Engine/Transmission (1998.5 - 2002) EGTs with new injectors??

[docterben]

Now that I went with the 300 HP Bosch injectors, and while I'm saving up after the VP 44 debacle for my gauge set, how careful do I have to be about EGT? I won't know how hot I am until the EGT gauge goes in, so am I OK around town? Unloaded on the highway? I know I should stay away from 15,000 lbs up a 6% grade (bummer) . Any insight from y'all who are bombed with gauges would be appreciated!

with my mods pulling a 6000 lb travel trailer last week 70 to 75 mph thru the southeast ( modest hills) we did not go over 900f.

Around town unloaded we generally see 4- 600f

I would suggest a boost fooler and intake mods.

I didn't see you mention a boost elbow or anything, so I'm assuming you're running stock boost levels. I would be very careful with that combo. Even a strong headwind could cause your EGTs to rise. You should be OK around town with no extended runs. Didn't see what part of the country you're in. If at high altitude, things could be worse. Of course, if you have a boost elbow and fooler of some sort, your situation would be much, much better.

OK, sorry I don't know this... ... ..... what's a boost fooler/elbow??

 

[MMoroney]

No problem. That's what this forum is for. If you look at the turbo, you'll see a rubber line with a 90 deg fitting at one end. A boost elbow replaces this fitting, but has a small bleed hole in it (I believe some have a different size orifice as well). What this does is raise the boost by keeping the wastegate closed longer. More boost, more air, less EGTs. However, you'll need some kind of boost fooler to go inline with the MAP sensor to keep the computer from seeing an overboost (greater than 20 psi) and setting a code. The boost fooler can be simple (Practical Solutions) or one of many aftermarket boxes, such as the Edge EZ that I have. I'm sure more folks will chime in, but that's the basic idea. Mike

I wouldn't worry about too much, remember your temps are the highest, UNDER LOAD, like towing, accelerating, accelerating up hill etc..... Then I would get the pyro gauge by itself, perhaps in a steering colunm pod.

You don't say in your sig if you have an auto or manual.

MMoroney is right if you have a manual, I believe if you have an auto you will need to put a turn buckle on the waste gate. Don't do either of these until you have a boost fooler. Most boxes have them built in but not all.

This is a REAL good reason to watch your EGT closely... This came from a recent TDR post.
