The guy that talked to me about his used DDP injectors said that he thought he had one or two going down. So I believe that I will go with Ryans and just drive out there so I KNOW they work right while I am at the shop. Thats even if I can still get them if nothing comes up I hope. Then I have to pay for more tuning .

 

mine are good for towing too..that was my main concern when getting them..its all in how they are tuned..you can tow with hybrids and not get hot with the right tunes ...

Larger nozzles- By installing larger nozzles you are makeing the nozzles less restrictive so that more fuel will flow out of them with everything else being the same. Stock injectors with stock programming and larger nozzles will get more fuel out and make more power. Stock injectors only modified to have more fuel capacity with stock nozzles and stock programing will run exactly like stock injectors. In this case the only way to get more fuel out is with a chip to extend the open time of the injector and/or increase the Injection Control Pressure (<ACRONYM title="Injection Control Pressure">ICP</ACRONYM>) to push more fuel out the nozzle. On the same note if you say make a hybrid (installing a larger 7mm plunger and barrel out of a DT466/I530E injector) and leaving the intensifier piston the same will effectively reduce your injection pressure. This less injection pressure will make less pressure at the nozzle and will actually flow less fuel with a stock nozzle than a bone stock injector. So to get the fuel out without a chip you would need larger nozzles.

There is also a point where the stock nozzle just wont flow enough fuel to get the desired amount out in a realisitic time frame. That's why high capacity injectors require larger nozzles to use that capacity.

 

for the price thats how i would do it..but i live so damn far away...hope things work out for you...ill have your other thing in the mail tomorrow..i for got all about it till now..sorry man...

 

Now I'm slightly confused... I thought that hybrids were able to push more fuel with less oil because of the larger barrel/plunger assemblies. Is this correct?

 

yes cause the intensifier piston is changed..

 

Okay, thanks Ron.

 

I know what you mean by this Ron. The bigger the nozzle, the more fuel. I agree with this but, with the bigger nozzles they let the same amount of fuel go into the cylinder at a faster rate. Bigger particles means hotter burn. With a smaller nozzle, you get a finer spray with the same amount of fuel, which burns cleaner and cooler. Jody told me that with more presser from the HPOP, you can make more power, because it breaks down the particles of the fuel smaller, which burns cleaner and faster. When you have 160 injectors, thats all you will put out. The tuning and nozzle size will make the difference.

Not taking away from you Ron, but I am learning about this and just telling what was told to me.

 

Gotta tell yaa, i got a way to go with supporting mods till i get to these injectors but i,m learning alot here, good luck JD.

 

I will tell you that the Swamps SS 175/146 that I put in really made a difference in my power. But you will have to buy a chip or if you already have a chip have it tuned to them.

 

You will get more power out of a set of hybrids than any of the others when you take the total cost into consideration. Some of the other single shots will work fine to a point, if they are small. To get more, you need to step up to a better HPOP, even dual HPOPs.

So if you want to slap in a set of injectors and a turbo upgrade (yes, you need this or you won't be able to clean it up) so you can make between 350-450hp, you can go hybrids and no oil mods, or go with a B code or whatever single and get better oil. Add it up and decide.

I believe my injectors may be capable of more than my engine can handle as they are right now. They can be upgraded to the largest units Swamps makes, but I will probably never see that day.

A decent set of run of the mill hybrids is capable of about 450hp on a good stock HPOP is what I am trying to say.

Final thought, this ain't cheap stuff. The stock turbo runs out of breath well below 350HP. Well below. Anyone that could manage anything close to that with the stocker is pushing some poor quality air at that level, and on the edge.

Just some thoughts. Don't know what all you and Ryan discussed JD. I know he can build some great injectors from what I have seen though. Sounds like he has excellent customer service too.

 

Well you got all the mods really needed even the turbo mods from what I understand for stage 2s you really don't need alot. A better fuel system really helps out and a bigger HPOP say Terminators modifed stock.

Thanks Ron, like I said I was in no real big hurry I won't be installing it till Feb I would say.

Eddie what Swamps did you go with the S/175/173 that were 1050? If they were really a good bang for their buck I might consider them.

 

This is what I put in. You can use these without going to Big Oil and spending way more. But with the Correct tuning they will produce more hp than listed
This is from there web page. Cost $1575
175/146
7.3L Injectors 175 mm^3 The 175/146 injectors are a terrific upgrade for those looking for efficiency, as well as a modest power increase. The 175 single shot injectors retain the OEM ("146"nozzle), use NO more high pressure oil than stock AD's, yet flow 25+cc's more fuel. "Off the shelf" programmers, and "generic" chips will not work with this style injector, as injection timing and fuel feed rates have to be adjusted to accommodate the single injection event. Reprogramming of TS performance chips, as well as Bullydog chips are offered at a discount at the time of injector purchase.

The 175/146 injectors have shown to increase rear wheel horsepower by as much as 60hp. With our custom tuning, we have been consistently increasing fuel economy 2-3mpg!

....and use no less. That is why I went hybrids. I was already easily getting the dreaded ICP below desired level with the stock units. Of course these will throw more fuel in there until they hit the same wall.

Not picking on you Eddie, those are great injectors. Rich has them and his truck runs great. Just trying to get people to think about this so they know what is going on.

FWIW mine are 200s. Nothing major. Just substitute the 200 where your 175 # is. About one of the smallest hybrids you can get. 230s seem to be the run of the mill if memory serves me. My HPOP holds about 2800-2900 ICP at WOT with the 200s. It would fall on it's face with the stock splits. Read that again if you need to folks. If you still have questions, read it again.

 

Mike I agree people do need to really think about this before they spend this kind of money. There is a lot of knowledge on this site but alot of favorites to. I was looking for some economy plus a little power from the injectors. With the right tuning it will work for me. If I was looking for a lot more power or speed I would consider a different truck. Like my sons truck.

 

So basicly Hybrid or bust like Joe stated when this started? How hard will the ICP be taxed on the Stage 2s I have heard the same as Chase but I really don't want to make a great glob of power. Also another question... how long is my stock turbo going to last even if I limit the boost to 25PSI I seen the van turbo worked well with Jermey's B Codes up til the break down. Mike didn't your swamps 200 hybrids run you about 2200?
