ok then, BACK TO THE 1200hp IDI

[88beast]

freebird as a few know im working on a compound turbo setup lower cr over 30 lbs boost studded and some shiny gaskets custom intake and exhaust manifolds
large oil supply to the turbos
intercooler
water ****
tons of portingn work
and some more goodies
i think ill use a moose up easy and a supermoose well me and mel talked and he knows my reasons ill leave it at that
but still with all that if a moose is enough then we dont need anything more but if a gm needs more fuel for that and its smaller with the same pump id assume we will too

Well, you are already on the right track. I watched a program the other night on PBS about what separates us from the primates. The biggest difference between us humans and the primates is our ability not only to learn, but to teach each other as well.

When guys come on here and say they are going to (or have done) all this black voodoo on their truck, and refuse to talk about it, or explain what they've done, we all get apprehensive right out of the gate. There really is no reason to be secreative about what we do. That's the nature of this forum, to promote the exchange of ideas and knowledge! We had good reason to hide our development of the atomic bomb from the Germans!

I'm secretly hoping that one of these days some old-timer engineer from International will get on here and say "Hey, I'm the guy that designed these engines, what do you want to know 'bout them" but I don't think that will happen, he's either off enjoying his retirement or bound by non-disclosure agreements... oh well!

or dead...engineers in auto companys tend to stick around for awhile lol. could have been some old geezer back in '80 or '81 that was working on it...

Dual pumps is a great idea! My only concern would be would they work against each other? Should effectively double fuel output. Two stock pumps would push around 140cc's. Two moose pumps 180cc's and two supers at 240cc's

Custom mount, custom intake manifold, custom lines, and figure out how to turn them and your set.

 

[DeepRoots]

psd valve springs fit i tested that

did you actually run them tho? in matters of coil binding and the like, just installing them is not good enough (especially with hydraulic lifters like we have).

good luck,
Drew

i guess my question is why go to the trouble of modifying a P-pump to fit our engine when no one has been able to use all the fuel that a moose or the "super moose" will put out (which are bolt on modified DB2's)

and no im not trying to start a ******* match. its an honest question.

and tom...man you really need to work on your punctuation and sentence structure. your posts are almost painful to read lol

Honestly, I have room for more fuel. My EGT's are never an issue. Most I see is 850 max. Now the turbo is another matter. The Banks is at it's design limit with the fuel the Moose IP/Injectors provide. Personally, I don't want to do anything else with my F250 IDI. I like it where it is. The crew cab, however, could use Moose fuel to help with towing the camper, and I will add that later on.

But, in keeping with the OP's thread. Big numbers are easier to achieve with a different IP. The DB2 can only put out so much fuel and do it with any reliablilty. That's why the P-pump conversion was being discussed (dreamed).

my question was with the OP topic. im not trying to be argumentative just tryin to learn something like the rest of you. I have largely ignored most of these type of threads about theory because i didnt care. my truck runs and pulls my camper (not sayin much i know) and my car trailer.

but with anything now im lookin at things a bit more since i plan on starting a tear down of my truck after the beginning of august to do some body work...and if any motor work should be needed that would be the time to do it as i want to do a front clip swap.

thanks for the response heath. thats more what i was lookin for.


what inline p-pump are we talkin about exactly here (as in model#/specs)??

 

[BioFarmer93]

i agree.
but I also have a responsibility to keep the peace around here too. this nonsense with NMB2 and his minions have gone on long enough and I'm getting complaints. therefore, something has to be done.

MINIONS!? Towcat used minions in a sentence, spelled it properly AND used it in the correct context! I'll just be damned..... Brad- call Hell and see if it froze over again, please.

 

[snicklas]

Minions - those are the little yellow guys in Despicable Me.......

 

[sassyrel]

When you compare IDI to DI engines, the DI engines have a domed piston to evenly distribute the combustion force over the face of the piston.

ever had a power apart????

 

[sassyrel]

much more efficient

i hope that made sense to yall cause i just woke up[/QUOTE]

as one said a few days ago,,you have good posts..but no use of periods,commas,,or anything else,,to break your thoughts...makes for near impossible reading.....

 

[wmoguy]

why not multiple injectors per cylinder? They are doing those on Cummins sled pullers and dyno queens now days.

FWIW, I know the Cummins guys are often more focused on drive pressures than over all boost. They are probably onto something there. Within some level of reason, equalized drive pressures could probably relate to allowing higher boost #'s on our IDI's before head gaskets and lifting heads are an issue.

 

[FordGuy100]

Well you are shooting for as close to a 1:1 drive pressure/boost but that is not going to happen. I'm sure a stock hypermax, banks, or ATS has a very high drive pressure at 10+psi

I can think of one reason...as I understand it, the inline P-pumps are considerably more reliable than the "standard" DB2's. I don't follow the Cummins as closely as I used to (when I was younger, I desperately wanted a 12 valve Cummins), but as I understand it, P-pump failures were FAR more rare than standard DB2's. I know also that the Bosch inline pumps used in the M-B diesels are pretty bulletproof...having one fail is a very rare occurrence, contrasted with the understanding that DB2 failures are almost routine.

I'm still curious to see how the Moose Pump lasts over a long time (i.e. 150K+ miles) and plan to use a Moose Pump for my next IP to test exactly that, but I've always contended that IH made a mistake using Stanadyne fuel system components instead of going with Bosch. As I understand it, it was a cost-savings measure at the time, but IMHO it would have been better to spend the extra $$ in the beginning and have fewer replacements in the long run. If it were cost-effective, I'd be very interested in swapping over to a Bosch fuel system.

I should qualify my statement...while I think anyone's looking for a bit of extra power and I'm no exception, I'm most interested in reliability, and I'm willing to sacrifice some power in the name of efficiency (although IMHO many modifications that add power also increase your efficiency when the power isn't being used)...

Just my $.02...

 

[Sw1tchfoot]

The idi would probably make decent power as-is if people would put together their own exhaust and turbo setups rather than using bolt on kits.

But then again there isn't as much room with a V8.
