Need help on how to get 500hp!! 12v

i just got a 12v out of a fedex truck and would like to make 450-500 hp and 1000+ of torque.Im going to use it in a daily driver/ toy that i will haul about 6000 lbs on flat ground 2 times a year. i will be putting studs on the head and getting a hi flow exhaust manifold, from where on i need help, it currently has a good 175 hp p-pump but was told the industrial engines had a different pump than trucks? i have a holset hx35 turbo and wondered it that would work for a twin setup or should i ebay it? Basically would like to know from some people what they are running. I would like to use what i have without spending more than 3000 on the engine.please be specific in your build-up,injector,pump, turbo, valve springs,ect so i can copy what you have done to the tee.O yea i WILL have an EGT to monitor exhaust temperatures. thanks in advance

yes i have read hours and hours on this forum and diesel mags ect, but it seems many people are still working on there trucks, i would like to see if anyone is done and would share what they did.Another problem is alot of statements like "bombed pump" or other 100hp sticks don't really give any info, what did you do to your pump? I m not sure if you have a p-pump 1993 i know were still votary pumps, what brand and part number are you injectors? that's the info i would like to know. I just look at if i met you a the gas station and said hey nice truck, what did you do to it? would you tell me to go search cummins forums.....

I would also be interested to hear from some of the guys and gals who have made those numbers, but VERIFIED. We can guess till the cows come home, but I'd like to know some factual info. I am trying to build mine to make 4 digit torque numbers safely and reliably. If you have built a rig in this category I'd like to know the specifics of what was put into it and what the end result pros and cons were i.e. runs hot, can't keep clutches together, chews up u-joints like popcorn, throttle response is weird, turbo lag is bad, twisted frame...

I have been doing a tremendous amount of reading on here, but I'm still looking for some solid examples of setups that work well. I'm interested in doing it right, not so much on a budget.

what ever happened to a little trial and error. The more y'all work on your truck yourself and try your own unique combination the better and more of an accomplishment it will be. Just because you have money to through at something and not care because you can doesn't mean you should. And personally any JACK@ss can do this. I mean if you build it yourself and break 500hp then you can say hey i did this that's my accomplishment and have some pride in it. There's no pride in just copying someone else hard work just to say Ive got a big bad truck that i know nothing about. But hey i am young and old school do what suits you but think about what you have in the end.

what the crap? that pride would i get from buying the wrong parts and spending more money to make less power? why even have a forum if you just want to try and throw parts at an engine every weekend? Yes, the people on the from lines in the pulling world and race engine builder are awesome we all know that, but for people who need the most for there money they go online for help.Its just too bad that 2 people ED at me for starting to ask a question instead of trying to help. Not all people who want to build an engine once is a JACK@ss. I have build tons of engine from jeeps to Late model race cars, DRag trucks you name it! Ive had 3 12V and 2 24v cummins and i just want to build my dream truck that i wont have to do anything to once its done. Thanks for the help.

Wow, this sucks that no one wants to be helpful at all and just offer up smart@$$ comments...

He's searched, and now he's asking questions based on his search, what the heck is the problem?


nic6556:

Though I can't help you with your HP goal in reality, because I'm not there, I can give you a reference. I could tell you what others who are at that level are running, but I don't know from experience.

I would give JKidd at Diesel Auto Power here on this forum a call, and ask him this question personally, you'll get much further. He offers some of the best deals on the best parts, and he runs and tests them too. He can help you realistically reach your goal.

Responding to this maybe be futile, but I will give it a try.

When I was young and dumb I did a lot of trial and error with minimal research on my Jeep. In the end I put a little over $40k worth of trial and error upgrades which in the end if I did it right the first time would only have cost me half that. My Jeep was a project vehicle not a daily driver so I could afford the down time. I personally wrenched on every part of that rig. If I did a little more research initially I wouldn't feel like so much of a jack@$$ for the excess money I wasted. That Jeep was heavily modified so its a little different than comparing it to my truck upgrades, but the principle is the same.

As far as throwing money at it because you can, that is not whats happening here. In my experience if you cut corners you end up breaking $h!t and end up paying more for a lot of unnecessary down time and fixes that could have been prevented. I have two friends that have had to replace 3 12valves between the two of them because their trial and error cost them. I personally can't afford this. If I was a rich guy who wanted to buy all bolt-ons and have someone install them for me, your right no sense of accomplishment if you want bragging rights, but thats not what I'm looking for personally. I wrench my own $h!t. What I've read is that low 4 figure torque numbers is not that much of an accomplishment compared to what a lot of people have gotten out of these engines. I know I can get those numbers on my own, but it probably would be running too hot and burn up. People come on here to learn from the trial and error of others so they don't make the same mistakes. If there is any fool in here its got to be you. Why would you come to this forum if you are to proud to use the info learned in here, sounds hypocritical. I support nic6556 on this because I personally am searching for a little guidance on how to take all the info I'm learning in here and successfully put it all together to accomplish my goals, because there are more than a few ways to skins this cat.
