I have banks 6 gun and a cold air intake from banks and i keep noticing that my egts are getting really hot i have even hit 1400 a couple times. What do i have to do to lower my egt's. does ugrading the size of the exhaust help? (i was thinking MBRP 5 inch turbo back) should i do and egr delet kit. i dont want to ask my friends that i worked with at ford cause they have already kept there mouth shut on a couple warenty claims.

thanx mitch

 

a cat delete will help, and you really dont need 5" exhaust unless you have huge hp, 4" would be plenty big enough

 

are those temps pre or post turbo? both are way to hot (imo) get rid of cat and muff. SLOW DOWN will do more good then any. lol

 

i forgot to mention. my exhaust is straight through but stock size. my pyrometer is in the left manifold.

 

Best thing to do is to get rid of the Banks 6 gun - swap it for a SCT with custom tunes!

 

Part of your problem is that you are running tunes that really don't tune your truck, thus they rely on increasing cylinder pressures and/or overfueling(translates into higher EGTs).

Going to a bigger exhaust will present a different problem. That problem will be the lose of low end power(unless you really overfuel the ole girl) due to have too much pipe and not enough air/fuel to push through it unless you are really revving the girl.

If you have to go tuned at least do something that really tunes the truck. Properly tuned and properly driven, you can get a lot of fun out of a good custom race tune and not hit astronomical EGTs(although I have pegged out my 1600°F pyro before).

 

900 is safe for a post turbo probe. i "think" 1200 is generally the limit for pre turbo. there has been a lot of discussion about this, but continuous or sustained temps are more serious than a momentary spike. the difference is pulling a long steep hill wide open, as compared to you punch it to take off, or pass someone. generally a short burst of 1400 shouldn't be that harmful. if the rest of the engine is stock and the tunes are running that hot i would be talking to banks. i would also prob get rid of those tunes. they don't adjust your transmission setting to prevent it from slipping with the extra power. its not a tuned exhaust and plenty of people out there have not reported any loss of low end. they also haven't really reported any gain on the high end. about all you can hope for is a different sound and more noise, and a small egt drop. any power gain is from adding more fuel to take advantage of being able to get rid of slightly more heat.

 

You have to take into consideration what they are doing not to be reporting loss of low end torque on a bigger pipe. Are they rolling into the throttle or stomping on it? Are they running a hotter tune or a supposed "economy" tune?

Rolling into the throttle helps a lot with lag as well as running a hotter tuner. Stomp on it and/or running an economy tune doesn't help at all with this type of scenerio.

You also have to take into consideration, do they really know what to look for and how to correctly interprete what they are looking for?

Remember what you are dealing with here is expansion. Bigger pipe with stock parts and off the shelf tuning that more then likely is designed for people that just get 4" pipe isn't going to have enough exhaust coming through it to expand completely in the pipe and expell. It's just not going to happen. Now run a hotter tune that helps, because the nature of those tunes is to over fuel, create more exhaust. A person may or may not know that it's there with an extreme tune, doesn't mean that it's not there, it just may not register on the "butt dyno".

This would be more of a problem if like other diesels the 6.0 was geared a little lower, but it isn't. This would hurt us more if we peaked HP/TQ earlier and didn't match everything properly

I doubt you'll see a noticable EGT drop in this case for the same reason that "you'll" lose low end torque. It takes to long to expell the exhaust in this case. Now if you had more exhaust(say bigger injectors and/or bigger turbo), sure in that case, but not with stock parts or off the shelf tuning. It's not going to happen except in your head(maybe that's enough).

 

The only difference from stock to the banks 6 gun was that on the interstate i was able to pull easier. another reaso that i went with banks was because of the shift on the fly option, banks IQ moniter, and plug and play. i also noticed a 2 mpg better on the interstate. i calculated it at the pump not off the truck display. can you get multiple tunes on an SCT or something simular along with shift on the fly?

 

Yes to the multiple tunes with the SCT, NO with the change tunes on the fly. With the SCT, you can just leave it in the tow tune (or street or whatever) and use your foot to keep it calm! Another BETTER thing with the custom tunes and tuner is, the tranny is also in the mix. With your Banks, it is not! Shorter trans life.

 

And get the EGR system plugged or deleted. Both work but if you buy a kit it will be allot more money than if you unplug your egr valve, remove the egr cooler, and weld a plug to the hole on the up-pipe that feeds exhaust to the egr cooler.
