lower egt's

What is the best way to lower EGT's on my 02 dodge cummins? I have 40 hp injectors, edge juice with attitude, FASS fuel system, 4 in exhaust, turbo from a 6 speed truck, and water methenol injection but im still smacking 1500 degrees when i mat it on level 5.

Turn your box down, lift your foot up, of pony up for a new turbo. Better be careful with that meth stuff on a stock head also.

They are not pre-tapped to my knowledge.

Too much of or mixed to strongly will cause a signifcant increase in cylinder pressure and pop a stock head/ head gasket.

I have personally never seen a truck running water/meth keep its stock HG for too long. I would at very least stud it.

Back to the original topic, Water/Meth doesn't usually drop egt's that much, its decent for dropping them if you are right on the cusp and want to bring them down just a little. That turbo isn't a whole lot better than your stocker. Yes its better, but not much. I've got pretty much the same set up, minus the W/M and I can tag 1600 like its nothing.

You really should get a bigger better turbo, But here is where it gets tricky. Unless you set your truck up right, if you go with a bigger turbo, you are going to lose some street manners and spool up, and it won't be very towing friendly.

What kind of terrian is it where you live? And what type of yota are you hauling? I'm building an 82 pickup right now.

Well first of all the dodge I'm referring to is actually a friend of mines. I have a 06 dodge 2500, 6 speed, with just a straight pipe and an edge juice with attitude.
As for the toyota, its an 81 with 38in boggers with twin transfer cases, longfield axles in the front, 5.29's in the toyota diffs. Springs are all-pro 4in in the front and 63'' chevys in the rear, with a full exo cage, and a mildly built 22r with a weber carb, and bead locks. What kind of yota are you building? We mainly wheel on rocks and trails. We live just outside of charlotte N.C. and the best place to wheel around here is Tellico but its a good 4 hr drive.

Me I'm about 3 hours from the Rubicon, so thats where I usually go, and I do some wheeling in So Cal too. Mine is an 82, right now its stock, but I have a pile of parts that are going on in the next 2 weeks. 35" Mud terrains, Waggy 2.5" lift springs for the front, 63" chevy's in the rear, 5.29's, Full hydro steering, Fuel injection conversion for the 22r, and then I'm gonna start building an exo. cage. I'd like to 4 link it and throw it up on something like 38's and also lower my ratio's via a dual t-case set up, but I can't afford the longfields right now. My dodge needs a trans, and I don't want to break birfs all the time, so 35's is all its gonna get for a while.
