I'm Just wondering if anyone has owned/tested both the PODs and EDMs on a 1st gen (Including Don M). If so, I was wanting to know if the EDMs were worth the extra money. Was there an HP difference, noticeable Fuel mileage difference, etc?

My truck is gonna be used almost solely for trips to and from work with the occasional trailer towage. The trip to work consist of 55miles of interstate and HWY driving at speeds between 55 and 70 mph. I am not looking for maximum power out of my truck, just alittle extra power to make it more fun to drive (200-225 is all I need). I'm not into masive amounts of black smoke, but I can live with alittle extra (I like steathy power). I have NO intentions of EVER adding a high RPM Gov. Spring, I prefer to keep my revs down and the lowend torque up. Actually looking for an ecnomical auxilary OD unit so I can lower my revs at higher speeds.

Other future plans include a 16 Cm housing (possible conplete different turbo and ATS manifold), Timing advance, SRW conversion, Exhaust (3.5-4"), TAG, And of course guages before all of this.

 

I am also interested in that comparison. I want the power of pods without the smoke, gobs of power when i want it and fuel efficiancy when i dont.

I've tried both. It's hard to beat the POD's without doing some testing with custom nozzles/honing.

Could you explain that statment alittle better? Are you saying that you found the PODs better? And if so, why and in what aspects did you find them better?

Which injectors are you running and what is an Air Packer?

 

It is the hich tech term for turbos ... as in they pack more air in.

 

Old Smokey is just using non-desrcipt terms to conceal the fact that he is somewhere close to the 500rwhp mark.

 

When I installed PODs I lost 3 MPGs across the board, I still run PODs because of the huge power difference. I was thinking EDMs would give as much power and better milage but know one seems to know the answer to that question. I have been meening to talk to Rod at Wildcat Diesel and ask the question.
If PODs are $400 and EDMs are $700 why buy EDMs?
Please, somebody answer that question.

 

That's easy to answer- if you don't want or can't have smoke but you want more power than 185's can deliver, you need EDM's.

 

the EDM's were 550

 

Maybe I should have written centrifugal air packers to be more specific.

I didn't lose any mileage with the POD's (mine were honed) compared to the stock injectors, or 185's. This really depends on the right foot though. The EDM's I tested made less hp, and had white smoke issues. This testing was a while back though. A newer 'hot' set that I recently heard about made alot of black smoke. POD's do smoke because of the large sac nozzle design, and poor atomization due to the four large holes. With mild pump adjustments the smoke is controlable. The cost of the POD's is considerably less also. To be honest I havent really found a set I like. They seem to be clean and make modest power, or smoky and make good hp. The best I have seen would have to be the DD3+'s. They make respectable power, are fairly clean, but are hard to get and expensive.

Other nozzles such as 215's, 300's, 330's, 370's etc can be used in a first gen holder, and be honed to give you the power that you want. This requires some trial and error though.

There are other less popular injectors available. Most work pretty well, but I like to know exactally what I'm getting before I buy it. I recommend the POD's if you want a good power upgrade, can live with a little smoke, and on a limited budget.

Yes, Mike is correct. Last year he tried some prototype injectors for the 1st gen I built. Several sets. We tried the 8 hole style like I used with great success in the 24 valve. Unfortunantly the the 8 hole style just wont work in the 1st gen engine because the fuel injection pressure is not high enough to get the correct discharge curve. The results were less than perfect, but they were "test" or "prototype" injectors. I spent days making those nozzles, but wanted to see if the increased number of holes would respond well. To have it end like it did was not what I wanted, but it gave me some data I needed and answered some questions.

After the testing with Mike ended I started some with local guys here and found out just about all I needed to know about the 1st gen and the best injector style/type we need for the engine. We now have several power levels that will out perform the PODS and the 185's. In smoke, HP, and TQ.

We have many sets now in the field running well for guys.

Before things get out of hand though it is important to remember that the injection pressure of the 1st gen pump is less than we would all like and will smoke at high HP settings. The second thing is I cant seem to keep a steady supply of core injectors to build sets of customs into. The third thing is the demand was soo low for a 1st gen injector that we just dropped the program in the late spring this year. The cheapo POD's were hard to compete against in the first gens and the cheapo 370's were hard to compete against in the 12 valve second gens. Most folks would just as soon deal with a little smoke and not pay any extra for an EDM. I totally understand and dropped the program accordingly.

We still build a few sets here and there, but it is rare. Hand built one at a time custom nozzles will never compete in cost like a mass produced Lucas POD. Performance is another thing though

 

Don,
If you can build me nozzles that make the same power as PODs and less smoke, then Im interested, If you can build nozzles that make more power and the same smoke, I am still intrested.
I have a set of stock cores sitting here waiting for some mods.
There is a good chance that I will be dynoing in Denver this Saturday the 24th. Im hoping to be in the 290 range now, I am also hoping to dyno at Edge on August 14th, maybe I can do a comparison between those 2 dates, of coarse there is an elevation difference between Denver and Ogden Utah.
Let me know what you can do

 

Ok, I see everyone mentioning that the PODs are the best for limited budgets, but with if You just want to absolute best injectors with little or no smoke at max power?

 

I'll throw in the monkey wrench on this one..
I have the Bully Dog "+50" injectors...absolutely zero smoke at idle, very little smoke during hard acceleration, dissapears when boost gets to 15 or so.
Gives my truck very nice mid range power.
I got these because I didn't want the smoke that POD's are reputed to have.
I am very pleased with these injectors.

Hey J How about a price on those nozzles?
Did they affect your fuel milage? Im not so worried about the smoke other than if you have 2 sets of nozzles that make equal power and one smokes and one doesnt, that just tells me there is better atomization, in turn better fuelmilage capabilities.
