I am new to this injector business :-[. Unfortunatly I have the bombing bug as my Jeep is not enough to fuel my cravings these says. I am wanting to ad 275RVs, DDIs, DDIIs or similar and a box such as the edge (I know the tranny will have to be addressed too). I see a drastic swing in cost. Bosch 275s are as low as $225 and other similar hp injectors are well over $500. Whats up with this?? . What am I getting for the 100% difference in $$?? Thanks. Tim.

 

http://www.dieseldynamics.com/dodgekits.htm<br><br>here is some info on EDM's

 

I would like to know also... that website dosn't seem to answer the question asked??? maybe I am just looking in the wrong place?

 

275's typically only get you 30-35rwhp<br>Stg. 1's are close to 50rwhp<br>Stg. 2's are around 80rwhp<br>Stg 3's are around 100rwhp

 

BUT! &gt;<br><br>Why do they cost more ???

275's are a straight bosch part. No extra work needed.

The &quot;extrude hone&quot; stages I to III are injectors that have been modified, that takes time and equipment. Also the flow is matched more closely.

The &quot;EDM&quot; 's are also modified so they take time and equipment as well. And the flow is matched more closely in most cases.

If you don't have old injector bodies, you need &quot;new&quot; ones for to use....hence the core charge most of the time.


Does that explain it any better?

 

Thanks. The HP difference is a reasonable justification if it requires additional work. I really want a stage II type injector as I read on one site that they actually smoke less. By the same token, that extra cost could be put towards a Comp. I am not sure I want the wire at this point but I like the idea of adjustability on the low end. I am not after a drag truck yet but would like to bump the performance a little. DC detuning is a major source of irritation for me. Sure wish I had got the manual trans.

 

A comp alone will give you more then injectors alone. Get a box then injectors then you will take advantage of them.

KatDiesel,<br><br>Why would it cost more to make a stage 1 then a stage 3?

On the extrude hone process ( actually pushing abrasive clay through the injector to achieve the bigger holes needed) it is quite difficult to obtain a good spray pattern and high flow. It takes some more work to get the flow patterns right with the bigger holes. <br>The EDM process makes new holes. Some part of the price is also R&amp;D to produce good power on the one side and to avoid problems like delayed burn, cylinder wall washing, bowl edge burning etc. <br><br>Just my 2c<br><br>AlpineRAM
