Governor Speed too low?

[xantusak]

What RPM can you guys pull your engine up to?
I just recently got a new pump from Diesel Care and Performance and it seems like it doesn't want to rev how it used to. I wonder if they didn't adjust the governor correctly(this is actually a second pump from them, had to send the first one back as it didn't govern the idle correctly-so that makes me question their work all together...) Anyway the engine seems to taper off at around 2700rpm and practically flat and unmotivated to go any further at 3000. Isn't this like 300 rpm early? This will be a nuisence hauling something something heavy uphill, this is an 86 with 4 speed (3.55 rear) and the gears don't overlap so well. I actually made a turbo setup for this thing just for the purpose of being able to rev this thing high without it smoking like crazy so i can actually shift comfortably in next gear. I was at 10 psi when it hit the wall before 3000rpm, ran relatively strong through the midrange(I didn't increase the fueling yet). Is there a relatively easy way of adjusting the governor? I really don't feel like pulling this pump out again to ship it back to these people

mine will peg 3750-3800 all day long and its factory, mine pulls strong up until about 3500 then it starts de fueling and loosing power by the time i hit 3750-3800

They probably sent you an IH spec pump. IH governed their pumps lower but the fueling curve was somewhat different. I ran an IH pump for a couple months. It would hit the best power band around 40 mph whereas the Ford spec pumps would around 50, and it would limit out at 71mph whereas I could get up to 82 with the Ford pump. These numbers were with a C6 and 4.10s. It's unfortunate but Diesel Care has earned themselves a spot in OB's hall of shame. I'd just run that pump till it blows then get a Moose pump or a custom built hot pump at your local injection shop.

Yikes
Are you suggesting the pump will not last too long?? And it is not possible to change the governor setting?? I don't really care for a "hot" pump, do not intend to rip the sh** out of the engine, just wannted to make it run a bit stronger without smoking and deal better with hills....

 

[Diesel JD]

It's hard to say, you're kinda committed with the diesel care pump now unless it is or becomes defective, of course armed with your knowledge that the governor setting is incorrect you could ask for a refund saying that the pump is for the incorrect application. They may tell you to pound sand as well. If it runs well it probably will continue to run well for awhile anyway, I know at least some folks got decent stuff from Diesel Care. "Hot" pumps won't tear up your engine if you carefully monitor boost and EGTs, the nice thing about these IDI engines and if we're to be fair the 12V Cummins as well is that its your right foot that controls fuel delivery and just cause your pump has the ability to black out 3 lanes of traffic doesn't mean you have to do that if you drive it easy. That said if you have stock headbolts and no intercooler you probably don't want to boost more than 10psi very often if at all. Stock bolts and gaskets tend to pop around 12 psi on the 6.9 and 15 on the 7.3. The smart turbo guys on here say that any boost beyond 13 psi gets super heated and is a waste and unneeded strain on the engine unless you do something about cooling down the charge air(IC or water injection). I'd be curious what kind of turbo system you have...did you say you designed it yourself?

You have been victomized by diesel careless. They sell craptacular junk and many have found this out the hard way. The best pump is the Moose pump, then the Moose jr.... Pensacola Diesel sells a good pump for $295.00 no core and no shipping or handleing charge. I have run one of those for a long time. A member here has had nothing but trouble with them too. Thats not the norm though. Midwest diesel is another great pump shop. Read all about the Hall of Shame above. Its there to help others avoid being crapped on by creepy sellers out there selling crap.

 

[Diesel JD]

Yeah but it still probably doesn't justify tearing that pump off. Money is too tight these days or any day... just have in the back of your mind that you should replace that pump someday if you plan to keep the truck for long, and then spend the money either here with Mel or at a local shop that is trustworthy. I too have been down the road to nowhere of economy IP rebuilds. I will not name the seller, not here, maybe not even in private, because I don't think he was dishonest, probably just not very good at building pumps. The first pump sheared a shaft, it might have been because I didn't torque the bolts right nor did I loctite them, it also might have been a bad pump and a disaster waiting to happen. I admitted my mistake and we shared the pain, next pump he sent me had a heat sink problem, and so did the 3rd. The 4th one was pretty decent and lasted 30,000 miles +- including my learning curve with homebrew biodiesel and some fuel cocktail experimentation. It failed pretty spectacularly by dumping fuel into the crankcase. Was that my fault for running unapproved fuels? Or his for possibly using cheap shaft seals? I still don't have a clue. Bad thing is I was out more than 700 bucks by going cheap $200 pump and core instead of just spending 300-500 at a local reputable dealer. I always tell people to support the folks who are making good stuff here or to find a local pump guy who'll work with them for "hot" pumps or for a stock rebuild your local stanadyne shop. At least if you have a problem you know who to call and your truck won't be down for days waiting for a part from across the country. My 2 bits.

they sold you a bus pump. The bus pumps are governed down to 2700, and chances are they don't know the difference. check the hall of shame.
I got a pump and rebuild injectors from them. the injectors lasted less than 5000 miles, my pump is on borrowed time. Send it back and demand a pump for your truck if you can't get your money back first.

