Me and a friend made the exhaust in the shop. Just went to the parts store and got the pipe. Took the plug out of the top of the pump and gave it about 2 3/4 turns on the screw.
On the military 6CTA8.3 engine, it comes with a Bosch MW injection pump. The "top" fuel adjustment screw is off-idle fueling, so this will add acceleration off the light, and smoke during such also. But it only affects this portion. The screw at the back of the pump with lock nut is the fuel rack travel limiter, this will adjust the total HP of the engine. A governor spring kit for a Dodge Ram 5.9L with a P7100 pump will fit this governor, and can be used to raise RPM above the stock 2200rpm limit. The MW pump is only good up to about 300hp, and same with the aftercooler used on this engine. To target 400hp, one would need to switch to a Bosch P-7100 pump, a larger HX-50 turbo, and front mounted charge air cooler. Could also switch to an ISL engine from an RV or firetruck, as it is the same dimensions and bolt pattern, yet has stock ratings up to 400-450hp. A guy on SteelSoldiers is making that swap, along with a 13 speed Road Ranger transmission into his 5 ton.
FormulaBoat I screen shot your comment. Good info for my build. Question is? Can I see 450HP with an 8.3? Marine grade injectors, P7100, 3200# gov springs and can I use a HX50-HX55 turbo?
P7100 fuel pump and a HX50 turbocharger is what I used on my M931A2 for 450 HP/1,200 TQ.The HX50 unlike the HX40 delivers 35 PSI,and is used on the M11.
I never liked when they switched the exhaust behind the cab always thought that the ones with the stack on the left front fender made them look meaner also when the went to the squarish front they runined the cool factor but this is just an opinion.
Too many guys got disability from the exhaust noise that’s why it was put behind the cab. The old M35’s used to have the exhaust piped out between the tandems on the right side but were switched to the right fender mount due to to many complaints from people in the curb side
Daily Driven Diesels we had some boats in Diego Garcia that ran Cummins M11’s and they were loud and rolled coal. Whenever we’d go ashore they’d bring them to our ship and back them against the hand hold it with constant thrust while we climbed on. It’s sounded amazing echoing off the ship
How do I get 400-450 HP out of my 8.3 without fuckn shit up nd still have something reliable? Every video I see is a marine engine. I want to spin these damn axles without the sluggish hesitation. Any suggestions?
Thank you sooty. I have a 84 NHC 240 HP. Lousy up hills with the water tank I put on. I will use your suggestion. We Contract to Cal Fire for Fire support on fires in Calif. I have my water tender on my page if you are extremely bored check it out. HAHA. Retired FF
@YB49887 Too much?...I have a HX50 and a P7100 pump in my M931A2 with 450 HP/ 1,200 TQ.All else that also was changed is the fuel screw and governor on it to adjust the timing and RPM better.
The stack is cheater cut to shit. How hard is it to cut some pie slices if all you have is straight pipe or just order a few bends from vibrant? Not very that’s how. Take some pride in that, and if your going to go though that much work you might as well do it rite. I make turbo kits for a living and would be embarrassed to ship that out.
This whole truck was $3500 and I made whole exhaust out of a piece of straight pipe that was laying in a barn. There’s a time and place for expensive exhaust and this isn’t one of them. No embarrassment here. I’m not shipping anything out

+Andrew Homann Did you adjust the timing at all?
+GunGuy0007 no stock timing
That's some good fab work!

I thought all 8.3 had p pump, mw is from mercedes small engines no?
FormulaBoat dang I didn’t know Bosch made fuel pumps man that’s something new

That is really awesome I like it ! I bet it REALLY billows black smoking climbing up steep grades !
Sorry about the environment 🤷😂
That is awesome......man do I love that Black Diesel Smoke! 💨

You should make a video on how to turn the pump up
Good job with the stack
Lovely sound, in a motor grader is espectacular!!!
Sounds like that turbo is about to take a shit
Dam this truck sounds so good
That exhaust looks great and sounds even better
Are there any support brackets holding up the vertical pipe ?
I bet that thing really billows smoke climbing up steep grades !
Like 👍
very nice
Nice smoke show.
Awesome... can you show how you turned up your fuel? and what type of fuel pump do you have?
how did you take the plug out was it really simple?
Nice truck, but the correct spelling for your pipe is straight.
Which plug do i have to take off?
sounds just like a 12 valve
Listen to the L10/M11

I have 1990, how did you turn the pump up?
Serge Smith Look at the post above you and he says how.
Monel Funkawitz ? where?
What for tuning did you do to this, and where did you get that exhaust? Thanks!
Built the exhaust ourselves out of straight pipe. Just turned one screw in the pump
Aren't you worried about being pulled over for that smoke?
it only smokes if i want it to. My dodge is 600hp+ an you learn to drive nice

Bladen Rexroth 400-450hp is too much.. just turn the pump up a little set the timing correct and be happy.

12 or 24 valve?
Jake Vimont 12 valve 8.3
@@andrewhomann6684 awesome!!
why is your 8.3 smoking so bad?
Sean White I turned the pump up. The truck can actually get out of its own way now lol
U must have had a really boring day to make a video like this lol
