Those using injectors other than POD's...

[BushWakr - RIP]

Hey guys, I'm looking for some detailed info on injectors. I have the basics on the stock and the 185's as well as the POD's, but I'd like to have any guys running something different to really dig and get some facts.



1) What application are they from?

2) What is the advertised HP rating over stock?

3) What is the bar or pop-off pressure?

4) Are they large sac type injectors?

5) How many holes in the tip?

6) Do you know the flow rate/can you find out from vendor?

7) Have you dyno'd them and what RWHP did you get?



You may have to push a bit to get some of this info, but anything you can dig up would be a big help.

There are one or two guys interested in looking into alternatives for the normal "run of the mill" choices we currently have.



Thanks for your help...



Bob.

I would really like to change out my injectors. Can someone please just make a list of options and the differences of each injector. I really like POD's but they are a little out of my price range.

Other Injectors

1) Diomond B 370, marine version of the 5. 9 litre engine



2) advertized 370hp



3) mine pop off at about 3400psi which is close to 245bar



4) yes, they are sac type injectors.



5) 5 holes



6) never have dinoed, sorry



You have to change the top of these injectors to fit the nut on our fuel lines.

You also have to change the pop off pressure from 260bar to 245 to get them to work right.

They will probibly cost more than pod's because of the work you have to do to them.



Why did I do it?

pod's weren't discovered as a mod yet.

I am trying to get those specs on my injectors. They were rated at a 40/42 h. p. increase. Will repost.

I'm running ADT injectors. I thought they were advertised for ~ 60 additional horsepower. I haven't counted the holes in the tip or haven't dynoed it. They are classified as industrial injectors.

Flow rates would be interesting too.

Hey Bob, could you post the specs that you have on the injectors that you know about? That would help me out telling you about these injectors that i have right now. There not in the pickup yet so i could get the information on them easy. I bought them from a friend of mine and he said his mechanic bought them from BD and there good for 60 horsepower. Can't wait to get them in.

Chris,



Oh man..... I'll try to get this right, but, it's only been recently that I've started to look at specific values etc.

I'll go by memory.



The stock injectors were 240 bar I believe, and 5 hole

The Bosch 185's were about 245 bar and 5 hole

The POD's were... . I want to say 250 bar and 4 holes.

Each will have similar or slightly varied spray angles... for example 140*angle, 145* angle etc. This is important when trying to keep the fuel cloud inside the piston bowl for efficiency reasons.



Our trucks have the injection take place at an angle to the bowl because of the 'side mounted' style of the injector hole. The newer trucks have center injection (my word) straight down into the piston bowl. That is more efficient and applies the pressure to the piston (on combustion) straight down and not at an angle.



One of the things that I've had to really try and keep in mind is that when you order/buy a set of injectors, they will vary in Bar between each injector...

In other words, you may have 3 that pop-off at 245 bar, 1 at 249 Bar, and 2 at 244 Bar. Generally a slight difference is negligable or not even noticed. If it is too much of a spread then you will see differences, most likely on a dyno for example.

One of the things that we as consumers can do is convince the vendors to match each set, or balance them so there is little or not difference between the set of 6.

In the high end HP area's most sets are probably balanced sets.

It adds to the cost since you're taking a brand new injector out of the box, putting on the test bench and checking it. Then if need be, shimming is changed and re-tested till they are all within a certain range.



Some shops will order in injectors, re-brand them and sell them as theirs. It is done alot and is normal business practice. The POD's for example are actually Lucas injectors which is now owned by another company..... the name eludes me at the moment.

The name POD came about as a bit of a joking term referring to "Prince Of Darkness" due to their tendency to smoke a tad...



Ok, so after saying all of that someone please correct any mistakes. I was wanting some more info on the other types of nozzles being used in our trucks aside from the 3 or maybe 4 obvious well known ones.

Bob,



What year are your stock injectors? All of my intercooled trucks I have messed with the injectors in, had *6* holes. Not sure about the 11/90 I just got. Know it needs them; had one retaining nut come loose, tightened it up, and forgot to complately tighten the injector line. Made no difference in how it started and ran, except I got fuel EVERYWHERE. But it has 242K on the original fuel system, so I cant complain. Still gets 20-21 mpg with 4. 10s going 65-70

The injectors from ADT are considered a Industrial injector. I was calling them by wrong name. Don't know were i got marine. Sorry. But was told a 40/42 h. p. gain. Was also told(not pushing those injectors now)that Pods were overkill for towing and daily drivers?Maybe egt issues/smoke/smoothness?That the industrials were a good compromise for all around performance as well as price. There on sale at this time. So are PODs At ADT.

 

[Old Smoky]

Hopefully Dave posts the results of his new injectors here. Oo.

I will try to get the info of the marine engines that we are working on at work, B, lucas pump, small nuts, 210hp.