Diesel care doesn't have a good reputation here nor they seem to care (he he) You might want to contact Mel Agne to get a good quality rebuild IP. They only thing tempting about DC is they prices not so much their parts.

Yeah I am planning to set the wastegate to max out at 8 psi. I had the wastegate unhooked because I was having a hard time with its adjustment and wanted to see if i can even get that much. It went up there pretty well. The turbo is a T3/T4, off of ebay, for ridiculously low price, I am sure a china unit... will se how long that stays together. Fabricated all the plumbing myself, the turbo sits in top of the engine behind the manifold "pressure cap".
About the pump,...I do not know of any local shop that does this work...and I am not sure about how much agnem's pump goes for, but certainly cannot be a spare change. This truck is not the center of my life, I equipped it with a dump bed and just occasionally do some work with it around the house. Not something that I want to pour money in....but I would like it to work right when I use it, the loss of a qurter of usable power range is rather unsettling....

So no one can tell me if the governer can be adjusted? Is it fixed, non adjustable?

 

[icanfixall]

Yes... The govener can be adjusted but.... Getting in and doing it correctly is nothing anyone on this site will venture in and do. There is much more going on in these small pumps and calibrating it properly really can't be done "under a shade tree".. Send it back... The bottom line is diesel care screwed you and getting anything done is most unlikely at this point. Sorry for being blunt but dc really can't care less about whats happening to you. You see... They already got what they wanted from you..... The money. And you got what they wanted to get rid of... So what if its not what you wanted... We have seen this kind of transaction happen time and time again. This is why I refer to them as dieselcare less..... I'm still amazed they are still in business on Ebay....

Personally, since the truck is not your pet project or your DD, I would just leave it. The pump will *probably* deliver well enough to get the job done. You see it delivers a lot of grunt at lower RPM than does the Ford pump. To me, I really don't care for the way an IDI sounds and feels at 3000+ rpm so my truck never goes there, so if the governed RPM were 2700-2800 I wouldn't notice the difference. No a moose pump is not going to be cheap, it would be quality but not cheap. If you want to find a local shop check on Stanadyne's website for an authorized dealer. Man I think building your own turbo system was way past cool. It's probably every bit as good if not better than the kits made for the trucks. I'm sure I speak for everyone when I say...we'd love to see pics of it. Personally if you trust your head gaskets I'd set the wastegate for maybe 10-12 psi. I think if they are original you'll be replacing them soon anyway, even without any boost, and if they have been upgraded and done right they should last awhile longer as long as you don't go much over 10-12 psi. Honestly though my ATS 088 never sees 6psi very much and I'm still VERY happy with the upgrade from NA so 8-9 should be fine if you want to play it safe.

 

[oldmisterbill]

Play it safe keep the boost down.Look at the hall of shame-I delt first hand with them when a friend bought a deisel care pump he got it home to MA after stoping there to get it running right -averaged 5 MP / no trailer just an empty truck smokin its way home.The cure for a deisel care pump -"replace it"! Idon't think I've heard of anyone 100% happy with their pumps.

 

[xantusak]

Well, if I manage to attach the pics, go ahead, take a look. It is not pretty, I didn't bother with tig welding, although I could have at work. I just zapped it with a mig, didn't have the time and patience to make it look sweet, it is a crude truck. However, there is not much that could be seen on these pics. Most of the work is behind the engine and lots of the hot stuff wrapped with the fiberglass tape. The exhaust plumbing was a PITA, not much room back there... Works good though, cruising 65 on flat will have 5 psi boost, pushing the pedal further instantly rises the pressure. I wanted a small responsive turbo, no reason for a monster when I do not intend to take the power over say 200hp. I was also contemplating on trim 60 T3 but then went with the T3/T4 because of the availability and low cost, plus the T3 just seemed small(even though the compressor map indicated that it would work) . This thing actualy has a slight boost (2 psi) coasting (no fuel) downhill at 60 mph.

Damn, after reading all these comments about the Diesel Care place I think I will just live with the pump I have then. Aside the low governor speed it seems to run ok. Don't want to chance it and get another one that will not run good at all....This is already a second one and they might just tell me to F*** off at some point. I would hate that to happen when I am in possesion of a completely useless junk, at least this one runs. I also replaced my injectors last year and now i dug back to realize that they were from the same place.....they work fine but judging by other's experiences it will not be forever.....SOB!
