POD Injector numbers

[TexasTurbo]

My dreaded Lucas Prince of Darkness injectors arrived in the mail recently and hopefully I'll have time to put them in tomorrow. The injectors I received have the following markings and numbers:



Two injectors have - LJC67605#CNG Lucas - on the main body and - 9333- on top. The # is where a letter or number has been etched out.

Three injectors have - LJC67605# ML CAV (or CAW, looks like a brand mark) England - and - 9333- on the top. The # is where a letter or number has been etched out.

One injector has - LJC ###### GOG Lucas - on the main body and - 9333 - on top.



It's my understanding that only the - 9333 - is pertinent to the application, but I wanted to check with those who know before sticking them in. Thanks for any help.

Yes, you have a matched set.



The numbers after the LJC are the critical items. The letters following those numbers are minor revision things. Usually unimportant.

Lucas POD Injectors

The numbers on my POD injectors are also etched out for some reason. Rick.

PW, thanks for the info, I'm going out to put them in now. I'll let you know how it turns out.

 

[bvanetten]

Mine are etched out also...

I got some from Piers and they are not etched out????

Is it a good idea to put these in without any other changes? What performance improvements can be expected? How much do they cost? Where is a good place to get them? Should the timing be adjusted?

These injectors will make the most difference. Yes you can leave all else stock, but do put in some guages, boost, egt. They cost about 400 bucks and you can get them from Piers Harry. Also he is a very good source of knowledge on these engines. Tim

I had POD's put in a couple weeks back. I had some smoke at idle issues which were corrected today. Seems they came with the wrong washer thickness. Piers put in a brand new set, new washers, (thinner) and presto

I'll have to run a tank of fuel through em to see what mileage diff. there is.

I'm seeing about 5 pounds more boost (with slightly less fueling), much better throttle response, and excellent power increase even over the 180 HP injectors I had in before this.

In conjunction with this the timing was advanced to 15* to accomodate these injectors. Piers is adamant that 15*-17* is just fine for these injectors/trucks. I must say that it really responds nicely now.

I also had the pyro moved to pre-turbo... . talk about an eye opener :--) from post-tubo.

I'd never install post-turbo again!

All in all, these are an excellent enhancement for the truck.



Last, I can't say enough about Piers and Al at PDR. No debate, or arguements, the first set seemed too smoky, out they came, brand new set in... period!



ps: anyone who thinks the 160 HP P7100 pump for the second Gen's is no good for tuning... ... . WRONG :--) :--)

Piers took me for a ride in his rocket... . Holy Crap !!!! That thing just rocks !!

At 3500 RPM steady throttle he nailed it and my head snapped back and hit the seat heading for 4000RPM. Absolutely amazing is all I can say. He dragged it down to 1000 RPM in 5th gear and accelerated up through 3000 RPM,,, smooth as silk, no bucking, hesitation or smoking. It really is a fine piece of work.



Anyway, thats my . 02 worth. No I don't get paid for this

I just gotta respect someone who's good at what he does.

BushWakr,

I got the POD's in with few problems, BUT, my truck smokes like mad now. As far as I know, the pump had never been tweaked ( I never tweaked it, I puposely left it alone in anticipation of installing different injectors). I did install the thick washers, the same that came off the old injectors. Also, my Cummins book called for 0. 06 in. thick, which are the large washers. Are you saying I have to run the medium thickness washers? Any help is appreciated.

BushWakr,



What kind of differences did you see with the pyro installed pre turbo?

With the pyro post-turbo the needle came up with a sort of ... "ya, ya, I'm getting there" attitude. I rarely saw WOT temps that went over about 700* - 750* on a Bonsai run.

Now, the same run with 25 psi generates 1100*F and the needle is up there right away no hesitation just a fast, smooth climb to 1100*. It stayed there for a full 15 -20 seconds (thats as long as I could stay on it) and did not go over. Piers says that the last 'couple hundred' degrees sometimes seem harder to 'get' than the first temp spike, and so far my experience seems to bare that out... . so far. Anyway I'm told 1250* all day long is ok, if you hit 1350* your good for 1 minute out of 5, and at 1500* you got 20 seconds to bail or its Chernobyl time:--)



I was very impressed/surprised to see the difference in gauge response, and temps. Using the old formula of 10*F for every 1 pound of boost, then the one time I hit 850* post turbo was only pretty much very close. 850*F + (25psi X 10*F) = 1100*F



But since I'm getting old-ish I don't wanna be doing Math while I'm driving



Hope that helps.



Regards, Bob

Ok guys, I have a question. What would be good mild injector upgrade for my early 91 non-intercooled?

When I look on the commercial sites, they list injectors for the intercooled engines only.

I don't tow and rarely haul very much weight. Just planning for a little more umph when it's injector service time. (Or when I convince the financial manager that it's time)

I have a pyro mounted pre-turbo and on a recent "bonsai" run ( I like that expression) I saw a scosh over 1100, at about 90 mph, 2300 + rpm, 20-22 psi boost, just a light trace of smoke.

I'll be installing a 16 cm housing in a couple of weeks as well.

Any suggestions?

Thanks!
