Super hot pre 93

[Archive]

Hey guys WAKE UP!!

Where is everyone? I would like more power out of my 89. Does anyone out there have a super hot pre 93 truck?? Have any of you looked at the Diesel Dynamics website? Or have any of you put in injectors or other mods, maybe a pump mod or should we stop wasting our time and buy an inline pump.

BEEN AWAKE SINCE '92. https://www.turbodieselregister.com/memberimages/r0300341.jpg https://www.turbodieselregister.com/memberimages/r0300343.jpg
I've just installed a set of JRE BIG A** INJECTORS, and am about to replace the '92 pump with a new 30% turned up unit.

Old school,
Does the truck smoke bad? What is boost? Let us know how the new pump goes

Big Don:
Here's a listing of some of the mods. and add-on upgrades:
16cm2 hot end turbo housing, Banks 3 1/2" pipe, JRE straight thru muffler, JRE upgrade injectors, K&N filter, boost and pyro gages, 4" H. D. Skyjacker springs, shocks, drag link, and stabilizer. Borgeson steering shaft, 305 85R16 Denman Coyote tires on 3000lb. alum. wheels. The truck is a 5spd. 4wd. , with 3. 54 gears.
After the injector installation two weeks ago , we discovered the fuel rate pin in the pump was stuck in the EXTREME LEAN, or LEAST FUEL RATE position. As you can guess, this does not provide optimum performance, but nonetheless, the truck pulls the gears like a damn Freightliner. The new pump goes in Monday, and is turned up 30%. The truck has always given at least 22 mpg. , and doesn't smoke, unless I turn the pump too far over to make it. Boost with the pump in the extreme lean setting as it is now is about 20 lbs. , with a nice pull. After the new pump is in, it should be a BRAVE NEW WORLD. I'll let you know how things work out.
Long may you run.

What type of injectors and how much improvement do they give? Did you install? If so is it difficult?

Sorry for so many questions, but I have a Banks stage III power pack and pump is turned up. Mine smokes a little under low boost or towing when I romp on it. Mine heads for 1200 deg egt on long pull in 5th. I could pull most hills in 5th, but afraid of egt. Do injectors help?

Don: We installed the injectors at Ted Jannetty's facility. The truck had the banks muffler removed and Ted installed a straight thru muffler, with good results. Ted precisely checked and reset the pump timing to optimal setting. The injectors are Bosch/Cummins 12v large. Improvement is: LARGE seat of the pants pulling in all gears, quicker spool-up, more useable and noticeable torque. This is due to the combination of all the above, and with the added burden of the discovered delivery rate pin in the least fuel position.
Have you tried backing off on your delivery rate, or the star wheel?
I know you said the smoke comes on at the low end, are you sure you're running clean at the top end?
The injectors were installed at the shop, the truck was in for the timing, and the muffler/pipe also. You can install your injectors, I suggest you check out your shop manual for the procedure, and make sure you have the new copper washers with them.
I recommend Ted Jannety, check out his site at the links, E-mail him from his site If I haven't answered your questions.

I have not messed with the pump in any way other than to turn the fuel screw? clockwise(in) about 1 1/2 turns. I then had to turn the idle screw back to get idle down. Will adjusting the star wheel help? I saw where Diesel Dynamics has a new replacement plunger that is supposed to help the old rotary pumps. $150. 00. What do you think? What h. p. and torque will you be putting out gueestimate or are you going to dyno it?

thank you so much for the info.

I had Bruce Mallinson (see past issue of TDR) turn up the pump. With a 16cm housing and no other engine mods I now get 25lbs of boost and lots of smoke. I am happy with the HP gain but the smoke when I shift and get back on the throttle is a little exessive. Any Ideas?

Neilman,

I do not know how they turned up your pump, but does it get hot (EGT) under a load? Will it make 25 pounds boost empty or loaded?

O. K. you First Gen guys and gals: I'm going to throw out a picture illustration of the Bosch VE44 injection pump on our pre '94 Cummins motors http://www.tstproducts.com/pump_adjustment.html
I've found-starting from the factory settings-
1) Turn the power adjustment screw in (clockwise) 1 to 2 turns. This will increase the FULL LOAD fuel, then you will have to:
2) Adjust the idle speed screw out(counter clockwise) to lower the idle speed to approx. 950 rpm. (Your full load adjustment moved an internal spring plate and fooled the idle. )
3) The Fuel Delivery Rate can be adjusted mildly by loosening the locknut under the cap, and turning the setscrew in (clockwise) about 1/4 turn. The fuel delivery rate adjustment is the one to watch for when making smoke at snap-idle, or on take off conditions. Adjust it back slightly till the smoke stops. Now we come to the real FUEL DELIVERY RATE adjustment:
4) Fuel Delivery Rate Pin/Diaphragm can be adjusted by carefully removing the 4 screw cover, noting the position of the punch/tick mark on the steel center diaphragm washer. 12:00 is the factory position, moving (rotating) the diaphragm (tick mark) to the 3:00 position will bring on the MAXIMUM fuel delivery RATE. Watch your EGT. Obviously, you can rotate back toward 12:00, if the EGT or smoke gets excessive.
If your smoke is only at full throttle load - back off the full load screw.
If your smoke is at low end thru pull-up - back down the delivery rate.
If smoke is heavy at immediate start-up - fine adjust the smoke setscrew.
Look at things in their original position, mark them, scribble some notes to save for reference, and LOOK AT THE PICTURE of the pump.
when you're done you'll be making BIG POWER, and will be able to relate tales to your children and grandchildren about the FIRST GEN. CUMMINS/DODGE, built the way God and Nature intended.
The above hopefully helpful tips are brought to you in the knowledge that you would not do any adjustments that would void your non-existant warranty. https://www.turbodieselregister.com/memberimages/r0300343.jpg

