How can I Lower My Egt's

I would test the wires at the ABS computer.  truck off, Use a paper clip to "jump" the connector at the pumpkin, then use a multimeter to ohm out the circuit at the abs computer.  

 

It should be VERY close to 0.00

 

I would expect your mph gauge to read before 15-20 mph.  that and the abs codes make me thing you have a wiring issue.  There is a junction above the drivers front tire that gets nasty and corroided.  

On the fender well?

Sure lol mine just hung there

Ok two things; 

 

First(yes I know I'm three years late for the vid, so sue me).

Wash it out with water...

 

 

(Please don't do this it will do damage to a diesel... Just trying to be a bit funny)

 

This actually can be of value and used if done properly. I would not use liquid water for starters. Steam cleaning is a great way to clean if you suspect buildup.

 

Second; If KBeckers charger has a 68mm turbine there will be little to no difference going to a 62mm compressor.

stock gearing on 35's and 6 spd i usually get between 650-750 cruising 65.  on setting 5 i can hammer the pedal and peg the boost to 31 and egt hit ~1200-1300 easy, i do that for a second or two at least once when i take it out just to heat it up and clean stuff. most the time im in setting 1

These are the EGT's I get for 80 MPH with stock gearing and 235's.

Quadzilla wide open I can peg 45 PSI of boost and hit 1,400 EGT's (no limits).

I often wonder how long at what temp it takes to help clean out carbon on the pistons and soot from the head. I know my first couple tows in the spring, after not towing all winter, will get some extra soot out the exhaust at 25+ psi and 1100°+ for a minute or two.

I can confirm the same thing as well. I'm going to be hitching up the RV soon in the near future and most likely see the same thing.

i thought i've read somewhere you needed 1200 for a good long while to clean them up. i know i have a 17 mile hill that is 4-7% with most at the 6% grade, and i can't stay at the 1200 EGT's long enough else i'm doing 80+ towing my 13K trailer. (good tuner) 

If i grab another gear 6th, then i'm worried about killing the trans.

So I’ve ordered new 4.88 gears, but was curious if with my s364sxe would be best with bigger Injectors, or if I could use it as my big turbo for a compound set up with my stock turbo? 

[AH64ID]

While there are twin turbos that use 2 S300 sized turbos I do no think that a 364 is large enough to be a primary for a 5.9L. 

 

I would get the 4.88's installed and see how it drives, and then go from there.

I promise the gearing will change a ton load of the EGT's really quick. 

[KBecker443]

I under stand the gears will fix the egt issue but somebody mentioned that my 125HP Injectors were too small for my 364 turbo so after I do the gears I’d like to use the turbo to its potential 

[AH64ID]

I'd still wait and see. I believe the comment about them being too small was made in reference to your ability to light the turbo.. that should be a fixed issue with lower gearing. 

 

From there see what your cruise and peak EGT's are, as well as towing. 

[KBecker443]

How can I identify what my axles are so I get the right gears? 

[dripley]

My 02 has a sticker in the glove box with the rear end type and gears on it. Other info also.

[Mopar1973Man]

Another way to just check is to mark your driveshaft and the tires. Now rotate the driveshaft until you make one revolution of the tire. The number times the driveshaft spins is going to be your gear ratio. So if you are a bit over 3 and half turns then you've got 3.55 gears. If your barely over 4 turns then you have 4.10 gears.

sweet idk why i didn't look there. i got it thank you Dripley

I think he is trying to determine the axle itself, not the gears. 

 

Should be a Dana 60 front and a Dana 70U rear, IIRC. 

[KBecker443]

what do you guys think about 4.56 on 37s?

[AH64ID]

For occasional towing they will be fine, but they won’t give you the street or highway advantage of 4.88’s. 

 

What’s your hesitation on the 4.88’s?
