Need to lower EGTs..what to do?

[amberjax]

I need to lower my EGT. What are the ways to do this beginning with the cheapest. I have already have a Tymar, 3" downpipe. The rest of the exhaust is stock. I just bought a new camper and the motor feels ok, but the egt gets high pretty quick.

[94strokerace]

have you looked over your uppipes and manifolds for exhaust leaks? an intake leak will equate higher egt's as well.

have you talked to Jody yet? he may be able to do something in your tuning.

if nothing else, start with an intercooler.

[amberjax]

How much will an intercooler lower the exhaust temps? I've also read that gutting the EBPV valve would drop the temp some too. Is that true?

[bamboo]

gutted EBPV droped mine like 50degress!

what are you running for EGT's now???

1200º is still safe, sucks down the fuel but its still safe to run all day.

Since you bought a new camper, (assuming heavier) and you started the other thread about lower gear ratios,

have you tried altering your driving style? When are you having egt problems? all the time towing, towing up hills?

speeding up, or running one gear down with higher rpm, vs slowing down and running low rpm will decrease egt. The egt will climb the fastest when lugging the engine.

[amberjax]

The EGT get to 1200, and then if I let it drop down out of overdrive, the EGT goes back down. As far as driving the main problem is up hills. Of course all this was happening while pulling this "longer than I expected" 5th wheel through the mountains of West Va. and Va. 700 miles from home. In reality, probably need a bigger truck, but the truck really suprised me how it handled and rode. Just need to take care of a couple of things like the EGT thing to make me comfortable.

I never run od when pulling unless I'm going down grade or flat land and don't use it much then.. Even on flat land the egt's rise quick with little peddle pressure. Sounds like we pull some of the same hills we go to virginia & WV with the horses quit often. I don't have much trouble long as I stay out of OD.I know it is hard to do with the price of fuel but it seems easier on the truck all the way around

I try to tow in OD because I think that's what the manual says to do. The good thing is that I live in SE Va. so I don't get up to the mountains very often. I usually camp on the eastern shore or hatteras. Good to know that towing w/o overdrive on hasn't caused you any troubles. Thanks

Pretty sure that the recommendation is not to tow in O/D, especially if the topography is hilly. It not only lets your EGTs climb, but your transmission is prone to overheating.

[Cratos]

If you cat is still there it is restricting and holding the heat. But a good custom tow burned chip will help. (Not one off the shelf.)
Intercooler will help but you will loose 1-3 lb boost without a chip.
The one I got from swamps loads the bottom with tones of torque and runs up the shift points.
With my mod’s, I pull 14.500lb 3 horse GN with weekender package. If I need t pass NP we run buy them. All Most every weekend.

he is from VA, unless mistaken, that Commonwealth has a fairly strict emissions testing. may want to look into this before hacking on the exhaust...

[tates97]

i'll pull the stupid card is your Tymar clean? I just replaced mine and dropped an average egt of 80 degrees. just something I noticed. Yall are prolly more diligent than I am...TAter

I was pulling about 5k up from Fla up to Nashville and back over to NJ and had alot of time to listen to the engine while pulling those hills, granted 5k isnt much but with the lift and the 35's you know its there. Any who I had no problem in the power department and I tried every setting on my chip and did not notice a change in fuel consumption besides it was alot The only difference was while running with the cruise on and in od it would drop out of o\d. If I was in 80 econo or 80 hp it wouldnt drop out. Then I ran several hundred miles out of o\d and the engine noise was killing me but my egt's were about 800 flat and 1000 pulling hills and the mpg didnt seem to change it used alot of fuel period. When I got to Bean's I picked up a new Tymar filter since mine was about two years old and did notice a drop in egts, maybe 50 to 80 like Tate said. My filter didnt look dirty but I guess when calling for that much air a clean filter is a must. I also asked Ryan what was better for my engine low egt's and higher rpm's or low rpm's and egt's around 1000 - 1100, he said rpm's will not hurt my engine at all and lower egt's are better. When I say high rpm's I'm talking about 2400 to 2500 for my set up and that puts me at about 70mph, but I'm used to the 1900 to 2000 rpm range, which is fine when empty or pulling light on flat ground like I did yesterday on my way to Myrtle Beach. I was pulling a small enclosed trailer with my bike in it and all of our crap, about 2500lbs rolling along between 65 and 70. To get back on track I pulled about 12k a month ago in my 40 tow program @ 65mph out of o\d and my egt's did get to 1200 a few times, but they climb very slow not like before my intercooler they would get there in a split second and drop quickly once you get over the hill. I have not pulled anything over 5-6k in the mountains yet to give you acurate info, but I believe I will be fine. Good luck p.s. I would change gears if I were you unless your pulling 15k or something

Before I went to BDP injectors I had a SD i/c, DP chip and .84 housing and it was a real well balanced combination. I couldn't get EGTs over 1200 unless I lugged the engine, boost was around 20lbs @ full throttle towing rpm ( 25 peak ) and response was excellent... if you are happy with your current power, this is a good solution, if you want more power you need injectors.
