Dragon Flow Injectors

[Cowpunk]

Is there anyone who can tell me about the Dragon Flow Injectors from Industrial Injection.

What do you want to know?

 

[JR2]

Do a search, you will see they are quite popular among the high high HP guys, especially in the NW.

 

[Cowpunk]

How do they compare to the regular 370 injectors or to the DD Stage 3 extrude honed injectors?

Are you shopping for injectors for your 03?

If your talking about a 12V there is no comparison and I own both 370's and Dragon Flows and have for two years.

I am certain that everyone who reads your answers Jim enjoys how much info you give to support them. That one right there is a classic.



So I guess if you need a better question to answer so you can be a tad more informative to those who really are curious about the difference between them here you go.....



Answer this for us,the 12v owners,who would like to know... .

1-What noticable gains have you seen with these injectors over the standard marine 370 or DD3's which has been used for many years in our trucks?.

2-Knowing the DD3's are rated 70hp over the marine 370 and have a better spray pattern,what will the 12v owner gain by purchasing these over them?.



See initial cost to me is not a determining factor when making purchases for my truck however end result is. IF I am going to spend twice the normal cost amount for injectors,then the end result when its strapped down better reflect the paid cost.



Most owners want their wallets output for their trucks to show itself in results when strapped down to a dyno,longer distances on pulling tracks or in ET gains on timeslips... . Andy

DD3's are very similar to our Stage 2 injectors which are known by some to be Dragon Flies. These are for hp's in the 550-650 range. Dragon Flow Injectors are much larger and they have much more EDM work done to them than most injectors would ever see. They can make up to 875hp if pump and turbo's are large enough. You can drive them on the street if you are careful. They can run with less injection pump if you want but are made for bigger hp. Thanks

Thank You for your quick response and it does answer some of the questions for me.



Being that said again,a question from the peanut gallery here... .



Knowing already that guys have made well over the 600HP mark with the marine 370's and thousands of street miles have been driven with them I'll ask this question again... .



At a price of 50% more(Your Stage 2 & 3 370's) and 265% more(Your "Dragon Flow" injectors) than off the shelf 370's does this mean the owner can expect the same amount of HP increase for his dollar spent?.



See I am not a rah rah kind of owner and when spending my hard earned cash it will take more than a cheerleading section to open my wallet. What will make me spend my money is facts. Facts which tell me that for the amount of extra cash the companies want for their products,over an already proven part,they will assist me in making gains in power equal to the money they want. Meaning,you say your product is the way to (xxx) amount of HP and we already know that another part makes that amount of power at a more cost efficent price,tell me,the owner,why spending 2x or even 3x the cost is beneficial to me OR show me I will make 2x or 3x the amount of HP over the other part for the desired money.



I am not trying to begin a rift or vendor/product bashing argument Brett so please do not take these questions that way. What I am trying to do as a owner and a consumer is trying to have you see this from our side as consumers. Show me they are the real deal and a performance enhancement whose cash investment and HP gains are relative and you'll go along way to making many sales,including mine... ..... Andy

Hammer,

Here are just some thoughts I had while reading your post.



You seem to be saying that if you are going to spend x times more money then you expect it to make x times more horsepower. Is that correct? While not considering the other benefits that some injectors have over others even though they may make the same HP.



I guess the $$$/HP ratio might be the most important factor for a competition truck but seeing how several members trucks are also daily drivers/tow vehicles there are several other factors that many of us consider. Personally I will pay more money for a given injector even if it produces the same HP but does it cleaner, smoother, and/or possibly with less EGT's. These things cannot be quantified on a race track or a dyno but they do hold value for many of us.



FTR - I know do not know anything about II's injectors so I am not commenting about them directly.

370's suck b/c they haze at idle been there done that. if any of the others provide power and no haze at idle buy them.

The 370hp injectors that you talk about are also available at our place. To answer your question, we have to alter these or other injectors. The more labor and material we have to use to make bigger and better injectors, the higher our price will be. Stage 3 injectors flow 30% more fuel than your 370hp injectors. Tuning your truck is some thing that is more involved than taking the camplate out and blocking the wastegate actuator. When you get into big hp with large fuel delivery you can get into problems like semi hydraulic locked injection systems. The injectors flow is too small to keep the load on the camshaft and lifters from causing their failure. The fuel delivery is determined by the injection pump, high pressure fuel line sizes and injector sizes. They do go hand in hand and need to work together. You could use 370hp injectors with a very large injection pump and see good numbers, but at what cost to the injection pump? But no matter what, bigger flowing injectors will always make more hp unless more air and timing need to be added. This topic is too large to be talked about in detail on this thread. We do know what we are doing and if you would like some help, we will help in any way we can. Thanks
