How to make 700hp VP44?

see that what i think also
in diesel power a guy with a monster and silver bullet and spary did over 1000hp so the fuel is there you just got to get it burned but on fuel only to get big #s you would need some very good tuning

I don't know a lot about spray... but the way i see it, it isn't the VP holding you up if ya can spray it and make over 700...the fuel is their... it's the lack of air. But i very well could be wrong!

Thats what I always thought.
 
I think it is difficult/impossible to get the same burn efficiency with plain air and big turbos vs nitrous assisted air/ big turbo(s).
 
It takes about the perfect tuning and the right setup to make 700hp on a VP! And it proably wont be to street able. And more then likely you will see me on a Dyno at scheid, but only if the truck is %100 percent lined out, and im running the setup i want to run. That is and s465 and a shot of water/meth! If i have that i mite get on the dyno. I mite get on a dyno at TS if i have water/meth.

What injection pump were you running when you did this? Also what injectors?



Wow that is really crazy if you ask me! That special must of been ready to blow up, do you know what his egts were during the run by chance?

egts were under 1350 i believe. it was ericks truck that did it last year at the dyno event in hollister. people that dont use nitrous on these diesels truely are missing out on the cooling effect. you always hear people say i am just using nitrous for the cooling effect and well yeah it cools but that is BS. water will cool just as well but when you can have something drop egts and make a bunch of extra power at the same time, then you got something. i guess i am just addicted to :nos:

the problem with the VP setup is air. almost all VP trucks make peak power under 3000 rpms. shoot i will venture out and say 2800. you go with a huge set of twins and in order to make power you have to be spooled up by 2800. well with a RPM limited truck, thats a hard task to do. like mentioned have to have a perfect tune and its acheivable. fuel is there to make 800 on fuel but not air. thats why :nos: works well on a VP truck because it really helps burn the fuel before 3000 rpms.

I would like to try NOS down the road but it seems as if i have heard way to many bad stories on what can happen and thats what makes me kinda iffy on the whole NOS thing...

what have you heard? hope your not talking about nitrous and gas motors. 2 different animals. nitrous on a diesel is a good thing .
 
the start to my build. but as inline6power says its the lack of top end. I dont know if i should bother with fighting w/ the vp for 4000rpm or just p pump it.

where do you plan on needing 4k rpm? are you building to pull sleds?
 
Traction for drag racing or sled pulling? You really didnt give an answer? What turbo are you running?

NOS in diesels. I have heard of a lot of nitrous backfires, blown turbos, switches getting stuck on. Just seems like there are many things to go wrong and hurt the engine, but granted i don't really know enough about NOS to know the pro's and con's of it. I know there is a lot of power to be made with and im interested in it just wanna make sure im not gonna ruin my engine in doing so. So please enlighten me! :woohoo:

backfires come from people trying to spray to soon or spraying then letting off the gas a quick second then getting back into it. blown turbos come from LOTS of nitrous but if you are after BIG hp thats the risks you take to get there. its so so simple to setup with hobbs switches. their are cons like mentioned above but i think the pros are bigger with the huge cooling effect as well as big power gains. it really all depends on what you are going to do with the truck and what you want to do with the truck. granted when you are trying to make HUGE power, nitrous tunning becomes a lot more critical but for street use and just a little to play with aint nothing.