Old School,
Your the man. This is the Explanation that I was looking for. I have been playing with the Fuel Delivery Rate, with no noticeable improvement in the smoke output when the throttle is pressed with enthusiasum. I will take a look at the Fuel Delivery Rate Pin/Diaphram adjustment now!

Old school,
thanks for the info. It is also available on Dave Fritz's Rampage. They recommend removing the cover(4 screws) and rotating the diaphragm @120 degrees??. From 12 to 3 would be @ 90 degrees. I have posted before what do you think of changing the pin out like Diesel Dynamics recommends? If I rotate the diaphragm will it get hotter? I like mine now, but want more power. with 14cm2 wastegate housing mine wants to get hot on long grades. Have to get back in 4th. Power no good if you can't use it.

thanks again
Don

Hello Guys: Glad you found the post useful. I'd go to the 3:00 (90 deg. ) as max rate for diaphragm rotation. As far as EGT... if you're running a 14cm housing, more fuel will give you more EGT. I'm running a 16cm housing, with no waste gate, and EGT is 900 max; and I'm looking for more fuel. I'll have it with the new pump. Can you lay your hands on a 16 cm housing w/o wastegate? It might be well worth your while to try it out.
By the way. . thats the right thing to do about long pulls/upgrades/headwinds - downshift and back off a bit. You know what excessive EGT's are all about.
I've checked out the Diesel D site and saw the modified pin setup. Looks ok. My problem is that I can't remove (slide up and out) the original diaphragm fuel rate pin, as the action pin which contacts the taper pin on the tapered eccentric, is stuck in the lean rate setting position, and won't allow the max fuel rate delivery. New maximized pump is going on, and I intend to move the diaphragm toward 3:00, along with all the other moves we've talked about. I like the idea of the remachined pin eccentric, though.
regards.

You aren't kidding about being lean. If you get 900 max(I am assuming in manifold as opposed to after turbo) you are lean. you will really be cookin' when you get some fuel in that baby. How much boost are you makin' now.

I figure the 14 wastegate is a little better than the 16cm2(correct me if I'm wrong). It should spin up faster shouldn't it? I have been told more boost would help me cool it down. It seems to perform like Banks said. They show 21 psi, which is what I get loaded. Empty is only @17 on the floor. Seems to come up to speed real quick and then boost falls off, I think this is natural. Just lookin for more ooomph. Let me know how the new pump goes. I do not like to smoke so much. I wouldn't mind but as a young single guy, it would not go over to well if I went to pick 'Ol Girl up and she couldn't see the truck for the smoke. Women don't seem to appreciate some of the finer things in life.

I took the cover of the pump and turned the diaphram to the 3 o'clock or 90 degree from stock position. I drove around a bit and found it to give me 2 more lbs. of boost for a total of 27 lbs. empty on flat ground. The throttle response is better and since it was dark outside I could not see if the smoking condition was better of worse. Thanks again for the tip and increased understanding of my pump.

Hello Guys:
Neilman - glad to see the adjustment went well.
Big Don - First of all, I was in error. I realized it when I was at Ted Jannetty's shop today and we were discussing your conditions. The 14cm would be better than the 16cm. Actually, a 12cm with wastegate may work well. Get in contact with Ted, his link is on this site.
The new pump is on, and working great in concert with the injectors. The power is SMOOTH, and LARGE. the combo brings a whole new meaning to EASING ON THE POWER. Ted and I were grinning throughout the road test. Driven properly, the truck will not smoke, and has an outstanding smooth pull up in all the gears. The power band is OUTSTANDING, and a real torquer.
Now as we went on our test run, I had the opportunity to screw it on and mash the pedal a couple of times thru the gears. Boost was like nite and day in rate and peak. High twentys - EGT is around 900 - hadn't really pulled and opened it up, as traffic was heavy, and this Cummins makes speed quickly.
Oh Yeah... this should please you. . the truck will lay out a nice little smoke if you choose to get on it LARGE, as it should.
To recap: injectors - Big A** 275 Ted J.
pump - 30% up, bench flowed Ted J.
16cm2 holset turbo
exhaust - 3 1/2" w/ straight muff.
As the days go by, I'll post some observations.
Regards.

All right Old school!!!

Sounds great. Did you swap pumps or have yours built? I think I can do the injectors myself, but I believe I will call Ted J. Keep us posted.

thanks
