:hihi: Agreed. So after pulling the new pump again tonight I put the old one back on, the screw is pretty tight, so it is pretty much maxed out. I tightened up the gov spring like you said 6.2 and it worked, in fact the idle was almost too low to run the truck, but I just adjusted it up with...

Sounds like a good plan, I am anxious to see.

Agreed turbonator. I think an 831 pump is just a little shy to break the 300 rwhp mark. I am guessing my 839 pump would support 400 hp at the crank (If I can ever get it running!) but that would only be with the right supporting mods, some of which I do not have yet. I think my turbo could get...

I want videos too :)

I would be interested too in a dyno run like that. I have heard a turned up db2831 pump (stock) won't do 300 hp at the wheels, which makes sense, thats like 150 hp over stock. I would be impressed if it could do 300 at the crank. With mine maxed out I was not overly impressed, but I believe my...

Well I didn't check with any sort of measurement but they felt like they were as tight as the originals in their bores. I hadn't thought of the plungers being in wrong, but I think he put the same radiius on each end so they were uniform. It could possibly have been the delivery valve, I will...

Well 6.2 turbo, I gave it another go today with no luck. I tightened up the governor spring and put it in the new pump. When I had the pump in, I blew air into into the inlet at the back of the pump (about 80 psi but I couldn't get a good seal). I then cranked and cranked and she wouldn't fire...

Oh and one more thing I would add. I agree with what everyone has said, I take the inner fender out as well, mostly because I have had that thing off more times than I can count. Just to warn you, you may break a couple of the fender nuts, depending on the rust and how long it has been since...

Very nice Joey, I thought it was respectable, and as long as you had fun thats all that counts :) My standard never seems fast when I see these videos. I like your Dana 60. If I had the money I would go that route but I think I am going to do a D44 from an 80s chevy and the NP208 transfer case...

Oh ok I see. When I put the different main spring in, I tried to match the distance between the head of the bolt and the piece that it threads into that contacts the throttle shaft so it was the same as stock. I will give that a try. The idea of this thing running away scares the crap outta me...

Ha yeah we grew up together in a small town, he is about a 1/4 mile from my house. We bought are trucks from the same guy too ha. You are right about the DP mag site, they don't have the newest articles up yet from the most recent issue.

Very interesting! I am anxious to see how it does for temps, there is only one way to find out if things are gonna work and thats to try it :)

Sounds like you guys have quite the list of things to do! That's exactly what I did with the pump, I loosened the lock nut and turned the shaft out, enough that I thought it would make a difference but it didn't seem to help, it may have dropped the rpm by 50-100, but its still hovering in...

Well guys I didn't get any chance to work on the pump over the weekend, I instead spent Saturday cleaning up the absolute mess I had left in the shop at home :) I also reorganized my tools, finally put that little tin cover on the bellhousing, and I attempted to adjust the idle, which was a big...

No you are right dave I looked too, it says October 2011 readers rides but that is last issues, but i can't remember what last issue's month was, because its never the month you're in :???:

Ha yeah that is Korys truck and from what I am told, mine is right beside his in there LOL, I don't know yet. He got the VGT idea from ME :) which I got from turbonator and Don :D

Oh ok. When I talked to Gary over at Davies he mentioned running into some type of cavity when he did your plungers, that must have been it. He told me he did not run into the same problem with mine, so you could be right with the plungers being stuck, I didn't realize they could do that ha...

Haha yeah I know what you mean about the free test stand, I at least want to be a bit more sure the truck will at least start on the new pump and get me from A to B before I go through putting it in. I will check what some of you guys have said when I get the chance. When you said about the...

I might take a look at the pump this weekend. Would an injection shop be able to test the pump on a stand? (without charging me an arm and a leg). What pump are you running on the Tahoe? the DB4? Is the 52 wastegated? Is this the pro 52 or the Volvo 52?

No I did not check that, when you say centering hole in the drive slot, are you referring to where the rotor meshes with the drive shaft inside the pump? Also I never thought that the plungers could stick, but that is a good point, when I put the pump together I used clean diesel to put things...
