What's in a name? Lucas injectors

[DieselBuzz]

#@$%! Is there a difference between Lucas's "Old blue specials" and the "Prince of darkness" injectors? Or is this just different peoples nick names for them? (I'm not that mad, I just thought this new smile is funny)

The injectors are made by Lucas, now called Delphi. They were nick named Old Blue's by Big Don, I nick named them the POD's or Prince of Darkness because that's is what we used to call any lighting system made by Lucas cause of leaving us in darkness when the lights went out :--). They're good for 52 rwhp in a 91. 5-93 factory intercooled motor, 28 rwhp in the 89-91. 5 non intercooled motors. I just found a source to get them at a better price... . guess what's going on sale for the month of Febuary

Injecters

Piers= Are you still out there. Just put my new injecters in to day and was going to call you and tell you. They work. But my EGt went out of sight and my bost went to 38. I am kind of worryed and need some inpout on this.

They realy jumped the power .

Those things have only 4 holes... . 295mm to . 305mm range, according to Lucas. It's GOTTA smoke and soot up the oil pretty bad... Not denying the power, just commenting on the injector's specs... Not to mention the Delphi wholesale price is pretty darn low

 

[DieselBuzz]

Holy theory!

Ok, so four big holes are bad. Does that mean that six smaller are better? What about eight? or ten?

I think you might be a little biased because of the name. What if we all start calling the Lucas injectors "The Prince of Power Wagons" or "Old Power Wagon Specials"?? Could that make you warm up to them a little?

LOL!!! I love it!



If memory serves, the 215's have 6 holes, the PW injectors have 4 and stock is 4 for the earlier trucks ,as well.



And no, I have nothing against the injectors... I just hate smoke...

You are a good guy! I have consistantly poked at you with my replies and you take it in stride.

All depends on how you setup the pump, I can install the POD's and have very little smoke coming out... or you can have your pump cranked as shown by Harlans pre POD boost of 34lbs, now you can turn down the fuel some [put less stress on your pump] and still make more hp. The Pod's and the Bosch/BD/PW all share the same spray angle and all have the capability of sooting up your oil, if the fuel on the pump is turned up. Remember these injectors come out of a stock engine from Cummins, they're not some EDM'd to to limit monstersOo.

I would think that up to a certain point, the faster you can inject the fuel under cruise / light load conditions, the better your fuel economy should be - assuming, of course, you find the optimal timing. Theoretically, if you could keep from smoking with the Lucas injectors, you should be able to get really good milage.



Piers, since you did a straight swap from stock to PW, to Lucas injectors, I was wondering if you could give us a pretty close comparison smoke-wise, assuming the pump is stock, and you have plenty of air.



I know that a totally stock truck, with the PW injectors and the 18 or 21. 5 turbo housing, will puff a little gray when lugging, and put out a mild haze at moderate rpm's (1800-2000). They apparently smoke little to none if you have the 16 ( at altitude, all bets are off) and I'll give you guys a good review for the 12 when I put my injectors in. (I got them, just gotta have time to work on it).

I asked this on another post, and just wanted to confirm. Will the 215's out of the later model trucks fit in a 92 first gen?? On the other post they said the threads were different. Is this true?? Are these the same 215's you are referring to??

 

[Piers]

The only reason the 215 injectors won't fit into a 1st gen truck is because the nut on the injector line is 14mm for the 215 inj. verse the 12mm that comes on the 1st gen.

thanks Piers

Thanks for the response piers. Ive been bugging Brandon with all my 12valve/1st gen questions lately, He keeps telling me to call you. LOL any way, thanks for the reply. I wonder if i could put the 215's in the lathe and rethread them????

 

[Power Wagon]

I noticed a typo I'm going to correct here... . the PW injectors have 5 holes. (I went and got one out of the box just to be sure!!!)



I put a set of 215 nozzles into a set of 1st gen bodies. It requires you change the spring, spring seat, and intermediate plate, to do it. And of course, you have to set all the pressures with new shim packs... I took a set of takeout 2nd gen injectors apart and put thier guts into a set of earlier bodies to make it work.



Our best evaluation is that there is a small loss of power over stock injectors in a '92 engine. Ergo, this is not really a performance swap. HOWEVER, if you were running consistently at very high altitude (say, over 6000), I would consider using these plus a 12CM wastegated turbo, to cut down the smoke. With thier 6 fine holes and a moderate fuel amount, it should be about the cleanest thing you can do.

 

[rubberneck]

Powerwagon, so what you are saying to me is dont waste my time with the 215's. I am looking for more power, not less smoke. The truck has a 14 cm wastegated housing, and we live at sea level, so smoke is not an issue. guess i'll have to get a set of pod's or pw's. thanks for all the info guys.

Wow--this is very interesting! Part of the reason I bought my PW injectors was because they had 5 holes instead of 4. I'd hoped that this would give a better spray pattern, possibly resulting in better milage



Are there any other injectors you know of which have 6 or more holes that could be modified for use in '91. 5-93 engines? I don't imagine it would be very likely that DD or someone else would come out with "reamed out" (extrude honed?) 215s for the 1st gen that would give +30 to +50 hp?



Oh well...

Midnite,

Your comments are exactly what I was thinking. I have had the Powerwagons for about a year and the truck runs great, but then more of a good thing would be better. I have been thinking about the POD, but then just maybe if I wait a little longer something better will come up.
