrong.

The boost elbow may eventually damage the turbo-I don't know. But, to insist on towing on setting #3, without the boost elbow, and not even have a boost gauge? You're really asking to damage something. Yes, you may drive with your eye on the egt gauge. But, you keep seeing high egt's. That's a message from your truck to you. It's saying that you are trying to do something that's unreasonable. As you're seeing, you can't have safe egt's towing with your box on 3 without taking any real steps to lower the egt's. So, you ask us to not tell you to reduce the setting on your box. Ok, we won't. We'll let your truck ask you instead.

I know you want to tow on setting 3. But, you may have to just accept that doing so with your current configuration is not reasonable.

 

mro,
Something doesn't seem right to me. I have the same engine as you, pull 10000lb trailer, run VA C-3.2 on level 1 stacked w/ EZ and can't get my EGT's above 1250 WOT pulling trailer up hills. AND I havd stock air and exhaust.

 

GreenZ, I'll bet you've installed the boost elbow. mro, install the boost elbow. I've never heard of a turbo problem as a result of the elbow. You might end up melting a piston without it.

 

EGT's are a result of balance between fuel and air. If you add more fuel, (with your EZ) you need to add more air (with the elbow). The stock 21 or so psi of boost is ok for stock fueling, but not enough for the fuel you are adding. I imagine with the proper elbow for your EZ, your boost will max out at 27-29 psi, your EGT's will come way down, and you might even gain enough power that you don't have to tow at level 3 anymore.

 

What is a good safe range to have your EGT? We stress relieve our welded high carbon steels at the temperatures you guys are talking about? Wont the pistons, exhaust manifold, or other steel components deteriorate in strenght after prolonged exposure to those temperatures?
I dont know what it does to aluminium.

 

I've towed on level 5 and the only way to get my EGTs to 1300 is to mash my foot to the floor with the trailer loaded. I added a Banks 4" downpipe along with a BHAF and it lowered my EGTs about 100 degrees. The boost elbow will also help with your temps..

Also, stacking boxes is supposed to help with your EGTs... The beauty of stacking boxes is that you get the extra power you're looking for without raising the EGTs to a dangerous level. From what I've read, you set the pressure box to one of the lower settings and the timing box to the middle settings.....

 

I have towed from NY to FLA with the EZ on level 2. No elbow, and my egt`s never went above 1100. thats with 8,000 lbs maybe 9,000. And i am dumb...i like to drive 75 MPH while towing. I know there isn`t many hills on this drive, but she stayed nice and cool.

PS, The total time my EGT`s were at 1100 was less than 20 seconds....they were mostly down around 700.

 

I read all this in a hurry but didn't he say he had his pyro pre turbo?? if so does everybody else who is quoting their exhaust temps? if not that can be a large dif!!
