94 12v looking for 700hp?

all ya need is enough air to support it, enough fuel to support it and an o ring job and studs

everything else you listed is ginger bread

yeah i figured most of that wouldnt matter, i understand the whole air and fuel aspect of it. Just didnt know at what power leveles, stock internals start to fall apart or wear out. But i would guess they can hold up to alot.
 
most folks that build a modest pulling or drag engine use 12v rods, just sayin
 
recipe for 700+...

1. oh wait, I can't hit that with what I got... :bang guess I better not give any ideas! hahahahah :hehe:

but really, you won't need a benched pump, 5x.016s or something equivalant should be sufficient. you won't need a "built" motor either, with the turbo setups I've run, I've gotten away with stock cam, stock pushrods..etc. but if you're going to do it and get it out of the way...I can't say a cam is gonna help though...I got my pump benched and put a cam in and managed to lose power :)

In the testing I've done, power quickly drops off on 160 pump trucks when fuel pressure drops. None of the electric fuel lift pump setups maintain full pressure when 700 HP worth of fuel is drained from the P-pump so you need to start at 50 psi so it can drop to 40 psi without having a major impact on fueling. I picked up 83 HP in my Junker Drag Truck from increased fuel pressure so trust me, you will need good lift pump pressure to reach 700 HP on a 160 pump.

I have read others' claims that the 215 and 180 pump don't need as much fuel pressure to maintain full fueling. I personally haven't tested power decrease on 180 and 215 pumps with low fuel pressure so I can't comment one way or the other.

I've read that the 160 pumps have a different cam design which has a shorter fill time than the newer (180, 215) pumps.
 
so i have to related questions..
my first one is ive been doing alot of research on this site about delivery valves and what flows the best, and im guessing besides 191's and full cuts, a good flowing combination would be 131 dv's with 181 seat's?

and also, its a manual, i think i have 4:10's? and my gears are really low, im looking for something thats a little taller than what i have, so would 3:55's help out any?
 
one thing i learned that if your almost broke now, you will for sure be in the hole by the time your done. LAMO
 
I don't think thar 131/181 dv combo would be sufficient with 160hp pump to 700+ hp.

i wouldnt think with my 160 and 700+ ponies it would be the most sufficient combo..i was just saying maybe for now to work up to those numbers, to try out differnet dv's to see which would fuel best for my set up when it gets close to that
 
That combo wont make a noticable difference imo. If your going through the hassle of changing the dv's then take it a step further.
 
ive netted myself 616hp/1143tq with 18psi from a fass 150/180 on a benched 160 pump.. there is a ton more fuel left just got to get it burnt
 
so im gonna start ordering a few things here and there soon, an im thinking bout getting the sdx 5x18's with there comp dv's, and order a 4 or 5k gsk from puredieselpower. is a 5k to much, whether i see that or not? I wish i could find the thread i was reading on somewhere around here, but this guy was saying a 5k is more streetable, maybe not more streetable but smoother than a 4k to drive with?
 
If you start by sending the pump in and haveing them get the most out of it they can on the bench, it makes everything else so much easier.

i wouldnt doubt that it makes it much easier. On average how much does benching a pump cost, ive only asked one place since ive owned the truck but never got a reply back on the price.

I think I'm taking your advise on this one Ron. What's the going rate for getting the most out of a 12mm pump? (CA 180 if it matters)
