if you read to book i posted in the faq zone by chapter 3: selecting a turbocharger you see how un-easy it is

Sometimes. An engine with flow capiblities greater than 300cfm (roughly 180cid) can benefit from two turbos. two little turbos can slightly cut turbo lag, as opposed to one large turbo, and allow a better balance of low-speed and top-end boost perfeomance. Over 350cid, twin turbos become a virtual necessity. do not accept the idea that twin tubos are inherently more powerfull, as too many other factors are involved.

single - vnt - bi - twin, i dont know it, i'm going for vnt right now, but its not the idea from the expert

my post realy dont make sense, isnt?

A VNT from a truck would be way too big. Look for a VNT 15, most commonly  found on VW PD 100s.

Hello all, again!

Well over May long I played with the IP, trying to get the Gov. mod
What I am finding is that at up to half throttle it returns to idle fine, a little slow, but not to bad. as soon as you floor it, it stays there.
Now jimfoo, mentioned turning my residual fuel screw up a bit. Unfortunately when I look at a post that showed this screw, it looked to me to be the screw that adjusted the position of the accelerator pedals idle position. IMO that will have nothing to do with the increase in idle at the higher RPMs.

Actually, I said I had to unscrew mine a little, and yes, that is the screw. Does the throttle lever stick any?

Perhaps I am having a long day, or the pollen is giving me a headache.
Anyway here goes,  I am always interested in reading other peoples posts.  There is a lot I dont know, I will be the first to admit it.  Perhaps you have a much greater diesel or mechanical base of information than I do.  It kind of irks me to read about how you are tired of reading dead end post, or posts that don't get updated.  "Just find me the answer and post the link"-paraphrase.  Some of those posts may be mine.  I apoligize if some have dead ended or have not been updated.  I am busy with raising 3 small kids and working a hectic full time job.  I log on here because it is fun and I like talking with the people here.  As a value added benefit, there is a HUGE wealth of information in past posts, and in the people who use this site.  If you want to run way big boost, I think that kicks ass, really.  I did too.  I spent months searching old posts and asking questions from people here.  Who has done this, what kind of set-up did you use, etc.  I pretty much learned that big boost costs big money and comes with big problems.  None of this appears easy to me.  If you think Andy2's twin turbo setup is easy, I again think that is great.  I look forward to reading your posts on the subject.  I will read them with the same intent as I do others, to gain some knowledge, see if it is feasable and to daydream a bit about what I think is cool. Perhaps you can contact him and see if might be able to offer some help with his HG problem?  
Knowledge  after all is meant to be shared.  On the flip side there is always knowledge to be gained.  Neither of us would be posting here if we did not have similar interests.   I think it is great people here have figured out through lots of trial and error, time, money, and years of posting and wrench turning how to make diesels finally kick ass.
I guess some of the posts just struck me the wrong way,  If I am out of line, I apologize.
Jim

Sorry if I ticked you off. I guess my iritation comes from days of reading and in the end finding out nothing at all. I do have no problem searching the posts. But I have always been of the opinion that if some one else has the knowledge, or knows where to look why spend weeks wasting my time. I am more then willing to post a link or point someone in the right direction if i know it.
I didn't mean to say "Find me the answer and post the link" I ment if you know the post that has an answer, ie you just finished reading it, got it favorited etc, then please post it. As i am sure you don't like running in circles too.
I also appreciate the fact that tons of people have spent tons of time and money and fille this form with tons of information. As agian like you I unfortunalty don't have the time or the resorces to to this. Starting a family and tring to get a house ready for it, along with a job take a lot of your time! So I appreciate everyones postion on this.
And I finaly stole some time and skimed through Andy2's post on his problems. So I will try to keep my self updated on it.

I also am trying to be diligent and updating my initial post on what knowledge i have gained and answering my own questions, sometimes i fail to update...
I guess some of my problem is I don't have a ton of mech experiance to draw on or and knowledge on where to start looking. mind you I try!

I guess I am sorry to all that have read thinking that is what i want. It isn't I just want some help, a freindly point in the right direction, but please don't think I am sitting here waiting for you guys to post all the answers, and not looking my self.

I just love to work with this stuff, wish I would have taken it instead of the schooling I did take. But that is another story! I was just looking for some help. I am sorry if I offened you. and any one else.

About Andy2's problem it is deffinetly very discuraging to my daydream! As I read in a few posts that the 1.9 HG would hold out at that kind of presure. Maybe no one tried it, and Andy2 finally tested it.

Oh well i look forward to reading some more, and figuring out what I can do with my car!

Jimfoo,
No not at all, that is what is getting me. This aft, i sat down with a coworker, and we talked about it. I am thinking a Stiffer spring instead of shiming might help, or a spring between the case that holds the gov. and intermediat spring might help. as you let off the throttle it would force the fueling lever (not tech term) back to the idle possition. It is a confusing problem to say the least.

I think I need to get more info. on the workings of the IP. I am still looking for a manual for it. I seen a few links but didn't have time to look, plus I have no idea what model my pump is.

when i get to where my server is i will post the pics.

If it came off a vw 1.6td it should be a bosch VE.  You can take the number off it, it usually starts with 0 460 xxx xxx

This link will tell you how to decifer

Subsonic,
Thanks, read that post a while ago. have to figure out where that ID plate is.

I have found a Turbo of a Mercede Benz 270 CDi, and am not sure if it is a VNT, the page doesn't say if it is or isn't. I know it has a .45 A/R, it isn't a bad price.
I am thinking that, from what I have read (that I remember), a higher number might be better, like .5-.6 ish area. Am I right?

Also I have turned my pump up, and adjusted the idle, throttle position, etc. to get the most movement, and most fueling out of it. But it seems to be useing more diesel then it should, IMO.

I guess what I should be asking is, should I be looking at refreshing this motor? +300 000km all original except a Trubo rebuild. Just thinking that maybe this might be my problem...

Sorry no Pics yet, haven't made it to where my server is...to much on the go.

Pictures of the Pump are in!
Here are pictures of my pump and me modding. I am getting a run away revving problem at high RPMs.

I hope some one has some tips, or hints on what i did wrong if anything, and what i can try to make it work.
