mmmm, I'll keep my eye on this thread. What EGT'S are you running??maybe PM dieseltech for an opion(andy)
certainly is,I reckon I've read of a mod where the existing 10mm plunger is replaced by a 12mm version. I'm not sure of the cost or the availabillity, but if you do a search for posts by OldMav about power, or pumps - you might find what you need.
Think you better send your car or pump to Andy and let him set it up for you. The compensator has lots of functions and it all ties in with max fuel/boost pressure/turbo spool rate etc.That graph is interesting as its essentially what I'm getting. Your GU, Truckster, I'm assuming? Was that the limit of the Injector Pump?
My injector pump is indeed the 11mm and i have verified with the serial number pressed on the side.
Andy when you say the Compensator is modified in what way? Can the compensator be used to regulate full at zero thottle? It appears that the boost compensator doesnt come into play until approx 3/4 throttle movement.
To increase fuel coming out of my pump, short of 12mm plunger, i need to limit the fuel at zero throttle.
I'm starting to think ive reached the limitations of the stock injector pump
And that isn't what i said in my post???????I'd have to disagree with you matt to my understanding the compensator is a rather simple piece of gear. Just a progressive valve controlled by pressure, be that from forced induction or atmospheric. You have control on when it starts to operate and its initial position which in turn affects the amount of fuel injected thereby altering things such as Turbo spool rates.
I totally understand mate,and i appluad you for having a go.But if we gave every tom dick and harry all the information and secrets to make power ,then there is no point being in business. I made the same mistake years back and was told in no uncertain terms to go and find out yourself, so i did and now i have a very good knowledge and understanding and can put together some serious power packages.Sorry Matt i value that you did make a contribution to the thread. It just frustrates me when people say just take it to a specialist when i can give it a go myself, with a little guidance. So i guess i was just showing you that i do have a fair idea on whats going on. There's specialists out there half the time because people dont take the time to understand how things work. Not to take anything away from what these diesel guys out there do, especially when they're doing modifications like 12mm plungers they really come into their own.
114rwkw on 33' muddys with a IP that has been completely setup by myself i think that's not to bad. I was just trying to see if i could extract some more hp for jam.
Well that's my little rant i guess. I suppose ill just have to accept that without some serious pump mods the big rig isn't going to be a Formula 1 racer.
This is the only hobby/tech scene that I have ever been involved with that information is so secretive. Yes, people have business interests linked to specific setups but then again what proportion of people that are actually looking to modify at home were going to take it to a diesel technician anyway? Seems like the only reason that it is this way is cause not many people play with Nissan diesels compared to their petrol brothers so the number of people willing to share information is just not there. Is it not a partol4x4 forums rule that promotion of business is not allowed in this section, why are any businesses even being plugged here? All I see is an ad for Diesel-Tech so far with vague assertions that they know what they are on about. If you have a recipe share it, if enough like minded people also try it and give input/feedback, the results will improve..oh wait..that's other forums...
I think so, he has about 4 of them on the shelf in the office... :lol: :lol: :lol: :lol: :lol: :lol:As for Andy, do you know what a disco potato is?? .
I am with IS400X,
And I will add Madrolla if you can’t answer the question then don't. You obviously can't so don't fluff it.
As for Andy, do you know what a disco potato is?? I spoke with you personally on the phone and I asked if you use disco potato and you questioned me what is that, disco potato???
No disrespect meant here (I think) but answer with fact and not PULP FICTION.
