EDM'ing is pretty damn precise... According to NMB2, his injectors flow plenty, and I have no reason to doubt that. I think if we reached the point of not being able to deliver the fuel the pump can with the injectors, EDM'ing would be the next step for that. All I know is that MY stg 1's have done me very well, there is none of the symptoms that have been complained about in the past, and I knock down 16-18mpg's avg with 4.10's... Pretty hard to beat, with ANY injector.
Anyway, my 60 and lift are done, so now I can get to working this pump... Ill get some plungers done soon...

What hardness did you figure out the rotor to be? I think you mentioned it earlier in the thread, but can't find it now.
What/how were you going to do to make plungers? What material are you shooting for on those? I haven't seen what the actual plungers look like, but it might be possible to buy off the shelf hardened stock to use then starting with soft material and going through all the steps.
BTW, if they wire cut the holes for the plungers, I hope they did a small arc into and out of the 'cut' or chances are there will be a small line at the start/finish point that will be a lot deeper than the actual wall/side of the hole.

For the fill holes, they just used the hole machine and "drilled" them. For the plunger bore, they wire cut it, and they made sure to let me know about the line. Im going to do the finish work myself, so thats no worry. As far as the plungers go, im just going to use some O-1 drill rod and make a couple, its cheap, and I can play around with it to get the finish size I need after HT...

For the plungers you could pick up some drill blanks, should be something pretty close in size to what you need.
Actually in a properly setup shop that is an easy hole to hone.
I think our hone would go down to about 1/8". The issue becomes there are more arbours etc that are needed because they cover such a small diameter range.
The small ones are when they get to be a millimetre (0.040") in diameter and under. We had a different way to deal with those though.

Dropped the rotor off at a grinding shop to get honed to a 10Ra finish... That on its own should be sufficient for the plunger bore finish but I might even polish it after that, well see how it comes out. As soon as I get it back, Im going to start on the plungers.
So with that being the case...
Anybody wanna place bets on how long this thing will last???
... I already have 5 minutes from a well known pump builder, and the local shop wont even touch the thing LOL... Either way this thing will be ran until it ******s... And hopefully the little details will pay off...
With that being said... The local shop mentioned to me that they built a 120'ish cc DB2 with a 6.2 gov spring... Only thing they changed was the leaf spring and dialed it in on the stand. The pump guy is interested in building me another one and I have a spare pump I might let him rip into provided the pricing isnt too outrageous... Thats something out to the side and I will update on that the more I know, dont wanna distract from my pump build.
More soon...

i think it will be fine until you snap the throttle or it will last a good while. that initial crank will tell a lot.
do you plan on doing a pressure check/leak down on the bench? assuming that you can.
going to shoot a video of the first crank? :P i wana see what she will do

after talking to Ken today.... Justin and I are both left thinking.... "what the **** Ken...."
I'll let Justin elaborate a bit more on it if he wants to, but lets say I feel insignificant now....

I used to own a idi and still have a na motor for parts for a buddys idi. I am very interested in this pump i always prayed maybe somebody would have the ********* to go in head first on one. This being said i now own a 12v and our stock timing is 12.5* majority of the stock trucks some with bigger pumps may run 1-2* higher. Normally we dont advance it past 16-18* because of cold start issues. And i was looking at the rods i have for this idi today and have a possible way to make stronger rods. Why dont we just do with idi rods what cummins guys do with there stock rods to make them good to 1000hp. First treat them to a full polish job no burs or casting ridges left. Then have them shot peened should ensure they wont be your problem. And could also balance them to. As for the hg possibly acting up you could have the head and block re taped for some larger possibly 14mm headbolts just torqued to spec may help. That is also what a few of the cummins guys do running twins and signifigant boost. Notice these are just some thoughts of mine just my .02.

The rod idea is good but the problem with your head stud idea is that there is not enough meat on the block. Also the problem with nitrous is that we hardly have enough fuel to begin with for a turbo to burn let alone with nitrous too. I guess it would clean up the excess smoke though. I have seen that a guy with a NA idi does run nitrous but haven't seen any videos or any numbers...

Nos would work good for NA i think, but i wonder about EGT's.
If 13mm, 14mm, or 9/16's studs could be made to work, i think there would be a mess of people stickin em in 6.9s.
Polished / peened rods have been my plan from the get go, along with some cryo. I dont think rod strength is the issues so much as wrist pins, which is the only reason i was really lookin for rods. No luck thus far, so going to try out the silvolites.
Back on topic...You feel insignifigant? Funny, i always figured you held yourself in grand esteem lol
