370 injectors

[Archive]

Just finished installing the 370's. The truck pulls A LOT harder now througout the rpm range. Is anyone else running the tst #4 plate with these injectors? I am considering going back to the #5 plate because of the low rpm smoke. I have not yet adjusted the afc spring. It is currently adjusted out to the full rich end. I don't want to lose the torque though, this truck now will break the tires loose in 4th gear just rolling on the throttle on the rough country roads around here. The boost is now at 40psi with the big 16cm2 housing. It will go higher I think if I load up the engine, thats just getting on it on flat ground.

I have almost the same set-up as you do,
however, I am still running the TST #5
plate. If you go back to the "12 Valve
Archives" and select the post on "370
inj. 's, gov. sprg. kit, AFC sprg. kit. WOW!"
you will get an idea of how to set the
AFC spring. "Koa Man" has the same set-
up as me and he has "fine-tuned" his
pretty well. He may see your post and
answer anyway. He is pretty good about
that!

I am VERY HAPPY with my truck since I
had all the modifications done! It
doesn't even feel like the same truck
anymore and like you said "it pulls
alot harder now!" That is a fact!

Patriot,
I bet if you looked really hard, you could find a good used heating system #ad

I highly recommend the 370s. You will NOT be disappointed in the power increase. Just ask John P #ad
. I had to use the med. AFC spring to control smoke, the soft spring had too much smoke even with the AFC housing and star wheel pushed all the way back. With the med. spring you need to push the AFC housing all the way forward and have the star wheel turned almost all the way toward the engine. It will still give a good puff on initial acceleration, but disappears as soon as boost gets up. Don't hesitate to install the 370s, you will not be disappointed.

Koa Man I see that you have quite a bit of experience with the 370 injectors, dialing them in and so forth, would you happen to know the Bosch part # for them ? I am having a tough time finding it through my local fuel shop. Thanks for any help you can provide.

I am by no means any expert on this thing. All I did was email Joe D for advice and followed his recommendations. I got the 370s from Joe also. He says there are more than one kind of "370s" and you want to get the 370 Diamond B Marine injectors. I would strongly suggest checking with him for upgrades for your truck. As far as controlling the smoke, the AFC spring kit is a must and just by playing with the housing position and starwheel you will eventually find the best compromise between smoke control and low end response. I have a real tight converter so if the housing is not pushed full forward on my truck, low end sucks. You will be amazed at what a difference even a slight position change in the AFC housing makes.

Hey Patriot, I see you took off your cat. I also did mine this weekend. Do you notice any changes?? Pretty soon me and you are gonna have to hit Atco for a little 1/4 mile action!!! You have the same as me except for 5 speed compared to my auto. What do you think ??? a little wager may be in line too!!!! your "properly adjusted" afc against my torque plate????

Irrigator:

Don't let "Koa Man" fool you about
those 370 Diamond B Marine Injectors.
He "knows enough" about them as far
as adjustment etc. If it were not for
him I would still be driving around
with a "flat spot" or "lag" in my
truck from the new TC I had installed!
"Koa Man"... ... ... . I have told you
before but I will say it again, THANKS
for your recommendations to me on the
370'S!

Irrigator, Piers Harry at "BD" did alot
of the testing etc. on those 370 Diamond
B injectors. You can call him or Joe
Donnelly if you want to buy them. Piers
can be reached at "BD" at: 1-800-887-5030.
You can e-mail Joe Donnelly for his phone
number. They are both great people to
talk to and work with and know ALOT about
these trucks. They sure helped "Koa Man"
and myself alot.

Good Luck!

Does anyone know the part# for the correct 370's? I bought mine from Bullydog and want to make sure they are the right ones before I stick em in. They came in plain white boxes marked "made in Brazil, Robert Bosch, 0 432 131 715". I also don't want to put in a new clutch$$ yet so I'm going to stay away from a plate for now. I do have the BD gov kit coming though since I want new exh springs for my e-brake anyway. I'll then bump the timing to 15. 5, I'm mainly interested in MPG icreases(ya, right) for now. I still can't get used to how much more power this Cummins has over the old 400cid gaspot(Pee-yeew). AWSOME!! #ad

Larry,

I got my injectors from same place as you. I wanted to make sure they were genuine Diamond B series 370 HP injectors. Bosch part numbers are so **** top secret around here, it very hard to verify parts.

Harry Piers was nice enough to check the part numbers for me (same as yours) I even gave him the numbers on the box, body & injector tip.

They are the 370`s #ad


Piers understood the price was unbeatable. Very nice & knowledgeable guy.

You guys are lucky. You have the "good" pumps. I gotta put new delivery valves in my pump to handle the 370`s.

I would delete the part # before a million venders e-mail ya... ... ... hollaring #ad

After driving for a few days with the new 370 Diamond B's installed, I have to say that the truck has really come alive throughout the rpm range. It already ran strong with the tst #4 plate and the other mods but these injectors are taking the power up to a whole new level. I am however beginning to become concerned about my centerforce clutch. I drove home from work today and "accidentally" went home on a country road where I was able to really check out the performance from a dead stop. I didn't time it but the truck pulls REAL hard developing 40psi boost with the big housing. I looked in the rear mirror at approximately 100mph after my run and saw cars emerging through the diesel and tire smoke about 1/4 mile back. Now that's fun! I did however smell the clutch. No wonder Donnelly was showing me the pictures of his new clutch down at Tulare! He knew and he also warned me but I couldn't resist. Bombs away... !

Thanks Bill
Now I can carry on #ad

Rednut, it does run better, but see my post on "engine misses upon acceleration". I still have this problem.
I was going to adj the valves, but decided the cat needed to get lost first.
Like I said, it's better and EGT is down. I dont know exactly, but I'd say at least 75 deg.
"properly adjusted AFC" Vs Torque plate? What kind of handicap are we talking? You'll definetly have to give me a head start. #ad

If you want all that the 370 injectors are meant to deliver, then you're gonna need to install the bigger delivery valves. They really wake up the powerband of the engine, as do the Governor springs.

HEAD START???? I thought that 5 speed was head start enough!!!

DieselB59, do we need the bigger plungers on the "newer" engine? I was led to believe (through numerous posts on this subject)that the 97 and 98 12 valve pump was good to go with these injectors? Please clarify, I was planning this route, but dont want to do anything until I know the whole story. TIA

Rednut, I have the 215 HP engine. I'm sure youre doing better with the plate, but if I ever see you there, I'll race.
I go to Englishtown more often though. It's much closer to me.

I just got back from Deer hunting in the high country and had some fresh snow. The power of these injectors are super, but alittle too super. Even pre-boost there is alot more power, TOO Much for side hills and LSD. I had to chain saw a tree to get out. Luckily no body damage. I'm going to put my #12 TST plate(230/605) back in to get through my other hunts. Towing my house trailer my milage is up 1. 6 MPG over the same pull last year. I'll keep you advised on how the 370s work with the #12 plate.

Another benefit of the 370`s that is not talked about much is the fact that the fuel pump does not have to work as "hard" smashing the fuel thru small injector tip holes that are not really designed to get that much fuel in the first place.

I saw this quote from a post from Stack N Jacked:

"I visit a pump shop three times a week on average and they have shown me multiple pumps that have just puked out because of the fuel flow imbalance. The trucks that are running the smaller injectors and are increasing the fuel are the ones that they see the most. "

The 215 hp injectors don`t seem to be causing the trouble. Its the smaller ones.

HEMI@Dart:

I was not aware that the 370's helped
the pump that much. I appreciate you
bringing that up!
