Lets talk performance fuel injection....

[Agnem]

Here is my "add".

The guys assesment is correct. My program takes your existing pump and we do a complete rebuild on it to my Moose Pump specs. All work is performed by an authorized (and very competent) stanadyne shop. As was mentioned, there is no set price since the work is time + materials + calibration + $50. I can tell you that in addition to my own truck, I've sold 2 so far, have a 3rd customer being serviced right now, and prices have ranged from $500 to $700. If you want a quality product with guaranteed service, then that is what I offer. I don't offer a set price or an exchange program at this point. I hope to work up to that, but I'll need to get a good bit more volume going before I can recoup my R&D costs or actually make money doing this. Right now, it's just a service to the community. PM me for more details if your interested.

so only one person sells performance injectors? i'd like a set, but that if there's iffy opinions about him i'd rather stay away, i have no problem going with a moose pump, and as soon as the money is saved i will, everything i've read about it has been good. i'm sure stock injectors will be fine if there's no aftermarket upgraded ones....any recommendations on "best" injectors then?

thanks,

At this point, there really isn't an upgraded injector available for the IDI's. The set that I had from Ken at DPS just had the pintle's ground off and the tips drilled out to make a bigger passage for the fuel to flow through. The problem was, the precise size of the hole on the tip, and the pintle is what makes the fuel atomize and allows for a complete burn. The upgraded "Moose Pump" and a brand new set of Delphi injectors is where I'd start if I had it to do over again. I'm still a little iffy running a DPS pump in my truck, but so far it hasn't posed any problems. I can't tell you if DPS does anything special to the pump, but my truck seems to run pretty well, with the combo of the DPS pump and brand new Delphi Injectors.

Knowing what little I know about Mel or the Moose pump, I'd be WAY More confident in that product than just about anything else on the market.

Thanks for the vote of confidence. The situation with the injectors is just what you said. And I am not confident that the DPS ones that I have on the Moose Truck are doing anything more than creating more smoke due to lousy atomization. The stats Barney posted about his Moose Pump run were with stock injectors, and I'm thinking better atomization is really a key factor in burning more fuel.

 

[reklund]

I'm thinking better atomization is really a key factor in burning more fuel.

You're absolutely correct Mel. There's no good way to burn all the fuel a DPS injector puts out in a street-driven truck. All that fuel is fine for a sled pulling truck where fuel economy and smoke doesn't matter, but doesn't do anything for the rest of us.

I'm not sure what we're going to do to get more fuel out of the injectors AND atomize it so it's useable. Also, I'm not sure we can stuff enough air into an old IDI engine to burn all that fuel and not blow the heads off the block. As my truck sits, I get about 9 psi of boost on a good cool day, at the manifold. Granted, my numbers will be a little lower due to the pressure drop of my intercooler setup, but that's about all I can run with my non-wastegated ATS setup. Even if I had a wastegated Banks or Hypermax setup, 12 psi is about all these engines will take. I'd bet a good pump and stock injectors provide enough fuel for 12psi to still get some smoke out the tailpipe and/or melt things down due to excessive EGT's.

I'd really like to hear what kind of EGT's and boost levels the Moose Pump provides. Also, how bad is the smoke? I know we all like to roll the coal out the tailpipe, but that's just wasted potential...

well that's fine, i'll go with regular ones, my mind is setting on the "diesel power mag" with every other page advertising power stroke performance injectors, i think i have to find injectors to make more power. hearing that all DPS does is make it dump i'll stay away. where can i get delphi injectors? just order them for a '86 6.9??

Thanks,

I think what you want is to order the BB Delphi injectors. Mel might know the best source local to you since you are in PA. If you want to go mail order, you can shop ebay, you can try and buy them from Central Motive Power in Albuqureque NM, or Diesel Specialists in Altamonte Springs here in Florida. You shouldn't have to be paying more than about $28 each for the Delphis + shipping if you buy online. If you buy a Moose Pump you'll be in good shape...if not you'll want a 7.3 stock pump such as a 4812 to match those injectors.

 

[Agnem]

I can definitely supply quality stock injectors if that is something folks are interested in. As for EGT's and boost, I think it is pretty safe to say that we don't have a truck capable of taking all the boost these pumps make. I know the Moose Truck isn't, and I don't think Barney's setup is a fair test since he has two turbos and most folks don't. I'll let the next guy who wants to blow his heads off figure that out for us. Since EGT's are a function of rpm and boost, there is no real way to say what max EGT's will be since we can't handle the max boost. I'd say the answer is "more of both than what you can deal with". I know on the Moose Truck I need an intercooler for sure, to be able to keep my foot in it for more power. That's my next project.

ok, since we're on the subject, i been thinkin' bout turning the pump up a little more on my '76. i turned the screw a quarter turn when i installed the turbo like banks recomends, but i'd like to try to get a little more out of it. just wanted to get a second opinion before i do. egts run between 550and 600 cruising at 70. i havent been able to get it over 900, and that was under heavy acceleration going 75 up a 6% grade. good boost pressure, 6-7 pounds revving it in the driveway, 7-9 cruising down the highway, and 10+ when i smash it to the floor. the truck runs pretty good, but i wouldn't mind having a little more power available. whatcha think?

 

[Agnem]

Most folks that want to drive by the pyro, just screw it in all the way and back off a hair. Where is your probe located? Your temps sound a little cool.

 

[haywire]

probe's right before the turbo on the cast inlet pipe.

 

[Agnem]

Yea that is pretty far away. I forget what the recommended max is there. 900 maybe?

 

[haywire]

1150 is what banks sez.

 

[mejonz]

1150 sounds like what you should see from the pyro mounted in the exaust manifold .the closer it is to the exaust valve the more accurate reading you will receive.I may be wrong but i believe the pistons start to destroy themselves at about 1250

 

[Diesel JD]

Well, Banks does say 1150 at their location...don'y know that I'd want to go that high. My ATS is located in the same location, and they recommend max of 1050. I heard that the recommendation for 900 as a maximum was for any probe mounted after the turbo. The turbo will usually cool the EGTs down 300*F or so, so you need to reduce max safe EGT by that value for a post turbo. As far as the stock location for ATS I don't really know if those values are too high or safe. They are some distance from the exhaust manifold though. The highest EGT I have seen is 710*F so I know I probably still have room to play.
