3 Piece manifold and EGT's

[Powder Extreme]

I just installed DDII's and the PE Comp box my egt's are through the roof! Those of you using the 3 piece manifold; how much did it lower your egt's? I must say the box is alot of fun for the few all to short seconds I can use it. It'll turn day into night, smoke baby smoke!

The manifold isn't gonna change your temps one bit. You're gonna have to start changing exhaust housings(or go HX40) on your turbo to get the hot air our out.

Mike R--hit it on the head---anyway I hit 1733* at the sled pull and the truck is running fine and I've seen HVAC's--well how do I say this--well you know his head after he pulled it off and these things look like they can take more than we give them credit for---not that you should go out there and run 1400-1500* all day but for 1/4 mile runs or sled pulls --put the hammer down is what I say--but of course prudence always pays--you do it and blow something it's your dog to pet--just be smart----chris

Water injection?????????????

Why isnt anyone with excessive EGTs in 1/4 mile or sled pulls injecting water or water alcohol?? This has been done for YEARS in diesel tractors in pulling events. There is no mistery to it it will cool excessive EGTs and add HP. With the right amount of water or alcohol added you can add all the fuel you want. VROOM VROOM!!

 

[csutton7]

i've heard that water injection robs some HP--it really doesn't matter to much to those mega 1500hp and up tractors but for us well it might be a different story--now about adding alcohol with the water may be a different story--someone in the know will have to fill us in on whether it's a viable thing to do--but if just water robs me of some HP I ain't gonna do it----chris

Do you guys actually have first hand knowledge as in do you have the 3 piece manifold on your truck? I'm trying to avoid going with an HX-40, too much lag between shifts while towing. And after reading all the horror stories about the "modified" HX-40's blowing up, I'm not gonna buy one of them. I read an article yesterday about a guy who put water injection on his farm tractor 16 years ago. Says he uses 2 gallons an hour less diesel, and doesn't need to have the tractor throttled up as far to maintain speed. So I would say it doesn't hurt power at all. I personally don't see how it could hurt the power. The cooler the intake air, the more power you will get from it, within reason.

I have an ATS on my truck and if it does lower the EGT's I don't think it's anything to write home about---now my report on the water injection robbing some HP came from a couple of the diesel guru's one of which has a big ol' smoker pullin' tractor and the other who's got a mega HP cummins--so I don't know what to tell ya on that end except I'm sticking with what I heard from these guys--now maybe there's different ways to do it and you're talking one system and I'm talking another--I don't know---we know it'll help to lower the EGT's which will allow you maybe to use more power, but whether or not it produces a power increase by itself could be another story---need someone to chime in who knows this stuff----chris

Since I added my modified Banks 14 cm2 turbine housing at the same time I added my modified ATS exhaust manifold (and both were ceramic coated no less), it would be hard to accurately comment as to an EGT reduction attributable to the ATS manifold only. The combination did reduce EGTs though. A properly engineered 4", mandrel bent exhaust system will help reduce EGTs too.

This topic has extensive prior postings try a search on EGT.



I read and found personally that the Psychotty intake and 4" exhaust are good for about 250-300 degree drop in EGT's. After that, another option is increasing the size of your compressor housing only if you don't want the HX-40. Personally, I love my HX-40, but it's with an automatic and non-Majesticized. Talk to Lawrence at Diesel Dynamics, he's got the knowledge and products to help you.



Have fun!!

Thanks for all the input guys! I've already got a scotty style airbox, 4"DD exhaust and a 16cm housing. It seems the only thing left is an HX-40 but I just don't want the lag. I met Ken with Bully Dog and looked at his ram air hood, VERY TRICK he said it helped lower the temps as well, gotta have one. Time to start savin, maybe tell the girlfriend to get a better paying job

water injection

I have used water or alcohol injection on many differnt diesel engines. A 1700 hp 436 ci international I6 that would turn 5500 rpm to a 414 ci that is at 300 flywheel hp. And the water or alcohol ADDS power. Yes you can add two much water cool the fire and have less horsepower. Add the correct amount of water and you will have more useable power. By useable power I mean you can keep your foot in it. The 5 second blasts are fun but if you are limited to a few seconds by high EGTs what is the point of all that wild power???????? Have you ever noticed the power differnce when pulling at cooler more humid climates? Why is this? The higher humidity air is a cooler and more compressable air. Water injection is not a new idea used just by 1500 hp tractor pullers. It was pioneered in 1909 and later used in superchaged fighter aircraft in WW2. Would the pilots have switched on water injection if it had cost them power? Now admittidly the main reason fighters used water injection was to supress detonation but a widly known benifit was MORE POWER!!!! The systems can be very simple or very complex. The simple system is a tank that can withstand manifold pressure and hold water. You simply have a small spray nozzle before the turbo the line goes to the bottom of the water tank. You pressureize the tank with a line from the pressureized manifold. When boost is achived water is delivered. The complex system is Hobbs switched at the manifold to a 200 psi pump to a spray in the intake or before the turbo or both. Next time the truck is on the dyno take a Misty mate and spray water into the turbo inlet watch your EGTs. Take note Water does NOT compress make sure there can be no delivery to the engine when it is not running . The fine tuneing can be done on a dyno or on the street with a load. The alcohol injection on my 300 hp tractor is so effictive that there is a 75 hp gain and a EGT LOSS of 200 degrees!! You cannot do this sort of gain on just diesel and not have higher EGTs Remember one of the main reasons your engines have high EGTs is compressing air heats it. The turbocharger is a very effective compressor but when it compressis it also heats the intake charge. Take 200 degrees out of your intake charge air and you take 200 degrees out of your EGTs. . Simple.

Hey Powder, didn't you mean to say, Ken of Diesel Performance of Utah who sells the Air Bulldog induction hood? Doug Hofeldt of Pocatello, ID designed and builds these hoods and all required induction components.



All I can say is AWESOME product! I've had one on my black Sport for just about a year now. If I was going to purchase a new Ram you had better believe that bad boy would be transferred to the new one!



I will post some pics of my tricked out Air Bulldog induction components as soon as I have them finished and installed.

 

[Powder Extreme]

John, you're absolutely correct! I read what I posted after the fact and OOPS. I figured somebody else would catch it. Ken is with Diesel Performance and has a Bully Dog hood and air dam on his truck, very cool setup!

There you go again Powder...

If recited it correctly all four times you get 10 points.



Seriously, the only reason for the correction is I don't want other members to think the hood can be purchased through Bully Dog Technologies. In fact, if I'm not mistaken, Ken refers all potential customers directly to Doug Hofeldt, designer/fabricator of Air Bulldog induction hoods. Doug can be reached by phone at (208) 232-2469 or by Email at -- email address removed --



One other thing, Doug is one of the very best vendors to deal with. If I told you the story of Doug going the extra mile to ensure my complete customer satisfaction you wouldn't believe it!

I give up! LOL
